FROM THE EDITOR | Linda Jesson December is a time for celebration, but also a time for reflection, when you find yourself thinking about the year's trials, tribulations and accomplishments. From a hydroponics perspective, Eric Hopper takes this concept even further in his latest article, “Evolution of Hydroponic Nutrients”, and examines the improvements made in hydroponic nutrients over the last decade or so, an area where he says some of the most incredible advancements in the industry have been made. Speaking of industry advancements, Dr. Robert G. Linderman returns with the second installment of his three-part series on mycorrhizae, the symbiotic relationship between specialized soil from the fungi and the roots of plants, a topic he's spent a good deal of time researching. This installment evaluates the various mycorrhizal products available on the market today and also discusses Linda Jesson inoculating plants and cultural practices that enhance or harm the formation of mycorrhizae. As for industry trends, we've included an article on biochar, a charcoal produced for use as a soil amendment or a component of a soilless mix that is believed to have a profound effect on soil dynamics. And we revisit the age-old gardening practice of companion planting. To round out the issue, we've included articles on proper hydration of cuttings, building an in-ground hydroponics system, caring for a cut or living Christmas tree over the holidays, the hydroponic forcing of witloof and an introduction to permaculture—a sustainable approach to designing and growing edible landscapes. Be sure to check out the extensive New Products section, where we showcase some great holiday gift giving ideas to keep you growing strong into 2014! Wishing everyone Happy Holidays from all of us here at Maximum Yield!

ASK The Experts

I have a question for Jennifer Casey about making the most out of waste water. I have been using reverse osmosis (RO) water for some time and am worried about the amount of waste water that comes out of it. I would like to find a use for this water and have a few options and ideas: leave it in the soil (which I think might increase the salinity of the soil, resulting in unproductive soil); use it for washing clothes or utensils; or recycle in another filter for further treatment. While researching ways to reduce the waste water and reuse the water that comes out of the RO treatment, I came across one of your articles and was impressed by the way you deal with issues and explain things so precisely. Can you help with my issue? Thank you, Bharat


Maximum Yield USA  |  December 2013

Hi Bharat, Here is a short answer: We recommend waste water be used on lawns, mature trees, shrubs and other non-sensitive plants. Reuse of waste water is somewhat dependent on the contamination of source water; source water with high ppm levels (more than 400) will produce much higher ppm waste water than source water with a lower ppm. The question posed mentioned the possibility of increased salinity; this would only be an issue if source water had salinity to begin with, which is relatively rare, or if the RO system was being used to filter water from a water softener. The only way to remove softener salts is to use reverse osmosis, the process of which would definitely concentrate that salt and could potentially build up in soil, causing damage even to non-sensitive plants. If you have a softener, it’s best to send the RO waste water down the drain. If you do not have a softener, try using it on trees, shrubs and lawns. Avoid using it for washing the car or clothing or dishes, as concentrated, hard water can cause spotting and wear out clothing. Kindest Regards, Jennifer Casey Jennifer Casey is the marketing coordinator for Hydrologic Purification Systems. Part of her job includes attending trade shows, writing articles and finding new ways to let people know how important pure water is. Jennifer loves her two dogs, her husband, the amazing garden he grows and living in the country—in that order. Crafting, reading and cooking from the garden are her favorite ways to spend her time.

Excellent Grape Exports Promotions are stepping up to support the late California grape season. The late season period (October through January) sees large volumes of California grapes exported—last season, product shipped after October 1 represented 35% of total exports for the entire season, which runs from May until January. To meet the late season export demand, there are plentiful supplies of green, red and black grapes, as a larger crop is expected this year over last season. (Source:

The preliminary crop estimate for the 2013/14 crop is 7.1 to 7.5 million 7-lb. tray equivalents. All growing regions experienced strong winds in early summer, resulting in broken canes and crop loss. All growing regions received sufficient chilling hours for the 2013/14 season. (Source:

Protecting Hawaiian Papayas While the debate rages on about the pros and cons of genetically modified crops, a research facility in Hawaii is working on developing a ringspot virus-resistant papaya—the old-fashioned way. The Oahu-based Hawaii Agriculture Research Center has received a federal grant to assist in cross-breeding a hybrid that will be resistant to the disease that ravaged the Big Island papaya industry in the 1990s. Stephanie Whalen, the center’s executive director, says the effort involves what she describes as a distant cousin of the papaya that is native to South America. Vasconcellea pubescens, also known as the mountain papaya, has shown resistance to the virus. Researchers hope to find an offspring of that match that is fertile and carries the virus-resistance gene. (Source: 22

Connecticut’s Largest Urban Greenhouse

Pitcher Plants

Boot Camp Farms founder and CEO Antonio St. Lorenzo will oversee the construction of a flagship farm and community training center on Central Avenue in the East End of Bridgeport in Connecticut where the company will turn blighted brownfields into sustainable urban farms with 80,000 sq. ft. of computer-controlled greenhouses to produce 800,000 lbs. of fresh produce per year for local consumption. The urban greenhouse will also add 40 full-time green collar jobs to the community and will be the largest hydroponic farm in Connecticut when complete. (Source:

Pitcher plants are carnivorous plants whose prey-trapping mechanism features a deep cavity filled with liquid, known as a pitfall trap. Foraging, flying or crawling insects such as flies are attracted to the cavity formed by the cupped leaf, often by visual lures such as anthocyanin pigments and nectar bribes. The sides of the pitcher are slippery and may be grooved to ensure that the insects cannot climb out. Through a mechanism of digestion, the prey is converted into a solution of amino acids, peptides, phosphates, ammonium and urea, from which the plant obtains its mineral nutrition (particularly nitrogen and phosphorus). Carnivorous plants occur in locations where the soil is too poor in minerals or too acidic for most plants to be able to grow. (Source:

growing tips, news and trivia

The Root of the Matter Lateral roots, as the name implies, are secondary roots that grow laterally out of a plant’s main root, much like branches grow out of the trunk of a tree. The arrangement of these roots is determined by a complicated combination of environmental signals based on the availability of nutrients and water in the surrounding environment, hormonal signals and external stimuli. The presence and strength of each of these signals act as a cue to the plant, which can then make a decision about when and where to form a lateral root. A new study on nitric oxide, commonly thought to be an important regulatory and signaling molecule in plant root formation, has found that nitric oxide may in fact have the opposite effect as previously found and might actually inhibit root branching.

Taking a Good Foodie Photo Considering taking and posting pictures of your hard-earned yields? The one thing you can do to make your food photos look better is to use natural light. Don’t use overhead lighting, which casts a yellow greasy-spoon look to a plated dish, and definitely don’t use an on-camera flash. Set your dish near a window and turn off any nearby artificial lights. The indirect light from a window will illuminate your food just right. Try to photograph with the light at your back or to the side of a dish, so that the shadows are to the side or behind it. If you have a window that lets in loads of direct sunlight, you can cover it with a white sheet to soften the light. You can also use a white sheet or white poster board facing the window to bounce light back on the shadowed side of the food, filling in those shadows with a little bit of extra light. (Source: 28

Speeding Up Sweet Potato Harvests A machine designed by a group of Mississippi State University researchers could help sweet potato farmers reduce skinning injury to potatoes and speed up harvest. The undercutter prototype, made from off-the-shelf components, shows early potential to help lower harvest and post-harvest losses caused by skinning, says Jason Ward, assistant extension professor in MSU’s Agriculture and Biological Engineering Department. Problems stemming from skin abrasions that happen during digging and handling account for 20 to 25% of storage losses. The undercutter digs below the surface with a V-shaped blade to cut the roots that feed the potato from the soil. This stops the flow of nutrients and water to the potato and induces a state of shock that causes the skin to toughen. (Source:

Maximum Yield USA  |  December 2013

A hunger-relief agency’s pledge to build America’s first non-profit supermarket was greeted skeptically at first. However, Philabundance may be confounding local doubters. Its Fare & Square grocery store, seven years in the making, recently opened its doors in Chester, a low-income area lacking ready access to healthy food. Usually in the business of distributing donated food to pantries in the Delaware Valley, Philabundance has augmented its mission and become a store owner, charging prices eight to 10% lower than small urban grocers. Anyone can shop at the 16,000-sq. ft. store, but low-income people will be offered an advantage. Shoppers with annual incomes equal to or less than twice the federal poverty level of around $23,000 for a family of four can accrue 7% store credit each time they shop, to be applied toward future purchases.

Xtreme Gardening CalCarb Foliar Booster CalCarb is the key to dense fruit and flower development. CalCarb is a unique form of calcium carbonate plants are able to absorb through foliage and quickly convert into calcium and carbon dioxide. Calcium is critical to plant health, contributing to the strength of cell membranes and regulation of nutrient use. CO2 is basically jet fuel for photosynthesis, allowing for higher growth rates and heavier yields. Unlike other sources of CO2, CalCarb does not require machinery or regulators, just simply spray the underside of plant leaves once a week and watch your plants take off. CalCarb works from inside the cell wall of leaves, meaning it does not require a sealed room. It can be used both indoors and outdoors. CalCarb helps shield plants from powdery mildew by raising the pH on foliage and can be used with any nutrient line. Use CalCarb and Spray on the SunshineTM. Now available in 15-lb. bags. Visit a local retailer for more information.

Aquaponic Worms

F.A. Q. in

Many people are surprised to hear that worms are an important part of an aquaponic system. Sylvia Bernstein explains why and answers a few frequently asked questions. 50

Maximum Yield USA  |  December 2013


AQUAPONIC WORMS Anyone who has taught courses or given presentations about media-based aquaponics has experienced the unique reaction people have when they are told that worms are an important part of the ecology of an aquaponic system. The expression that spreads over their faces reveals a mental connection being made between the futuristic coolness of aquaponics and the comforting familiarity of traditional, soil-based gardening. For many, this linkage is the final piece they needed to become convinced that aquaponics truly is a natural system. But often you will see that expression followed by a frown of skepticism. How can a creature that normally lives in terra firma possibly survive and thrive in the watery environment of an aquaponic grow bed? We get a lot of questions like this about worms and their use in aquaponics, so I thought it was a good idea to dedicate an article to the most frequently asked questions about aquaponic worms. Here goes…

Worms are an important part of the ecology of an aquaponic system."

Q: How do worms benefit my media-based aquaponic system? A: They break down the solid waste from the fish, and excess roots and other materials that plants slough off, and make nutrients from these materials available to the plants through their excrement—vermicompost. This additional


Maximum Yield USA  |  December 2013

metabolic layer in media-based systems is what allows media growers to avoid both the requirement to filter out solid waste and the requirement to frequently clean out their grow beds. A 12-in. deep grow bed with a healthy population of worms will probably only need to be cleaned out every few years. Vermicompost, and the tea that results from soaking vermicompost in highly oxygenated water (such as the conditions


AQUAPONIC WORMS found in an aquaponic grow bed), have been studied extensively by the Soil Ecology Lab at Ohio State University and found to aid in the following pest and disease issues: • Suppresses plant diseases, including pythium, rhizoctonia, plectosporium and verticillium • Suppresses parasitic nematodes • Suppresses insects and pests such as tomato hornworms, mealy bugs, spider mites and aphids

Q: How do worms survive in an aquaponic grow bed? Don’t they drown? A: We have all seen worms crawling out onto the sidewalk after a soaking rain, seemingly gasping for air. That they choose exposure to the sun and hungry birds over the water-logged soil seems to tell us that worms don’t like soaking wet environments. And what is an aquaponic grow bed if not a soaking wet environment? The difference with aquaponics is that they do not remain constantly full of water, but rather flood, and then drain. This allows for a drying-out period between soakings that also encourages air circulation within the grow media. This brings me to the most important reason why worms thrive within aquaponics—oxygen. The reason why those worms crawl from the soil to their death on the sidewalk is not because of the water, but because the water has forced the oxygen out of the soil. In aquaponics, not only does the flood and drain action pull oxygen into the grow bed media, but the water that is circulating throughout the system is highly oxygenated. In fact, I’ve found worms thriving within my sump tanks.

A 12-in. deep grow bed with a healthy population of worms will probably only need to be cleaned out every few years."

Q: Can you ever have too many worms? A: Sadly, no. My fish certainly wish there were too many worms! But the fact is that worms naturally adjust their population to match the conditions within their environment and as soon as those conditions no longer support additional worms they slow down or stop reproducing.

Q: I’m considering a system inside my home. Will they escape? A: Again the answer is no. Worms hate the light and are happiest in the moist darkness of your grow beds. The only time you will see your worms once they are in your grow bed is


Maximum Yield USA  |  December 2013

when you pull out a plant. They will be intertwined in the roots taking care of sloughed-off dead root material.

Q: I heard that worms can carry E. coli. Is this true? A: No. Only if it is present in whatever media they are living in. In fact, worms have been shown to mitigate pathogens that affect humans. An April 15, 2010 article in the Journal of Environmental Protection titled “Earthworms: Charles Darwin’s Unheralded Soldiers of Mankind” stated: “The earthworms also release coelomic fluids that have anti-bacterial properties and destroy all pathogens in the waste biomass [13]. They produce ‘antibiotics’ which kill the pathogenic organisms in the waste and soil where they inhabit and render it virtually sterile. It was reported that the removal of pathogens, fecal coliforms (E. coli), Salmonella spp., enteric viruses and helminth ova from sewage and sludge appear to be much more rapid when they are processed by E. fetida. Of all E. coli and Salmonella are greatly reduced [14].”



Q: How do I introduce the worms into my grow beds? A: You should exercise common sense with the introduction of anything into your aquaponic system, whether that be a pest control spray (even if it is organic), new fish (quarantine first!) or a new source of water or media. Accidentally introducing manure from warm-blooded animals that might harbor diseases such as E. coli. into your aquaponic system would not be smart. However, I have been told by our worm vendor that most responsible vermiculturalists rinse their worms after removing them from their compost home, at least twice, and then they use peat moss to ship them. He said that it doesn’t make sense to ship worms in manure or compost because it gives off heat and high heat is the biggest risk when shipping worms. That said, if you buy your worms from a less-than-professional source, or you harvest them from your own compost pile, you should clean the worms of

anything sticking to them before introducing them to your aquaponic system. Better yet, purge their systems (guts) by putting them in wetted-down cornmeal for 24 hours (or use oatmeal or wetted-down Cream of Wheat). Then wash off the worms, and introduce them into the aquaponic system by laying them on top of the grow beds. They will quickly crawl into the media to escape the light.

A Closer Look at Christmas Tree Care

For those who opt for a cut or living Christmas tree during the holiday season, the care and culture of the tree while it is indoors is critical for its prolonged use, and possibly its future life in your landscape. 58

Maximum Yield USA  |  December 2013


Bringing the forest inside The debate over buying real versus fake Christmas trees has become almost as cliché as choosing paper or plastic, boxers or briefs. Whichever side you are on, there are a lot of facts that are lost in the debate. A live tree refers to any tree that is grown as a crop on a farm or plantation for the purposes of either being cut down (a cut tree) and used as a Christmas tree, or a tree that has its roots intact (a living tree), and has been dug out of the ground with the intent of transplanting it into another location at another time. A fake tree is manufactured out of synthetic material. If you opt for a cut or living tree, the care and culture of it while it is in your home is critical for its prolonged use, and possibly its future life in your landscape.

BRINGING A CUT TREE INSIDE THE HOME Your cut Christmas tree is going to be a part of your family for several weeks. Even though your tree does not have roots anymore, it will still take up water and respire as if it did for a short time, and you can help to prolong this state. Clear an area for your tree that is away from any heat source such as a

fireplace, wood stove, radiator or register. These speed up the drying out process of your tree and reduce its useful life as well as increase its chance of becoming a fire hazard. If you cut the tree yourself, you can take it inside right away. If the tree has been bound with twine or subject to the elements for a while after being cut, you may need a period of acclimation for your tree. While the tree is still outside, cut the twine so branches can settle. This allows a chance for any chipmunk or other animal that may have taken temporary residence in your tree to scamper away. It also allows any ice or snow to melt and any field debris and dead needles to fall out before bringing it in. Next, make sure your tree stand has an adequate water reservoir. Your tree may drink as much as 1 gal. of water per day at first, and reduce its consumption as the days and weeks progress. If your tree ceases to take up water, and you still require its services prior to Christmas, it may be necessary to remove it from its stand and give it a fresh cut along the bottom. The sap may have clogged up the tree's pores and blocked its ability to take up water.

“If the tree has been bound with twine or subject to the elements for a while after being cut, you may need a period of acclimation for your tree.”

USES FOR YOUR CUT TREE AFTER THE HOLIDAYS Once your tree has executed its duty faithfully, it can still serve useful purposes that will keep it out of a landfill. A discarded Christmas tree can become shelter and a habitat for a variety of birds and wildlife. You can stake it up in the yard and hang a bird feeder from it. You could also just toss it aside and let the animals find it themselves. Christmas tree branches can be cut up and placed over top of overwintering perennials. The added insulation can help get them through the winter and provide structure to collect falling snow if you live in a northern climate, which adds protection from freezing temperatures. The trunk of your tree can be used as a fence post or stake and the branches could be added to a compost pile. If you are so inclined, a formerly loved Christmas tree may add an element of whimsy to your garden.

CARE OF A LIVING TREE IN THE HOME If would rather purchase a living tree so you can plant it in your yard later, there are a series of steps that will help to make sure your tree survives. Living, coniferous evergreen trees are not conducive for prolonged life inside your home. They need to be acclimated to your home’s environment prior to being brought inside, and can only stay a few days so they do not break dormancy and begin to grow inside. If possible, bring the tree into a garage or unheated porch for several days prior to being brought in and then repeat the process on the tree's way out. Before you bring it in the house is the time to prepare its home for after the holidays. It is good practice to dig the planting hole before you bring the tree inside. You don’t want the tree’s roots exposed to freezing temperatures by being above ground once it is outside. If you cannot properly plant the tree until the spring, putting the tree’s roots in the ground and heavily mulching will keep it alive and healthy until it can be planted.

Bringing the forest inside


“If you cannot properly plant the tree until the spring, putting the tree’s roots in the ground and heavily mulching will keep it alive and healthy until it can be planted.”

Like a cut Christmas tree, keep a living one away from heat sources. Avoid tricking the tree into thinking that it is now spring to prevent it from breaking bud and start growing for the year. Do not allow the tree to dry out, but do not over-water. Unlike a cut tree, which should be taking up a large volume of water over the course of its time in your stand, a living tree should be moistened before coming into the house, but then watered only if there is risk of the roots drying out. To determine this, insert a knife or other object four to six inches into the root ball and check to see if the soil is moist. Do not rely on the apparent moisture of the outside of the roots. You can keep a living tree inside the home for longer periods if you keep it in a cool environment.

POST-HOLIDAY CARE After you have acclimated your tree back to colder temperatures, take the tree out to the pre-dug hole. If the ground is not frozen, plant the tree as you would in the spring or fall. If the ground is frozen, it is critical to keep those roots insulated. Mulch around the tree’s base with pine bark, straw, wood chips or anything you can mound at least 3 to 4-in. thick. The excess can be removed in the spring, and aesthetics should not be the concern at this time. Water the tree as soon as it is practical. If the roots are dry and allowed to freeze, there is a good chance your tree will not emerge out of the winter alive and well.

OTHER LIVING TREE OPTIONS FOR GROWING INSIDE If you want a live or living tree, but cannot use a traditional evergreen tree, you have several options, many of which are suitable houseplants year-round in any climate. The Norfolk Island pine (Araucaria heterophylla) is an excellent substitute and can be grown indoors. It is not an actual pine tree, but it is a coniferous evergreen, and can be decorated and lit up for the holidays just like any other traditional tree. They are quite common in garden centers and anywhere houseplants are sold. Rosemary plants, which are often pruned into a conical shape, are becoming a popular alternative and can live on inside the home for many years as an addition to your kitchen garden. Many other herb plants can be used as well. There is no law that says your Christmas tree has to have needles. A jade tree, an arboricola or any member of the fig family could be made jolly with the addition of some lights and ornaments, and return to service as your household foliage plant after the holidays.

GROWING YOUR OWN CHRISTMAS TREES Starting your own mini Christmas tree plantation can be a fun way to ensure you will have a supply of varieties you like for many years. You will not be able to raise them indoors (if using traditional evergreen species), but you could get them started inside. Evergreen seedlings are often plentiful in early spring. If you buy them in bulk, they can be obtained for as little as a dollar or two per piece. Create a potting mix that is acidic and drains well and pot each one individually in a gallon-sized 62

“Christmas trees help to control erosion, act as a wind block, help to clean the air by absorbing carbon dioxide and give off oxygen.” nursery container. Water them as you would a house plant, until it is warm enough to place them outside. They can spend their first full year in the pot. Allow them to go dormant in the winter by placing them in a garage or by burying the pot for the winter to protect their roots. Seedlings can be planted in the field (or your yard) in early spring. Allow 8 to 10 ft. between each tree and shear them in mid-summer to keep their growth compact and conical.

A FINAL NOTE Christmas trees are a crop, just like corn, pumpkins or berries. They are planted to be harvested. Because they stay in the ground an average of seven to 10 years each, they do a lot of good for the environment. They help to control erosion, act as a wind block, help to clean the air by absorbing carbon dioxide and give off oxygen. And, since Christmas tree farmers are business people, for every tree that they sell, they will be planting at least one, and maybe five to 10 trees to replace those sold. Buying a real tree helps the environment and supports small agri-businesses in your community. The process of selecting and cutting down a tree or taking one home with its roots intact can also be a fulfilling family event to add to the celebration of the holidays.

PAR Plants is for

by David Kessler

What works best for us humans is not always best for the plants we are growing in our gardens. David Kessler explains light from a plant's perspective. 64

Maximum Yield USA  |  December 2013


Lumens are for humans It blew my 10-year-old mind when my all-knowing grandmother told me that the blue jay we were watching was in fact not blue. She explained that light is composed of many colors, and it is the colors that are reflected, not absorbed, that our eyes perceive as the color of an object. This is a necessary reminder that what is perceived might not be what it appears to be. For decades, the indoor gardening community has used lumens as the standard increment for the measurement of light. Lumens were unfortunately a poor choice, and here’s why.

“Lumens are essentially a measure of brightness based on human perception. A lumen is equal to the light emitted by one candle falling on one square foot of surface located one foot away. ” Lumens are essentially a measure of brightness based on human perception. A lumen is equal to the light emitted by one candle falling on one square foot of surface located one foot away. This measurement presumes a human is the perceiver of the light. Plants perceive light differently; from a plant’s perspective, light that is useful for photosynthesis is not necessarily bright. Light– more specifically, visible light– is made up of wavelengths of energy on the electromagnetic spectrum ranging from 380 to 770 nm (nanometers). Plants use wavelengths from 400 to 700 nm for photosynthesis. Brightness does not accurately describe if the light will be more or less useful to a plant.


Maximum Yield USA  |  December 2013

“Color temperature is often referred to in the horticultural industry on lamp boxes to describe the color of the light emitted by the lamp.” Light can be characterized in other ways when discussing its benefit to plants. Color temperature is often referred to in the horticultural industry on lamp boxes to describe the color of the light emitted by the lamp. Does 4,000 K grow a plant better than 7,500 K? Color temperature is listed in Kelvin (K), which is a measurement of temperature. The temperature of what you might ask? It is a description of the relative whiteness of a piece of tungsten steel when heated to that particular temperature in degrees Kelvin. This accurately characterizes the color of the light as we perceive it, but color temperature again fails to address how effective a particular light source will be at providing the energy necessary to drive photosynthesis.


Lumens are for humans But not to worry, there is in fact a measurement that precisely describes how effective a particular light will be for growing plants– PAR, or photosynthetic active radiation. PAR spectrum accounts only for light, or more precisely, photons emitted between 400 to 700 nm. Scientists have concluded that it requires about nine photons to bind one CO2 molecule in photosynthesis. Even though blue photons have more energy, scientists have also found that there is little difference between the effectiveness of red versus blue photons at driving photosynthesis as long as the photons are within the 400 to 700 nm range. This leads to a direct correlation between the number of photons produced in the PAR spectrum by a given light, and the photosynthetic potential of that light.

“there is in fact a measurement that precisely describes how effective a particular light will be for growing plants—PAR, or photosynthetic active radiation.” Photons are emitted by light sources in large numbers so we do not talk about billions or quadrillions of photons; instead we refer to them using the multiplier moles, which stand for 6.0221415 x 1,023. To make the numbers even more accessible, the number of moles is often divided by one million, resulting in micro-moles. Light sources emit photons continuously over time so the number of micromoles is more accurately described as μmol per unit of time (most commonly, seconds).


Maximum Yield USA  |  December 2013

When trying to quantify how effective a light source is beyond the total output of μmol/second, you must consider one last piece of information– the size or area of your garden. Inevitably some of the photons produced will not reach your garden, so the most accurate representation of a light source’s ability to drive photosynthesis will take into account the area being lit and how many photons reach that given area per second. The formula that represents the effectiveness of a light source for photosynthesis is written as μmol/sq. ft./s. This descriptor is actually referred to as photosynthetic photon flux density, or PPFD for short.

“When trying to quantify how effective a light source is beyond the total output of μmol/second, you must consider one last piece of information— the size or area of your garden.” In light of all of the information above, let’s remember that lumens are not a useful descriptor of a light’s ability to drive photosynthesis. I think I will sit back with a drink and digest all of the information about PAR and PPFD while I watch the not-blue blue jay outside my window.

SEEDS AND MERISTEMS Seeds are amazing storage containers that allow a plant to travel through space and time. Inside each protective casing is a tiny plant held in stasis until it is exposed to conditions that initiate development and growth, along with some stored energy (endosperm) for the plant to get started with. The miniature plant inside often has either one seed leaf or a pair of seed leaves. Along with the seed leaf (or leaves), the miniture plant inside the seed shell also usually has a pair of growing tips (apical meristems), one at the top of the stem (hypocotyl) that develops into the first true leaves at the top of the sprout, and one at the tip of the root (radicle) used for root development. Meristem cells are unusual in that they are a basic building block cell that can differentiate to become different types of cells depending on need and environement. Meristem cells can divide and generate new cells, an ability that becomes lost when they differentiate into the type of plant cell they ultimately become. Stems, leaves, roots and flowers all start as undifferentiated meristem cells that have differentiated into the various cells needed to form the plant parts and organs. Although meristem cells can transform into different cells, once a cell type is determined, it loses the ability to become one of the other types. In a nutshell (pun intended), a seed coat protects a tiny plant that already has a root, stem and a leaf or two. The metabolism of the plant is slowed dramatically, and dehydration stalls development. The embryonic plant is well developed and alive in a viable seed. If the plant dies, or is fatally malformed, then the seed is dead and will not sprout. Some varieties of plant seeds remain viable for years; others are best used the following season. In general, moisture is bad for seeds unless they are being sprouted. Moisture can enter into the seed through small holes in the seed coat called micropyles where it can stagnate and encourage anaerobic bacterial and fungal growth. Most seeds prefer to be stored in a dry, cool location until used. Under proper environmental conditions, moisture entering the micropyles will induce sprouting. If the micropyles are deformed or blocked, germination may be difficult. To assist in sprouting such seeds, they may be soaked in water before

planting, or a small nick may be made in the seed coating (scarification). A small cut opposite the hinge side of the seed can be made to allow moisture to be absorbed. An alternative to cutting the seed coat is to weaken it by scraping the seed against a bit of sandpaper or emery board. As the dried plant takes up the water, it starts to grow. Since the tiny plant is no longer in stasis, it begins to need warmth, moisture and air. In fact, it becomes dependent on them. One way to reduce the number of weeds in a garden plot that relies on irrigation is to water an area so the weeds sprout, and then kill off the tender sprouts by allowing the area to dry out. Once seeds have started to sprout, they must either grow or perish. As the tiny sprout grows, it bursts through the seed coat. The radius spreads underground to become the root system. The seedling leaves will unfurl, the seed coat will drop off and the shoot apical meristem (growth tip) will develop the first true leaves and begin normal growth. Shoot meristems are usually indeterminate and will continue to grow as long as conditions permit and flowering is not triggered. Primary meristem cells add to the height of the plant and the length of the roots, while secondary (lateral) meristem cells add to the girth of the trunk, branches and roots. Many plants have the ability to not only produce a main apical meristem, but also develop lateral growth tips. Plants that exhibit apical meristem dominance will produce a dominant shoot off the trunk that will inhibit the development of the side branches. By removing or pinching off the main apical meristem, lateral growth is encouraged.

SEEDS AND MERISTEMS This is often done to encourage bushier growth. Catnip is an example of a plant that responds well to pinching. While catnip's normal growth habit is a long shoot with a large floral cluster at the top, if pinched back, lateral growth is encouraged, and it will produce several smaller clusters, making for a bushier and more attractive plant. Another important use of the apical meristem is in vegetative propagation (asexual reproduction). In many plants that have multiple growing tip nodes, undifferentiated meristem cells in the stem can develop into root tips. Air layering is one method used. In air layering, a branch is bent downward and a section of it is buried. The growth tip on the end of the branch is allowed to develop normally, but the buried meristem cells develop into root tips. Once the branch has established roots of its own, it can be cut from the parent plant and become independent. When taking cuttings from plants, remove a growth tip and branch from the parent plant and bury the stem for a similar result. The main difference between air layering and cuttings is that with air layering the branch continues to receive support from the parent plant, whereas with cuttings the growth tip is separated from the parent plant before the roots are established. Cuttings tend to need a lot of moisture to survive, at least until they have developed a root system of their own. Cuttings are particularly sensitive to drying out and terminally wilting. They must not be kept too wet or fungal problems such as rots can develop

before the plant can become established. To assist in rooting, sometimes a rooting hormone auxin such as indolebutyric acid or naphthale-

By removing or pinching off the main apical meristem, lateral growth is encouraged.” neacetic acid is used. Although many cuttings will take directly in soil, it is not uncommon to start cuttings in a deep water culture, aeroponic or hybrid system. Tomato plants are usually easy to reproduce by cuttings and can be helpful in “proof of concept” attempts at rooting cuttings. Note that taking cuttings of certain patented life forms may be illegal, so only take cuttings from heirloom or other legal issue-free plants. Some plants naturally use a reverse air layering technique to self-propagate. They send out shallow roots (runners) that can become exposed, triggering root meristem cells to become shoot meristem cells. This will cause new shoots to develop from the root, which may remain connected to the parent plant, or develop independently if the root connection becomes severed. When a plant becomes sexually mature during flowering, the meristems at budding nodes differentiate into floral meristems. It is the floral meristems that create the flowering and reproductive organs that are used in normal sexual reproduction in plants. To summarize, inside each seed is a small plant, living and waiting for conditions to initiate sprouting. Germination triggers meristem cell division, used for plant growth. Meristem cells are the stem cells of the plant world. They are important throughout the life of the plant from the tiny, embryonic plant encased in a seed coat, to a mature plant forming flowers and fruits.

What’s Your

Hydration Status?

by Bill DeBoer

Examining the Hydration Status of Softwood and Semi-Hardwood Cuttings Proper hydration is paramount to an individual’s success rate with cuttings. Softwood cuttings are especially sensitive, but semi-hardwood cuttings should be regarded as well. Here is Bill DeBoer with some good tips on how and why to rehydrate those precious, delicate cuttings. 76

Maximum Yield USA  |  December 2013

Hydration status

“A cutting experiencing water stress or lower hydration will have a smaller chance of root formation relative to one that is fully hydrated.”

Most green thumbs who propagate plants by cuttings are concerned with relative humidity, temperature, rooting hormones and media type. While all of these factors play an integral role in the success or failure of rooting, there is one factor that growers may be overlooking: water status. It is so simple and ambiguous that I would argue it is rarely, if ever, addressed by the propagator. So, why do we care about how much water is retained in cuttings? In the case of softwoods, and to a lesser extent semi-hardwood cuttings, proper hydration will directly impact turgor pressure. When the turgor pressure of a softwood cutting is high (in hydrated plants), the cuttings will feel rigid. Cuttings with low turgor pressure (as a result of water stress) will have a soft feel and will be noticeably wilted. A cutting experiencing water stress or lower hydration will have a smaller chance of root formation relative to one that is fully hydrated. Let’s explore some reasons why proper hydration is so important to the success of root formation on cuttings.

No roots and leaves? We may have a problem Roots are a plant’s organs that take up water and nutrients. A combination of water and nutrients is pulled up the plant through the evaporation of water from the leaves. Therefore, a plant’s cuttings will pump water out and become desiccated quickly. Water stress will lead to biochemical signaling events that can partition energy away from reserves that would go toward root formation. In addition, the stress response can lead to the abscission or dropping of leaves in an effort to reduce water loss. Collectively, both factors will significantly reduce the odds of successful root formation.

Leaf abscission (drop) If the leaves are the source of water loss, why should it matter if they drop off? Won’t that help reduce water stress? Plants are certainly adaptable to certain stressors, and dropping leaves is a natural response 78

Hydration status or cessation (during prolonged and extreme drought conditions) of a plant’s metabolism or the biochemical reactions needed to sustain normal functioning. Maintaining adequate hydration throughout the rooting process will reduce these negative events. Fortunately, there are ways to level the playing field and make sure all of the cuttings start off on the right foot.

How we can rehydrate

“Plants are certainly adaptable to certain stressors, and dropping leaves is a natural response to water stress. But things are not so black and white when we are dealing with a section of a plant.” to water stress. But things are not so black and white when we are dealing with a section of a plant. As you might already know, a plant’s main energy source (sugar) is produced in the leaves by using light energy, carbon dioxide and water. Eliminate the energy producing factories and the cutting will not have sufficient reserves to manufacture roots. Total failure will result. While saturated photosynthesis running on all cylinders is disadvantageous due to nutrient requirements (no roots to take them up), you do not want a complete shutdown either.


Maximum Yield USA  |  December 2013

Stress is costly To ensure the highest probability of successful rooting of plant cuttings, a grower must minimize energy sinks and water loss while promoting factors leading to root formation. Water is a lifeline to all levels of proper plant health, and water stress can be viewed as a decline in health. Think of the times when you are fighting a cold. How energetic do you feel, or how well do you perform other tasks? In this example, your body is expending considerable resources trying to fight off these invaders. Water stress will cause a slow down

Is simply placing the cuttings in a beaker of water enough? That may be adequate, but let’s look to the world of the florist to understand what factors will help promote fast, efficient water uptake. Cut flowers are often treated with hydration solutions. A hydration solution may contain any or all of the following chemicals: water, an acid, a germicide and a surfactant. The role of water is obvious, while acids have a two-fold purpose. Lowering the pH level to between 3 and 5 facilitates an opening of the conductive tissue (xylem/phloem), as blockages to the xylem will greatly slow down or completely block water uptake. To this end, make sure you re-cut each plant cutting underwater so that an air embolism or bubble does not form. Lowering the pH also helps to reduce microbial growth, which may or may not be paramount in this application. Next, a germicide will help sanitize microbes that have colonized the cut end or stem of the cutting. Using a germicide may provide dividends down the road in preventing fungal or bacterial infection that can rot the cutting. Lastly, a surfactant may accelerate the speed of water uptake by reducing surface tension. While this may help, I personally don’t believe it is necessary for re-hydrating plant cuttings.

How long to wait While there are significant anatomical differences across plant species, the total length of the cutting will be the largest determining factor in determining how long rehydration will take. As a general reference, a 2 to 3-in. cutting should fully rehydrate within 15 to 30 minutes.

Hydration status

“While some cuttings will respond favorably to simply being immersed in water for rehydration, others will benefit from the addition of an acid or a surfactant to keep the conductive tissue clear and to accelerate water uptake.”


Maximum Yield USA  |  December 2013

In Conclusion Proper hydration is paramount to an individual’s success rate with cuttings. Softwood cuttings are especially sensitive, but semi-hardwood cuttings should be regarded as well. The purpose of this article is to stress the importance of maintaining proper hydration of plant cuttings. If a plant is fully hydrated, subsequent rehydration will be of little use. Remember, the role of water in cuttings is multidimensional. Water accumulation within plant cells exerts pressure against the cell wall, which creates the rigidity that keeps a plant upright. Loss of water pressure due to dehydration leads to wilting. Since cuttings do not have roots to uptake water, and a callus will eventually block uptake from the cut portion, the leaves will quickly become a major source of water loss, resulting in wilting and failure of the cuttings to root. Stressors like dehydration can promote undesirable consequences like leaf abscissions or drop that will also decrease root formation. Stress is metabolically costly in that partitioning of resources to alleviate the stress will ultimately be taken away from the energy pool needed for rooting. While some cuttings will respond favorably to simply being immersed in water for rehydration, others will benefit from the addition of an acid or a surfactant to keep the conductive tissue clear and to accelerate water uptake. Even though it is not commercially available, rehydration solutions for cuttings could offer a potential vehicle, reinforcing leaves and thereby reducing leaf drop as well as delivering water soluble compounds promoting root initiation. While the traditional factors of relative humidity, temperature, rooting hormones and media type are quite important when it comes to growing using cuttings, make sure those thirsty cuttings are fully hydrated, and I know you will be happy with the results!

Trimmi Christmas cactus plants By Heather Rhoades

With its brilliant blooms providing a splash of welcome color over the holiday season, a Christmas cactus is a pleasure to have around the house in the winter. But what if it grows too big for the space you've allotted for it? We have the solution...

Because Christmas cactus plants are so easy to care for, it is not uncommon for a Christmas cactus to eventually grow to a monstrous size. While this is lovely to see, it can create problems for a homeowner with limited space. The solution is to prune the plant. Christmas cactus pruning is not just for large plants, either. Pruning a Christmas cactus, large or small will help it to grow bushier, which in turn results in more blooms in the future. So whether you are looking to simply reduce the size of your plant or make yours look even more beautiful, keep reading to learn more about how to trim a Christmas cactus. 84

Maximum Yield USA  |  December 2013


When To Prune Christmas Cactus Plants The best time to prune a Christmas cactus is right after it has bloomed. At this time, the Christmas cactus will be entering a growth period and will start to put out new leaves. Pruning a Christmas cactus right after it blooms will force it to branch out, which means the plant will grow more of its distinctive stems. If you are not able to do your Christmas cactus pruning right after it blooms, you can prune the plant anytime from after it blooms until late spring without doing harm to the Christmas cactus plant.

“you can prune the plant anytime from after it blooms until late spring without doing harm.” How To Trim A Christmas Cactus Because of the unique stems, pruning a Christmas cactus is perhaps one of the easiest pruning jobs there is. All you need to do is give the stems a quick twist in between one of the segments. If this seems a bit harsh on your plant, you can also use a sharp knife or scissors to remove the segments. If you are pruning a Christmas cactus to reduce its size, you can remove up to one third of the plant per year. If you are trimming Christmas cactus plants to make them grow in more fully, you only need to trim one or two of the end segments from the stems. The really fun thing about trimming a Christmas cactus is that you can easily root the Christmas cactus cuttings and give the new plants to friends and family.

evolution of hydroponic nutrition Indoor gardeners have witnessed many technological advancements over the last few years. While strolling through almost any indoor gardening retail store, growers see various new lighting technologies, state-of-the-art atmospheric controllers, complex, ready-to-use hydroponic systems and ventilation and filter equipment. As a hydroponic store owner, I witnessed many new customers walk in and quickly become mesmerized by the various high-tech gadgets. These newcomers did not even realize they were walking right past some of the most incredible advancements in the industry. This is because these products didn’t have flashing lights or colorful boxes. Although many have fancy labels, all are destined to be stored in a plain container on a shelf with many other plain containers that appear no different at first glance. I am, of course, talking about the bottles containing hydroponic nutrients that line the walls of the local hydroponic store.

Growers often walk by bottles of nutrients as they gaze at the latest and greatest inventions to hit the indoor horticulture market because nutrient bottles lack a certain satisfaction that only a tangible object can give. I am not saying that gardeners don’t understand the importance of using quality nutrients, but sometimes development of those nutrients is taken for granted. After all, hydroponic nutrients, like indoor gardening hardware,


evolution of hydroponic nutrition

have evolved immensely over the last 10 years. There have been major breakthroughs in the methods used to extract, create and culture various nutrients and supplements. Nutrient manufacturers are paying closer attention to the way their products interact with each other.

“One of the discoveries that greatly affected the hydroponic nutrient industry was the invention of chelated nutrients for plants.” In other words, more attention is being placed on how combining nutrients affects the end nutrient solution. Manufacturers are paying closer attention to the habits of the growers as well, which influences the way hydroponic nutrients are designed. There have also been major discoveries regarding the microscopic world in and around the plant’s root mass. These discoveries have had a tremendous impact on the evolution of hydroponic nutrients. Many hydroponic nutrients and supplements now include beneficial micro-organisms in their formulation. Over the last decade or so there has been a lot of development that has influenced the way we view hydroponic nutrition. Each of these developments deserves its own recognition as being a major contributing factor in the top-notch fertilizers available to today’s indoor horticulturist.


Maximum Yield USA  |  December 2013

Che l a t e d p l a n t n u t r i e n t s One of the discoveries that greatly affected the hydroponic nutrient industry was the invention of chelated nutrients for plants. Many growers use fulvic and humic acids because of their ability to chelate organic compounds and aid in nutrient absorption. Scientists figured out a way to take this naturally occurring phenomenon and re-create it in the laboratory. This occurred in the early 1990s and since then has changed the way our plants take in nutrients, especially micronutrients. The process of chelation describes a way that particular ions and molecules bind with metal ions. Many of the essential micronutrients found in a plant’s diet are metals that, when chelated, can be absorbed more easily and used more efficiently by the plant. To create chelated micronutrients for hydroponics, the desired micronutrient is combined with fulvic acid, ammonia and hydroxy acid, and in some cases heated, until the desired metal chelates form. After the chelates are formed, a stabilizer is added and the chelated nutrients can be added as an ingredient to a fertilizer or supplement. Chelated plant nutrients are stable and can be used in any hydroponic system, including high oxygen systems like aeroponic or top-drip systems. Chelated nutrients can also be used effectively in a foliar feeding program.

evolution of hydroponic nutrition

pH stabilizers Few parameters affect nutrient uptake in a hydroponic system as much as the solution’s pH. In fact, there is a desired pH range that hydroponic gardeners must stay within for their plants to uptake nutrients at all. One of the biggest frustrations for hydroponic gardeners is the constant battle trying to stabilize the nutrient solution’s pH. Nutrient manufacturers are starting to understand that creating a pH-stable product is as important to creating success for the hydroponic grower as anything else. Some nutrient manufacturers have begun to add pH stabilizers to their nutrients to help curb undesired pH fluctuations. Other nutrient manufacturers are constantly testing and reformulating their products so they work synergistically without causing pH stabilization issues.

“Some nutrient manufacturers have begun to add pH stabilizers to their nutrients to help curb undesired pH fluctuations.”

Amino acids Amino acids are essentially the building blocks of plant life. They are required for virtually every plant function to occur and are directly linked to a plant’s metabolism. Many amino acids are produced by the plants themselves and contribute to the synthesis of cellular molecules, including chlorophyll. Plants grown in less than desirable conditions experience stresses that cause amino acid production to be hindered, which, in turn, causes stunted growth or reduced yields. By supplementing amino acids, a grower can help to negate the effects of many of the everyday stresses that may occur in an indoor garden, before they affect the plant. Hydroponic nutrient manufacturers are not only adding amino acids to many fertilizers, but are also creating specific amino acid supplements so the grower can add them as needed or desired. It wasn’t necessarily the discovery of amino acids themselves that influenced the evolution of hydroponic nutrition, as much as the discovery of how to effectively extract the desired amino acids. Enzymatic hydrolysis extraction of amino acids is one of the most influential discoveries to affect plant health in hydroponic systems. It allows for the separation and concentration of L-form amino acids that can be used to amend existing fertilizers or create powerful stand-alone additives.

evolution of hydroponic nutrition

Be n e f i c i a l m i c r o - o r g a n i s m s Our further understanding of the complex symbiotic relationships between a plant and the micro-organisms living around the plant’s roots has played a pivotal role in shaping modern hydroponic nutrition. Some of the hydroponic nutrients are broken down into a readily available form and actually bypass the need to be broken down by a micro-organism. This does not mean that the plant does not benefit from supplemental beneficial micro-organisms. Aside from aiding in breaking down nutrients, micro-organisms stimulate root growth and defend a plant’s root zone from pathogens. Many hydroponic nutrient companies offer micro-organism supplements. These can range greatly and be either specific (sometimes containing one particular strain or one type of micro-organism for a specific purpose or benefit) or more generalized (containing a mix of various micro-organisms for a more general benefit). Micro-organisms used for indoor horticulture can be broken down into three categories: mycorrhiza, trichoderma and bacteria. Each category contains many individual strains or varieties that can have varying benefits to plant growth. Each discovery made regarding these beneficial microbes and how they interact with plants (and each other) has contributed to our current understanding of plant nutrition and will contribute to the future of hydroponic nutrients.

“By supplementing amino acids, a grower can help to negate the effects of many of the everyday stresses that may occur in an indoor garden, before they affect the plant.” Enzymes Enzymes are specialized catalysts responsible for numerous chemical reactions happening in and around a plant at all times. Catalysts are substances that accelerate the rate at which a chemical reaction occurs. Enzymes, like other catalysts, are able to increase the rate of chemical reactions by lowering the energy required for the reaction. What makes enzymes different from other catalysts is their selective nature—enzymes only react with one particular substrate. Some of the specialized reactions created by enzymes are of great interest to the indoor horticulturist. Root stimulation and breaking down organic matter (dead root matter) are probably the two most common reasons indoor horticulturists use enzymes in a hydroponic system. Enzymes have become intertwined with many fertilizer regimens so growers could be using enzymes and not even know it. Some nutrient manufacturers sell enzyme formulas for a specific purpose, such as controlling or treating pythium, or for more generalized supplementation, such as root stimulation or maintaining root health. 94

evolution of hydroponic nutrition

“The future uses of nanotechnology in indoor horticulture could include improving the plant’s ability to absorb nutrients and the molecular treatment of diseases and pathogens.” Nanotechnology One of the newer technologies sure to influence hydroponic nutrition in the future is nanotechnology. Nanotechnology is the manipulation of matter on an atomic and molecular scale. It is possible that some day all of our hydroponic fertilizers could be greatly influenced by this type of technology. The future uses of nanotechnology in indoor horticulture could include improving the plant’s ability to absorb nutrients and the molecular treatment of diseases and pathogens.

The e v o l u t i o n c o n t i n u e s Hydroponic nutrition is in a constant state of evolution. Over the last couple of decades, we have seen our heightened understanding of plant nutrition, how pH affects nutrient uptake and how the relationship between plants and micro-organisms influence the way hydroponic nutrients are designed and used. There are always new technologies or discoveries just around the corner. Although the various hydroponic nutrient manufacturers are competing against each other, they are all inadvertently working together to bring the grower the latest and greatest breakthroughs in plant nutrition. It is not just the manufacturers that play a crucial role in the evolution of hydroponic nutrients. The growers themselves test and experiment with various combinations to find the best nutrient regimen for their individual needs. There is no sole determiner but instead it is the combination of the scientific discoveries, the manufacturers and the growers that together shape the continuous evolution of hydroponic nutrition.

Tips and Tricks

The Myth of

Night Light

by Dr.Linda Chalker-Scott


Maximum Yield USA  |  December 2013

True or False? Unless you’re a poinsettia, increased light can’t hurt. Read on to find out...

The Myth Anyone who grows poinsettias and Christmas cacti knows that controlled light exposure is crucial for flower bud development. I heard a nightmarish story last year about a student intern who inadvertently turned on the lights of a greenhouse dedicated to poinsettia production; the entire crop was ruined as flower initiation was delayed past the holiday season. Other than these specialty flowering plants, however, the effects of artificial lighting on plant materials are rarely considered. Two of the high-quality characteristics of an urban or suburban environment are healthy green spaces and substantial night lighting. These two characteristics are most noticeable along streets and in parks. If anything, one might expect that this additional light (especially high-intensity lights) would aid nearby trees and shrubs by prolonging photosynthesis. This is certainly effective in greenhouses—why not landscapes?

The Reality Plants that have evolved under a regime of seasonal changes are exquisitely adapted to these changes. While temperature and water levels can fluctuate dramatically throughout the year, the changes in

day length are constant and predictable. Summer solstice represents the longest day of the year—or, in the case of plants, the shortest night. As the summer continues, day length shortens and nights lengthen. Temperate plants cue into this shift and at a particular light-to-dark ratio will initiate biochemical changes to prepare for winter dormancy. An uninterrupted dark period is critical for this process as well as for flower bud initiation in certain plants. In general, the harsher the winters, the earlier these changes occur, thus allowing native trees in colder environments plenty of time to become cold hardy. When urban trees, especially street trees, are exposed to extended light periods, those leaves and buds nearest the source perceive an endless summer—and keep on growing. While this phenomenon is difficult to see initially, in the autumn it is quite distinctive: affected leaves retain their green color while those leaves under natural conditions have already started to senesce and change colors. When the first autumn frosts arrive, these green leaves die and the tree loses the resources that normally are scavenged during senescence. Recent research has demonstrated that high-intensity light sources, such as high-pressure sodium lamps, have the greatest impact on delaying leaf

senescence and subsequent dormancy of landscape trees. What does this do to the health of the tree? While the long-term effects of altered light periods on street and other urban trees have not yet been studied, the loss of resources puts a small but repeated strain on the tree. This could be manifested by reduced growth compared to similar trees in more naturally lighted environments, or by a die-off of roots most closely associated with the affected branches. Trees in optimal settings probably won’t be affected, but those in marginal areas with poor soil conditions are more likely to become susceptible to other stresses or opportunistic diseases. And, of course, flowering can be disrupted in landscape plants as well as in poinsettias.

The Bottom Line • Artificially prolonged light periods can interrupt flowering cycles and delay winter dormancy. • Marginally hardy plant materials should never be exposed to interrupted dark periods. • Consider the location of high-intensity light sources (such as street lights and security lights) before installing shrubs and trees. • The effects of high-intensity lights can be partially moderated by installing deflectors on the lights.

Biochar, or charcoal produced for use as a soil amendment or a component of a soilless mix, is believed to have a profound effect on soil dynamics. Read on to learn all about the benefits of biochar.


Maximum Yield USA  |  December 2013


The rediscovery and ongoing experimentation with biochar, a charcoal specifically produced for use as a soil amendment and soilless mix component, is one of the most fascinating dimensions of contemporary horticulture. Fueled in part by research on terra preta in the Amazon Basin, or ancient soils cultivated by pre-Columbian aboriginal populations, interest in this unique material is expanding exponentially worldwide. Academia, industry and individuals alike are investigating various methods of producing, processing and incorporating biochar into various soil ecologies and growing methods.

“biochar is best understood as a catalyst that continues over time to modulate and improve soil dynamics.” Properly manufactured biochar has a set of distinct and unusual properties believed to have a profound effect on soil dynamics, with benefits including increased nutrient availability and uptake; reduced watering and nutrient requirements; suppression of soil-borne disease; stimulation of systemic plant disease response; increased overall plant growth, vitality, health and yields; improved aeration, drainage, and porosity; improved soil flocculation and structure; prevention of nutrient leaching; stabilization of pH; and increased cation exchange and water-holding capacity. Biochar can also decontaminate soil and is being studied and used for photo submitted

remediation efforts. Biochar will isolate and detoxify soil contaminants by absorbing heavy metals, allelopathic (plant-produced) and pathogenic (bacterial/fungal-produced) toxins, and chemicals such as pesticides and herbicides. This list is far from complete, and many of the more ardent and vocal advocates hail biochar as the ultimate horticultural, energy and climate panacea. Overall, biochar is best understood as a catalyst that continues over time to modulate and improve soil dynamics. Biochar is being studied for its potential ability to sequester large amounts of CO2 gas, mitigating the effects of global warming by acting as an effective and long-term carbon sink. The scientific research is hardly 10 years old, and although there remains an adequate number of credible, peerreviewed studies to validate the claims, some of the published literature shows conflicting results. This ability to boost agricultural productivity without additional petrochemicals while ameliorating climate change has led to an increasingly impassioned debate. The pyrolitic process used to produce biochar can also be harnessed to provide cleaner energy, but aside from whether biochar might be the Achilles’ heel of global warming, it is scientifically verifiable and practically demonstrable that it does benefit overall plant health. This multi-faceted material deserves increased focus and study. Without doubt, what is known about biochar pales significantly in comparison to what is not known; the science at this point has identified causative effects, but not necessarily the underlying modalities and mechanisms responsible. This scientific deficit opens the door for opportunity and

experimentation by the individual grower. Contemporary attempts to recreate terra preta soil, or engineer new versions, is known as terra preta nova. Use of biochar in hydroponic systems is a fledgling practice, virtually untouched by academia, but it is safe to assume many of the same results can be attained by using it in the grow substrate, mixing biochar powder in the reservoir, or using it as a foliar feed. Pyrogenic, carbon-based agriculture is not a recent development—it has a long and storied history as a method used by indigenous cultures in many parts of the world including Africa, Australia, Europe and, most notably, by the pre-Columbian peoples in the Amazon Basin. For decades, scientists and archeologists remained perplexed as to how these cultures could sustain such massive populations given the rapidly declining soil conditions immediately following removal of the native rainforests for swidden agriculture. <Biochar is known to isolate and detoxify soil contaminants by absorbing heavy metals.

breaking down biochar Scientists found patches of soil ranging from one to several hundred hectares in size and 7- to 10-ft. deep that exhibited exceptionally high fertility—some of the most fertile soil ever discovered on the planet. These areas stood in stark contrast to the nearly infertile reddish or yellowish clays left following removal of the rainforest. After years of intensive research and analysis, scientists determined that these soils were intentionally cultivated by these pre-Columbian populations using waste agricultural biomass, fish and animal bones, pottery sherds, excrement and charcoal. It was also determined that these peoples manufactured biochar specifically for amending soil, and did not simply include remnants from fire pits. They were practicing what we now know as organic, ecological or biological agriculture, far in advance of what their European counterparts were capable of at the time.

“Biochar is being studied for its potential ability to sequester large amounts of CO2 gas, mitigating the effects of global warming by acting as an effective and long-term carbon sink.” The dark earth of the Amazon exhibits nearmystical properties, including elevated levels of nutrients, minerals, active bacterial and fungal biomass, soil humus, humic and fulvic acids and elevated paramagnetic and cation-exchange capacity. The terra preta also demonstrated the ability to regenerate and grow after mining and removal, and even the ability to support years of continuous crop cultivation without additional fertilizer inputs. That the exceptionally high fertility remained despite 2,000 years of latent inactivity and exposure to unrelenting, torrential rains confounded scientists at the time. Ultimately, investigations into terra preta led to the identification of biochar as the principal change agent, although the research and debate continues. Contemporary research has identified the properties that most likely make biochar so beneficial to soil ecology, though much remains to be learned. It is a light but solid material made up of 90% carbon, produced through a specific process known as pyrolysis, or the chemical decomposition of organic matter in an oxygen-deprived environment. Organic matter such as dead plant refuse, weeds, leaves, manure, bones and wood chips provide the biomass from which the charcoal is made. 106

It is this subsequent porosity and the accompanying surface area, which can range from 4,000 to 12,000 sq. ft. per 0.04 oz. of char, from which the sorptive capacities are derived. This powerful action allows biochar to absorb and store copious amounts of nutrients, minerals, humic substances, plant root exudates, oxygen, water and other essential elements for microbial and plant nutrition. The carbon structure of the char is highly resistant to decomposition, providing favorable habitat that is readily colonialized by beneficial bacteria and mycorrhizae. It is believed that biochar can last thousands of years in the soil with minimal erosion, decomposition or lability.

In a biochar reactor or kiln, the organic matter is heated to anywhere between 450 and 900°F, and due to the lack of adequate oxygen, the organic matter does not fully combust. During the thermal process, numerous physical and chemical changes take place. The cellulose of the plant material becomes fossilized, capturing the carbon that would otherwise decompose and enter the atmosphere as carbon dioxide. The process is not as complicated as it may sound—biochar can be made in the backyard, though it can be dangerous due to extreme heat and open flame. Plans for backyard or small-farm biochar reactors can be found online and are typically constructed from 50-gal. steel drums. Research suggests that the feedstock, firing duration and temperature play a significant role in determining the resulting physical-chemical structure and composition. After firing, what was organic matter becomes a pitch-black, crystalline, lightweight and somewhat brittle material.

Many of the profound benefits resulting from the inclusion of biochar in soil blends are directly related to the powerful, dynamic relationship it has with soil microbes. Following pyrolysis, the char is cooled with water but remains sterile. Whether you have made your own, or purchased raw char, several steps are necessary to accentuate the many properties that make it an exceptional catalyst for the rhizosphere-plant continuum, or the microscopic area at which biology, soil particles and roots interact. It is not advisable to use raw char without first inoculating it with beneficial biology (mycorrhizae and bacteria). Methods of inoculation include blending biochar with compost and letting it sit for three or four weeks, soaking it in properly brewed compost tea or mixing in commercially available inoculant powders, the latter of which is my preferred approach. This is a critical step, known as loading or charging, as the biology acts as a buffer to the extreme sorptive capacity of the char. Beneficial bacteria and mycorrhizae will immediately colonize the porous carbon structure and begin digesting residual tars and resins leftover from pyrolysis. Use a

carbon, likely gorging on the cache of nutrients, air and water while forming symbiotic relationships with their microbiological accomplices. The most important aspect is verifying quality of material. As biochar is often made from refuse, it is essential the biochar you select is free from contaminants. Biochar is easily crushed or broken into various sizes, from 1-in. pieces down to powders, and all sizes are useful for indoor growing. I favor the 3-mm size down to the powder simply for ease of use. Biochar can also be added to existing plants by grinding it into a powder and mixing it with water, and there is some anecdotal evidence that it is useful as a foliar in this form. It is better to add char conservatively, as even a small amount of powder can have a significant effect. There are few standard recommendations for quantity when blending soilless media, as the bulk of the research is centered on outdoor agricultural environments. In reviewing the available literature, biochar may constitute

up to 20% of the total growing media, although in my personal experience, the benefits can be realized at far lower rates, even at 1%. In addition, I have experimented with adding 5 to 10% topsoil or clay to indoor grow medias, thereby more accurately replicating what would be found in natural environments.

I recommend conventional growers cut back fertilizer use by 50 to 80% if using biochar in the soil media, which can save lots of money in the long run. Biochar is a fascinating development in horticulture, with enough evidence to prove results, but also with limitless possibilities left to the individual indoor grower to experiment and develop. I recommend all growers try tailoring their own terra preta nova or designer biochar.

To foliar feed or not to foliar feed? We have the answer... Foliar feeding is the practice of supplying nutrients to plants through their foliage. It involves spraying water-dissolved fertilizers directly on the leaves. Many believe that foliar feeding is favorable over soil application and it is associated with higher yields and better fruit quality. However, much uncertainty still surrounds this practice.

Under Which Conditions Should You Use Foliar Feeding?

How to Improve the Effectiveness of Foliar Feeding.

Under certain conditions, foliar feeding has the advantage over soil applications. Limiting conditions: A foliar feeding is recommended when environmental conditions limit the uptake of nutrients by roots. Such conditions may include high or low soil pH, temperature stress, too low or too high soil moisture, root disease, presence of pests that affect nutrient uptake and nutrient imbalances in soil. For example, micro-nutrient availability is greatly reduced in high soil pH. Under such conditions, foliar application of micronutrients might be the more efficient way to supply these nutrients to the plant.

Various factors affect the effectiveness of foliar feeding. The pH of the foliar spray solution: Nutrients must be in their soluble form for the plant to be able to absorb them. The pH affects the solubility of nutrients and their interaction with other components in the water. Generally, acidic pH improves the penetration of nutrients through leaf surfaces. In addition, pH affects foliar absorption of nutrients in three other ways:

Nutrient deficiency symptoms: One of the advantages of foliar feeding is the quick response of the plant to the nutrient application. The efficiency of nutrient uptake is considered to be 8 to 9 folds higher when nutrients are applied to the leaves compared with applying nutrients to soil. Therefore, when a deficiency symptom shows up, a quick but temporary fix would be applying the deficient nutrient through foliar application. In specific growth stages: Plants require different amounts of nutrients in different growth stages. It is sometimes difficult to control the nutrient balance in soil. Foliar applications of essential nutrients during key stages can improve yield and quality.

Limitations of Foliar Feeding Limited dosage: Nutrients applied in foliar application cannot meet the entire nutrient requirements of the crop. Phytotoxicity: Applying high concentrations of nutrients by foliar application might result in leaf burn, as water evaporates and salts remain on the leaves. High cost: Due to phytotoxicity considerations, small amounts of nutrients should be applied at a higher frequency. However, frequent applications at lower concentrations are costly and impractical.

1. The pH affects the charge of the cuticle (a waxy layer covering the leaves) and therefore its selectivity to ions. 2. The ionic form of nutrients is pH dependent, and therefore pH can affect the penetration rate. 3. The pH might affect the phytotoxicity of the sprayed compounds. We can conclude that the pH of the spray solution must be adjusted according to the applied nutrient.

Use of surfactants: Surfactants contribute to a more uniform coverage of the foliage. They increase the retention of the spray solution by reducing the surface tension of the droplets. Time of the day: The best time to foliar feed is early morning or late evening, when the stomata are open. Foliar feeding is not recommended when the temperature exceeds 80°F. Droplet size: Smaller droplets cover a larger area and increase efficiency of foliar applications. However, when droplets are too small (less than 100 microns), a drift might occur. Spray volume: Spray volume has a significant effect on the nutrient absorption efficiency. Spray volume must be sufficient to fully cover the plant canopy, but not too high that the nutrients run off the leaves.

permaculture PrIncIPleS SUSTAINABLE




BY HELENE ISBELL Permaculture is more than just a buzz word. It’s a sustainable approach to designing and growing edible landscapes. There’s a bit more to it than that though, as Helene Isbell explains…


Maximum Yield USA  |  December 2013


permaculture principles The organic food movement has secured a noteworthy position for itself in American culture, and it continues to gain momentum. Consumers, both domestic and international, are becoming privy to the importance of eating clean, organically grown food. While this is a tremendous step along the path to a greener and healthier future, large-scale organic farming can still produce many of the same side effects caused by industrial agriculture and still threatens ecological welfare. Permaculture offers an integrated, responsible solution that brings organic gardening back into the hands of individual citizens. Permaculture is a sustainable approach to designing and growing edible landscapes. Derived from the terms permanent agriculture and permanent culture, permaculture borrows practices from indigenous cultures, bridging the gap between ancient knowledge and modern horticulture. It places emphasis on working smarter rather than harder, bringing a fresh approach to intelligent garden design. A permaculture farmer focuses on building healthy soil structure rather than using chemical fertilizer, using smother weeds with mulch in place of herbicides and combating pests naturally without pesticides. The practice encourages gardeners to plant and eat what grows locally, plan for long-term sustainability, maximize the potential of small spaces of land and treat the planet respectfully with regard for future generations. Formalized in the 1970s by Bill Mollison and David Holmgren, permaculture has spread globally as an ecological alternative to conventional farming practices.

permaculture principles

Regard for

our physical Earth is essential to maintaining the integrity of global prosperity.”

Core Ethics of Permaculture

Permaculture revolves around three core tenets that characterize the foundation of the practice: 1. Care for the planet: Regard for our physical Earth is essential to maintaining the integrity of global prosperity. This includes regard for all living systems, from microscopic, such as the intricate soil web, to entire biospheres, such as forests and prairies. Without the plankton that makes up the bottom of the ocean’s food chain, there would be no fish, seals or dolphins. The well-being of humanity is dependent on the care of all life, as everything trickles down from this vital concept. 2. Care for humanity: Provide not only for oneself, but also for family, friends and neighbors. Take others into consideration in all that you do. Our society has been stripped of this notion, as increasing importance is placed on the accumulation of personal wealth. It’s time to look towards the ways of ancient cultures and revisit a tribal community mindset where people work together to meet common goals. 3. Share surplus: In a permaculture, it’s possible to grow a good number of fruit and vegetable varieties. This, however, doesn’t mean that it will be possible to produce every food you want to eat. This is where trade with other growers comes into play. By communicating with one another and sharing surplus, variety and abundance is distributed amongst many people and everyone is satisfied. Sharing is caring. 120

permaculture principles

Principles of Permaculture

Permaculture is more than just a set of technical rules to follow; it invites the gardener to interweave creativity into their relationship with natural ecosystems. Because nature differs from region to region, each garden design will be unique, adapting to local environmental conditions. Each system will take on its own appropriate characteristics while adhering to the three core tenets of permaculture. In addition to these overlying values, there is a set of 12 design principles that help further define what permaculture embodies: Observe and interact: Use common sense and follow the path of least resistance when planning a garden. Observe natural surroundings and pay attention to local conditions. Take note of seasonal patterns and the flow of wind, rain and sunshine. Try to plant what grows effortlessly in your area. This will help the garden grow with ease and minimal complications.

The goal

is to use the land responsibly so it can be preserved for future generations.”

Catch and store energy: This principle can be applied in so many ways. The idea is to conserve resources when they are in abundance for use in times when they are scarce. Examples include storing energy from the sun with solar panels so it can be used later in the form of light and heat. Catch rainwater run-off and store it in barrels for times without rain. Can and dehydrate fresh produce to preserve it for use when it is out of season. Get creative. Obtain a yield: While producing food is generally the prominent goal of a garden, it’s not the only way that you can yield something positive from the experience. By working with others, you can learn what they know and share your own knowledge so that everyone walks away that much wiser. Apply self-regulation and listen to feedback: Don’t let the fear of making mistakes stop you from starting a garden— accept advice and feedback. Learn from each process and make improvements each time around. You may have to fix the mistakes of previous land users, such as build and remediate depleted soil. The goal is to use the land responsibly so it can be preserved for future generations. Use renewable resources: Use resources that can be regenerated naturally. Our society has become too dependent on non-renewable resources such as plastic and oil. Not only do these resources pollute the environment, but once they are used up, they are gone forever. Incorporate materials into your garden like bamboo—a fast growing grass—or hemp, which is industrially as strong as plastic, yet renewable and non-polluting. Both can decompose rather than sit in a landfill for thousands of years. Produce no waste: A permaculture garden produces no waste. It operates in a closed loop system and all elements get used. For example, remnants from previous harvests, along with kitchen scraps, turn into compost to fertilize future crops. Worms consume plant matter and break down nutrients making them bioavailable to new growth. Imagine having no waste. 122

Design from natural patterns: Pay attention to patterns in your natural surroundings. Nature is not angular, but rather curvy, soft and fuzzy around the edges. Garden beds don’t need to be symmetrically shaped rectangles placed at evenly spaced intervals; they can be round, oblong, spiraled or flower-shaped. Crops don’t have to be planted in rows. Mimic nature for a truly beautiful individual garden design. Integrate rather than segregate: Strategically planting crops together encourages co-operation among species rather than competition. A polyculture is several plant varieties growing together, versus a monoculture (a single large crop), and helps with the natural give and take of nutrients, rather than quickly depleting the soil. Companion planting is the practice of planting different plants in the same bed that will mutually benefit each other. A great example of companion planting is the trio known as the three sisters used by Native Americans throughout North America and consisting of corn, beans and squash. Beans fix nitrogen into the soil for the corn to use in its vigorous growth, and the shallow-rooted squash provides natural mulch, preventing moisture evaporation. Corn provides a natural pole for the beans to climb, creating a harmonious combination. Food forests are an example of polyculture on a larger scale known as agroforestry. A food forest would include many fruit trees, shrubs and other edible plants growing in unison for a multi-layered harvest. Use small and slow solutions: Patience is a virtue, and permaculture teaches this. Permaculture relies on long-term solutions rather than the quick fix, paying off with greater

value in the end. An example of this is planting perennials rather than only annuals. Perennials are plants that return every year on their own. Once established, this means less work for the gardener and less disruption of the soil microsphere. Another example would be to save seeds rather than buy them every time. Make sure to select organic, non-GMO varieties to ensure that they will reproduce. Use and value diversity: Planting many varieties will help ensure the overall survival of the garden by decreasing vulnerability. With fewer crops, they are more susceptible to disease and fungi and if infected, the whole garden could suffer. Integrate beneficial insect attractors and natural pest deterrents throughout the garden to naturally balance insect populations that share the habitat. This is called integrated pest management (IPM) and it is permaculture’s alternative to chemical pesticides.

Integrate beneficial insect attractors and natural pest deterrents throughout the garden to naturally balance insect populations that share the habitat.”

Use the edges: This can be interpreted in a number of ways, but basically, make use of all available growing space. Take advantage of walls and fences to grow vertically, and the sides of garden beds or dark nooks and crannies to grow mushrooms. Get innovative with small areas to maximize potential.

Creatively use and respond to change: Change is inevitable, not only in the garden, but in society as a whole. Being able to creatively adapt to changing conditions is an important aspect of being able to survive what the future holds. Just as weather patterns may change, so too may the political and social environment of a community. Be prepared to shift and adjust accordingly so that slight variations, in any form, won’t interrupt your course. It requires inquisitive and thoughtful individuals to incorporate the ethics and principles of permaculture into their mindset. It takes patience, understanding and humility to experiment and grow throughout the process. But it does get easier with time. Permaculture is more than a sustainable approach to creating edible ecosystems; it builds community, promotes sharing and brings people closer together. It can be implemented virtually anywhere, on any scale. Furthermore, it can be a deep-rooted solution to many of the environmental crises our planet faces in the name of agriculture. Besides that, what is more liberating than being able to grow your own food in an ecologically and socially responsible way? So dig in, start your garden and get downright dirty. 124

End of the

Tunnel? Is the future of LED (light-emitting diode) technology for the horticulture industry bright? David Kessler has the answer... We have all seen the plethora of advertisements in magazines about LED grow lights. When LEDs first hit the horticulture market, they were little more than Light-Brite™ toys with expensive price tags and big promises. They claimed that each watt of LED lighting was equivalent to more than 10-w of HID lighting, on top of which they asserted LEDs would produce no heat, have better penetration of light through the canopy and that the technology would revolutionize the growing industry. Unfortunately, the early LEDs were unable to deliver on most of their promises.


Maximum Yield USA  |  December 2013

LED stands for light-emitting diode. Unlike traditional light sources with delicate filaments, electrodes or pressurized, gas-filled lamps, LEDs are solid state electronics, and as such are more robust and longer lasting. Solid state by its most simple definition means made without any moving parts. A flash memory card is a solid state device, whereas a typical hard drive is not. By not incorporating moving parts into the design, solid state electronics are less likely to break, wear out or malfunction.

This added level of reliability is one of the biggest benefits of LEDs. Current LEDs are rated for as many as 70,000 hours of operation before they reach the point where replacement is advisable. Although they t will still be working at that point, at 70,000 hours of Ligh row ge G l Sta operation they will have reached a 30% reduction in Dua luminous output, making it cost effective to replace them. Seventy-thousand hours means that a grower using LEDs will not change the diodes for almost 16 straight years, running 12 hours per day, every day.

LED Grow Light

LEDs have not always had the longevity and reliability they are able to deliver today. The history of LEDs being used in horticultural applications started in the late 1980s with crude arrays of red-only (660-nanometer) LEDs. Early experimentation with LEDs in horticulture was driven by their potential for use in growing food for space travel. In the late 1990s, the crops research group at the Kennedy Space Center conducted several studies on the yield and physiological response of several crops to LED lighting. LEDs became even more promising with two critical advances in LED technology: the advent of blue LEDs and high-output diodes. The advances in LED technology keep on coming. Each decade, LED prices have fallen by a factor of 10, while their performance has grown by a factor of 20, a phenomenon known as Haitz’s law. So it seems the future of LEDs is getting brighter!

Witloof must be grown in the dark during the second stage of production to remain blanched.

Ever wondered what those creamy white leaves were in your gourmet salad? Or the bullet-shaped, leafy, pale vegetable grilled and served at a fancy restaurant? Chances are these pale delicacies are Belgian endive (Cichorium endiva), also known as witloof, which, despite its name, is actually a type of chicory—something we are more familiar with as a leafy salad green.

“While this is a relatively little known crop in the United States, it has a long history of cultivation in Europe.” Belgian endive goes by many names depending on where it is being sold. These include French endive, white endive, Dutch endive and witloof chicory. While this is a relatively little known crop in the United States, it has a long history of cultivation in Europe, where it has been produced and valued as a delicacy since the 1800s. Witloof is unlike any other vegetable we grow hydroponically and its unique value and sophisticated flavor are gaining popularity within gourmet vegetable markets.

Developing chicons arise from the apical buds on the tap root system under hydroponic forcing conditions.


“What makes witloof such a fascinating crop is that it has two stages of production.”

Maximum Yield USA  |  December 2013

What makes witloof such a fascinating crop is that it has two stages of production. The first takes place as with other salad greens, growing the chicory plants through to maturity. Under commercial production, this is done out in the field from spring to fall. This particular type of chicory develops a large tap root, similar to a thickened parsnip that is cut, harvested, washed and placed into refrigerated storage until it is required for hydroponic forcing. The second stage involves stacking the bare, clean chicory roots into hydroponic trays, through which nutrient solution flows. This process takes place entirely in the dark so that the shoots that form on the roots are blanched white in colour. The white buds (called chicons) are harvested at certain stages, depending on market size requirements, and packaged into cartons to maintain complete darkness. Any light during the growing or shipping process will result in the chicons developing green pigmentation, making them unmarketable.

Witloof history and uses Blanched witloof is a crop that was discovered by accident. In the 1800s, a farmer in Belgium discovered the chicory roots he was storing in his dark cellar over winter to be ground into a coffee substitute sprouted pale buds with creamy colored leaves and a delicate flavor. Early on, long before the development of hydroponic methods, the witloof roots were forced using a soil or sand medium piled over the top of the harvested and trimmed tap roots. The sand excluded light so the chicons formed in darkness. At harvest this had to be scraped back, and the resulting witloof carefully washed. Hydroponic forcing eliminates the need to cover the roots with any granular substrate, so the process of chicon formation can be easily viewed and the resulting buds are free from any grit contamination and don’t require washing. The additional nutrition provided from a well-balanced hydroponic nutrient solution also assists with flavor, quality and prolonged shelf life of the harvested chicons.

“Hydroponic forcing eliminates the need to cover the roots with any granular substrate.”

Under commercial production, witloof is produced in a tiered hydroponic tray system to maximize yield from the growing area.

A delicacy from the dark

“Witloof flavor is unique and highly valued in a range of different dishes.” Witloof roots are stacked side by side in hydroponic trays.

Witloof flavor is unique and highly valued in a range of different dishes. While green leafy endive and chicory foliage typically has a bitterness that some find unpleasant, the blanched chicons lack any strong flavors and are described as mild, but distinctive, tangy, tender and unique. Generally, the whiter the witloof is, the milder the flavor. Used as a raw vegetable, the small inner leaves can be added to baby leaf salads and larger leaves are used as elegant wrappers for fillings of crab, caviar, tuna or shrimp, or served with a range of dips. Witloof is also served cooked in a wide range of dishes, including soups, and a simple entrée can be created by cutting the chicon directly down the middle lengthwise, brushing with olive oil, grilling until tender and serving with lemon or vinaigrette.

Whitloof chicory is grown from seed that can be obtained from many vegetable seed suppliers. Suitable varieties are Zoom, Flas and Totem F1. Seed is sown directly where the plants are to grow as transplanting can damage the young tap root system. Seedlings need to be thinned to 4 to 5-in. apart when large enough to do so. This is an important step as overcrowding of the plants will reduce the size of tap root that develops, which in turn reduces the yield and quality of chicons that develop during the later forcing stage. Witloof plants can be given a standard grow hydroponic nutrient formulation during the first few weeks of development, followed by a bloom formulation or P/K booster as the tap root starts to develop. Ideal day length is 12 to 16 hours with moderate temperature conditions needed to produce the highest quality root system (55 to 77°F). These conditions replicate the outdoor conditions received by the plants, which are typically sown in spring. Tap root production usually takes around 110 days, but this may be sped up under the controlled conditions of an indoor garden. Harvesting of the chicory roots can take place as soon as they are mature and of a sufficient size. Maturity can be determined by examining a vertical-cut section of the root, just below the plant crown. Mature roots will have a white section, approximately a quarter-inch thick in this region. If the white region is smaller than this, the root is not mature enough for later hydroponic forcing. The best quality roots will be 1.5 to 2 in. in diameter at this stage.

Hydroponic witloof: first stage While large-scale, commercial production of witloof roots for forcing typically takes place outdoors, the plant can easily be grown hydroponically during both the first and second stages of production. Witloof chicory grows in much the same way as the endive and chicory plants commonly grown as salad crops. A deep-bed hydroponic system is required to ensure the large, thickened roots can develop without restriction. Suitable growing mediums are fine-grade coco fiber, perlite/vermiculite mixes, granulated rockwool and similar substrates in a growing bed or container at least 1.5-ft. deep. 132

Chicon development typically takes around 20 to 22 days under ideal conditions.

“Witloof roots can be refrigerated for up to 10 months before being removed and bud growth forced.”

At harvest, the green tops are cut from the plant to remove as much foliage as possible without harming the growing buds at the top of the tap root. The root system can then be removed from the growing substrate and lifted, with any loose media brushed off. In preparation for storage, the roots can then be washed. They may also be treated with fungicide to help prevent rotting if they are to be kept for several months before forcing. Witloof roots can be refrigerated for up to 10 months before being removed and bud growth forced, as they remain dormant under cool conditions. Once given warmth and moisture in the form of a nutrient solution, the dormant apical buds will start to grow during the forcing process.

Hydroponic witloof: second stage Hydroponic forcing of witloof to produce chicons must take place in complete darkness if high-quality, creamy white, blanched chicons are to be produced. Any light will result in greening of the chicons arising from the production of chlorophyll, which changes the flavor and lowers the quality of the witloof. Under commercial production, hydroponic systems are run inside enclosed sheds with double-door entries to prevent any light from entering. In an indoor garden, witloof production can take place under benches or enclosed, lightproof boxes used to cover the developing buds. Hydroponic systems for witloof forcing set up in dark cellars or other areas can also work, particularly if an indoor garden is being lit to grow other plants and can’t be used for this process. 134

“This yield ensures that harvested witloof chicons are considered a high-value delicacy and a niche market crop.”

Once the witloof tap roots are removed from cold storage, they are trimmed to a consistent length of 6 to 8 in., packed side by side into deep trays, and a nutrient solution is applied so that it flows through the roots and out the base of the tray. Nutrient solutions used during the forcing process provide essential nutrients for healthy bud and foliage development, giving a higher quality harvested product. At this stage, temperature is vital as it breaks the dormancy of the apical buds on the tap root system and starts the forcing process. Nutrient solutions are typically warmed to 61 to 72°F, while the air temperature is kept a little cooler at 55 to 65°F with a high relative humidity of 90% (conditions often easy to maintain in a cellar). Under these conditions, the buds present on the roots will start to develop into short, compact Witloof is prized for its pale creamy shoots of white leaves. This norcolor, delicate flavor and tender texture. mally takes 20 to 22 days under ideal conditions. During this time, air flow is required around the hydroponic system while at the same time maintaining high humidity. For this reason, fogging or misting is often used to help keep air temperatures down and prevent the chicons from drying out and developing physical disorders such as tipburn. Under commercial production, each 110 lbs. of roots being forced will produce approximately 18 lbs. of chicons, although not all buds may be of marketable quality. This yield ensures that harvested witloof chicons are considered a high-value delicacy and a niche market crop. At harvest, the chicons are carefully snapped from the roots and any loose outer leaves removed. At this stage, witloof should be 4 to 8-in. long and 1 to 3-in. wide, a whitish yellow color, compact and bullet shaped. Once harvested, the tender chicons must be cooled immediately to prevent desiccation and prolong shelf life if being stored. Commercially produced chicons are wrapped in moisture-proof paper that excludes light and stored under refrigeration at a high relative humidity of 95 to 98%. Typically these will store for a maximum of two to three weeks under these conditions.

Summary Ideally, home-grown, hydroponic witloof should be eaten within a few hours of harvest as this is when sugar levels will be highest and flavor and texture optimized. Freshly harvested whitloof chicons are a delicacy that few ever get to sample, and are a great reward for the time and effort invested in this unique crop. 136

Stunning Succulents by Karen Wilkinson

While succulents are drought-resistant plants known for their hardiness, that doesn’t mean you can leave them to their own devices. Here are some tips and tricks to keep your plants green and healthy. 138

Maximum Yield USA  |  December 2013

Succulents are plants with thick, fleshy water storage organs that have adapted to survive arid, desert-like climates throughout the world. But you can’t ignore them for too long or stick them in a dark corner and let them wither away. Succulents need love just like you and me. Succulents thrive on sunlight and heat, but too much of anything can have undesired outcomes. They’re the ideal plant if you’re looking for something inexpensive and pretty that doesn’t require lots of plant know-how. The best part is succulents can easily be propagated or cloned, either by sticking a clipping directly into soil, or by setting it in a glass of water and allowing roots to pop. From watering to the perfect potting soil, whether to plant in pairs or to simply leave them alone, I’ve compiled some of the best practices for growing succulents indoors. Because when you don’t have a back or front yard, and are stuck in urban apartment dwellings, plants can serve as a reminder that it’s not so bad. And taking care of something other than yourself just feels good and provides a sense of purpose.

“They’re the ideal plant if you’re looking for something inexpensive and pretty that doesn’t require lots of plant know-how.”

Go green When growing indoors, the greener the better. So when choosing a plant, make life easy on yourself and your plant and go green. Gravitate toward crassulas, agaves and aloe plants, while keeping the purple and orange-colored varieties for the outdoors. Some popular indoor succulents include the funky burro’s tail, the beautiful jade, the resilient snake, the ponytail palm, the fuzzy panda plant, the cheerful Christmas cactus, the medicinal aloe plant and the adorable hen-and-chicks.

Climate Succulents thrive in hot, dry environments where sunshine is abundant. Avoid placing them in a dimly-lit corner—go for the windowsill that receives the most natural light in your apartment or home (test out a south-facing window). Ventilate to prevent rotting of the foliage, and to take some moisture away from the soil. High humidity and poor ventilation are not ideal conditions, so open the windows, throw on a fan and use a dehumidifier if necessary.

Find the right light It’s all about balance, right? Succulents don’t like dimly-lit corners, but they also can be hurt if exposed to direct sunlight for too long. While they prefer bright light, you don’t want to scorch them, which can happen to some species if exposed to direct sunlight. A south-facing windowsill will hopefully be a good home, as will an east-facing windowsill. Signs of too much direct light include leaves turning brown, black or white as the soft tissues die off. If this happens, move it somewhere that doesn’t receive as much direct light. While too much light can kill, so can not enough. Underlit succulents will start to stretch (known as etiolation) and become really tall with lots of space between leaves as the plant stretches out in search of more light. The best remedy for this is to provide better light and prune the plant back to its original shape. Another tip for optimal health when it comes to lighting is to rotate the taller varieties, as they will often lean toward the sun. Keep them standing upright by periodically rotating the container.

“Signs of too much direct light include leaves turning brown, black or white as the soft tissues die off.”

Don’t crowd them Don’t crowd them In outdoor settings, succulents can thrive when planted beside one another, but when indoors and fighting for all the light possible, it’s best to space them apart, preferably in separate pots. This allows the maximum amount of sunlight to reach them. If you decide to combine succulents in the same container to create a dish garden, the secret lies in plant selection. Basically, be sure you find plants with similar growth and care requirements, so as to not disrupt their patterns.

Go easy on the watering This may be the key to your plants’ livelihood— water sparingly and allow the soil to dry completely between cycles. To prevent them from becoming water-logged, plant succulents in unglazed planters, which will help them drain completely between waterings. The thicker the leaves on the succulent are, the less water it needs. This is because water is stored there. If leaves become droopy and skinny, it’s time to give your plant a drink. Overwatered plants become soft and discolored, with leaves that turn yellow or white, or simply lose their color. Once in this condition, the plant may be beyond repair, but you should make sure. Remove the plant from its pot and inspect the roots; if they’re brown and rotted, cut away the dead roots and repot into drier potting soil, or take a cutting and clone the plant. Just as overwatering can be a death sentence, so can under-watering. During the growing season (spring and summer), succulents prefer to be watered well. Signs of an under-watered plant include stunted growth, shedding of the leaves and brown spots on the leaves. Watering is dependent upon the season—in the winter, water less frequently, and if the air is cool and dry, cut back


Maximum Yield USA  |  December 2013

watering to every two or three weeks, or even once a month. Don’t water too much at once; just give the plants enough to pacify their thirst. The general rule is to overwater during the summer and under-water in the winter. Shove a finger into the soil two knuckles deep to make sure it’s dry before watering, water enough so that the water runs through the drainage holes and empty the drainage saucer so plants don’t sit in the water.

Find the right fit While it’s OK and encouraged to pot some plants in containers that are larger than necessary, that’s not the case with succulents. They prefer a snug fit and holes on the bottom. Ideally, the pot should be at least 4-in. deep and 0.5- to 1-in. wider than the plant’s base. A terracotta clay pot is perfect for the needs of these plants.

Temperature Just because succulents are desert plants, doesn’t mean they can’t weather drastic drops in temperature. These beauties are more cold-tolerant than people may think, and in the desert survive dramatic temperature changes between day and night. Ideally, succulents like daytime temperatures between 70 and 85°F, and nighttime temperatures between 50 and 55°F, but can even thrive when the thermometer drops down to 40°F.

Soil Succulents generally have shallow roots that form densely just below the soil surface. Therefore, succulents prefer a fast-draining mixture specialized for cacti and succulents. If you can’t use such a soil, you can always modify regular potting soil with inorganic matter such as perlite to increase aeration and drainage. What you’re looking for is well-draining soil that allows your succulent’s roots to dry out between waterings. Follow these tips and your reward will be healthy, vibrant plants that provide a welcome touch of green to your home!

the potential benefits of the mycorrhizal association. Once mycorrhizae have formed, the fungal partner will go where the roots go. So the earlier the association is established, the sooner plant growth will be enhanced, and the sooner the plant will yield its products. In these cases, more inoculum is better than too little, so use enough that will ensure early and thorough root colonization. Some people want to inoculate plants already in the soil or potting medium. This can be difficult because you cannot easily deliver inoculum to as many roots as with pre-plant inoculation. Drilling holes around the plant and filling them with inoculum mixed into the soil could result in some mycorrhizae establishment, but not as much as any pre-plant treatment. Injecting fungal spore suspensions into the root zone is also possible, but mycorrhizae formation would be limited to the injection sites, and it would take time to spread to other areas of the root system. The fungus will eventually spread, but it takes longer before plant benefits are recognized.

A close-up of arbuscules (nutrient exchange sites) within root cortical cells. Mineral nutrients are delivered from the soil to the roots by the endomycorrhizal fungus and carbon nutrients, resulting from plant photosynthesis, are provided to the fungus by the plant.

Cultural practices

Once you have inoculated your plants with mycorrhizal fungi, there are some things to keep in mind as you manage your plants, specifically fertilization and pesticide applications. For most crop plants grown in soils or potting mix, fertilizers with a high amount of available phosphorous can be inhibitory, so choose fertilizers with low phosphorous in their formulation. This is truer for potting mixes than for soil. Better yet, choose organic fertilizers instead of inorganic fertilizers. And if you think you might have some root diseases, choose a fungicide that will not inhibit the mycorrhizal fungi; if pythium or phytophthora root rots are involved, most of the fungicides that target those fungi do not harm mycorrhizal fungi. For other root diseases, however, the fungicides of choice are often inhibitory. I can tell you which ones are good and those that are not good,

Hydro System Simple in-ground hydroponic systems can be an extremely cost-efficient solution for hydroponic growing. Read on to find out what you’ll need to get started.


Maximum Yield USA  |  December 2013

Building an in-ground hydroponic system can be a fun, easy, low-cost and efficient solution for producing crops. So, we’re here to help you build your very own in-ground system! Outdoor hydroponic systems are often much easier to run than indoor systems and they tolerate much more fluctuation in pH, total dissolved solids and electro-conductivity. Outdoor systems are also kinder to your energy bill and are often not as space constrained. Installing an in-ground reservoir for your outdoor hydroponic system is beneficial in many ways. The reservoir stays cooler, increasing the amount of dissolved oxygen in the solution, and thus what’s available for root intake. Dissolved oxygen drops significantly as temperatures rise over 70°F. The solution stays more temperate when buffered in an in-ground reservoir in either a greenhouse or outdoors because the ground always gravitates toward an ambient temperature of around 57°F. With water that cool, you really need to be a die-hard enthusiast to soak in one of these reservoirs. When he was younger, our son Jared enjoyed initiating new reservoirs. Brrrr!

The author’s son Jared chilling out in a resevoir.


Included with this article is a photo I took (left) illustrating everything you need to build an advanced, solar-run system (excluding the solar panels). We have built several of these on retaining walls so you can walk up to the wall and pick vegetables at chest height. We have also built some of these systems inside greenhouses.

“With water that cool, you really need to be a die-hard enthusiast to soak in one of these reservoirs.”

Everything you need to build an advanced, solar-run system.

The base system uses 1.5-in. PVC plumbing pipes and standard fittings. The configuration can be as intricate or simple as you want. The fittings do not need to be glued. The feed system we use is a standard garden drip system or spaghetti tubes connected to half-inch tubing. The hydroponic pots we use are buckets designed specifically to be fed by drip emitters. Rough plumbing can be found at any hardware store. The drip system, reservoir and buckets can be purchased at your favorite hydroponics store, online or at select hardware stores.

in-ground hydro systems Trellises can be made of hog fence or wire mesh with metal fence posts, all of which can be purchased from the hardware store. Solar panels can be purchased at certain hardware stores, online and possibly at select hydroponic stores.

Tips for building the unit

To figure out the specific items required on your material list, first measure out the run of your pipe for your overall system. Next, you’ll need to figure out your count of connecting components, such as T’s, elbows and caps, for both the system pipe and the drip tubing. The connecting components are relatively cheap, so buy a few extra to avoid multiple trips to the store. If you have an odd angle, you can use special 1.5-in. adapters. Once the pipe is laid out and the connections determined, drill 0.87-in. holes for the buckets. You will need either a 0.87-in. spade or drill bit for drilling holes in the 1.5-in. PVC main pipe. If you count on a long growing season or large plants, position the holes 16-in. to 24-in. apart. Big plants need space to grow. I’ve grown habanero pepper plants using this system, and they reached 3 ft. in soil! As a side note, one of those peppers actually seared a hole in a rubber glove, and we burned out every last person at a Thai restaurant for which we grow produce. Now that’s hot.

Buckets required for the set-up.

Next, find the lowest point of your system and dig a hole for your plastic, food-grade storage bin (reservoir). Spread sand to level out and set your reservoir. Simultaneously fill the bin with water and support around it with soil. Next, drill or cut out a 1.75-in. hole near the top for the 1-in. return pipe, and add your float valve if you want auto water. The float valve must be plumbed with 0.25-in. Pex tubing. The Pex tubing can be run in another white tube to protect it from the sun.

“I’ve grown habanero pepper plants using this system, and they reached 3 ft. in soil!”

Maximum Yield USA  |  December 2013

Any time you can use white tubing it helps lower the temperature. Keep in mind that ultraviolet sunlight will degrade Pex tubing over time if it’s not covered. For an access port in the reservoir’s lid, determine your size/plug cap requirements and cut with a hole saw or knife. You can always lift the lid rather than cut an access port. If you want a heavy-duty reservoir, ask a clerk at your favorite hydro store. If you live in a region when temperatures will drop to freezing during the winter, either drain the reservoir, or drop in a piece of Styrofoam board to keep it from freezing and cracking.


Just like standard hydro systems, in-ground systems can have added features such as solar-powered auto watering, water level sensing, TDS readouts, auto feeding and solar-powered nutrient pumping. They can be as simple or elaborate as you wish. The more automated the system, the less work once the system is set up. I gave up packing water and hoses a long time ago; plants going through a gallon an hour per plant is a lot of water to move. Certain solar water timers on the market right now have a water sensing adjustment and can be purchased as solar or battery powered and the water sensing functions can also be used for drip organic soil production.

“The more automated the system, the less work once the system is set up.”

In-ground hydroponic systems can also be run in conjunction with organic soil gardens. The solar 12-V, 380gph bilge pump will need a deep cell battery and solar panel system. If you skip the solar pumping, you can use a small mag-drive pump to run the system with low energy consumption. It’s amazing how small these pumps can be, from 280 to 500-gph, depending on the size of your system. My small solar 12-V pump ran roughly 40-ft. of hydroponically connected plants along with three tiers of organic gardens—all powered from the sun.


Simple, in-ground hydroponic systems can be an extremely cost-efficient solution for hydroponic growing. With a little elbow grease and a bit of ingenuity, you can create a really wonderful, productive unit that can be easily modified and expanded over the years. Don’t forget to incorporate solar as you experiment and grow. Happy growing!

Soaking Seeds: A How-To by Heather Rhoades

“Seeds have developed over millions of years with defenses to survive awful conditions.” Sometimes it seems to take forever for seeds to germinate. Want to speed up the process? Try soaking them first.


Maximum Yield USA  |  December 2013

Soaking seeds before planting is an old-time gardener’s trick that many new gardeners are not aware of. When you soak seeds before planting, you can significantly decrease the amount of time it takes for a seed to germinate. Let’s look at the reasons for soaking seeds and how to soak them successfully.

“When you soak seeds before planting, you can significantly decrease the amount of time it takes for a seed to germinate.” Reasons for Soaking Seeds

What happens to seeds when you soak them? Why should you soak your seeds? The short answer is because your seeds were designed to be abused. Mother Nature is not kind to a little seed. In the wild, a seed can expect to encounter harsh heat and cold, wet or dry conditions and may even need to survive through the acid-filled digestive tracts of animals. In short, seeds have developed over millions of years with defenses to survive awful conditions. But, in your modern day garden, a seed is relatively pampered. Soaking seeds before planting helps you to break down the seed’s natural defenses against what it expects from Mother Nature, which then allows it to germinate faster. While Mother Nature actively assaults seeds, she also gives those seeds an internal gauge to help them know when they should grow. For most seeds, moisture levels play a big role in alerting a seed to optimal grow times. By soaking the seeds, you can quickly boost the moisture content around the seeds, which signals to the seed that it is now safe to grow. Lastly, some types of seeds actually contain germination inhibitors that are designed to prevent a seed from germinating inside the fruit. These inhibitors must be leached away before a seed

can germinate. In nature, relying on rainfall, this process can take some time. Soaking seeds can speed this process up.

How to Soak Seeds Before Planting

Seed soaking at a basic level needs two things: seeds and water. Some methods for seed soaking may substitute the water for slightly acidic solutions, such as weak tea or coffee or even acidic chemicals. These acidic solutions are meant to imitate loosely the stomach acid of an animal, but these solutions are not necessary in most cases. For most seeds, water will work just fine. Take a small bowl and fill it with water from your tap, as hot as your tap will allow. Some seeds can tolerate boiling water, but as the tolerance for heat can vary greatly from species to species, hot tap water is safest for seed soaking. Once your bowl is filled with hot water, place your seeds inside and allow the seeds to stay in the water as it cools down. Common questions at this point include, “How long should seeds be soaked?” and, “Can you over-soak seeds?” Yes, you can over-soak seeds. Too much soaking in water and a seed will drown. It is recommended that you only soak most seeds for 12 to 24 hours and no more than 48 hours. The seeds of some species of plants can survive longer soakings, but you should only do this if the specific instructions for this species recommend it. There are things you can do to improve how well your seeds react to soaking. Large seeds or seeds with particularly hard coats can benefit from scarification before soaking. Scarification means damaging the seed coat in some way so that the water is better able to penetrate the seed. Scarification can be done in several ways, including rubbing the seed on fine grain sandpaper, nicking the seed coat with a knife and even gently tapping the seed with a hammer to help crack the seed coat. After soaking your seeds, they can be planted as directed. The benefit of soaking seeds before planting is that your germination time will be reduced, which means you can have happily-growing plants faster.

Friendlya by Russell Landry


Companion planting is a form of polyculture where certain types of crops are planted in close proximity to one another to boost crop yields or deter pests. Read on to learn more about this age-old gardening practice...

Companion planting is defined as the planting of certain crops in close proximity to each other to aid or boost crop yields and productivity. It is a type of polyculture where multiple crops planted adjacently or in close proximity can be used to promote or enhance the growth of all of the plants.

“Native Americans had the most well-known system of companion planting—the Three Sisters method of planting corn, beans and squash was used to augment each plant’s growth while supplying beneficial nitrogen, support and shade.” The practice of companion planting has proven that some types of plants do in fact grow better when they are near other specific plant species.


Maximum Yield USA  |  December 2013

Friendly types of plantings have been in use for thousands of years. First thought to be practiced by the ancient Egyptians, companion planting was practiced before herbicides and fertilizers changed our well-seasoned views about natural and effective plant propagation. Native Americans had the most well-known system of companion planting—the Three Sisters method of planting corn, beans and squash was used to augment each plant’s growth while supplying beneficial nitrogen, support and shade. Corn was planted first and allowed to grow several inches high. The corn stalk was then used as a support to hold up the beans. Climbing beans are legumes that fix nitrogen and feed nitrogen-consuming plants like corn. Lastly, squash was planted between the rows of beans and corn. The squash, being shade tolerant in the shadow of the corn, also protects the soil surface as a ground cover. Moisture conservation is achieved along with weed inhibition and reduced heat stress to all three crops. Besides the favorable aspects of companion planting, it must be appreciated that some plants cannot be effectively planted close to each other. It is known that some plants do indeed deter insects, but they can also hinder, contaminate or slow the growth rate of nearby plants. Hindering growth of companion plants is called negative allelopathy. Interfering with the growth of a neighboring plant can be problematic for the grower. However, knowing that certain plants also exude objectionable compounds that hinder root growth or seed germination is advantageous. The negative allelopathic effects of corn gluten meal in controlling the germination of weed seeds is now widely used in gardens to control weeds. The outcome of companion planting in modern gardens can go beyond protecting plants—it can reduce the need for modern control methods. The opportunity to reduce the use of pesticides, herbicides and fertilizers lowers production costs while increasing yield. Maximizing yield and fruit quality is time and again the primary goal of many gardeners. The contemporary use of monoculture, or single crop growth, has discouraged the use of companion plantings, but this narrow field of view has changed in recent times. Growers today acknowledge the limits and potential harmful effects of modern pesticides. They are becoming keenly aware that co-plantings will enhance a backyard garden plot in a more naturally effective manner while protecting the environment, and in turn they are fostering ever-increasing harvests. In some cases, companion plants are used as bait to trap unwanted insects while protecting a primary crop, often referred to as trap cropping. Growers use the pestattractive, sacrificial crops to protect a main cash crop from

infestations. For example, marigolds are often planted with tomatoes to fend off harmful, root-feeding nematodes or tomato hornworms. Hubbard squash is commonly used as a trap crop for other cucurbit-type vine crops to attract striped cucumber beetles. The beetles vector bacterial wilt or mosaic virus and can cause greatly reduced yields. Companion plants can also be planted to provide a nursery area and habitat for beneficial insects. These advantageous, incubated predator insects then move on to wreak havoc on the unsuspecting, harmful pests that feed on the primary crops. Pest-attractive plants can be used in concentrated zones in which pesticides may be used only sparingly. Insect traps and pheromone lures can also be used amongst these plantings to further reduce harmful insect populations. Hunting the harmful pests on the sacrificial crops can allow for a more targeted and efficient use of chemical controls. Planting flowers amongst the main crops can persuade pollinators to visit gardens. Honey bees, butterflies and hummingbirds will come to forage the blossoms. Vegetables like squash and cucumbers that need pollination greatly benefit in these types of plantings. Placing herbs and flowers within your vegetable patch is one of simplest ways to create this natural kind of companion planting. Cover crops can also be used as in-season companion plants. They are grown to reduce pathogens and insects or to supply nutrients. Giant vegetable growers have discovered in recent years that companion plants help boost weight gains. One of the main factors that improved fruit size is inoculating the sacrificial plants with mycorrhizal fungi. The main plant roots are colonized much faster by these beneficial fungi because the primary plant’s roots grow into the sacrificial plant’s roots and soil areas that have already been colonized by the fungi. Early season companion crops can also be returned back into the soil to increase organic matter and nutrient storage for future plant growth. The fresh organic matter then becomes food for the myriad of various and beneficial microbes in the rhizosphere. These stored nutrients will not leach away, become insoluble or get tied up in the soil. They are available when plants are actively growing and serve to boost productivity. Plants such as buckwheat sequester calcium and phosphorus. The companion cover crop can be plowed down into the soil ahead of the main plant’s growth. This supplies the developing crop with a readily available source of root-building phosphorous and fruit-bulging calcium. Nutrients are vitally important to developing plants and in-season cover crops such as legumes can supply nitrogen. Beans planted around nitrogen consumers such as cabbages and corn greatly benefit the nitrogen consumers. Nature will always endure as it fosters living communities

that stand the test of time. Observation and common knowledge indicate that many vegetables and herbs have natural compounds in their roots, flowers and leaves. These compounds may deter or fend off harmful pests and attract beneficial insects. Some plants assist other plant varieties to thrive and grow by providing shade, fungi, bacteria or conservation of water and soil moisture.

“Companion planting helps harmonize the garden’s flora and fauna, allowing the grower to use and maximize the skills that modern controls and nature provide.” The essential growth requirements of a thriving garden plot can be influenced by companion plantings. Essentially, companion planting helps harmonize the garden’s flora and fauna, allowing the grower to use and maximize the skills that modern controls and nature provide.

Getting it Down

on Paper by Matt LeBannister

A journal can help a gardener keep track of the progress of plants and compare the results of using different techniques, tools and nutrients. Matt LeBannister has the details about how keeping a garden log will make you a better gardener. 160

Maximum Yield USAâ&#x20AC;&#x201A; |â&#x20AC;&#x201A; December 2013

When I managed a hydroponic retail store, I would be hit with a litany of questions involving nutrients, media and equipment. The overall theme of the questions were, “What’s the best?” There were some things I could say with confidence that were better. Hydroponics will give you higher yields compared to soil; horticulture lamps produce better plants with larger yields than industrial lamps; and high-grade plant fertilizer will give you better results than the run-of-the-mill 10-10-10 fertilizers. But a lot of other hydroponic store items are up for debate: whether one nutrient works better than the other, which soilless mediums are ideal for each crop, and whether your plants grow better with certain additives or if you’re better off spending that money elsewhere. These questions are difficult and often impossible to answer accurately. To know exactly what result you would get, I always recommended that people experiment and keep a plant journal. Plant journaling will allow you to track progress and compare various techniques, gear and nutrients. It will allow you to document the progression of nutrient deficiency, toxicity, insect and disease symptoms and eventually come up with a strategy to maximize the potential of your garden.

At each plant feeding, one to two times per week, you also want to take a close look at the overall health of your plants. Check for signs of nutrient deficiencies and toxicities such as yellowing leaves, leaf curl, leaf tip burning and yellowing veins. You should also look closely for any signs of disease, molds or insect infestations. Catching any of these problems before they become too severe can rescue your plants and save you a lot of time and money. Plant journaling allows you to scientifically compare the effectiveness of different nutrients on your plants. First you need control plants—plants that aren’t being fed the nutrient or additive you wish to test. Then you must have plants that are being fed a measured and recorded amount of the nutrient or additive throughout its life cycle. Then you have to record the growth and overall yield of both the control plants and plants being fed the nutrients and additives to accurately gauge whether the plant growth has exceeded the growth of the control plants or not.

Plant journaling will allow you to track

No matter what, it is always important to measure your overall yield just to get an idea of how your plants are doing. If you start to notice a drop in yield from harvest to harvest, you can make adjustments or replace your bulbs. Diminished yields are often caused by the gradual decline of lumen output by your bulbs. This just happens as the bulbs are used each day.

progress and compare various techniques, gear and nutrients.”

There are many different aspects of your garden that can be documented in your plant journal. The first thing I like to check and keep a written record of is the condition of all my gear. Check your pumps and make sure that your table is flooding and even record how long it takes to flood and drain. Make sure that any drippers you are using aren’t clogged. Check your ballasts for burns and heat marks. Make sure your reservoir is not leaking and that your lights are all in working order. It is important to record when your lights need replacing and change them so your plants are not starved for light. You should make notes in you plant journal every time you water you plants or change the nutrient in your reservoirs. Record exactly what nutrients and additives you are using, how much of each and which plants are receiving what. Measure and record the pH level of the nutrient solution before watering and then measure the pH of the runoff water. Also, check and record in your journal the EC, TDS or ppm of your nutrient solution so that you can accurately adjust this if you notice any signs of toxicity or deficiency.

Don’t leave your garden to guess work. Plant journaling is the most effective way of gaining first-hand knowledge of what makes your plants grow well and is certain to make you a better gardener. Matt LeBannister developed a green thumb as a child, having been born into a family of experienced gardeners. During his career, he has managed a hydroponic retail store and represented leading companies at the Indoor Gardening Expos. Matt has been writing articles for Maximum Yield since 2007. His articles are published around the world.

10 facts on... Carbon Dioxide by philip mcintosh


Carbon dioxide

(CO2), as you may have heard, is the gas taken in and used by plants, through the process of photosynthesis, to make glucose. It’s kind of a big deal.

of CO2 rises in the atmosphere, it might be good for some, but not all, plants. Too bad it is not so good for the planet, as CO2 contributes to global warming via the greenhouse effect.

3 The CO 4

Carbon dioxide

consists of one carbon atom covalently bonded to two oxygen atoms to form a rather stable molecule.

2 concentration in the atmosphere was fairly stable at around 280 ppm up until the mid 1800s, at which time it started to rise, and it has been rising faster and faster ever since.

eukaryotic organisms, have mitochondria in their cells and mitochondria use glucose to synthesize the energy molecule ATP. Carbon dioxide is a waste product of this process. So, plants are releasing CO2 all the time and in the dark they release much more than they absorb.

gardening styles to work with these lights—replacing an HID grow light with an LED grow light means you need to re-examine everything about your garden set-up and practice. For example, because the LED light produces less heat, you may need a different fan, a revised watering schedule and a different nutrient solution due to your plants’ slower transpiration rate in lower temperatures. After explaining the why now, Sloper goes on to debunk some myths about grow lights, describes how LED lights work and what to look for when choosing one. At the end of chapter five, he includes a helpful checklist that covers off all of the elements of selecting an LED grow light, which you can bring into a gardening store or use to ask retailers about different products. For the beginner gardener, whether you are planning to use LED lighting technology or not, the second half of Sloper’s book is a must-read. He outlines everything someone building an indoor garden needs to know, including planning your grow space, the different grow systems, feeding plants and pest prevention.

Hector L. Santiago, stock manager.

One of the principle goals of The Green Box in Manhattan is bringing sustainable growing to the confined spaces common in New York City. Its owner David Ventura founded the store in 2011 after realizing hydroponics could be more than just a hobby. Amid the bright lights, concrete and skyscrapers of mid-town Manhattan is a small storefront with an inconspicuous green awning. The awning catches the eye of most people who walk past it, often beckoning them to look inside and find out what lies behind the window it hangs over. What they find is an unexpected and unique sight in New York City—a hydroponics shop and consulting agency. The Green Box is the only hydroponics store in Manhattan and one of only a few that exists in New York City. The store opened in 2011 after owner David Ventura decided to turn his hobby into his profession. After 12 years in

the fashion industry, David decided he needed a change in his life, and since he was passionate about growing, he decided to open The Green Box. “I was losing interest in the fashion industry, and had been growing my own vegetables for several years. Over the years I had gained a good amount of knowledge about the growing industry and had plenty of retail experience from working in the fashion industry. It only made sense to turn my passion into my job, so I opened a hydroponics store.” Since there were few hydroponics shops in New York City, David felt it was important to provide the growers of Manhattan with a reliable place to

purchase their hydroponic supplies, gain knowledge about hydroponic and indoor growing, and get advice on hydroponic systems. Opening a storefront in Manhattan came with its own set of unique challenges, particularly those of size restrictions, which have not slowed David one bit. The store itself is not large, but this matches the typical spaces its customers grow in. One of the principle goals of The Green Box is to bring sustainable growing to the confined spaces of New York City. Providing the supplies and knowledge of how to grow in small spaces is integral to living a sustainable lifestyle in big cities, with the added bonus of allowing people to experience food right off the plant who would not otherwise have that option. The store also provides its customers a place to interact with other growers and increase their knowledge base. It is a common event to have several people in the store discussing their methods and sharing ideas with one another. This has created an environment where people come to not only to buy their supplies, but also to learn and share. The learning does not stop with the customers: “I am constantly learning about new techniques and products every day,” says David. In 2012, manager Adam G. Sussman joined The Green Box team. Adam brought new insights and experience to the company, having spent 10 years studying and working in the theatrical production industry as well as the restaurant industry. It was this combination of technical knowledge and food

knowledge that led him to the world of hydroponic and indoor gardening. This varied background provided Adam with a unique view of the possibilities in urban gardening and he is working towards a bachelor’s degree in biology. The most current addition to The Green Box team is Steven Meyer as operations manager. Steve has come to the team from the hospitality industry where he specialized in operational development and IT solutions. His background is integral to the current success of The Green Box as he maintains the website, helps keep the store’s technology up to date and generates consulting leads. The Green Box places a strong emphasis on bringing gardens to the urban environment and educating those living in urban areas. Working with schools in and around the New York City area is one way The Green Box has encouraged the education and implementation of urban gardening. “Our work with the schools is some of the most rewarding work we are doing,” shares Adam. “Education in urban gardening and hydroponics provides young people with the skill sets to help them become part of a quickly growing professional industry.” Some of the current projects The Green Box is involved in include building a hydroponic system growing greens at the W Hotel of New York, implementing a rooftop garden at Lenox Hill Hospital, building a medicinal plant garden with Pacific College of Oriental Medicine and continual consulting with Fountain House in Manhattan. All of these projects

have a common focus: bringing sustainability and gardening into the urban environment. Food can often be the focus of urban gardening, but it is far from the only reason to garden in urban spaces. These projects also highlight the therapeutic, health and environmental benefits of hydroponics and indoor gardening. The future is looking bright for David and The Green Box. In an industry that is growing at a rapid pace, The Green Box is always looking to stay ahead of the curve and provide its customers with the best products and service it can offer. There are always new products and techniques to be developed and discovered, and it is this continual evolution of the industry that excites The Green Box team to no end. “We are looking forward to growing along with our customers for years to come,” says David.

“We Don’t Add the Biology, We Start with It!” From its home base in Gilroy, California, Xtreme Gardening/RTI is one of the world’s largest producers of mycorrhizal fungi and beneficial microbes. Here’s Ryan Miller, vice president of global sales, sharing details about the company.

Xtreme Gardening’s Pumpkin Contest winners’ entries on display.

Tell us a little about how your company started. Xtreme Gardening was born from an idea to inspire a new generation of gardeners and growers looking to maximize yield through organic inputs. John Anderson, founder of Xtreme Gardening, had learned through experience gardening with his father and mother (Neil and Maria Anderson—owners of Reforestation Technologies) that nature’s models, her designs and her processes, were the key to unlocking the true potential of plants. Neil had, over the course of his life, pioneered new developments in the forestry, restoration and agricultural fields, the crowning achievement of which was the commercial production of arbruscular (endo) mycorrhizae. John recognized the importance of his father’s technologies and decided it was time it was shared with the world. John’s father had for more than a decade, been supplying restoration companies for bioremediation, forestry services for replanting, government and city agencies for landscaping and municipalities, transportation companies for erosion control, and even a small community of competitive pumpkin and fruit growers, helping them

break World Records for plant growth, but he had not yet brought these amazing products to the doorsteps of everyday Americans. John set out with the goal of bringing this new technology, a sustainable and organic means of successful gardening, to every backyard and indoor garden in America. Little did he know, it would soon grow to reach nearly every corner of the globe.

Tell us about your products and the benefits of mychorrizae? The backbone of the product line is the Mykos, Azos and Tea Brew trifecta. We also have CalCarb, a foliar booster for density and weight; Kryptomite to battle mites and mildew and Once & Done, a new and unique way of feeding new plant starts that involves using biodegradable packets filled with premium organic and natural plant food. Mycorrhizae is the Internet super highway of the soil, absorbing and transporting nutrients and water from different areas of the soil food web to the modems (roots) and hosts (plants) that require them. There is an old adage that if you garden organically, you get a higher quality and more nutrition, but lower yield and if you grow chemically, you get a higher yield, but lower quality (less nutrition). This couldn’t be farther from the truth. The truth is that organic-based nutrients are plant and animal based and are not easily absorbed by plant roots. A fish, for example: if thrown in a hole and planted over, nutrients from the fish cannot be readily absorbed by plant roots. It must first be broken down by fungi and bacteria in the soil.   

How are your products unique?

They enhance all stages of plant growth, from rooting to flower, and may be used or combined with any nutrient program organic or synthetic alike.  

Can you explain how your products have helped achieve seven world records for fruit and vegetable yield? The big secret is in the roots. Competitive growers bury all their nodes (sites below the broad leaves on pumpkin vines that can take root) with Mykos and Azos. These microbes spark new root development, deep within the soil. Utilizing these microbes, a single pumpkin can form more than 150 separate and unique root sites to mine nutrients and moisture from the ground and put them to use (adding up to 50lbs of growth a day during peak growth). There hasn’t been

a single record-breaking pumpkin in the last six years that has not used these two microbes. The top growers have used these, as well as our Tea Brews and CalCarb foliar spray.

Is there anything happening at the R&D stage you can tell us about? We are in the process of developing new means of producing organic mycorrhizae in a concentrated form. This new technology we are pioneering has never been seen and the results and effectiveness of this process are unparalleled. I am not at liberty to dive further into this, but there has been much talk of mycorrhizae on the market, which boasts huge spore counts but are not delivering the expected results. These products are developed using genetically-modified carrot roots in labs. Essentially they are grown on “Frankenroots” that have no carrot or fruiting body attached, in a chemical hormone solution. They are able to get large spore counts, but the spores have never been exposed to real world conditions such as temperature, humidity and other microbes, and have never actually grown a plant to harvest. They are sterile and effectively impotent—most are unable to survive in the garden and have a low rate of inoculation. What we have found is a way to organically produce mycorrhizae in a fashion that has taken our spore counts to astronomical numbers. More information will be available as we get closer to bringing this product to market.

How are you able to pull all of this off? What are your facilities like? We recently moved into a state-of-theart 16-acre facility with a 96,-000-sq.-ft. warehouse, two huge labs for bacteria culturing and microbial research, one of which rivals Stanford University’s stem cell research lab, as well as two light deprivation automated greenhouses for trials, more than 16 offices and conference rooms, and enough room to grow over more than million pounds of mycorrhizal fungi per

harvest. We have dozens of machines, conveyors, loaders, mixers, driers and packaging machinery. From small-scale to large-scale packaging, we manufacture all of our products in house. We have made this growth over the last 12 months thanks to our successes in all divisions of our company, from hydroponics and garden marketplaces, to restoration, forestry, agriculture, landscaping and sport turf maintenance.

What else should we know about Xtreme Gardening? We are currently taking the agricultural market by storm. Our biologicals are negating the need for numerous applications of chemical fertilizers, costing farmers less money, while improving their yield (fruit number and weight) and quality of harvest. In tomatoes alone, the Mykos/Azos combination has increased lycopene content (an essential antioxidant) by more than 300% in independent field trials. With all the new regulations in California and across the country on the use of phosphates, nitrates and pesticides, we are helping both organic and synthetic farmers save their farms and out-produce their conventionalfarming competitors. Strawberries, which usually have a hollow and pithy center, are now growing full—red inside and out and bursting with flavor, thanks to our biologicals. Many of the strawberries, tomatoes and other produce that reaches your plate are now grown using our unique biology. Maximum Yield USA  |  December 2013
