FROM THE EDITOR | Jessica Raymond Curious where the future of modern gardening is headed? Look up, way up. Our cover feature this month focuses on the latest trend in urban farming—green roofs in urban centers. Green roofs keep food close to home, make efficient use of vacant space and offer the potential for economic growth; and those are just the obvious benefits. When you’re on the roof, the only way to go is down, which is exactly what we’ve done. Propagation, water, nutrition, lighting and grow room extras for winter—we cover a little bit of everything. Every time you step into your grow room or greenhouse is an opportunity, to embrace new ideas and practices, to

help life grow and grow your life. This is true whether you grow for people (or pets), for the planet or for profit. Growers expend their creative energy day after day, researching, testing and trialing for the ultimate goal of improving their garden’s quality, improving yields and making the seemingly impossible possible. This special issue will help you grow your best from roots to roofs. So, get reading, so you can get growing! And to keep your grow room stocked, for FREE, all winter long, enter our last Win Big…Grow Big contest for 2011. Details on page 177. Grow on!

Wishing you and yours peace, love and happiness this Thanksgiving and always. Maximum Yield Team Jessica Raymond, editor

Vermiculite is a standard horticultural substrate commonly used in hydroponics for germinating seeds and as a growing medium. The high quality grades of vermiculite sold in the United States hydroponic industry are free of asbestos, and it is recommended that only horticultural grade vermiculite be used to grow produce. Up until the early 1990s there were some products made from vermiculite that contained naturally-occurring asbestos, however, this vermiculite was largely made into insulation and other products at that time. Pure vermiculite does not contain asbestos and is non-toxic, so it is safe to use for growing beets and other vegetables. Lynette Morgan


Best magazine in the world! Anthony Leandro Can’t wait to see you in Michigan next year. Had a great time in SF. You guys are awesome. Thanks Keith Sortor

A Question of Safety

In the article by Dr. Lynette Morgan titled Old Fashioned Crops are Making a Comeback she suggests that growing mediums such as coco fiber, perlite or vermiculite be used for growing beetroots. I thought that vermiculite was asbestos-based, and its use has been banned in most countries. In that case is it safe to use it as a growing medium for crops that could be consumed. Kindly guide me in the matter. Thanks and regards, Mohan Udiavar

Hey Simon, I was thinking about trying some organics this time around but my friend told me that it makes no difference to the plants. I remember you did a question on organics before but do you think you could answer this one for me again? Thanks, James It’s an interesting question, and like many I tackle, the answer is a little gray for the indoor grower. Outdoors I recommend organics without question; the biodiversity and activity in true soils needs the interaction with organics to have great yields year after year. Indoors it is a different story. Your friend might be a chemist, and in a narrow sense he is correct. When you look at the end result, organic nitrogen and chemical nitrogen do look very similar as they enter the plant and function but that is like flipping to the last page of a book and not knowing how the story got there. Chemical products are water soluble and available; as soon as they are put in the reservoir they are available.This can be an important advantage in an indoor garden where there is not enough biology present to breakdown organic material properly.A slow nutrient release can cause problems when growing nutrient-hungry plants indoors. For this reason a chemical base should be considered by all but the most diligent indoor growers.Also by excluding organic compounds you are limiting the amount of biology in your system—both good and bad. In a much slower process, organic nutrients follow the nature of decomposition, which requires a food chain of various organisms 20

Maximum Yield USA | November 2011

to absorb, digest and secrete basic organic components. Many of the microbes sold in our industry are key components of the soil food web.Their purpose is to digest and release available nutrients for plants. While doing this, many of them also secrete beneficial substances that can tremendously benefit your plants—even indoors. Using undigested organic material requires a strong understanding of how long each organic input takes to break down. An example would be the use of blood meal, which is water soluble and can break down quite rapidly versus the use of feather meal, which has a similar level of nitrogen but can take months to actually start breaking down.Also, for those growing in true water systems the use of organic compounds should be knowledge-based and focused to avoid unwanted issues with recirculated water supply. Organics, however, do have a very serious role to play indoors even for chemical users.The important point is to focus on compounds that provide immediate and dramatic differences. Key examples are the humates, humic and fulvic acid.Although some of the benefits are still questioned most gardeners, commercial and hobby, all agree that these compounds do provide a richer soil that is more resilient and holds more nutrients in suspension for the plants. Kelp-based products can also provide tremendous benefits with all of the organic acids they contain.Worm castings are a natural way of adding plant-available nutrients and a vast array of biology into your soils.There are more quality organic products available every year so keep your eyes and ears open. If you are keen on switching to organics indoors I commend you, but would also caution you to keep a little chemical product around—a base nutrient for overall slow growth and also a calcium magnesium supplement, as a cal-mag deficiency can be a recurring issue in organic systems.A digested organic liquid is your best option for an organic base nutrient, and make sure you look beyond the basic N-P-K for things like calcium, magnesium, sulfur, iron and other micronutrients. Check with your local shop for some organic options that have proven themselves and for organically-fortified soil blends that provide some initial nutritional quality.

Pacific Islands Offer Glimpse of the Future with Aquaponics Recent studies indicate that although geographically isolated, Pacific islands like Hawaii and Kiribati could face catastrophic food shortages as a result of climate change and failing fish stocks. New aquaponics initiatives tested successfully on other islands could increase food security in the Pacific by boosting agricultural efficiency over traditional methods by as much as eight times—while using just 12 per cent of the energy and two per cent of the water. Kiribati islanders now spend about 50 per cent of their household budgets on food and the World Bank recently had to underwrite an emergency food grant of $2 million. The same study revealed that 95 per cent of food in Hawaii is imported from just a single shipping company, leaving the islands vulnerable to delivery failures and potentially just “20 meals from starvation.” (Source:

Rooftop Farms Sprouting in Brooklyn - Urban Pioneers Cater to Restaurants and Markets For consumers in New York City, ‘local’ produce has long meant fruits and vegetables from farms upstate, on Long Island or in New Jersey, but urban hydroponic growers are trying to shift that expectation by growing Bibb lettuce, basil and other leafy plants and herbs on rooftops and selling the produce to retailers and chefs. “We can harvest something in the morning and have it on the supermarket shelf or restaurant plate that same afternoon,” said the CEO of one Brooklynbased operation. Although the cost of a hydroponic rooftop can run up to about $2.5 million, hydroponic farmers are able to achieve a denser yield and harvest crops year-round and operators claim their first-year revenues can be higher “by a factor of hundreds” than those of the average soil-based rooftop farm.

Want Fresher Produce, Leave Dirt Behind Futurist Melissa Sterry Looks on the Bright Side… In a recent interview with Urban Times magazine, futurist Melissa Sterry predicted that people might one day start looking at natural disasters as opportunities rather than catastrophes, calling such cataclysmic events as earthquakes and volcanic eruptions “absolutely essential operating functions of our planet” and “Earth’s surface-recycling system.” Sterry urged city planners to build more resiliency and adaptability to changing environmental conditions into the cities of the future and suggested that humans might eventually learn to harvest “kinetic energy from floods and nutrients from volcanic eruptions, while mimicking the way in which natural ecosystems build resilience to reduce the damage such events can cause.” (Source:

Gotham Greens’ $2 million hydroponic greenhouse, located in Brooklyn’s industrial Greenpoint, has chefs singing the praises of hydroponic technology. The sleek garden is one of the largest commercial-scale hydroponic greenhouses in urban America providing pristine, sustainable produce for restaurants and high-end retailers. The water is recycled so only 700 gallons are used per day, a 10th of that used in conventional farming. Soil is replaced by thin films of nutrient-rich water sluicing down hundreds of plastic channels cradling the roots of salad greens, lettuces and culinary herbs. (Source:

New ‘Smart’ Window System Delivers Unprecedented Performance A study appearing in the journal ACS Nano is reporting that a new ‘smart’ window system has the unprecedented ability to inexpensively change from summer to winter modes, darkening to save air conditioning costs on scorching days and returning to crystal clarity in the winter to capture free heat from the sun. Although ‘smart’ windows that reflect sunlight away from buildings in summer and switch back to full transparency in winter are already in use, they have many drawbacks—including high cost, rapid deterioration in performance and manufacturing processes that involve potentially toxic substances.

Using Nitrogen-Fixing Plants to Restore Abused Garden Soil In a recent informal experiment, Simon Watkins of Permaculture Magazine discovered that he could remediate heavily abused garden soil by planting it with alfalfa. (Source:

What Counts is the Water That Actually Enters Plant Roots To help farmers make the best use of limited irrigation water in the arid West, agriculture researchers are helping farmers determine how much water major crops actually need. Researchers are measuring crop wateruse efficiency by yield per drop of water actually taken in by the crop. Crops are being grown with six levels of irrigation, from full irrigation down to only 40 per cent of full. These results will help farmers in this region decide whether to put all their irrigation water into producing corn, or to reduce either their irrigation levels or the amount of land they plant, and sell or lease water rights on the rest. (Source:

The Future of Food: Why Farmers Are Being Driven off the Land Chris Turner, author of The Geography of Hope and The Leap, has written an article in online magazine The Walrus about how “the growing gap between what they produce and what they earn is driving many farmers off the land.” The article, an eye-opening look at how modern farms work, explains how growers have to “get big or get out” and shows how the system is optimized to deliver the maximum yield per hectare at the lowest possible cost per unit of production, guided by a largely undeclared continental food regime sometimes called “the cheap food policy.” In the history of agriculture, Turner claims, no one has ever paid less for their calories than contemporary North Americans do.

Using Ground Covers in Organic Production Recent studies by U.S. Department of Agriculture (USDA) scientists indicate that fabric and polypropylene ground covers used by organic farmers to control weeds did not significantly impede the penetration of nutrients and water into the soil. One study found that soil microbial activity indicators were essentially the same in soils protected by fabric covers, those protected by polypropylene covers and control soil samples where the movement of nutrients had not been impeded by a ground cover, although links were observed between the use of fabric covers and reduced soil levels of nitrogen and phosphorus.

The Future is Up - Greening America’s Rooftops

Our cities are growing rapidly as more of us seek out the urban lifestyle, but have you ever looked down at a city through a plane window and noticed how barren the tops of all those buildings look? Rooftops stretch as far as the eye can see, but most roofs hold little more than HVAC systems and the odd cellphone relay station. With all of our efficient urban planning, we still always seem to overlook this valuable real estate in the sky. For a variety of reasons, though, planners and entrepreneurs are now looking at the potential of these spaces to radically change our cities, and potentially, the future of our food supply. Green roofs are something that many of us have begun to hear about—and more and more often we are now actually able to see them in real-world applications. A green roof is simply an extension of a standard roof, which involves installing a waterproof layer on top of normal roofing materials. This layer is part of

a system that involves a root barrier, a drainage network with growing medium and select plant species. There are two main types of green roofs and they are very different from each other, even though many of the benefits they provide are identical. The first and more common type is an

extensive green roof, which generally involves a modular system forming an interlocking grid. The growing medium is quite shallow and under high temperatures leads to a low-moisture, almost desertlike microclimate. The coarse mineral-based soil lends itself to low plant diversity. The plants have to be low to the ground and hardy in order to survive this harsh environment, so generally alpine, dry land and indigenous species are selected. This type of roof is not very pleasing to the eye—sometimes more brown than green—but it is functional, inexpensive to install and requires very little maintenance. The future probably lies in intensive green roofs, installations where functional aesthetics are the goal. These rooftops feel like real gardens, with ground cover, shrubs and even trees. The relatively deep soil puts a heavy load on the roof and reinforcement is sometimes required, but

along with the high capital cost associated with this type of roof there are also amazing benefits, including the possibility of local urban food production. There are lots of good reasons for planning green roofs into our cities before we even begin to consider local food production, including positive economic, social and even environmental benefits. When it comes to pure economics, there are several reasons to consider installing green roofs. The first bonus is found underneath the garden. When roofs are covered with soil and plants they last for much longer because the sun’s energy is being absorbed by the organic material, so a roof that needed replacing every 10 years might now last 40. Extending the life of roofing materials is an exceptional benefit for developers and could be a key reason for them to consider greening their next project. A green roof also means there is essentially an extra floor on top of every building and from a building owner’s perspective this means additional revenue. This might seem greedy, but always remember the best way to get private sector buy-in for additional costs is increased revenue. For the early adopters there is also a marketing and branding opportunity available here to Photo Credit: Patrick Blanc

promote the green initiative and take advantage of the publicity around its development. Because of the vegetation and growing medium they are covered in, green roofs provide dramatic temperature regulation. This is a key benefit because it helps deal with the urban heat island effect, where hard surfaces absorb heat, thus increasing city temperatures. The green material absorbs solar energy without any massive release of heat and it also actively cools the surrounding air with the evaporation of dew and with water created by the plant’s own transpiration. A planted roof will cool a building in summer and warm it in colder weather, reducing dependence and stress on building ventilation systems and saving energy. This is a clear economic benefit with the increased energy efficiency, but it’s also easy to see how this has social and environmental benefits as well. From a purely social perspective, the aesthetics of rooftop gardens soften hard city lines and the tranquility provided can act as a sort of horticultural therapy for residents. A green roof can provide urban park land by taking advantage of what is essentially wasted space and the foliage can even reduce the amount of noise that echoes through busy urban areas.

can be a much-needed reminder of the natural world outside of our urban sprawl and allow us to feel connected with nature while surrounded by skyscrapers. Gardens within our cities can also be gathering places and can create a stronger sense of community. We are only just coming to realize the serious importance of green spaces to human health and the sense of wellbeing such natural connections provide. As more research comes out showing the tremendous benefits of greening in our urban communities it becomes increasingly clear just how important such initiatives will be for the social fabric of our communities in the future. Part of the problem with industrial agriculture is the lack of diversity in our production systems. Monocrops have no place anywhere—especially on our rooftops—and biodiversity is probably one of the most important benefits green rooftops will provide. Bringing the natural world back into our urban spaces will create a healthier ecosystem as well as a more enjoyable experience for garden managers and people who just enjoy green spaces. The flow of water in a city during a rain or snow event is affected by all the hard surfaces—concrete surfaces that can 54

absorb little to no water. This can put incredible pressure on storm drains and the water system, but the plants and soils of a green roof can retain huge amounts of water. This water is then filtered and used by the plants or released much more slowly into the city’s drainage system. Our cities produce a large volume of carbon emissions, but as green roofs grow they fix atmospheric carbon, which can help to keep our carbon dioxide levels in a more manageable range. Plants absorb carbon along with many other compounds from the air and there are clear benefits when plants are used to purify the air in our communities. Air quality can be a health hazard, but plants are a natural HEPA filter! So our green roofs can provide carbon sinks that clean the air, make people feel better, help the environment and increase profits for developers—and they could even help feed us. Rooftop gardens hold the key to urban food production. There is nothing more local than farming on the top of a building and selling the produce on the street below. Being close to market would be a huge benefit to the many potential urban farm businesses that would develop as a result of rooftop

greening initiatives. These micro-farms would also be labor-intensive, meaning there would be a positive affect on local employment. As with organic farming, the emphasis would be on labor rather than mechanization, which would bring more people back to growing food—an important step considering how many young people are abandoning farms for the city. A reconnection with our food supply would be positive not just for garden workers but also consumers, who would feel much more connected and in tune with their food. There would also be the peace of mind and security that would come from knowing where our food was coming from and that it was produced locally. The movement toward greening our cities is now beginning to get the attention it deserves and green rooftops clearly have a tremendous role to play in the development of the green potential of our urban spaces. Using the skylines of our cities to grow food looks like it will be the way of the future and the benefits will be tremendous. For now, we’ll keep watching the city planners and urban innovators as they continue to search for the best methods to bring food to our rooftops… MY

Understanding Heirloomology

The people have spoken and for the first time in ages the availability of heirloom fruit, vegetables, herbs and flowers is on the rise. Seed-saving banks that distribute heirloom seeds to the home gardener have become more numerous and popular in recent years and many farmers are making the switch to growing heirloom strains, breaking into this new market in order to meet the demands of concerned consumers. By growing a variety of cultivars many farmers are able to reduce the use of expensive pesticides, creating healthier, safer food and cutting operating costs significantly. Some grocers have started to specialize in different organic heirloom alternatives to the standard commercially grown hybrid varieties that have dominated produce sections for so many years. This groundswell of change is the result of a lot of hard work and education—growers and consumers alike have begun to seek a better way and the food industry is beginning to listen. Heirloom or heritage strains are open-pollinated plants that are true, distinct breeding varieties. In modern agriculture, however, commercial farmers grow hybrid monocultures. They generally grow one type of hybrid vegetable that cannot reproduce, obliging farmers to buy seeds from large seed

companies each year. Within a monoculture there is very little genetic diversity, which means that a certain pest or disease could take out the entire crop. This is why farmers must use so much pesticide to protect their crops. For example, the great potato famine was largely the result of a monoculture of potatoes becoming infected with potato blight, leading to the widespread starvation of millions. Heirloom crops, on the other hand, not only provide more variety to the consumer who may be tired of the same pepper varieties season after season, but they also allow farming to be safer. If a pest or disease attacks a farm that grows heirloom crops it might wipe out one strain, but genetic diversity would probably allow the other strains to survive. There are a huge variety of peppers—in every shape, color, size and degree of heat. The first unique heirloom pepper strain we’ll discuss is called the Black Hungarian. This cultivar is a very hearty strain and can handle colder weather than most types, making it an excellent choice for those of us living in cooler climates. Black Hungarian peppers are quite productive and since they are an early type—maturing in about 70 days—they’re a great choice for short growing seasons. Black Hungarian peppers produce fruit similar in shape to a jalapeno, except the fruit starts dark purple (almost black) then turns red as it ripens. The foliage is ornamental, with green leaves and purple veins. In terms of taste and heat, Black Hungarian peppers are known for their great flavor, almost as spicy as a chili pepper but slightly milder in taste, which would

The Scoville scale indicates the level of capsaicin (the chemical that creates the spicy flavor) present in the pepper—as a reference, green peppers are rated at zero SHUs and jalapeno peppers are rated at around 3,000 to 5,000 SHUs. Black Hungarian peppers can be easily cultivated indoors in soil or soilless mixes or in hydroponics. During the vegetative stage you should provide the plant with 18 hours of uninterrupted light, followed by 12 hours of uninterrupted darkness. They will grow to be 18 to 24 inches tall and will produce fruit ranging from four to six inches in length. Black Hungarian peppers do best in full sun with a pH range from 6.1 to 6.5 and they can be forced into blooming by switching the photoperiod to 12 hours of uninterrupted light followed by 12 hours of uninterrupted darkness—although they will often begin to flower on their own.You must self-pollinate these peppers when gardening indoors. To best accomplish this, use a small paintbrush—once your peppers begin to flower, simply

touch the end of the paintbrush inside each flower a couple of times a day, which should ensure the spread of pollen from flower to flower. Another excellent heirloom pepper is the Matchbox pepper, a variety of the Super Chili pepper. Matchbox pepper plants grow 18 to 24 inches in height and produce small, two inch fruit that begins green and turns red as the fruit ripens. The peppers are often eaten when green, but have a little extra sweetness to them once they turn red. Matchbox peppers are quite fiery— they can be as hot as 30,000 SHUs—and while the thick skin found on these peppers allows them to retain their flavor, it does make drying them difficult. Matchbox peppers can be easily cultivated indoors. Peppers germinate best in warm environments, so when starting seeds use a heating mat or place the seeds in a warm place such as the top of a fridge or a sunny windowsill. Just be careful not to overheat the seeds, as they will go dormant if temperatures

get above 95°F. Matchbox peppers have pretty much the same requirements as Black Hungarian peppers, except that they are less tolerant of cooler temperatures and they are not recommended for short outdoor growing seasons as they can take 80 to 90 days to mature. Another type of heirloom pepper—rare, and one of the most unique I have ever come across—is called Grandpa’s Siberian Home Pepper. This type of pepper plant is really small, growing just one to 1.5 feet in height. Grandpa’s Siberian Home Peppers produce small fruit that are just a half inch to an inch in length and are red to purple in color. The heat level of this particular pepper is around 1,500 to 4,000 SHUs, giving it a nice amount of heat while still maintaining good flavor. What makes Grandpa’s Siberian Home Peppers so unique is that this variety was developed in Siberia and was bred to overwinter indoors. They are grown outdoors throughout a short summer season and at the end of the season they are just beginning to mature, which is when you bring the plants indoors— where they will continue to produce fruit all winter long. And the best part is that this variety can thrive on lower levels of light: all you need to successfully overwinter your Grandpa’s Siberian Home Peppers indoors is a sunny windowsill.

Another great type of heirloom pepper is the Chimayo pepper, which originates from the farming town of Chimayo, New Mexico, famous for its chili. Chimayo pepper plants grow to be 18 to 24 inches tall and will produce tapered fruit that is four to six inches long. These peppers begin green and will turn red as they ripen and are said to be one of the most magnificent-tasting peppers available. The heat levels are on the mild side—measuring only 1,000 to 5,000 SHUs—and they are ideal for drying because their flesh and skin is quite thin. The Chimayo pepper, which can be easily cultivated indoors, has a few

characteristics that set it apart from other peppers. It’s an early variety, maturing in 60 to 70 days, and will actually begin to flower when it is still a seedling about four inches tall. This makes the Chimayo pepper a great choice if you are growing them outdoors in a short-season part of the world—and when growing them indoors, it simply means more peppers in less time. The world of heirloom peppers is one of endless possibilities, a world where every pepper has a unique flavor, color and level of heat. Whether you are using peppers for chili, pickling, drying or just adding spice to any of your favorite dishes, it is hard to imagine ever tiring of the never-ending variety of peppers that can be grown in your own home.

Use Less

Water by Dr. J. Benton Jones, Jr.

(and Grow More)

Sub-Irrigation Hydroponics No electricity required The future of hydroponics lies with sub-irrigation techniques for delivering water and nutrient solution. There are huge advantages in the use of water and reagents compared to other hydroponic methods. Sub-irrigation systems provide control of plant root activity, which results in superior vegetative growth and fruit yield.

Use Less Water (and Grow More)

A number of years ago I joined a group of agronomists as we visited several research stations and commercial farms that were using various irrigation methods. One of the more interesting visits was to a research station where cotton was being irrigated by sub-irrigation using a new product called leaky pipe, placed six inches below the soil surface under each cotton row. Nearby fields were being flood irrigated. What was remarkable was that the plants receiving water by means of the leaky pipes were larger and more vigorous in appearance than those receiving water by means of flood irrigation and we were also told that water use was 30 per cent less with the leaky pipe system. However, there were two drawbacks to the system—the leaky pipe had to be replaced each year and control-fitting leaks were difficult to locate and fix.

“The primary advantage of sub-irrigation is that all of the applied water and essential plant nutrient elements pass through the plant with no loss of either to waste and the system can be operated by gravity flow with no need for electrical power.”

In the 1960s, fresh market stake-tomato growers in the Bradenton, Florida area were experiencing financial challenges due to high production costs. Since the Bradenton soils were sandy, replacement fertilization following periods of rainfall was required. In addition, the underlying water table had to be controlled by ditching to keep it below the rooting zone. However, an innovative method for growing tomato plants under such soil conditions was eventually developed, based on the ability to control soil depth in relation to the water table. A soil bench was formed, fertilizer for the crop season was applied on the soil surface and

Figure one: cross section of a plastic sheet covered soil bench for growing tomatoes in a sandy soil, showing the position of applied fertilizer and mulch and the water table creating a moisture gradient zone where roots occupy that portion of the soil where there is a balance among water, plant nutrient elements and air.

Use Less Water (and Grow More)

the bench was then covered with plastic. The water table was adjusted during the growing season in order to keep the soil under the bench moist. The inventor, Geraldson (1963), named this system concept “quality and balance,” since it established a nutrient-moisture gradient within the soil bench. A cross-section of the soil bench (shown in figure one) gives the dimensions and position of the applied fertilizer and the depth of the water table. This system not only saved the stalk-tomato growers’ business by reducing their production costs, but the tomato plants responded to the consistent nutrient element-moisture environment by producing higher yields of market-quality fruit. Using this sub-irrigation principle, several colleagues and I successfully grew greenhouse tomatoes in seven inches of milled composted pinebark placed in a watertight container. The required fertilizer for the season was mixed into the pinebark and an inch of water was maintained in the bottom of the box using a float value mechanism. An article describing this method for use by the home gardener appeared in the March 1980 issue of Popular Science magazine (Jones, 1980) and a research paper was published authored by Bruce et al (1980). The Scaife pipe dream growing method applied the same principle for supplying water and essential plant nutrient elements by means of sub-irrigation. A sock of sphagnum peat moss was

placed into a vertical pipe fitted into an opening in a horizontal pipe of circulating nutrient solution. Scaife attributed the vigorous plant growth he obtained to what he called the carburetor effect—the aeration conditions that existed around the root mass as illustrated in figure two, again a result of the use of sub-irrigation. There are two growing systems marketed today that employ the sub-irrigation technique. In the one growing system, the rooting container is filled with an organic rooting medium containing sufficient essential plant nutrient elements to carry the plants through the growing season. By observing an indicator float, water is added by hand when needed to maintain a certain level in the bottom of the rooting vessel. In the other growing system,

Figure three: on the left are three 9-gallon boxes, two planted with tomatoes and one with peppers (four plants in each box), and on the right are two troughs planted to green beans. The two 30-gallon garbage cans in the back ground are the supply tanks that deliver by gravity nutrient solution to the float values in each of the rooting vessels.

each rooting vessel has its own value that regulates the level of nutrient solution in the base of the pot, the nutrient solution being delivered to the value by gravity flow from a supply tank. I have devised similar growing systems, one using nine gallon plastic storage boxes as the rooting vessel, and the other being constructed troughs that are 13 feet long, four inches wide and seven inches deep. The level of nutrient solution in the base of the rooting boxes and troughs is maintained using an attached float value. Nutrient solution is delivered to the float value by gravity flow from a supply tank. One of my home garden arrangements using boxes and troughs is shown in figure three.


Maximum Yield USA | November 2011

Use Less Water (and Grow More)

The primary advantage of sub-irrigation is that all of the applied water and essential plant nutrient elements pass through the plant, therefore no loss of either to waste and the system can be operated by gravity flow with no need for electrical power. My experience with long troughs has revealed that there exists a water-flow mechanics issue, requiring the placement of a dispensing pipe in the bottom of long (greater than four feet) troughs. By maintaining a constant level of nutrient solution (or water) in the base of the rooting vessel, roots will occupy that portion of the rooting medium where there exists a balance between occupied water and air space. Root absorption of water and plant nutrient elements is controlled by root activity and therefore not influenced by periodic applications of either water or nutrient solution. For use in my growing systems, a dilute nutrient

solution formulation is required. I have found that a 1/3 dilution of a modified Hoagland/Arnon formulation is sufficient to meet the nutrient element needs of most plants with no need to change the formulation based on plant species or stage of growth. One essential requirement is that the level of nutrient solution in the base of the rooting vessel be kept constant, as a changing depth will adversely affect root function. Therefore, automatic depth control is essential for maximum plant performance. Constancy within the rooting vessel contributes to greater vegetative top growth, since the root system is stabilized and not continually growing in size. I have used various rooting media: perlite, composted milled pinebark, a 50/50 mixture of perlite and composted milled


Maximum Yield USA | November 2011

pinebark, as well as various organic soilless mixes, but perlite consistently gives the best results. The depth of the rooting medium is critical, based on its own wicking characteristics. Seven inches of either perlite or composted milled pinebark seems to be the optimum depth, sufficient for maintaining the proper mix of water and air within the medium while keeping the top surface dry. The hydroponic sub-irrigation concept has great potential, currently only lacking innovative growing systems that would lend themselves to wide commercial use. The savings in water and reagents compared to other hydroponic methods in use—such as flood and drain or drip irrigation—would certainly seem to justify more intensive commercial development and use. The other major advantage for the sub-irrigation technique is of course that it requires no electrical power. MY

Killer All-natural neem oil will kill bad bugs dead without harming the good guys With today’s push for more organic gardening in the home garden, it can be hard to balance using natural cures for common problems and still get a good harvest. Some organic pesticides are not as effective as their chemical counterparts, but there is one exception, and that is neem oil. Neem oil not only effectively kills the pests on your plants (without hurting beneficial bugs like bees) but it can also eliminate most fungus problems. If you are wondering what neem is used for and how you can use a neem oil foliar spray in your garden, keep reading.

What is neem used for? A neem oil foliar spray is used in the garden one of two ways—as an insecticide or as a fungicide.

Neem oil as an insecticide Neem oil is an effective insecticide against many insects that can hurt your plants. These include: • Aphids • Mealybugs • Mites • Scale • Japanese beetles • Whiteflies • Any pest that chews or sucks on the plant


Maximum Yield USA | November 2011

Neem oil insecticide doesn’t kill bugs that don’t chew on leaves. All beneficial bugs fall into this category, so you can spray your plants with this organic spray without worrying that you’re harming the good guys, like bees, butterflies and spiders. Neem oil insecticide is unique in that it does not immediately kill the insects it affects. Instead, for reasons not yet understood by scientists, neem oil insecticide causes a pest to be unable to maintain hydration, which in turn kills it. Some pests are also repelled by neem oil insecticide, which means they stay away from the plant that was sprayed with neem oil.

Neem oil as a fungicide Neem oil is also an effective fungicide. Applying it to plants can kill harmful and unsightly funguses such as:

• • • • • •

Powdery mildew Root rot Rust Black spot Sooty mold All other kinds of fungi

Is neem oil safe for humans?

Neem oil is safe for humans and is a common ingredient in things like toothpaste, shampoo and cosmetics. It is found to be safe in smaller amounts for human consumption, and since insecticidal mixtures of neem oil contain only a very dilute amount of the oil, you can eat fruits and vegetables that are treated without any problems. It is commonly used in organic farming.

How to apply neem oil foliar spray

Neem oil is normally applied as a spray to the leaves of the plant. While neem oil is a good insecticide, there are some things to keep in mind when using it. First, some plants can be killed by neem oil, especially if it is applied heavily. Before spraying a whole plant, spray a leaf on the plant and wait 24 hours to see if the leaf has any damage. If there is no damage, than the plant will not be harmed by the neem oil. Second, neem oil should not be applied to a plant in direct sun. If the plant you want to treat is in full sun, apply the neem oil foliar spray in the evening so that it has time to absorb overnight. Also, do not use neem oil in extreme temperatures, either very hot or very cold. Do not apply neem oil to plants that are stressed, either due to drought or overwatering. Apply your neem oil insecticide about once a week to most kill and control pests. Apply neem oil like you would other oil-based sprays— make sure the leaves of the plant are coated, especially where the pest problem is the worst.

Where to buy neem oil Most nurseries and garden centers sell neem oil. Even some of the big box stores are starting to carry this increasingly popular pesticide. MY For more gardening tips and tricks visit or check out

Many of us have experienced the satisfaction that comes from growing our own fruits, vegetables and herbs from an indoor garden and being able to provide something fresh and healthy for family meals. Our furry, finned and feathered friends don’t need to be left out when it comes to the benefits of hydroponic gardening, though—after all, we want our pets to have the best quality, safest and pesticide-free snacks possible too! The range of animals who love to chomp, sniff or nibble certain types of vegetation is quite wide—even carnivores such as cats and dogs often appreciate some fresh greens, although for some it’s only a few blades of grass. Small caged pets such as hamsters, guinea pigs, rabbits, rats and mice can all benefit from having their diet extended with fresh greens, sprouted grains, fruits and vegetables, all of which can be easily grown indoors.

Plants for cats and dogs Both cats and dogs may be attracted to fresh grass and occasionally nibble a few blades. The reason they do this is not really known—vitamin deficiencies, hair balls, feeling unwell or just boredom have all been cited. For whatever reason, it does seem that some animals do crave fresh grass; indoor pets in particular should be offered some access to safe greenery. Outdoor grass may not always be a safe option for pets, as chemicals applied to lawns and grassed areas to control pests might be present and the risk of contamination in some areas can be high. Luckily, grass is relatively easy to grow and performs well indoors in a shallow tray when fed good-quality hydroponic nutrients. Even once nibbled on, grass is highly resilient and will regrow many times without the need for a lot of space. 86

One of the best grass species for cats and dogs is Dactylis glomerata, also known as cat grass or cocksfoot. This is a very hardy, drought-tolerant and vigorous grass species that grows well in containers over a range of temperature conditions. For hydroponic production, a tray should be thickly sown and cut back with scissors if excessive vegetation becomes an issue—the grass will continue to grow and produce fresh produce year round. For trays of cat grass, the safest growing mediums are coco fiber, peat or thick mats of microgreen material, which are least likely to contaminate the grass with indigestible particles. Standard vegetative hydroponic nutrients can be used from germination right throughout the life of the pet grass tray using overhead watering or ebb and flow systems. Most pet owners

who grow their own trays of cat grass tend to have two to three small trays, which can be rotated and offered to pets one at a time while the others remain under lights regenerating foliage. Perhaps the best-known plant grown specifically and on a commercial scale for the pet trade is catnip (Nepeta cataria). Dried catnip and catnip sprays are used in a huge range of cat toys and products, although the fresh plant material can be somewhat more potent and many cats enjoy harvesting their own directly from an indoor garden. It’s estimated about 80 per cent of cats respond to catnip—some with dramatic behavioral changes which many owners find highly entertaining. The compound responsible for this reaction—which only occurs in cats—is nepetalactone, found in the foliage and stems of the plant, which retains its psychoactive powers even when the foliage has been dried and stored for many months. Catnip, being a member of the mint family, is an excellent specimen plant for an indoor garden and performs spectacularly well in hydroponics, with masses of lush vegetative growth followed by small pink or white flowers. The plant is easily grown from seeds that readily germinate within a few days and are highly productive. Catnip is well suited to NFT and aeroponics as well as many container systems and prefers a moisture-retentive medium. The plants are hardy and will continue to grow year round with sufficient warmth and light. As long as the plants are regularly harvested and cut back a compact bush will develop, although growth can spread outward over time and may need some heavier pruning now and then. The only problems with hydroponic catnip plants can be infestation with thrips or mites and the fact that the plants do tend to become very tall and lanky under ‘lower-than-optimal’ light conditions. The aromatic and volatile compounds in catnip—as with most herbs— are concentrated when the nutrient EC is run at moderate Aquarium fish enjoy fresh plant material; hydroponics can be used to propagate and grow tropical and cold water aquatic plants.

to high levels and under bright, direct light conditions. EC in the range of 2.5 to 3.8 will provide a potent catnip product that will delight any nepetalactone-sensitive felines. Hydroponic systems containing catnip plants may need protection from unsupervised pet visits, as cats intoxicated on this herb have been known to do considerable damage to plants. Harvesting a few stems at a time and offering this to pets away from the indoor garden area as well as drying any excess foliage is a good way to manage the plants. Another complimentary and related herb for the cat garden is catmint (Nepeta faassenii), which is a more ornamental form of Nepeta with striking purplish-blue flowers and grey-white foliage. While not as potent as catnip, it does have a mild effect and makes an attractive ornamental plant.

Fish, turtles and reptiles “It’s estimated about 80 per cent of cats respond to catnip—some with dramatic behavioral changes which many owners find highly entertaining.”

light and CO2 is readily available in the system. Many aquarium plants, particularly the tropical species, grow reasonably fast when provided with hydroponic nutrients and temperatures in the range of 68 to 82°F. A deep tank system will provide sufficient room for growth and most plants will require a good depth of growing medium (either aquarium sand or gravel) to anchor the stems during the propagation phase. With most species being easily divided or grown from stem cuttings, which readily form roots, aquatic plants are a great addition to aquarium tanks and as a valuable source of fresh food for fish.

produce. Rabbits and guinea pigs in particular should be offered fresh grass and one of the easiest ways of doing this safely is with sprouted grains such as wheat or barley. Standard grass such as cat grass (Dactylis glomerata) can also be grown for other caged animals, although its rate of growth is much slower than that of sprouted grains, which can be ready for cutting and feeding in less then 14 days. Another plant that can be grown in hydroponic media beds or containers—making a spectacular specimen due to its size—is the mangel, (Beta vulgaris var crassa), which is much loved by rabbits, but also by larger pets such as chickens, sheep, pigs and cattle. The mangel is a type of large beet that produces a large swollen root as well as a mass of edible leaves that are nutritious and highly palatable. Other root vegetables such as carrots and radishes can also be grown in hydroponic media beds and shared with caged pets.

While commercial systems use automated equipment to grow large volumes of fresh fodder for livestock, the same can be done on a smaller scale indoors to grow fresh plant material for many pets. Laying hens and other types of indoor poultry respond well to fresh fodder grasses, as this increases the intensity of the yellow yolk color in eggs as well as giving the hens some valuable vitamins and minerals.

Other pets such as goats, sheep and deer also appreciate fresh hydroponic grass during the depths of winter—when only dry feed may be available—and even a small indoor growing space will produce a good biomass of fresh feed over a relatively short time.

Caged birds Although caged or aviary birds might have a diet dominated by commercial seed mixes, many birds love being given an entire dried flower head of sunflower seeds to pick at and pull apart. There are now many varieties of dwarf sunflower plants that can be grown in containers or indoor gardens that not only look spectacular when in full bloom, but can later be harvested, hung up to dry completely and then fed to caged birds. Millet, another seed crop, can also be grown in this way and the entire plant can then be placed into aviaries for birds to harvest themselves. Many caged birds also enjoy an occasional treat of greens such as sprouted and cut wheatgrass, although not all species will consume these sorts of treats. While growing catnip, sunflower seeds or aquatic plants in an indoor hydroponic garden may not directly benefit your own health, your furry, feathered and finned friends will certainly appreciate your efforts. It’s also a great way to encourage species diversity—both plants and animals flourishing together in your indoor growing space. MY

Lights, Power, Grow Lighting basics

for beginners and hobby growers by GrubbycuP


Maximum Yield USA | November 2011

The kind of light that plants require to grow and flourish is not necessarily the kind of light that we are familiar with— the lightwaves our eyes see best with are not the same lightwaves that plants use. While outdoor plants benefit from true full-spectrum lighting, the indoor grower must supply his crops with the wavelengths they need to thrive. Proper lighting is one of the most important facets to a successful indoor garden and indoor gardeners should understand at least the basics.

Maximum Yield USA | November 2011



Maximum Yield USA | November 2011


Light is energy; a form of electromagnetic radiation made from electric and magnetic fields set at right angles to each other. These fields are synchronized together and collectively are known as an electromagnetic field. Electromagnetic radiation travels in a wave emitted outward from a source.


Although the speed of light is a constant, the wavelength and frequency is not. The speed at which the same point on the wave passes by a point in space is the frequency.

Approximate values by color: Red: 625 to 700 nanometers Orange: 600 to 624 nanometers Yellow: 599 to 670 nanometers Green: 500 to 569 nanometers Blue: 465 to 499 nanometers Indigo: 426 to 464 nanometers Violet: 400 to 425 nanometers

Maximum Yield USA | November 2011


Lights, Power, Grow

“Although the speed of light is a constant, the wavelength and frequency is not. “

The distance between wave crests is its wavelength—a wavelength is literally the length of the wave. Even though specific numbers are often used as boundary markers, electromagnetic waves are actually not this precise. Where one color starts being a different color is more an approximation than a hard line. The order of longest to shortest wavelengths is: radio waves, infrared (heat), visible light, ultraviolet, X-rays and gamma rays. The human eye uses only a small portion of the electromagnetic spectrum to see with, the wavelength of visible light between about 390 and 790 nanometers. This visible light is further broken down into colors—the long wavelength end of the visible light spectrum is perceived as red and at the short end of the spectrum is violet. Lightwaves slightly too long to be red are called infrared, while wavelengths slightly too short to be violet are called ultraviolet. Objects appear to be the color of the light they reflect. If all colors are absorbed by a leaf except for green, then the leaf will appear green. The wavelength of the electromagnetic field determines its color if visible, or its type if not. Photosynthesis in plants makes the best use of light with wavelengths from peaks at the red, blue and violet bands. Chlorophyll ‘A’ is the blue-green pigment in plants and two peaks of absorption occur at 665 (red) nanometers and 465 (violet-indigo) nanometers. Chlorophyll ‘B’ is the yellow-green pigment in plants and absorbs light at two peaks of 640 (red) nanometers and 450 (indigo-blue) nanometers. The colors in the valley between the two spikes, between 500 and 600 nanometers (the green and green-yellow bands) are not used as much and are mostly reflected by the plant, which is why most plants have green foliage. An ideal light source should supply wavelengths including 640 to 665 nanometers (red) and 450 to 465 nanometers (indigo). A rule of thumb is that cool lights lean toward the blue-violet side, while warm lights tend toward the red-orange side.


Waves not only have length, but also height or amplitude. The greater the amplitude, the more energy it contains and the brighter the light. A light at 550 nanometers will appear green— either dim at low intensity or bright at a high intensity—but the color will remain the same. The greater the intensity, the more energy is transmitted. A lumen is the light of one candle. A lux is that light from one meter away, spread over a square area three feet wide. A full moon on a clear night lights at about one lux, a well-lit indoor room is about 400 lux and bright sunlight is about 100,000 lux.

Lighting efficiency


Maximum Yield USA | November 2011

Power comes from a source—such as a wall plug—and goes through a process to give off light. How much of this power is converted to useful light is known as the lighting efficiency. If the process produces 683 lumens of light per watt of energy used, perfect efficiency has been achieved. Fire gives off light, but most of the energy is expressed in the infrared wavelengths and therefore is not very well suited for growing plants. Incandescent lighting has an efficiency of about six per cent (10 to 30 lumens per watt). LEDs are also about six per cent—although in theory they could be made more efficient—fluorescents are about 10 per cent (30 to 100 lumens per watt), metal halides 14 per cent (70 to 125 lumens per watt) and high-pressure sodiums clock in at five per cent (60 to 140 lumens per watt). The excess heat generated by lighting systems is often the largest source of waste heat in a garden.

“...make sure you can deal with any waste heat your lights generate, as cooked plants perform even worse than under-lit ones do!”

Light levels drop exponentially over distance. An object twice as far away will receive only ¼ of the light since the light is spread out over four times the area.

Matching the light to the space

One number that is often listed represents lumens— which includes all the light given off by a source (including the lesser used wavelengths)—but at least it is an estimate to work with. The amount of light that ends up actually hitting your plants drops off as an inverse square to the distance. At 6.5 feet, the lux is reduced to ¼ and at 10 feet it is reduced to 1/₉th. A plant that is twice as far from the light source only receives ¼ of the light, while a plant three times as far only receives 1/₉th. If a 400 watt bulb gives off 50,000 lumens in an area three feet to a side, then the bulb gives off 50,000 lux. These lights are used for areas 1.6 feet to three feet to a side. This same bulb could be used to light an area 6.5 feet on a side, but it would deliver only 12,500 lux to the plants. A 600 watt bulb giving off 95,000 lumens at three feet—a bulb size well suited for three feet to four feet gardens—still delivers only 23,750 lux at 6.5 feet. A 1,000 watt bulb may give off 130,000 lux, which would be overkill for three feet, but 32,500 lux over a 6.5 feet space is more reasonable. These bulbs are also well suited for gardens of five feet to a side. Measure your grow space and you’ll be able to draw out different scenarios until you find one you like. For example, in a space measuring five feet 10 feet, two 1,000 watt lights, two or three 600 watt lights or three 400 watt lights could be used as a general guideline. However, make sure you can deal with any waste heat your lights generate, as cooked plants perform even worse than under-lit ones do! There are many factors involved in choosing the perfect lighting system for an indoor garden—the better informed you are, the better the chances are you’ll be happy with the results. MY

As summer winds down and we head into harvest time, indoor gardeners become very busy preparing our grow rooms for winter—otherwise known as our prime indoor growing season. Now is the time to add more lights and expand our growing space. Those unfortunate growers who have suffered from excessive heat all summer long are only able to turn lights back on now after they’ve been off all summer—heat from the summer

Cooler weather allows for enhanced environmental control. In residential grow rooms, adding heat is a lot easier than trying to subtract it, especially during those peak summer heat waves that make it nearly impossible to generate a successful crop without the aid of tons of A/C. By the time you’ve put in your second year indoors, though, you should have learned a few lessons. Obviously the fluctuation in temperature from winter to spring to summer can tend to throw off many first-time growers who may have pulled a ‘beginner’s luck’ crop off earlier that winter season.

vegetative grow rooms. Kick off the beginning of the colder season with a healthy veg crop just waiting to transition over into its flowering cycle, because time is valuable and you should make the most of the indoor season. The goal is to achieve more successful flowering cycles during this time since it’s much easier to control environmental problems; in other words, there is less heat and there are fewer bugs during winter.You should concentrate on having a great starter crop for flowering by the time colder temperatures are becoming more frequent. As opposed to trying to band-aid a lost-cause flowering crop suffering from mite damage and heat stress, build the health and vigor of a healthy veg room up a month or so prior to the cold season, so that when the cooler season has arrived you have an immaculate stress-free crop of stock plants, mature vegetatives and cuttings ready to go all season long. Non-air-cooled horticultural lighting reflectors are ideal in the winter grow room so long as the emitted heat does not affect room comfort. In places like the foothills and deep into the mountains, where long periods of near- or below-freezing temperatures are more common, growers may be inclined to use these types of hoods. One major benefit is a stronger penetration of light to the crop due to the fact that no loss is experienced from glass lenses or duct ports on the reflectors. Actual surface area square footage of plant production may increase and the crop may receive higher radiant levels of useable light when

“you can recycle grow light heat back into the house in order to reduce natural gas costs from furnaces or added electrical costs from space heaters.” these reflectors are employed, as compared to air-cooled alternatives. If non-air-cooled reflectors are not an option, use only what is needed in order to keep air-cooled lights cool to the touch. In colder regions, grow rooms operating on a PM to AM schedule will have the least amount of radiant heat hindering production. Because the room will operate and function its ‘ON’ cycle during the coolest parts of the day, there will obviously be less ambient heat at night to combat in conjunction with grow room appliances—such as lights, CO2 generators and so on. Below-freezing air used to cool off air-cooled reflectors housing high-wattage HID lamps may cause condensation to occur on duct runs, walls, and equipment. Either temper the air in a separate space indoors prior to allowing it to enter the reflector housing, or operate the fans on rheostats or fan-speed temperature controllers to facilitate less energy consumption and prevent uncomfortably cool temperatures.

filter all fresh-air intake points, as plant pests and other nasty organisms will be looking to vacation in the HID oasis you’ve created. Water-chilled systems are another great example of new age grow room technology currently sparking the interest of avid indoor farmers intending to keep production consistent year-round. Cloning systems that once suffered failure from pumps overheating reservoir solutions are easily kept to a specific chilled temperature dictated automatically by portable and weatherproof water-chilling units. Although water chillers may seem like a luxury, you can save energy by operating them in the winter since colder air is more readily available. If you’re running a chiller to improve the condition of your nutrient solution, you’re probably already using an air pump to provide enhanced oxygen levels to the root—and if not, it may help. Place the air pump in a cold closet, crawl space or garage if possible and run the air line to the air stone or diffuser. Avoid lengthy air lines, as this may decrease the overall pump output. Low water temperatures may also decrease oxygen availability to the root system, so don’t get overzealous with temperatures below 65°F or suffocation could result. Reservoir heaters (I prefer titanium) combine plug-and-go versatility with a low electrical draw and many integrate a digital LCD for precise temperature control and to prevent overheating. Keep the reservoir at a solid 68 to 70 °F for optimal root health and nutrient uptake and to ensure that concentrations of dissolved oxygen are available to your plants. Winter is a great time for indoor gardening. Seasonal crops that may have been difficult to source for consumers during the winter months because they were field or greenhouse grown can be produced indoors on a perpetual cycle and you’ll be able to charge top-market price for these out-of-season rarities. Fresh yellowstriped boar tomatoes, delicate squash blossoms, ghost peppers and more can now all be harvested in December or January due to the research that has been done and the technological innovations that have resulted in the last few years in the world of indoor horticulture. I urge everyone who is passionate about indoor high-tech gardening to try to enlighten an interested friend or family member. Seeds, dirt and a fluorescent bulb are all it takes to start the beginning of a wonderful addiction—and the more minds we have working together to promote our industry, the more innovation will continue to thrive in the world of hydroponic, organic and year-round gardening.

Cutting With Precision and Ease

by Karen Wilkinson

How to properly take babies from your MILC Cloning your MILC (mother I’d like to clone) is a fairly simple process; however, if done sloppily, in haste or without some experience, it can result in weak, disease-prone offspring. If taken with care and patience, the cuttings will grow into mature, healthy plants. When propagating in an aeroponic cloning machine, the stems will be in their own little environmental heaven, constantly receiving water and air, but virtually no light. So you want to prepare them by caring for your motherplant—you are, after all, making replicas of her genetics, so you want the best. Once you’re ready to take cuttings—given the MILC is at least two months old and in optimal health—get your very sterile tools, rooting gel and system ready (or whatever medium you’ve chosen to produce the clones). But first, a few quick tips: >>

114 114

Maximum Yield Yield USA | November USA | November 2011 2011 Maximum

• Three to four days before taking cuttings, heavily water your MILC to help remove nitrogen (just pH-adjusted water without fertilizers or other additives). By decreasing the nitrogen in the motherplant, you help her babies root faster. • Choose a sharp, clean, thin-bladed knife, razor or pair of scissors to cut the stems. Using dull, blunt tools increases the potential for damaging the plant tissue during cuttings, and therefore increases the risk of disease. • If taking cuttings from more than one MILC, sterilize the blade or scissors between plants to decrease any potential cross contamination (disease, fungus or viruses).

When ready, choose a stem with at least one leaf node that’s about two to four inches long, and relatively new (at least from the current season). Cut about one inch beneath the node. Some people swear by the 45° angle rule, while others say it doesn’t matter as long as the cut is clean; whatever works best for you. Remove any excessive, large leaves off but don’t clip all of them. Leave some, and if needed, cut leaves in half that may take energy away from root growth.

Immediately after taking the cutting, dip the stem in rooting gel. Take extra precautions to pour the gel into a separate container; never dip directly into the rooting gel container as they may cause cross contamination. Though some swear by the 60 second rule, the length of time the stem stays in the gel is inconsequential—as long as it gets some, you’re good to go. When placing the cutting into the growing medium, make sure at least one inch of the stem is below the surface. Once you’re done taking cuttings and they are properly inserted into your unit, be sure to promptly plug in your machine to begin the process. Be clean, be thorough, be patient and above all, be kind to your motherplant—she’s the provider in this equation and will only produce what she already embodies. Happy cloning! MY

Getting Back to Your Roots The Development of Healthy Roots in Soil

Repairing your roots is as easy as 1 (dissect), 2 (wash), 3 (examine).

Sometimes gardeners find that the top foliar growth of their plants is poorly developed and lacking in vigor. Do we understand why this occurs? Perhaps the culprit is a poorly developed root system. To ascertain what the problem that caused the poor growth was, the roots need to be carefully examined after the plant has been harvested. As well as being attentive gardeners, sometimes growers need to be scientists too! In this article we’ll harvest a plant in order to investigate and document what is going on at the root level. At first when we dissect the root ball (image one) it may look as though the roots are thin and mostly located at the edge. Our second task is to wash away the soil from around the roots to see what we really have—this is where we can learn a lot. In image two we can see after the initial washing that the roots look more substantial than they first appeared. Finally, after washing off the top dirt as well as much of the lower root growth we see a well developed, deep and extended root mass. You’ll notice that the better developed the roots are, the more difficult it is to wash the dirt out. What are some of the things that impact root growth?

Soil type also has a major impact on root development, as do macro and micronutrients—and these issues will be covered in future articles. Maintaining the optimum moisture content of your garden soil is like keeping a proper level in your gas tank.You don’t want to be running on empty, but you don’t want to be stopping at every filling station either. During the root development phase it is very important to find just the right balance for moisture. A quality moisture meter can help. Just touching the surface doesn’t give much information—you’ll want to sample surface moisture as well as sub-surface and deep soil moisture in order to have a grasp on the water-holding properties of your soil and to accurately gauge plant transpiration as well as evaporation rates. A slow and evenly dispersed application of water—like rainfall—affords excellent distribution of moisture throughout the entire structure of the soil. If portions of the soil are inadequately moistened they will dry out early and these will naturally be the areas with fewer roots present. It’s difficult and time-consuming to water like this by hand, but fortunately the industry has been developing automated outdoor drip-irrigation systems for many years and now there are some good options for indoor drip systems too. The most significant point here is for the indoor grower to recognize and understand the root development phase of their young plants and to provide the right type of watering, nutrients and soil to encourage them to thrive. When the root system has pretty much expanded throughout the container, then an adjustment to the watering schedule is appropriate. Making this judgment is no easy matter since we can’t see the roots at this stage, but this goes back to examining the root structures of your plants after harvest. Observe and record everything—like a scientist—at every step of your crop’s growth and your notes will be an invaluable reference tool for you to consult for years to com MY Maximum Yield USA | November 2011



Propagation for Profit: Grow Aloe for Dough... Industry veteran Casey Jones Fraser divulges effective techniques and best practices to grow aloe vera for profit. by Casey Jones Fraser

Handle with care!

If you are into houseplants, chances are pretty good that you have an aloe plant in your home. Some gardeners keep aloe around to soothe sunburns or digestive ailments (always consult a physician), but I grow aloe for profit. Sure, I like to have it in my home and I will use it medicinally when necessary, but mainly I grow aloe to sell the small young plants.

........... “...leaf cuttings will not work for aloe, so don’t bother cutting a succulent aloe leaf and shoving it into some soil-even with rooting hormone, it won’t work.”


When you grow aloe under the proper conditions (quality grow lights, extreme periods of drought, plenty of welldraining growing medium) it can grow to quite a large size—my biggest aloe plant is about four feet tall, not including the root ball. Once they start growing at a steady pace, they will also generate small plants that pop up from the root system. Gardeners seeking additional aloe plants can easily propagate these ‘pups’, as they are called. The key to getting a big crop of young aloe plants is growing large mother aloe plants. The large plants produce the small pups from their root systems, so the bigger the motherplant the more pups will appear in your planter.

Grow your motherplants in large containers. Aloe plants will get bigger in every direction if they have enough growing medium, so five gallons or more is ideal for encouraging chunky leaf growth and lots of pups. The fat leaves on these large plants are great for producing homemade ointments or hair treatments. If you are interested in taking aloe internally make sure to first consult with your health professional, as aloe sap can have negative effects on some people when ingested. If you do plan to ingest aloe for health reasons you will need to increase your plant numbers so you’ll be able to harvest the leaves on a regular basis. I propagate these plants because they sell for between $5 and $15 dollars apiece and I sell over 100 of them every year. Do the math—it’s worth it! So what is the best way to propagate the small aloe plants produced by the large mothers? I’m glad you asked! First, however, I’d like to begin by mentioning two ways that I do not recommend. First off, leaf cuttings will not work for aloe, so don’t bother cutting a succulent aloe leaf and shoving it into some soil—even with rooting hormone, it won’t work. Wait for pups to emerge from the soil of larger plants and gently pull them up, roots included. Second, after you have uprooted your baby aloe, don’t put it in a glass of water! I know that many houseplants No gloves, no shovels.

are started in glasses of water, but aloe is native to desert regions and would never experience a glass of water in its natural environment. Author’s note to Grandma Jones: I know you start your aloe pups in water and that it works, but I promise you that my method works better! I’m sorry for contradicting you, and I’ll see you at Christmas. The best way to get aloe going is with tough love. Let the young plants sit out in a tray—no water, no nutrients, no soil. The aloe plants will start to brown off after a few days, but

........... “The best way to get aloe going is with tough love. Let the young plants sit out in a tray - no water, no nutrients, no soil.”

........... be patient. Think of the harsh desert climate of North Africa, where moisture is a precious commodity—aloe has evolved to store water and tolerate drought. After about two weeks, the plants will be greenish-brown and the roots completely dry. Only now should you transplant them into containers. Potting soil is an option and you can even find bags of soil specifically formulated for aloe and cacti, but after years of experimenting with various mixes I’ve found that aloe plants grow best in plain old coconut coir. Coir is the groundup fibers from coconut shells—if you aren’t familiar with this amazing stuff, ask your local hydroponics dealer. The coconut coir will hold plenty of moisture when you initially wet it down. A 20 minute soak is recommended before potting up your new plants. After that, stand your aloe plant up in a six inch pot and carefully fill in around the tap root with wet coconut coir. Gently pack in the loose coir so the aloe stays

in place and then repeat this process until all of the pups are planted. Don’t water your new plants for at least a month. Always wait until the coir or soil is completely dried out before watering again, as overwatering an aloe plant can quickly lead to a type of black spot fungus, which is both unsightly and unhealthy. As far as nutrients are concerned, aloe plants grow well when fed quality hydroponic nutrients along with B vitamins and beneficial microbiology. Once your aloe plants are growing, continue to give them periods of extreme drought, followed by a heavy watering with this nutrient regimen. Feed young plants a very mild solution, but the large motherplants can handle moderate to heavy doses of plant food. So start growing some aloe plants for health reasons or for profit. They thrive when neglected, so plant ‘em and forget ‘em. All you have to do is make sure they have large enough containers and plenty of light; before you know it tiny new plants will be poking through the coir, reaching for the light. And after a few months you might be pulling 30 pups out in one sitting—and that can equate to big bucks at farmers’ markets or in the online classifieds. Supplies for removing pups from motherplants: • Large plastic tray for the mother • Small plastic tray for the pups • Coconut coir to fill in the holes left from removing the pups • Your fingertips and a gentle touch* Supplies for transplanting aloe pups: • A tray full of dry aloe pups • A few six inch containers (clay or plastic) • Coconut coir or loose potting mix • Your fingertips and a gentle touch* *Never use a shovel when digging up the pups. Fragile roots are easily damaged.

Growing for Health

Outside In Bringing what’s outside indoors is simple, if you know how Many gardeners move their houseplants outside in the summer so that the plants can enjoy the sun and outdoor air. But, because most houseplants are actually tropical, they must be brought inside once the weather turns cold.


Maximum Yield USA | November 2011

Bringing plants inside for winter is not as easy as simply moving their pots from one place to another. There are a few precautions you need to take when acclimatizing plants indoor to prevent sending your plant into shock. Let’s look at how it’s done.

Before bringing plants inside for winter… One of the most common issues that arise when houseplants are brought indoors is they bring unwanted pests with them. Check your houseplants thoroughly for small insects like aphids, mealybugs and spidermites, and remove them. These pests can hitch a ride on the plants you bring in for the winter and infest all of your houseplants. You may even want to hose off your houseplants before bringing them in. This will help knock off any pests that you may have missed. If the plant grew over during the summer, you may want to consider either pruning or repotting the houseplant. Do not prune back more than ⅓ of the plant. Also, make sure that you root prune an equal amount off the roots as you do off the foliage. If you will be repotting, use a container that is at least two inches larger than the current container. Acclimatizing plants indoors Once the temperatures outside reach 50°F or less at night your houseplants must come back into the house. Most houseplants cannot stand temps below 45°F. Acclimatizing plants indoors for winter is easy, but without following the tips outlined, your plants may experience shock, wilting and leaf loss. Light and humidity outside versus inside are dramatically different. When acclimatizing your houseplants, start by bringing them in at night. For the first few days, bring the container inside in the evening and move it back outside in the morning. Gradually, over the course of two weeks, increase the amount of time the plant spends indoors until it is indoors full time. Remember, plants that are indoors will not need as much water as plants that are outdoors, so only water when the soil is dry to the touch.You may also want to consider cleaning your windows to help maximize the amount of sunlight your plants get through the windows.

Plants use inorganic minerals for nutrition, whether grown in the field or in a container. Complex interactions involving weathering of rocks, decaying organic matter, animals and microbes take place to form inorganic minerals in soil. Roots absorb mineral nutrients as ions, dissolved in soil water. Many factors influence nutrient uptake for plants. Ions can be readily available to roots or could be tied up by other elements or the soil itself. Soil that is too high in pH (alka132

Maximum Yield USA | November 2011

line) or too low in pH (acidic) makes many minerals unavailable to plants. Fertility or Nutrition The term fertility refers to the inherent capacity of a soil to supply nutrients to plants in adequate amounts and in suitable proportions. The term nutrition refers to the interrelated steps by which a living organism assimilates food and uses it for growth and replacement of tissue.

what is plant nutrition?

Previously, plant growth was thought of in terms of soil fertility or how much fertilizer should be added to the soil to increase the levels of mineral elements. Most fertilizers were formulated to account for deficiencies of mineral elements in the soil. The use of soilless mixes and increased research in nutrient cultures and hydroponics as well as advances in plant tissue analysis has led to a broader understanding of plant nutrition. Plant nutrition is a term that takes into account the interrelationships of mineral elements in the soil or growing medium as well as their role in plant growth. These interrelationships involve a complex balance of mineral elements, which are essential or beneficial for optimum plant growth. Essential versus Beneficial Arnon and Stout proposed a definition of an essential mineral element (or mineral nutrient) in 1939. They concluded that three criteria must be met for an element to be considered essential. These criteria are: 1. A plant must be unable to complete its lifecycle in the absence of the mineral element. 2. The function of the element must not be replaceable by another mineral element. 3. The element must be directly involved in plant metabolism. These criteria are important guidelines for plant nutrition but ignore beneficial mineral elements. Beneficial elements are those that can compensate for toxic effects of other elements and replace mineral nutrients in some other less specific function such as the maintenance of osmotic pressure or provide other nonessential benefits. The omission of beneficial nutrients in commercial production could mean that plants are not being grown to their optimum genetic potential but are merely produced at a subsistence level. 134

Maximum Yield USA | November 2011

In other words, Arnon and Stout’s proposed definition of an essential element is a narrow one. A plant cannot survive without these elements. A better definition of an essential mineral element would include all elements essential for optimum growth and health of any plant. This discussion of plant nutrition includes both the essential and beneficial mineral elements. What Mineral Elements Do Plants Need There are 20 mineral elements essential for plant growth. Carbon (C), hydrogen (H) and oxygen (O) are supplied by air and water. The six macronutrients: nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sulphur (S) are required by plants in large amounts. The rest of the elements are micronutrients and are only required in trace amounts. Essential trace elements include boron (B), chlorine (Cl), copper (Cu), iron (Fe), manganese (Mn), sodium (Na), zinc (Zn), molybdenum (Mo), nickel (Ni), silicon (Si) and cobalt (Co). Note that silicon and cobalt are not considered essential by the Arnon and Stout definition to all plants but are essential to some. Studies have also shown that other mineral elements are beneficial to the growth of some plants. The distinction between beneficial and essential is often difficult in the case of some trace elements. Cobalt for instance is essential for nitrogen fixation in legumes. It may also inhibit ethylene formation and extend the life of cut roses. Silicon, deposited in cell walls, has been found to improve heat and drought tolerance and increase resistance to insects and fungal infections. Silicon, acting as a beneficial element, can help compensate for toxic levels of manganese, iron, phosphorus and aluminium as well as zinc deficiency. A more holistic approach to plant nutrition would not be limited to nutrients essential to survival but would include mineral elements at levels beneficial for optimum growth. With developments in analytical chemistry and the ability to eliminate

contaminants in nutrient cultures, the list of essential elements may well increase in the future. For example, nickel, the most recent addition to the list of essential elements, was added in the early 1990s as a result of several years of research. The Mineral Elements in Plant Production The use of soil for greenhouse production before the 1960s was common. Today few growers still use soil in their mixes. The bulk of production is in soilless mixes. Soilless mixes must provide support, aeration, nutrient and moisture retention just as soils do, but the addition of fertilizers or nutrients are different. Many soilless mixes have calcium, magnesium, phosphorus, sulphur, nitrogen, potassium and some micronutrients incorporated as a pre-plant fertilizer. Nitrogen and potassium still must be applied to the crop during production. Difficulty in blending a homogeneous mix using pre-plant fertilizers may often result in uneven crops and possible toxic or deficient levels of nutrients. Soilless mixes that require the addition of micro and macronutrients applied as liquid throughout the growth of the crop actually give the grower more control of his crop. To achieve optimum production, the grower can adjust nutrient levels to compensate for other environmental factors during the growing season. The uptake of mineral ions is dependent on a number of factors in addition to weather conditions. These include the cation exchange capacity or CEC and the pH of the growing medium and water supply, as well as the total alkalinity of the irrigation water. CEC or Cation Exchange Capacity CEC refers to the ability of the growing medium to hold exchangeable mineral elements within its structure. These cations include ammonium (nitrogen), potassium, calcium, magnesium, iron,

manganese, zinc and copper. Peat moss, coir and mixes containing bark, sawdust and other organic materials all have some level of cation exchange capacity. pH: What Does it Mean? The term pH refers to the alkalinity or acidity of a growing medium water solution. This solution consists of mineral elements dissolved in ionic form in water. The reaction of this solution whether it is acid, neutral or alkaline will have a marked effect on the availability of mineral elements to plant roots. When there is a greater amount of hydrogen (H+) ions the solution will be acidic (pH<7.0). If there are more hydroxyl (-OH) ions, the solution will be alkaline (pH>7.0). A balance of hydrogen and hydroxyl ions results in a pH neutral soil (pH=7.0). The optimum pH range for most crops is 5.5 to 6.2 or slightly acidic. This creates the greatest average availability of all essential plant nutrients. Different mineral elements are available at different pH levels. Extreme variations in pH can cause mineral deficiencies or toxicity by binding or releasing large amounts of various elements. Enzymes: The Workhorses of Life Enzymes are proteins, which are involved in increasing the rate and efficiency of biochemical reactions. Most enzymes require metal ions for activation and function. Without proper enzyme function, growth would cease in an organism. Most of the essential mineral elements affect enzymes in multiple ways. Many of the roles of mineral elements in enzymes are discussed in the following paragraphs. 136

The Elements of Complete Plant Nutrition The following is a brief summary of the role of essential and beneficial mineral nutrients crucial to plant growth. If any one of the essential elements is eliminated from a plantâ&#x20AC;&#x2122;s nutrition, it will display abnormalities of growth, symptoms of deficiency and may not reproduce normally. Essential Macronutrients Nitrogen is a major component of proteins, hormones, chlorophyll, vitamins and nucleic acids. Nitrogen metabolism is a major factor in stem and leaf growth (vegetative growth). Excessive nitrogen can be detrimental to growth by delaying flowering and fruiting. Deficiencies can reduce yields, cause yellowing of the leaves and stunt growth. Phosphorus is necessary for seed germination, photosynthesis, protein


Maximum Yield USAâ&#x20AC;&#x201A;|â&#x20AC;&#x201A;November 2011

synthesis and almost all aspects of growth and metabolism in plants. Phosphorus is a component of RNA and DNA, the genetic makeup of life. It is essential for flower and fruit formation. Low pH (<4) results in phosphate being chemically locked up in organic soils. Deficiency symptoms include stunted growth, reduced yields of fruit and flowers and premature drop of fruit and flowers. Purple coloring may also appear due to anthocyanin and accumulation. Large applications of phosphorus without adequate levels of zinc can cause a zinc deficiency. Potassium is an activator of many enzymes that are required in photosynthesis and respiration. It is involved in osmotic potential in cells. Potassium is also required for sugars, carbohydrates, cell division, protein synthesis and phloem transport. It helps adjust water balance, improves stem rigidity and cold hardi-

ness, enhances flavor and color in fruit and vegetable crops, increases oil content and is important in leafy crops. Deficiencies result in low yields, mottled, spotted or curled leaves and a scorched or burned look to leaves. Sulfur is a structural component of amino acids, enzymes, proteins and vitamins. Sulfur is essential in respiration and lipid metabolism. It imparts flavor to many vegetables. Deficiency symptoms appear as chlorosis throughout the leaves. Sulfur is readily lost by leaching from soils and should be applied with a nutrient formula. Many water supplies contain sulfur. Magnesium is a critical structural component of the chlorophyll molecule and is necessary for functioning or activation of plant enzymes to produce carbohydrates, sugars, proteins and fats.

Maximum Yield USAâ&#x20AC;&#x201A; | November 2011

It is used for fruit and nut formation and is essential for germination of seeds. In essence, magnesium is essential to every metabolic pathway in plants. Deficient plants appear chlorotic meaning they show yellowing between the veins of older leaves and the leaves may droop. Magnesium is leached by watering and must be supplied when feeding. It can be applied as a foliar spray to correct deficiencies.

Calcium activates enzymes, is a structural component of cell walls, influences water movement in cells and is necessary for cell growth and division. Calcium is required for membrane function in all cells. Some plants must have calcium to take up nitrogen and other minerals. Calcium is easily leached. Calcium, once deposited in plant tissue, is immobile (non-translocatable). Accordingly, a constant supply of calcium is essential for growth. Deficiency causes stunting of new growth in stems, flowers and roots. Symptoms range from distorted new growth to black spots on leaves and fruit. Essential Micronutrients Iron is a component of many structural and enzymatic proteins. It is essential for electron transport and chlorophyll biosynthesis. It is, therefore, required for photosynthesis and respiration. Iron is also essential for lipid metabolism. A well-known symptom of iron deficiency is interveinal chlorosis. High soil pH can cause iron deficiency. Toxic levels of iron are associated with waterlogged soils as iron is immobile. Manganese activates many enzymes, but to date, only two are considered manganese-containing enzymes. One of these enzymes is directly involved with the photosynthetic evolution of oxygen. Manganese is required for respiration and carbohydrate and lipid metabolism.

“Copper is an integral component of several enzymes and other critical biological proteins.”

Deficiency symptoms in dicots appear as chlorosis between the veins (interveinal) of young leaves, as manganese is not mobile in plants. In grasses, greenish gray spots on the more basal leaves are a sign of manganese deficiency. In neutral or alkaline soils, plants often show deficiency symptoms. In highly acidic soils, manganese may be available in toxic levels.

IAA synthesis, membrane integrity and carbohydrate metabolism. Deficiency symptoms in dictos include shortened internodes and a reduction in leaf size. Chlorosis often accompanies these symptoms. At low soil pH, zinc may accumulate to toxic levels. Raising the pH is the most effective method of reducing zinc availability in soils.

Zinc is a structural component of many enzymes and also acts as a cofactor in others. Zinc is essential to DNA replication, gene expression, protein synthesis,

Copper is an integral component of several enzymes and other critical biological proteins. It is required in photosynthesis, respiration and lignin biosynthesis and in carbohydrate, nitrogen and lipid metabolism. Copper is also required for pollen grain formation. A copper deficiency can cause die back of the shoot tips, stunted growth and terminal leaves may develop black necrotic spots. Copper deficiency affects fruit and seed formation much more drastically than vegetative growth. Copper is bound tightly to organic matter and deficiencies may result in highly organic soils even though copper is present. Copper becomes toxic to plants at high levels. Molybdenum is a structural component of the enzyme nitrate reductase that reduces nitrates to ammonia.This enzyme is found in all higher plants. Many plants (i.e., legumes) reduce atmospheric nitrogen to ammonia via bacteria located in root nodules.These bacteria use the enzyme nitrogenase, which also contains molybdenum.Without adequate levels of molybdenum, the synthesis of proteins is blocked, plant growth ceases and seeds may not form completely. Not surprisingly, other biologically important enzymes beside the two mentioned contain molybdenum. One of the most common signs of molybdenum deficiency is interveinal chlorosis of young leaves. Other symptoms include stunted seedling growth and those symptoms associated with nitrogen deficiency, including rolled or cupped leaf margins.

Chlorine is involved in osmoregulation, the regulation of movement of water and other solutes into and out of cells. Chlorine is essential for cell division in leaves and in the regulation of opening and closing of stomata. Chlorine is also involved in the photosynthetic evolution of oxygen and nitrogen metabolism. Deficiency symptoms include wilting of leaves, chlorosis and stunted root growth. High levels of chlorine can be severely detrimental to plant growth. Nickel has recently been determined to be an essential trace element for plants by a group of scientists at the USDA Agricultural Research Service (ARS) in Ithaca, New York. It is required for the enzyme urease, which most plants use to break down urea into usable forms of nitrogen. Nickel is also a necessary component for the function of other enzymes. Nickel is essential for iron absorption. Seeds require nickel in order to germinate. Plants grown without an adequate supply of nickel will gradually reach a deficient level at about the time they mature and begin reproductive growth. Boron plays an essential role in membrane integrity, calcium uptake, root elongation, nucleic acid metabolism, cell wall synthesis and pollen tube formation. Boron affects at least 16 functions in plants. These functions include flowering, pollen germination, fruiting, cell division, water relationships and the movement of hormones. Boron is non-translocatable and, therefore, must be available throughout the life of the plant. Its uptake is closely related to the soil pH. It becomes more readily available as pH increases. Deficiency symptoms include discoloration or death of young leaves and terminal bud leaving a rosette effect on the plant. Plants will also fail to set seed and fruit. Leaves are thick, curled and brittle. Fruits, tubers and roots are discolored, cracked and flecked with brown spots. Beneficial Micronutrients Sodium is involved in osmotic (water movement) and ionic balance and is required for some plants. Sodium is essential for many but not all C4 plants. Cobalt is required for nitrogen fixation in legumes and in root nodules of non-legumes because it is a component of enzymes essential for nitrogen fixation. Deficient levels could result in nitrogen deficiency symptoms. Silicon is found as a component of cell walls. Plants with supplies of soluble 144

“silicon produces stronger, tougher cell walls creating a mechanical barrier to the mouthparts of piercing and sucking insects.” silicon produces stronger, tougher cell walls creating a mechanical barrier to the mouthparts of piercing and sucking insects. Silicon significantly enhances plant heat, drought and cold tolerance. Silicon stimulates the production of polyphenols, part of a plant’s natural defences against fungal and insect attack. Foliar sprays of silicon have also shown benefits reducing populations of aphids on field crops. Tests have also found that silicon can be deposited by the plants at the site of a fungal infection to combat the penetration of cell walls by the attacking fungus. Improved leaf erectness, stem strength and prevention or depression of iron and manganese toxicity has all been noted as effects from feeding soluble silicon. Silicon, known to be essential to members of the poaceae family (grasses), has demonstrated benefits to a wide variety of plants. Silicon is the second most common element in the earth’s crust. However, it is largely tied up in the form of insoluble rock. Hence, it is only available in very low levels in nature, though it is ubiquitous in soil solutes and all water supplies, even rainwater. Even double distilled water contains not less than five ppb of silicon. Accordingly, it is not possible to deprive any plant of all silicon, a requirement for the Arnon and Stout definition of essentiality. MY

Decoded: Fertilizer Injector Usage by Guy Sela

Do the math, learn the lingo Modern fertilization systems include fertilizer injectors that belong to one of two types: fertilizer injectors that are electrically powered (independently or by a controller) and fertilizer injectors that are mechanically powered by water pressure. Both types inject fertilizer solutions into the irrigation water. The ratio in which the solution is injected is termed the injection rate. This ratio can be expressed as percentage or as v/v (volume/volume). For example, a ratio of one gallon per 35 cubic feet means that one gallon of fertilizer solution is injected into each 35 cubic feet of irrigation water. The same fertilizer injector rate can be expressed as a percentage at 0.5 per cent. A higher fertilizer injector rate means more fertilizer solution is injected into the irrigation water.

Factors affecting efficient operation of fertilizer injectors There are three essential factors that need to be considered to ensure an efficient operation of a fertilizer injector: the required injector flow rate, the water pressure and the materials the fertilizer injector is made of.

Injector flow rate The required flow rate of a fertilizer injector depends on: • the irrigation flow rate • the required fertilization level • the concentration of the fertilizer stock solution For reaching a certain fertilization level, higher irrigation flow rates require fertilizer injectors with higher flow rates. For 154

Water pressure and water flow affect the performance of fertilizer injectors. Water flow through the fertilizer injector and water pressure in the irrigation line must be adequate for an efficient operation of fertilizer injectors.”

example, if you want to inject one gallon of fertilizer stock solution into 35 cubic feet of water, and the irrigation flow rate is 1,059 cubic feet per hour, you’ll need a fertilizer injector with a minimum flow rate of 40 gallons per hour. It would be impossible for a fertilizer injector with a lower flow rate to reach the desired fertilization level. Use this simple calculation to check whether your fertilizer injector can provide the required fertilizers quantities: Divide the fertilizer injector flow by the irrigation flow to get the injection rate. For example, if your fertilizer injector flow is 40 gallons per hour and the irrigation flow rate is 1,059 cubic feet per hour, then the maximal possible injection rate is one gallon per 35 cubic feet or 0.5 per cent.

If the flow rate of your fertilizer injector is too low, you can take one of the following actions: • Decrease the irrigation flow rate by irrigating fewer valves at the same time. • Increase the concentration of the fertilizer stock solution. In this case, make sure you don’t exceed the solubility limitations of the fertilizers. Water pressure and water flow affect the performance of fertilizer injectors. Water flow through the fertilizer injector and water pressure in the irrigation line must be adequate for an efficient operation of fertilizer injectors. For example, if the water pressure in the irrigation line is higher than the maximal pressure against which the fertilizer injector can work, the fertilizer solution might not be efficiently injected, and the fertilizer injector might even eventually not inject any fertilizers at all.

Root Pouch’s Ashley Fromm leads us into their imaginarium, the place where creativity lives, and gives MY readers the first look at their new camo line of cloth containers. Maximum Yield (MY): What was the inspiration behind the creation of Root Pouch sustainable products? Ashley Fromm: Growers today are demanding healthier plants that produce bigger yields in shorter periods of time.This could not be done as efficiently with the old tools and older technologies. The Root Pouch fabric line was created to answer these needs. MY: How do you know your containers grow better plants than their plastic counterparts? Ashley: The Root Pouch fabric containers not only deliver the initial benefits we were striving for when first producing the product—such as preventing roots from circling, creating insulation

from winter cold and allowing roots to cool in summer heat—but the fabric containers also deliver additional benefits, which we discovered from talking to growers.These include quicker growing times, better drainage, less water needed and a quicker transition to hardening off cycles. Plants are living, breathing things—fabric pots offer a soft, nurturing, breathable environment for the plants. MY: How are Root Pouch products different from similar cloth containers now available on the market? Ashley: Root Pouch containers are environmentally friendly— just like the plants growing in them. Using materials made from recycled plastic water bottles and additional natural fibers, we have created a variety of environmentally conscious horticulture products. Our products are more versatile and considerably less expensive than their plastic and fabric counterparts.We are focused on reducing the use and need for plastic containers to ensure less waste in the landfills and less use of fossil fuels one garden at a time. MY: What does your imaginarium workshop look like and how does it help spark the designer’s creativity? Ashley: At the Root Pouch headquarters we have a warehouse/ workshop/testing area/think tank.We call it the imaginarium—a place where anyone, anytime can visit and share ideas.We listen to ideas and try to build prototypes to see if we can create the result that people and customers are imagining. Next time you are in Portland come by and see some of these things. Some are a little crazy and some are really cool. Most of what Root Pouch offers originated in the imaginarium; things like our vertical garden pouch that has an origami wall hanger to attach to the wall.This is a new item to look forward to in 2012.

MY: What are Root Pouch containers made of that makes them degradable? How long does it take for a Root Pouch pot to degrade in the soil?

Ashley: One of our most famous and recognized creations that came out of the imaginarium was degradability.We were given the challenge one day of creating a fabric that would degrade (breakdown) in time.We all thought, wow! What if we could actually make fabric out of recycled materials that would— once planted in the ground or ended up in a landfill—actually breakdown.We put a lot of really smart folks together, travelled to three countries and spent a few years of trials and testing and voila—Root Pouch degradable pots. Not just one but five distinctively different degradable lifespans from 15 to 20 months, from five to six years and everything in between. MY: What Root Pouch products are you most excited about right now? Ashley: Our more recent and new creation to come out of the imaginarium just a few weeks ago is really quite fun and interesting. We were asked to make our degradable pots have the ability to blend into their surroundings, to be camouflage.We turned to our military forces for ideas. Root Pouch just launched our new chameleon line for when you just want your pots to blend in.

We now offer our award-winning technology in degradable pots in five different camouflage colors and patterns used by military forces around the world. MY: What makes your products so versatile? Ashley: Root Pouch plant pots can be used to grow plants of any size and type, and are also ideal for transporting plants because they are lightweight, durable and come equipped with carrying handles. Potted plants and trees will enjoy healthy growth while aboveground, and can also be planted directly in the ground, where the pot will degrade to allow the roots to take hold in the natural environment.The Root Pouch plant pot can be used successfully in many different climate and soil conditions, from desert sand to clay. MY: What various products do you offer to American growers? Ashley: We offer a wide range of growing possibilities with our fabrics, both degradable and non-degradable. Our fabric containers, in varying degradable lifespans and colors and camouflaged prints has been the focus of our talk this time, however, we do have other wonderful products: vertical and living wall gardens, Urban Saddlebags perfect for planting over railings, erosion control sacks and net pot inserts. MY: Where can growers in the USA purchase your products? Ashley: You can find Root Pouch product lines at your local garden centers and hydroponic stores. MY: What can indoor and outdoor gardeners expect from Root Pouch in the near future? Ashley: We are often asked, “What’s next?”We are as curious as anyone else.We are always waiting to hear what consumers want. Once they bring an idea to the imaginarium, we promise our people will give the idea a lot of attention, and if we think we can do it, we will give it a try.We are committed to being more than just another fabric pot company; we are committed to be always pushing the envelope, to always be building what works best, offering more choices and better pricing than anyone else. So if you have an idea, we welcome you to bring it to the imaginarium and we would be happy to make it a reality. MY: How can your dedicated and interested fans stay connected to Root Pouch? Ashley: You can learn more about our company and our products on our website as well as social media outlets such as Facebook and Twitter. You can also contact us via our toll free phone number 1-800-801-2053 or We really enjoy working with our customers to answer questions, work on new designs/projects and lead them in the right direction.

It seems like everybody comes to hydrofor their shop already picked out—and it ponics by a different route—some folks seemed to nicely reflect the way they felt get turned on to it by family and friends, about their new business. some people want to grow their own food, “Our first idea was to take the five-star and for some, like Matt Sledge and Josh customer service experience that we had Roman of Art of Hydro in Thousand Oaks, been exposed to for so many years and bring California, their previous jobs just kind of it into the hydro world,” says Matt.“We also lead them into it. believed that we could approach hydroponMatt and Josh were long-time gardenics as an art and then teach people about this ing enthusiasts who were partners in a art.That’s when the idea for the name ‘Art of commercial lighting company.They loved Hydro’ was born.” helping their customers out with their grow The one thing Josh and Matt knew for sure light requirements and eventually decided when they started the new shop was that that they were actually more interested in they didn’t know nearly enough. Although the hydro aspect of the business anyhow— they both had gardening backgrounds, they which is when they started looking for a weren’t really anything more than gifted location to open their new grow shop. amateurs—and that was something they Josh begins their story:“We have always were determined to change. had a passion for gardening.We both began “Art of Hydro opened its doors in May our careers in the customer service industry of 2010,” explains Josh,“but the preparation and then became involved in opening a started long before.We knew that if we were commercial lighting company, but while going to be a successful store, we would have working at our lighting company we began to learn everything about hydro and gardento merge the lighting with our green ing in general.

had to do it right.We had a lot of knowledge to start with, but we believed that that was not good enough—we decided that we would have to become ‘hydro masters’. Educating themselves so they could better assist their customers was just the first step for our ninja garden men—when the shop opened they had no employees, so Josh and Matt had to learn how to do everything by themselves and they put in some pretty crazy hours along the way. “Yeah,” say Matt, “We started with just us. Even today, we both work countless hours. We feel that it is important for us to be present and continue the relationships that we have established with all of our customers. In the beginning we did everything—from stocking shelves to setting up the POS system to sweeping the floors. Only now, after we have grown as a company, have we been able to hire employees and get companies to help us with the outside marketing and internet optimization, as well as shipping and receiving.” Josh feels like the work and study has begun to pay off, though.They’ve got four employees now, they’ve figured out what it takes to keep their customers coming back and their client base is steadily growing. “We believe that a solid reputation plays a huge role in attracting new business. We had to learn how to listen to our custom-

ers and understand their needs and make adjustments accordingly.” Matt continues:“We began to gain market share and recognition by word-of-mouth. We offered a fully stocked store with great discounts and plenty of knowledge.We even had a video advertisement playing in a local movie theater.We embrace a new generation of gardening and we have a rewards program that offers customers an opportunity to save even more money by building up rewards points and then cashing them in for store credit. In addition to these discounts, we randomly select one customer each month from our e-mail list and award them with a $100 gift certificate.We do all this to thank our customers for their loyalty.”

When asked how he thought he and Matt would do in the future, Josh sounded pretty confident. Matt agrees, “The industry itself has grown leaps and bounds in recent years and is ever-evolving. Once an industry that was in the shadows is now an industry that is in lights. We embrace all the latest technological advances and look forward to a bright and green future.” We asked Josh to sum it up for us—what sets Art of Hydro apart from all the others and why should you want to shop there? “We’ve got a great location in Thousand Oaks, California,” he answers. “We carry all major brands and product lines, as well as boutique product lines. We distribute locally from our store and worldwide on the Internet. We stay on top of the newest trends by attending all trade shows, we stay in contact with industry representatives and manufacturers and we welcome suggestions and feedback from our customers. We also have a full e-commerce website.” Matt leaves us with their most recent achievement. “We are proud to say that we were part of a primetime ABC cooking show. On the show we provided multiple full hydroponic gardens to grow healthy fruits and vegetables and we demonstrated how to eat better and live a more healthy lifestyle—and isn’t that what our whole store is all about?” MY Maximum Yield USA  | November 2011

When roofs are covered with soil and plants they last for much longer because the sunâ&#x20AC;&#x2122;s energy is being absorbed by the organic material, so a roof that needed replacing every 10 years might now last 40.



Many houseplants are started in glasses of water, but aloe is native to desert regions and would never experience a glass of water in its natural environment.

Common food plants such as rhubarb, avocado (fruit and foliage) and even the green parts of tomato plants (leaves, stems and green fruit) are considered poisonous to many pets.

A planted roof will cool a building in summer and warm it in colder weather, reducing dependence and stress on building ventilation systems and saving energy.
