ammonia for plants – dangerous or Beneficial?

Homegrown Hydroponics

I love your magazine and online information, but cannot locate a search box, so I will just ask. I thought I read an article in your magazine regarding using ammonia in the garden. Do you recall what ammonia is used for? I bought a gallon of it, and cannot decide what to do with it. I don’t want to destroy my greenhouse plants. I put a little ammonia in a spray bottle, and lightly sprayed the dirt on two planters in the greenhouse, hoping any spiders would scram; and they did. I have been keeping an eye on those plants and so far they show no ill effects, except for one low leaf is turning yellow, which I removed. Thank you for replying to my little inquiry. I appreciate it.

Thanks to Maximum Yield and its contributors for the helpful information and great articles. I am new to hydroponics and gardening and I believe I have found a new passion and lifestyle to enjoy! Over the summer I harvested a variety of tomatoes. I’m looking forward to my jalapenos and anything else I may grow. The goal now is to never have to buy veggies. Thanks again Angel Bueno

Thank you for such a well thought out and put together magazine. You guys and gals are doing a great job and yours is the only magazine I read from cover to cover each month; when I can get a hold of a hard copy, I keep it for reference. I’m so glad that your Long Beach Expo is not the same weekend as the Long Beach Marathon this year. I organize all the volunteers for the marathon and last year you were in the very next room at the Convention Center on Saturday and Sunday; it killed me that I couldn’t make it next door to spend some time walking around, learning and meeting everybody. I have been growing hydroponically for 25 years indoors and am thinking about doing some growing outdoors next year in hydro. Thanks again for all your hard work; it sure shows every month when I get to read the next issue. Thanks Bob Albright Long Beach, California

And Seattle is home to some of the wealthiest people in the world. I really appreciate the information your magazine offers. It has given me the ability to produce maximum yields. Thanks Randy Surdyk


Maximum Yield USA | October 2011

Thanks Sharon Calabrese Ammonia does have a place in the garden. Ammonia can be diluted and used as a fertilizer. A quarter cup of ammonia per gallon of water can be mixed, and the plants can be sprayed with this solution once per week. When ammonia breaks down it releases nitrates, a source of nitrogen. This should only be used on alkaline-loving plants such as sweet peas and asparagus because ammonia is very alkaline. It will actually damage acid-loving plants such as tomatoes. Many types of ammonia contain other ingredients intended only for cleaning and will not be safe for your plants. A safer alternative to using ammonia would be to use pine tree oil or kelp spray. These products can be applied safely to a wide range of plants. Ammonia can also be used to battle mildew growing on soil or on the plant itself. Use the same concentration as mentioned above and apply to the surface of the soil or on the leaves once per week until the mildew is gone. Ammonia is also often used to detour large pests from eating your crops. Outdoors it can be used to prevent raccoons, rabbits, skunks and other animals from getting at your crops. Indoors it can be used to keep your household pets, such as cats or dogs, from getting into your garden. For this purpose the plants do not need to be in direct contact with the ammonia, but it can be sprayed around the general garden area. The idea is that the ammonia will mimic the urine of predatory animals thus keeping the animals that will eat your plants at bay. Ammonia is a harsh chemical with powerful fumes that should not be inhaled. The mixing of ammonia should only be done outside or in a well ventilated room and should only be mixed with water and no other chemicals. If ammonia is mixed with bleach you would essentially make mustard gas, which is highly toxic when inhaled and can be lethal. Thanks for the inquiry, Sharon. Hope this answers your question.

SIMON SAYS Hello Simon, I’m a new reader of Maximum Yield and need your input on a controversial question me and some of my fellow grower buddies have. Is it beneficial—in any way—to monitor one’s runoff water after drenching one’s soil with nutrients? Some say you can see the chemistry between your plant and its nutrients more efficiently, but I personally see it as totally unnecessary. I have never seen the need for it, basically because I always seem to get drastically false readings on my pH pen when testing the runoff, and my plants always look fine if I just stick to controlling the pH level of my nutes before applying them to the soil.

Thanks, Kyle S.

The subject of monitoring runoff water can definitely cause debate among growers. I will fan the flames by saying that wastewater testing is exceptionally interesting and can be important information for a grower. In a recirculating system, the runoff needs to be monitored to ensure an adequate level of nutrition and also that the nutrients in


Maximum Yield USA | October 2011

suspension are available to the plant (based on pH levels). In this case, it sounds like you are in a soil/soilless-based system, so I will try and tailor the answer to that style of gardening. For argument’s sake, I will also hazard a guess that you are growing in a peat-based medium.The first issue of growing in peat is the pH of

the material.With a pH range usually hovering between four and five, using peat for growing plants requires the use of a calcium supplement to boost the pH to a useful range. In most cases, the manufacturer will add lime of some sort to buffer the pH up. This is the first reason for you to check your runoff.The buffering effect of the lime only works for a certain amount of time, especially with frequent watering.After this point, the pH of your medium will drift lower and lower. Knowing when the pH starts to drop is an important management tool, especially if you are going long periods without transplanting. Runoff pH can also be affected by the plants themselves. Plants have an internal pH regulating system and they can also affect the localized pH around the rhizosphere by releasing exudates to suit their needs. The interactions at the root zone can affect the pH of runoff. The last major reason that your runoff pH can fluctuate is the presence of biology in your medium. Microbes tend to affect their environment. If you have ruled out fertilizer, medium and plant interactions as causes of pH drift it could be the microbiology. In a bacterial-based system, the pH will generally drift up. In a fungalbased system, which is more beneficial but far more difficult to manage, the pH will drift down. I would think that your point of inaccurate readings of the runoff water you have tested relates to one of the issues above. It is entirely possible for the pH of water leaving the medium to be much different than the solution you are top feeding to your plants. Remember to keep your testing equipment clean and calibrated to be on the safe side of accuracy. Given the way people like to over-apply fertilizer, another very important reason to test runoff is to see how much of your money is being wasted, and also if your plants are close to a nutrient absorption issue. Peat has a cation exchange rate, meaning essentially it can retain certain types of nutrients. Once these exchange sites are saturated, the nutrients in solution can reach levels that can harm your plants. Assessing the runoff concentration can, in this case, help you stop overfertilization and avoid damage to plants. It will also show you if high levels of soluble nutrient are draining through your medium and away from plant roots. The problem in assessing the salt level is that you do not know the specific elements that are causing the reading. In commercial operations, the readings are broken down into elements from either solution or tissue samples taken throughout the crop lifecycle.Through this, the grower can adjust nearly every aspect of their operation, from medium to fertilizer input. For the average home grower, these tests sometimes cost more than they are worth. In your case, when you look at your plants and they look healthy, that is the best observation possible. Experimenting is a great thing but a healthy crop is just as important.

Slow Food’S 1,000 SuStainable GardenS For aFrica One thousand gardens are blooming across Africa, where the international organization Slow Food is helping schools, villages and other communities grow fruits, vegetables and herbs using sustainable water management, pest repellent and fertilizing techniques. In Uganda, most of the food that makes up the daily diet is imported. The country’s soil is rapidly losing fertility, local varieties are disappearing, young people are abandoning the countryside and contempt for farming work is widespread (schoolchildren are often sent to work in the fields as punishment for bad behavior). In this context, a project was launched in 17 schools, with a total of 620 students. Scholarships have enabled some young people from Africa to study at the University of Gastronomic Sciences in Italy and then return home to help their communities strengthen their economies and protect their cultural identities.

bumblebeeS: to FiGht or taKe FliGht

Due to disease problems in the late 1990s and declining bumblebee species, many greenhouse growers now use commercially produced Bombus impatiens, a generalist pollinator native to the Midwest and Eastern United States and Canada, to pollinate their crops like peppers and tomatoes. But scientists are concerned about using a bee outside its native range, and some western states restrict the import and use of non-native bees. If B. impatiens were to escape and form wild colonies in the western United States, they could compete with native bees for food and resources and expose native bumblebees to pathogens they are ill equipped to combat.

Most surfactants are petroleum-based, but an Illinois team of scientists and microbiologists has focused their-attention on sophorolipids, surfactant-like molecules produced by naturally-occurring yeasts. Only a few Candida yeast species had previously been shown to make the sophorolipids—most notably, C. bombicola and C. apicola, which boast the highest sophorolipid yields.

High-quality food should not be a trend, nor should it be exclusively available only to those who can afford it. Although organic produce can be pretty expensive when purchased from the supermarket, there is one great way to reduce the cost— grow it yourself! It’ll take some time to get up to speed and it’s likely you’ll experience some challenges, but whatever effort you put into growing healthy, organic produce will eventually come back to you in lessons learned and beautiful produce grown for you and your family to enjoy. And you’ll be in control: growing your own food will allow you the freedom to be self-sustainable to the extent you desire. How much work or effort you are willing to put in will influence the outcome in terms of taste, aroma and final fresh weight of produce, but a little patience, some hard work and a bit of reading will have your organic garden up and running. The beauty of growing 46

plants year-round is that anyone can do it—beginners, advanced horticulturalists and everyone in between are capable of producing excellent results. Over the years, organic gardening has developed into a pretty aggressive global trend. It can be applied indoors or out yearround using virtually the same materials for both hydroponic and soil-based systems. Some may think organic farming is messy and requires a lot of mucking about with muddy, soupy or

dusty ingredients—while this is true to a certain extent, there are a variety of clean products and techniques that can help the grower achieve superb organic results on a small- or largescale, all while staying relatively clean and dry. The techniques required are simple: with water-soluble tablets, place one in a gallon of water, shake and feed generously into the root zone; with refined liquid concentrates, apply at the rate of one tablespoon per gallon of clean water; with hose-end applicator systems, just attach, turn on the water source and apply to lawns, flower beds, vegetable gardens or trees; and with dry granular mixtures and powders apply one tablespoon per gallon of grow medium as a top dressing, pre-mixed into the soil or diluted into clean water. It seems that the refining technology implemented in fertilizer manufacturing has vastly improved across the industry in recent years, allowing growers to enjoy higher-quality results, whether in hydroponics, soil–based or soilless systems. One-part organic nutrient systems are great for those beginners, novice and even advanced growers who want to grow premium-quality organic produce without too much complexity in their fertilizer regime. Two bottles are all that is required: one comprised of a blend to promote vegetative growth and another containing a formula to stimulate flowering and fruiting production, if necessary. All-purpose one part systems also exist that consist of a single bottle that is used for all stages of growth and bloom. These types contain a fairly balanced N-P-K ratio, with adequate trace elements and micronutrients.


Maximum Yield USA | October 2011

Required dilution ratios may increase or decrease throughout the various growth stages, but only one bottle is needed for the entire lifecycle of a plant. These all-purpose one part systems are obviously the simplest method for the novice grower to handle, as there is only one bottle used instead of two. These solutions can actually be a very clean and simple way to provide your crop with an array of organic nutrition derived from botanical or other natural by-products such as kelp, worm castings, seabird and bat guanos, humus, blood meal, compost, molasses, fish emulsions, hydrolysates and more. Newer proprietary formulas even boast perfuming agents such as lavender, citrus or grape to further enhance the user-friendly appeal and

and removing much higher levels of contaminants from the water supply. For those growers wanting to take it up a notch from the all-purpose or one part nutrient systems, try implementing a granular or dry organic fertilizer mix as a top dressing to established or newly planted seedlings and cuttings, in conjunction with your chosen liquid nutrient solution. These mixes, which are pretty much idiot-proof when applied as directed, are relatively inexpensive compared to some liquid organic systems and provide a slow, time-released effect that allows the plants to absorb what they need as they need it. One part nutrient systems or dry organic fertilizer mixes used alone or in combination should produce lush growth and thick fruit sets with absolutely no need for cheap box-brand chemical fertilizers. Gardening on a windowsill, near a sunny window or in a sunroom are all great ways to grow healthy crops organically without the added expense and energy usage of indoor lights. Organic soil, coco and other soilless mixes all work effectively in wicking/capillary systems, one of my preferred methods for sun-kissed plants. These systems use a reservoir underneath the growing container portion of the system and allow the desired grow medium to transfer water from the reservoir up to the main portion of the root mass with no wicks required. The reservoir may have molded slots protruding from the base upwards that are filled with small amounts of the desired growing 50

media—organic soil, coco, peat or whatever you have chosen to employ. The main growing container holding all of the media and the root system has cutouts that connect the soil-filled slots in the reservoir to the soil mass in the main container. Capillary action occurs as a result and ensures that consistent moisture and air ratios are maintained in the root system, ensuring root health and reducing the probability of infectious disease.



Plants are still plants at the end of the day, meaning the artificial environments we construct to raise them indoors can never be completely fail proof. The finest equipment, lighting and grow formulations are only ever as good as the operator in control of production. It is still not rocket science, though—water, air, nutrition and light provided in the correct proportions and increments will lead to plant growth. Organic gardening, when done properly, will renew and revitalize soil rather than deplete it, conserve water as opposed to polluting or wasting it and preserve heirloom genetics instead of diminishing them. As an avid follower of hydroponic and indoor gardening-related technologies, I highly recommend starting an organic gardening project for yourself—you’ll be delighted to discover how simple it can be to keep your footprint small and still produce quality, organic, homegrown grown produce.

that is located between photosystem II and photosystem I; more specifically, it occurs at the thylakoid membrane. Initially, in photosystem II, a water molecule is split up (the Hill Reaction) into an oxygen molecule, two electrons and four protons (H+). As discussed earlier, the two electrons are sent to a state of elevated energy due to the absorbance of light energy by chlorophyll molecules as well as some other pigments. Then these electrons proceed to move to photosystem I via a protein

This energy is not just lost though. It is used to pump the protons that were released from the splitting of water across the thylakoid membrane from the stroma region of the chloroplast into the thylakoid. Pumping all of these protons across the thylakoid membrane sets up an electrochemical gradient, which drives the synthesis of ATP. Protons naturally will try to flow down the electrochemical gradient, from high potential to low potential. In this case the protons will try to move back into the stroma from the 58

Maximum Yield USA | October 2011


Photosynthesis and Plant nutrition 2

thylakoid. The protons move back across the thylakoid membrane into the stroma through an enzyme called ATP-synthase. When they move through this enzyme, into the stroma they are moving to an area of lower potential. The protons then must lose some energy along the way, right? Well they do, and this energy is used to put an inorganic phosphate ion, denoted Pi, to ADP, thus creating ATP. Inorganic nutrients are very crucial to the functioning of this process. Iron, sulfur and copper are all parts of proteins that are critical in the movement of electrons from photosystem II to photosystem I. Calcium is also very important in this process because it maintains membrane integrity. Obviously, this is very important when considering the flow of protons and electrons across the thylakoid membrane. Phosphorous too, plays an important role. Not only is phosphorous added to ADP to form ATP, it, like calcium, is important in maintaining membrane integrity. Toxicities, not just deficiencies, can have a detrimental effect on photophosphorylation. One well documented toxicity that can have adverse effects on the production of ATP is ammonia toxicity. When ammonia reaches toxic levels in the plant, one of the many problems that can occur is the uncoupling of photosynthetic phosphorylation. The production of ATP becomes uncoupled due to the detrimental effects of ammonia on the thylakoid membranes. As mentioned earlier, the functioning of the thylakoid membrane is integral in the production of ATP. When the membrane becomes distorted in any way, ATP production will inevitably fall, and the plant will suffer. Thus, it is important to not only know if you are deficient in an inorganic nutrient 60

Maximum Yield USA | October 2011

but to know when nutrients may be at toxic levels as well. This is why tissue testing should be done on a regular basis. It is evident that inorganic nutrients have a major impact on the light reactions of photosynthesis. Nitrogen is in every amino acid in a plant; thus, it must also be part of every single protein in a plant as well as being a major component of the chlorophyll molecule. Nitrogen is involved in nearly every aspect of the light reactions as well as photosynthesis as a whole. Phosphorous also plays a big role in the light reactions of photosynthesis. It is phosphorous that is added to the ADP to form ATP that will be used elsewhere in the plant for energy. Phosphorous is also part of NADP, which is reduced to the NADPH2 that goes on to the Calvin Cycle. Magnesium is the central component of the chlorophyll molecule and therefore is vital to the functioning of the light reactions of photosynthesis. Research has shown that up to 10 per cent of the magmag nesium in the plant is held in chlorophyll. Manganese, chlorine and possibly zinc are essential for the Hill Reaction to function. Iron, sulfur and copper are all parts of proteins that help move electrons between the two photosystems.

THE DARK REAC TION/ CALVIN CYCLE The Calvin Cycle is often referred to as the dark reaction of photosynthesis, which can be misleading as the Calvin Cycle can occur both during day and night. However, light is not Maximum Yield USA | October 2011


Photosynthesis and Plant nutrition 2


required for this reaction to proceed; hence the name. In the most general terms, the dark reaction of photosynthesis involves the evolution of carbon dioxide from the atmosphere into the plant where it is used to manufacture carbohydrates. The actual cycle is much more in-depth than that, however. Once again, inorganic nutrients play an important role in the many facets of the dark reaction of photosynthesis. As in the light reaction, inorganic nutrients have both direct and indirect effects on the dark reaction.


Maximum Yield USA | October 2011

The dark reaction of photosynthesis begins with the diffusion of carbon dioxide into the leaf via the stomata, while oxygen— created in the light reaction—diffuses. One plant nutrient that plays an essential role in the movement of carbon dioxide into the leaf is potassium (K). Carbon dioxide moves into the leaf through the stomata. The stomata, which are located mostly on the underside of the leaf, can be opened and closed by a plant as needed. The opening and closing of the stomata is regulated by guard cells that are located on either side of the stomata. The movement of potassium into the guard cells will determine whether they allow the stomata to remain open or closed. With potassium deficiencies, there will be problems in the movement of carbon dioxide into the leaves, as well as movement of oxygen out. Without much needed carbon from carbon dioxide, the plant may have to resort to mining carbon from inside the plant itself in order to manufacture much needed carbohydrates that will be used in respiration. In addition, oxygen has an inhibitory effect on photosynthesis, and when levels of oxygen inside a plant get too high, photosynthesis rates may drop. Once carbon dioxide has diffused into the intercellular spaces of the leaves, it then moves into plant cells where it is transported into the chloroplast so that it can be integrated into a carbon skeleton via the Calvin Cycle to form the precursors of starches, sugars, proteins and fatty acids. The Calvin Cycle begins with one molecule of carbon dioxide entering the cycle and combining with ribulose 1,5 bisphosphate, a five-carbon sugar to form a series of three-carbon compounds. This reaction is catalyzed by the enzyme rubisco. Rubisco is important because it is thought to be the single most common protein on

Maximum Yield USA | October 2011


Photosynthesis and Plant nutrition 2

the planet Earth. In addition, magnesium and perhaps manganese are essential for the functioning of this enzyme. Without the presence of at least one of these elements this enzyme will not function, carbon dioxide will not be fixed by ribulose 1,5 bisphosphate and the Calvin Cycle will not proceed. After going through a reduction stage a molecule of glyceraldehyde three-phosphate, a three-carbon compound is produced. Glyceraldehyde three-phosphate is then used in the synthesis of sugars, starches, fatty acids and proteins. Ribulose 1,5-bisphosphate is then regenerated and sent to combine with another molecule of carbon dioxide. A question could then be posed: How is glyceraldehyde three-phosphate, a three-carbon compound produced and ribulose 1,5 bisphosphate, a five-carbon compound, regenerated while only adding one molecule of carbon dioxide? The answer is that the cycle must turn three times, thus adding three carbon dioxide molecules in order to produce one molecule of glyceraldehyde three-phosphate. Most of the glyceraldehyde three-phosphate that is produced, moves into the cytosol of the cell where it is used in a variety of reactions. Most of the glyceraldehyde three-phosphate that remains in the chloroplast is converted into starch and stored temporarily as starch granules that are later exported to the rest of the plant for use.

TRANSPORT OF PHOTOSYNTHATE After the products of photosynthesis—sugars, starches, fatty acids and proteins—are formed they must be moved from their point of origin or source, to a location where they are needed—a sink. Photosynthates are moved around the plant via the phloem tissue. Two elements in particular are crucial for the movement of photosynthate from source to sink. Potassium, in addition to its many other roles in the plant, serves to transport the products of photosynthesis around the plant. When organs such as flowers are forming, there is a great need for potassium in a plant. When deficiencies in potassium occur, there is often decreased flower set or a decrease in flower size and quality. The importance of potassium during times of high metabolic demand cannot be understated.


Maximum Yield USA | October 2011

Calcium is also important in the movement of photosynthate around a plant. Calcium has been found to be important in the loading of the phloem with the products of photosynthesis. If calcium were deficient, there would be problems with getting photosynthate into the phloem tissue and thus it would not be available to sink areas on the plant.

What You’re Eating? SafEly ConSumEd by Ed Harwood

Food safety should not be a consumer concern; they have enough to worry about. Food safety needs to start with the grower. When food is grown hydroponically, there are added challenges. Read on to find out what those are and how to overcome them.


Maximum Yield USA | October 2011

do you know what you’re eating?

What is Food saFety? One of the concepts that needs to be in included in the definition of sustainability is that of food safety. Let’s face it, if you can’t provide a safe product, your business is not likely to be sustained, nor will you have the resources to be sustainable! The Food Safety Modernization Act (FSMA)—passed in January of 2011—does not apply to businesses that produce less than $500,000 in sales annually and the FDA is still determining what other factors will require a facility to register. This does not mean, however, that the steps bigger producers are taking can’t inform smaller operations about safety considerations and processes. In fact, your customers may insist that you follow some of these practices. To begin, let’s imagine what might be behind the need for a food recall. If contaminated food makes it through the distribution process to the recall stage, it had to have been contaminated somehow, it had to make someone sick or caused death and it now must be traced back to the grower or handler, who will suffer consequences. On top of the inevitable brand damage, the real damage will occur if the producer can’t quickly and efficiently trace the source of the contamination (in order to stop it) and the product affected (to get all of the contaminated product out of the food chain).

“The Food SaFeTy ModernizaTion acT (FSMa)—paSSed in January oF 2011—doeS noT apply To buSineSSeS ThaT produce leSS Than $500,000 in SaleS annually.”

This is deadly serious business—if you can’t find the source of the contamination, then you risk another recall and the certain demise of your business.You can imagine what a recall will do to your customer relations and how difficult it will be to face the press and answer questions about the product affected.

Food safety is a serious topic. In the annual report for 2010 the 229 primary industry and regulatory Reportable Food Registry (RFR) entries that would be of most concern were: Listeria monocytogenes at 14.4 per cent; E. coli O157:H7 at 2.6 per cent; ‘other’ at seven per cent; foreign objects at 1.3 per cent; and Salmonella at 37.6 per cent.


Maximum Yield USA | October 2011

Although some of these entries are from foreign products and few are from things grown hydroponically, it helps to identify what we need to watch for and prevent from getting into our food. It is reasonable to believe that we can avoid many of these risks by growing in a protected environment, but it is true that we cannot avoid all of them. Nothing about hydroponics is inherently completely safe, although as a growing method it may be potentially safer than outdoor farming. You should note that a recall is not something that the size of your annual sales or the type of farm you operate will necessarily always help you to get out of. The FDA, via FSMA, has the duty to order recalls based on presumed contamination and the rules will be

collection of related steps that reduce the risk of contamination, although no process or program can guarantee safe food—there will always be some risk involved. The FDA maintains a website that details easy steps for compliance and it should be obvious that utilizing the resources of the government in this fashion demonstrates appropriate concern for people’s wellbeing, even if you might initially see it as meddling or heavy-handed. The FDA will require you to have records that will allow you to retrieve purchaser information easily and rapidly.You are also obligated to keep records that will allow you to identify the source of all products and related processes. You must learn the rudiments of food safety even if you give food away. Prevention of contamination is your primary tool in keeping food safe. Assuming that you only use fertilizer and no other chemical inputs, then your main concern will be microbial contamination. All microorganisms require water, food and appropriate temperatures to thrive and the removal of any of these conditions for life will create safer food by reducing the reproduction of harmful organisms or promoting their death. Although microbes don’t do well when dried out, this happens often in their world so they have coping mechanisms and can return quickly when exposed to moisture again. Microbes like food as well, but most of the time we can remove their favorite foods by using care in sanitizing our processes and tools. Washing hands and wearing gloves, only handling food when we are well and keeping our tools clean are important rules that must always be observed.You should also remember that sanitizers are not generally effective unless used on a cleaned surface. The rule that is most important to remember as it relates to food production is temperature control.With few exceptions, produce has a longer shelf life when it is kept cool.A harvested plant begins to deteriorate as soon as it is cut and the faster we cool it, the less deterioration occurs. As soon as we allow the harvested food to warm up again, the deterioration begins anew. Interestingly, most refrigerators are not cool enough. Do you have a thermometer in yours?

hoW do We achieve loW risk oF Food contamination? The best place to start with food safety is before it leaves your control. Contaminated product that has not left your facility is not required to be reported because it does not yet pose a threat. After products leave your facility, the threat is real and must be reported. So, let’s focus on what to look for and what to do. The industry uses HACCP (Hazard and Critical Control Points) to formulate prevention plans to avoid food contamination. There are third-party organizations (meaning neither you nor the government runs them) that will help construct these programs and certify that you meet the requirements. The HACCP system is a method to identify each hazard that could befall your product and show where it requires control. The steps supporting the method are fairly simple—first, assess the hazards; then determine the critical control points, the limits and monitoring procedures; and finally, establish corrective actions, verification procedures and a record-keeping system. As a grower doing your best to comply with these requirements, you will need to assess your preparedness: 1.

Composting with earthworms, or vermicomposting, is great for apartment dwellers who don’t have yard space, and for homeowners who don’t want to hike through snowdrifts to a backyard compost bin; and kids love keeping hundreds of wigglers for pets.

Covered Bin Your worms can live in a plastic bin or wooden box with plenty of air holes punched in the sides and top. Line the worm bin with nylon net to keep the small ones in. Holes in the bottom are needed for drainage, so you’ll want a tray under the bin.You may find it more convenient to have several smaller, more portable units rather than one large one.

Bedding Loam or black topsoil makes particularly good bedding material. Bedding can also be shredded newspapers, soaked to soften the edges (the worms will eat this too, so avoid colored inks and glossy paper) or a mixture of sawdust, peat, shredded leaves and soil. Fill the bin with about a foot of bedding, about as damp as a wrung-out sponge—not soggy and not dry.With a lid on the bin and regular feeding of the worms, maintaining the correct moisture level shouldn’t be difficult.

worms You’ll want the kind of worms that are sold for fishing bait—red wigglers or brandling worms. Redworms normally live in barnyard manure piles and feed on fresh organic material.Your valuable little redworms will live quietly in their dark box and multiply rapidly. Just bury your leftovers in their bedding after each meal. It is unlikely that you will have too much waste to compost (redworms will eat their own weight in kitchen scraps and bedding each day).The castings they produce are incredibly rich fertilizer and look like finetextured soil. For each cubic foot of worm bin, plan on using a half pound of red wigglers (about 500 depending on their size).

Food Coffee grounds, vegetables and fruit are the recommended food for worms. A varied diet is important. Avoid bones, dairy products,

meats, garlic and potato peelings—what doesn’t cause odors or attract insects will simply take a very long time to breakdown. Eggshells are essential to keep the bedding from becoming too acidic for the worms. Dry them well, crush them and sprinkle the tiny pieces over the top of the bedding.

temperature Redworms will survive in temperatures from 41°F to 90°F but prefer it at or above room temperature. If you keep the worm bin outside in good weather, be ready to bring it in promptly when the temperature drops.

harvesting the Castings Removing the compost couldn’t be easier.You will notice that redworms hate the light; they’ll wriggle down into their bedding whenever you take the lid off the bin. Every few months—when the castings outweigh the bedding that remains—place the opened bin under a very bright light and give the worms 10 minutes to get well away from the surface. Then the coast is clear for scraping away the worm castings from the top layer. When you start to see the worms again, keep the light on them, give them another 10 minutes to go deeper still and remove the next layer of compost. Keep going in this way until the harvest is done. Then fill up the bin with fresh bedding and start again.

outdoors Some people build special worm pits to take advantage outdoors of the worms’ natural talents. To make a worm pit, all you have to do is dig a square hole a couple of feet deep and set a bottomless box over it. The compost materials and worms are tossed in here.You can keep adding organic waste as it accumulates. Keep the pile damp and dark and the worms will do the rest. Remember to harvest your compost carefully—in bright sunshine—to save the worms from an unpleasant fate. They won’t live long if they’re stranded in ordinary garden soil, dumped there with a forkful of compost. MY Article supplied by the New Brunswick Department of Environment (

the scented Oasis Cultivate a perfumed paradise indoors by dr. lynette morgan Many of the hydroponic plants we grow are destined to become food or flavorings, some are planted purely for visual effect and then there are those that appeal to another important sense—smell. Aromatic plants have been an important part of horticultural history ever since humankind discovered the vast array of scents and essential oils that plants could produce. While it can take tons of plant material to produce decent quantities of scent extract, growing aromatic plants indoors can still be a pleasant and rewarding experience.

The importance of aromatics

Aromatherapy, which has long been part of some medical traditions, is used by many people these days as a way of helping to deal with illness and daily stress and for relaxation and meditation. Medieval healers used to prescribe walks through scented gardens as a way of restoring health and spirits. Smell is one of the most powerful of our senses since it is linked to parts of the brain that deal with and process emotions. When the tiny volatile particles of aromatics in the air released by plant material are inhaled, they stimulate the olfactory receptor cells in a process termed olfaction. These impulses are then transmitted to the limbic system, which is connected to areas of the brain dealing with memory, breathing and blood circulation. How these systems are stimulated depends on the properties of the fragrance. Since smell directly stimulates the memory centers of the brain, certain scents can trigger memories and emotions. Many people also believe that certain plant aromatics can either energize, such as peppermint, or relax, such as lavender.

Hydroponics and scented plants

Hydroponics offers a unique opportunity to grow aromatic plants. Woody, hardy aromatic species such as thyme, sage, rosemary, lavender and scented geraniums will concentrate the aromatic oils that produce their characteristic aromas when grown

under slightly stressful conditions. Outdoors, this would mean high light levels, warm temperatures and moisture stress; however, we can replicate this effect in hydroponics by increasing the EC of our nutrient solution. Pushing EC in the root zone to much higher levels than we would normally use for leafy herbs reduces the amount of water taken up by the plant and held in the foliage, thus allowing the scented oils to become more concentrated. High EC levels combined with a free-draining medium and good lighting can intensify this effect to an even greater degree, and while less vigorous foliage growth will be recorded under these conditions the aromatics can be increased significantly to levels much higher than would normally occur under protected growing conditions. Hydroponic systems for scented plants can be as varied as the plant species themselves. Many of the Mediterranean aromatic plants such as rosemary, sage and thyme perform best in very free-draining media—such as coarse perlite—as they are intolerant of overwatering. Succulent plants such as mint and lemongrass prefer a more moisture-retentive growing medium and will produce well in NFT, aeroponics or other solution culture systems, although their growth rate can be rapid and they have a tendency to become invasive if not regularly pruned, divided, cut back and generally contained. Nutrient solutions for aromatic plants can be as simple as vegetative formulations for young plants, switching later to bloom mixes for those that produce flowers. A potassium supplement or booster is a good additive for many aromatic plants as they come to maturity combined with a gradual increase in EC as the plant develops. 86

Old fashioned petunias make a great display and will also perfume the air.

Indoor growing conditions may also be varied. In general, warm, humid conditions produce rapid and occasionally excessive foliage growth, which does not always correlate well with a high level of aromatics in the plant. Slower growth often concentrates the aromatic compounds in many species. Most aromatic plants are also just as prone to pests and diseases as other species, despite what is sometimes believed about aromatic compounds repelling insects. Whitefly in particular love basil plants and the aroma doesn’t appear to be any sort of deterrent. Aphids, thrips and mealy bugs are insect pests common to many herbs and other scented plants and need immediate control with soft sprays (such as those containing neem) so that the resulting plant material can be safely used for aromatherapy.

Scented plants for indoors spaces A scented garden is the simplest form of aromatherapy—some plants may directly waft their scent into the air, particularly when conditions are warm and volatile oils are being naturally released. Other plants may need their foliage gently crushed to release sufficient aromatics. Some natural plant scents can be very

strong in a small enclosed area, while others provide delicate background notes of perfume. Most people assume that flowers are responsible for most of the scent in the plant world but this isn’t necessarily the case. There are many plants with scented foliage and even some fruits contribute olfactory delights—aromatic oils such as lemongrass, peppermint and eucalyptus come from plant foliage, while lime, lemon and orange scents can be extracted from citrus fruit peel. Scented foliage has the benefit of providing aromatics at all stages of growth—even young seedlings tend to have some characteristic scent—whereas flowering can be rather seasonal or short-lived in other plants. However, for the indoor gardener looking for a splash of color and some scent, some of the dwarf annuals such as snapdragons can provide both within a relatively short timespan.

sCented herbs

Most of us are familiar with at least some of the scented herb species since many also have culinary uses as well.The way we smell aromatics in plants is actually very closely linked to our sense of taste. Much of the flavor we associate with aromatic plants is actually due to the interaction of olfaction and taste that occurs when plant cells are broken down and volatile compounds released. Since we can only really distinguish five main elements of taste—salt, sweet, sour, bitter and umami—it’s the many thousands of volatile compounds we can detect through our sense of smell that contribute

most to the actual flavor we think we are tasting in our food.The most common scented herbs grown for aromatic uses are sage, rosemary, thyme, basil, lemongrass, bergamot, mint, lemon balm, oregano, marjoram and lavender. Many herbs such as basil and mint demonstrate a range of scent overtones within the same species; varieties of basil include lemon, cinnamon, clove scented and Thai, while mint can be found as spearmint, peppermint, apple mint, chocolate mint and a few rarer varieties, each possessing its own unique aroma.

sCented geraniums

Among fragrant plants well suited to indoor gardens are scented geraniums, tender perennials of the genus Pelargonium. These geraniums, which were widely grown in the Victorian era and had a range of uses from scented garden displays to perfumes, potpourris and cooking, are now coming back into fashion among gardeners. Scented geranium plants are widely available and most need to be propagated from cuttings to retain their aromatic characteristics. The range of scents available within this plant species is truly incredible and sometimes almost hard to believe—most have strong and distinct aromas and some can even be used in baking! Scented geraniums perform well in hydroponics—they do need regular trimming to be kept compact and perform best in media-based systems with a moderately high EC level. Good airflow is also essential to prevent fungal disease and the plants generally don’t tolerate overwatering or a saturated growing medium. Keeping the growing medium slightly dry not only increases the intensity of the scent but also helps prevent disease. Some of the most popular scented geraniums fall into categories like rose scented, citrus scented, fruit scented, mint scented, spice scented and pungent scented, with a wide range of specific cultivars within each scent category. Rose scented geraniums (Pelargonium graveolens) are grown commercially for the extraction of essential oils from their foliage, which is used in the perfume

industry. Common rose scented varieties include Attar of Roses and Grey Lady Plymouth, although there are many others among the rose scented types also worth growing. Of the citrus scented geraniums some of the more common are Citronella (lime, lemon or orange scented) and Rober’s Lemon Rose.The most distinct and easy to grow of the mint scented geraniums is Pelargonium tomentosum, which has highly aromatic peppermint scented foliage and the advantage of being able to be propagated by seed.

pine, cedar, balsam, woody, spicy and lavender scents.


Flowering plants provide a fairly diverse range of scents, colors and plant forms, but for indoor gardens dwarf varieties are often the best suited as they don’t need to be staked or supported and they often flower much sooner than the taller types. Lavender is perhaps the best-known aromatic flowering plant and will grow indoors if sufficient light and space is provided. A dwarf strain such as lavender dwarf Munstead (Lavandula angustifolia)—which only grows to 12 inches high but produces that true olde English scent—is a good choice for indoor gardens. Of the dwarf annual or perennial flowers, those with the most pronounced scents are the flowering stock (night scented varieties in particular), which include certain strains of dianthus, lily, aquilegia, flowering tobacco (Nicotiana), sweet pea, old-fashioned petunia, wallflowers and violets. Many bulbs are also highly scented, and although the outdoor flowering season may be short for these species, they can be grown year-round with the use of artificial chilling (which involves refrigeration for several weeks) and warm indoor growing conditions. Favorite scented bulbs include freesia, hyacinths, tuberose, lily of the valley, jonquils, scented tulips, narcissi and scented lilies. In hydroponics, bulbs are best supported in either a freedraining medium or in specific bulb-production systems, which hold the bulk of the bulb above the flow of nutrient solution to prevent rot. Bulbs are an excellent short-term flowering crop for many indoor situations as they can be forced to bloom out of season, and they provide compact but bright and fragrant displays. Fragrant gardening is a somewhat novel approach to utilizing hydroponics in order to create relaxing and inviting indoor spaces where color and aromatherapy can combine. With some careful attention to the right blend of fragrances and foliage you can create spectacular ambiance in any indoor area. MY Maximum Yield USA | October 2011

After all, it’s the birthplace of the Renaissance, the movement that brought about a revolution in art and science. It’s a land that lovers dream of, a place of culture and the source of many of the world’s finest wines. And what better to accompany some of the planet’s best wines than some of the tastiest cuisine on earth? Italy is so well known for its superb cuisine that it has inspired food trends across the globe. There are not many places in North America where you cannot find good Italian food and the same is becoming true almost anywhere you may travel. Authentic Italian cuisine really is one of the world’s most desirable tastes and this can be traced back directly to the quality of the produce that is being used. Although many ingredients that are typical in Italian kitchens today are not originally native to Italy, they’ve found a home there due to their importation during the age of exploration; and the introduction of beautiful components such as tomatoes and basil from other countries has influenced modern Italian cuisine profoundly. It is no wonder many gardeners are now trying to bring the Italian garden home and indoors when Italian food makes use of so many wonderful ingredients!

hydroPonics. italian style.

In this installment of our International Edible Gardens series we will discuss a few of the vegetables, herbs and greens that are typically found in Italian cuisine. The tomato has become synonymous with Italian cuisine and is used in pasta sauces, pizza sauce, salads and bruschetta; it is cooked, eaten sundried or just enjoyed plain. It seems there are thousands of uses for tomatoes in Italian cuisine, but this has not always been the case. In fact, tomatoes originated in South America, most likely in what is now modern day Peru. It is argued that tomatoes were first brought back to Europe by the Italian explorer Christopher Columbus (working for the Spanish) or by the Spanish explorer Hernando Cortez. Apparently these first tomatoes were a far cry from the tomatoes of today, however—the Italian word for tomato is pomodoro, which translates to golden apple.Through generations of selective breeding the tomato has changed over the years and there are now countless varieties to enjoy, many with very different characteristics and their own distinct flavors. The classic Italian tomato is the Roma and of all the different Roma tomato varieties there is one that truly stands out— the San Marzano tomato is considered by most chefs worldwide to be the absolute best sauce tomato and it must therefore be included in any indoor Italian garden. It is also known to be the only tomato sauce to be allowed on true Neapolitan pizza. San Marzano tomatoes can be grown easily indoors in soil, hydroponics or any other available medium.They are a bright red vine/plum tomato similar to the common Roma tomato, but thinner and a little pointier. San Marzano tomatoes are rich in flavor with few seeds, making them ideal for sauces and canning. They reach about six feet high and usually require staking to avoid plant damage.This particular tomato is an indeterminate variety, meaning the fruit will develop gradually, and the plants will mature in 75 to 85 days.The ideal pH range for San Marzano tomatoes is between 5.8 to 6.8 in soil and 5.8 to 6.4 in hydroponics. For these tomatoes to thrive indoors they require lots of light and so should be grown under HID (high intensity discharge) bulbs. These light bulbs best imitate the conditions of a plant exposed to full sunlight, but they’re strong—so keep them far from the fragile seedlings and gradually bring them closer to the plants as they mature.When the plants are more mature you can keep the lights roughly a foot away from the plant tops. 98

To keep San Marzano tomatoes in their vegetative phase requires 18 hours of uninterrupted light followed by six hours of uninterrupted darkness, while to have your tomatoes bloom indoors you’ll have to change the photoperiod to 12 hours of uninterrupted daylight followed by 12 hours of uninterrupted darkness. San Marzano tomatoes are open-air pollinated and are considered an heirloom strain.To pollinate them indoors you’ll have to be creative—by touching the end of a small paintbrush to each flower several times a day you can effectively spread pollen from flower to flower, pollinating the plants. Soon after this process the plants will begin to produce delicious San Marzano tomatoes, which can then be picked when ripe and enjoyed. There are a variety of different edibles typically grown in an Italian garden and greens must be included in any respectable plot, so we’ll have to discuss a few types of Italian greens that can be grown indoors easily. One of the seemingly endless varieties of Italian lettuces is the Mortarella Verde, an Italian romaine variety with long green leaves that form a tall, compact head. Mortarella Verde is considered very tasty and tender. Another great lattuga or lettuce is Lollo Bionda, a mediumgreen loose-leaf type with thick, ruffled leaves. A flavorful variety with a slightly bitter taste, Lollo Bionda is known to have an excellent shelf life, meaning it can survive several days in the fridge or in any cool space. Lollo Rossa, another loose-leaf variety, is Lollo Bionda’s red cousin, a tight rosette of blood red or violet ruffled leaves with a pale-green base. The Lollo Rossa is considered to be quite bold, with a slight bitterness and a subtle nutty flavor. Most Italian greens have good nutritional value. They can contain vitamins A and C, folate and iron, usually have a multitude of antioxidants and some even contain quercetin, a natural antihistamine. They are generally used in salads and as soup garnishes. Most varieties of Italian lettuce can be grown indoors quite easily, although they grow best outdoors with full sun and partial shade throughout the day. To meet these lighting requirements indoors you can grow your lettuce under an array of high-output T5 fluorescent light bulbs.

You can also grow them under HID light bulbs as long as the bulbs are kept a fair distance away from the leaves, as lettuce tends to get leaf burn from the heat of the lights. Italian lettuce grown in soil or soilless mixes can tolerate a pH range of 5.6 to 7.5 but will do best in the pH six to 6.8 range. When grown in hydroponics, the ideal pH range is between six and 6.5. Harvesting the lettuce can be done a few leaves at a time or a whole plant at once, but by only taking a few leaves per plant you can allow your lettuce to continue growing and producing nutritious leaves. No Italian garden would be complete without at least one delicious herb. Although Genovese basil is one of the most commonly used herbs in Italian cuisine, like the tomato it was not native to Italy, but originated in India and was brought to Italy through the spice trade. Genovese basil—or sweet basil as it is more commonly known—is more aromatic than its Thai cousin and the oval leaves are broad, crinkled and green. Genovese basil is used in all kinds of Italian dishes as a seasoning, in pasta and pizza sauces and salad dressings, and it is the key ingredient in pesto sauce. Basil can be easily grown indoors and does well in soil or soilless mixes and various hydroponic media. It does well under an array of high-output T5 fluorescent light bulbs or under HID bulbs, and flourishes best when the pH range stays between 5.8 and 6.8 in soil or soilless mixes and between pH 5.8 and 6.6 in hydroponics. Genovese basil can be harvested fresh a few leaves at a time by pinching off the top of the branches and using the top leaves, causing the plant to become bushy and allowing more leaves to grow. Basil can also be harvested all at once and dried, preserving the leaves so that they can be used in recipes throughout the year. Hang the basil upside down in a dark dry place for several days—the leaves will retain their wonderful flavor best when dried in the dark. There are really too many great ingredients in Italian cuisine to mention more than a few in this short article. The examples we discussed are some of the most common, but there are so many other wonderful varieties that did not make the cut. Zucchini, beans, oregano, various tomato varieties and all sorts of other Italian vegetables, greens and herbs can all be grown indoors quite easily. Italian cuisine features a wealth of succulent and healthy ingredients, which makes starting an Italian garden a popular and rewarding choice for any home grower. MY Resources:

Forget conventional soil gardens planted in the earth or even indoor gardens on four by eight foot grow tables; up in the air is where gardening is at. The word vertical usually invokes a sense of up—and when it comes to sustainable farming for the future, up is exactly where some people think we need to go. The concept of vertical farming embraces much of what we know about green roofs and green walls, but it also goes far beyond those relatively smallscale upward movements. A vertical farm is more than just a wall or a roof repurposed for the growth and maintenance of plants; it is an entire building—preferably purpose-built from the ground up—designed to facilitate food production in a sustainable, environmentally sensitive way. The ideal vertical farm is a selfcontained structure with integrated agricultural systems, environmental controls, shipping and handling facilities,

laboratories and maybe even living quarters for the workers and a daycare center for their children.Vertical farms will not soon replace the traditional land-based farms that most of the world’s population currently depends on for its food supply, but they might have a lot to offer for the future. Much work needs to be done before vertical farming can become a viable option for mass food production in our cities—but if visionaries like Dickson Despommier have anything to say about it, another agricultural revolution might be happening sooner than anyone had previously thought possible. The viSion oF dickSon deSpoMMier Dickson D. Despommier is both a

microbiologist and what some might call a futurist. He has spent many years as a professor of environmental health sciences and as a professor of microbiology in the Columbia University College of Physicians and Surgeons in New York. He is also the world’s leading proponent of using vertical farming to address some of the planet’s most pressing problems: issues like world hunger, food security and the protection and healing of the environment. The vertical farming idea first came up in one of Dr. Despommier’s classes in 1999, during discussions about possible solutions to a wide range of environmental problems. Since then, he and 106 graduate students have continued to develop their ideas on how to

bring vertical farming out of the conceptual stage and into physical and economic reality. Although the vertical farming concept floated around without much fanfare for over a decade, it finally received widespread attention after Despommier decided it was time to write a book about it. Published in 2010, Despommier’s The Vertical Farm, Feeding the World in the 21st Century lays out a bold vision for what could be possible through the coordinated efforts of architects, scientists, governments and private industry. Conceptually, there is nothing unrealistic about the design and construction of vertical farms. Many of the technologies involved—such as hydroponics and aeroponics and automated control systems—as well as the advanced materials and energy conversion methods needed to make one work are already either already well developed or now on the verge of commercial viability. A vertical farm is much more than a hydroponic greenhouse erected in the middle of an urban landscape or attached to the

side of a city grocery store. Unlike a typical greenhouse, a vertical farm can be tall.Vertical farms offer many of the advantages of hydroponic greenhouses, such as reduced water use, year-round production and protection of crops from weather, but they can also make a major contribution to increasing the availability of locally grown food—with all its advantages— since they are designed to be located in areas of high population density. The Vertical Farm Website ( also lists many other potential benefits of vertical farming (VF), some of which include: • All VF food is grown organically: no herbicides, pesticides or fertilizers • VF virtually eliminates agricultural runoff by recycling black water • VF returns farmland to nature, restoring ecosystem functions and services • VF greatly reduces the incidence of many infectious diseases acquired at the agricultural interface • VF converts black and gray water into potable water by collecting evapo-transpiration • VF adds energy back to the grid via methane generation from composting non-edible parts of plants and animals 106

“things are changing rapidly and as of mid-2011 a number of impressive projects have already been constructed or are in the planning stages.”

VF dramatically reduces fossil fuel use—no tractors, plows or shipping • VF converts abandoned urban properties into food production centers • VF creates sustainable environments for urban centers When The Vertical Farm appeared in late 2010, Dr. Despommier knew of no large-scale vertical farms in existence anywhere in the world, but some people had clearly already started down that path. Since then, Dr. Despommier’s book and the ideas it contains have apparently struck a chord in many places around the world. “You can see that some countries get it,” says Dr. Despommier, adding “the architects of the world are on board, believe me.” Things are changing rapidly and as of mid-2011 a number of impressive projects have already been constructed or are in the planning stages. Let’s take a look at some of them: nuvege, inc. Nuvege ( is a company dedicated to advanced methods of food production. Their proprietary growing systems feature hydroponics, special lighting and carbon dioxide enrichment and they produce high-quality lettuce in commercial volumes. A major focus of the company is to produce food that has a very low bacterial load in order to reduce or eliminate altogether the incidence of food-borne illness. Although Nuvege is not in the vertical farm construction business, their systems are specially designed to be integrated into vertical farms. The company operates a facility in Kyoto, Japan to test and demonstrate their technologies that Dr. Despommier describes as being “747 hangar-sized.” “You are going to see a lot more development in Japan because of the Fukushima incident and the desire to protect agriculture from radiation,” predicts Dr. Despommier. planTlab This Dutch operation ( located in Den Bosch, The Netherlands, has been testing a prototype vertical farm for several years now and they are presently building a larger, completely enclosed (which means no natural light in the growing area) facility. Their approach is decidedly high-tech, incorporating custom-built growing environments, advanced automation and control and mathematical modeling of plant growth. The company claims that their use of specific wavelengths of red and 108

blue LED lighting results in better plant growth than can be achieved using natural light—according to Despommier, PlantLab believes that certain frequencies of natural light are actually inhibitory to plant growth. And vertical farms don’t necessarily have to go up; vertical implies down as well, and Plantlab is extending their newest facility several stories underground. Suwan, SouTh korea This facility, funded and operated by the government of South Korea, has been in full-blown lettuce production since March of 2011 and implements many of the ideas that Dr. Despommier describes in The Vertical Farm.

United Arab Emirates. Although no tangible results have been achieved in Canada yet, the governments of Surrey, Vancouver and Victoria in British Columbia have all released official statements in support of vertical farming. What about research and development? Certainly more needs to be done to improve existing designs, generate new design concepts and test and improve actual VF systems. Enter the University of Nottingham, UK. According to Dr. Despommier, a cadre of about 20 researchers, including professors and graduate students in the departments of biology and agriculture, have organized themselves into what might be called a ‘VF working group’. Their goal is to build a prototype VF and they are currently soliciting government funding for their proposed research. The vertical farm has a lot to offer and the concept has gained impressive traction since the appearance of The Vertical Farm, the posting of VF videos on YouTube and presentations by Dr. Despommier at prestigious venues around the world. Based on the rapid growth we are seeing today in the planning and construction of vertical farms, it probably won’t be long before tall buildings featuring futuristic designs—lush with greenery and bustling with activity—begin climbing into the world’s skies.

+++++++++++++++++++++++++++++++++++++++ In nature, the average CO2 proportion in the air comes close to 400 ppm (parts per million), and can largely vary depending on natural or manmade CO2 production. The air in the garden should be close to this concentration; below this limit, the photosynthesis and the growth considerably slow down and might even stop around 200 ppm or less. This situation might happen in an isolated indoor garden with no CO2 added. The plant will then consume the ambient CO2 until it’s all gone. The majority of plants will appreciate concentrations between 700 and 1,000 ppm during the daytime (light period) and around 400 ppm at nigh time (dark period).

the presence of light and therefore is useless, even harmful, in the dark period. In order to provide the plants with the optimal CO2 concentration for their growth, many gardeners turn toward CO2 enrichment. In addition to improving the yields, maintaining the recommended CO2 concentration in the air will also have the advantage of reducing the production time, accelerating flowering, improving the quality and the quantity of fruits and flowers, and may even diminish the incidence of some pathogenic fungus.

Not enough CO2 is harmful, but too much is just as bad. Equal or superior concentrations to 1,500 ppm are generally less effective and less profitable and can even have a negative effect on some crops. One of the most serious impacts is an overflow of CO2, which reduces the plant’s stomas opening, resulting in a reduction of the CO2 absorption and a limitation of transpiration. The transpiration is a key process for vegetal species because the water and nutrient absorption depends on it. Far from serving the plant’s interest, an excess in CO2 slows down the growth and, in some cases, can even cause leaves necrosis and curling or again provokes flower malformations. Tomatoes and cucumbers are particularly sensitive to high CO2 concentrations.

When choosing to enrich the garden with CO2, adjusting the garden’s temperature will be necessary. In fact, the optimal temperature for the plant’s growth increases by a few degrees (as much as 8º) when the air is enriched with CO2. Consider that the plant’s metabolism works faster when it benefits from a CO2 supplement; CO2 allows plants to produce better, but to do so, they need to consume more. Every need, like water and nutrients for example, will be increased. To fully take advantage of CO2 enrichment, we have to pay attention and take care of our plants to provide them with everything they need. MY

It is also the time to finish your notes for the season. Some people are blessed with superior memories and are able to recall each plant ever grown, back for years on end. For the rest of us though, detailed notes can be invaluable, especially when the time comes to plant next year’s garden. Gardening is an ongoing learning process. Over time, gardeners learn to refine techniques, select plants that do well in the available environment and estimate expected yields. Being able to quantify your results goes a long way toward determining if a given change is helping or hindering your quest for the maximum yield. One good way to figure out what to do when you’re planning what’s next for your garden is to take a look at what has worked—and what hasn’t—in past seasons. If careful notes are taken over a period of years, plants that perform well can be repeated. I’ve tried several different tomato varieties over the years, for instance, and two of my favorites are Black Crim and Big Rainbow. The first year that I grew them they were raised with several other different tomato cultivars, but by recording the names of the cultivars I tried that season I was able to avoid having to flip through pages and pages of seed catalogs looking for the right bluishmeated tomato and the right yellow one with red stripes the

following year. Another reason to keep a garden diary is to help keep track of when activities should be done. If the planting date is recorded and it becomes apparent in your harvest inventory that a plant was started too early or too late, the following year’s planting can be adjusted without havhav ing to rely on memory. If you’re fertilizing according to a weekly regimen, nutrient changes can also be scheduled in advance. Record keeping isn’t difficult once you get into the habit. A good garden record keeping program should include both plant labeling and a garden notebook. From the moment of purchase, plants should never be without a label of some sort. From seed to seedling tray, through planting, growing and harvest—each plant should be clearly identified. If seeds are saved, they should be marked so the cycle can

continue next season. Plant labels should be as waterproof as is practical; permanent markers on plastic stakes are a popular choice. A less thrifty option for those of us with questionable handwriting is to make use of a handheld label printer, which makes a very legible plastic label. The name of the plant (and the particular plant, if breeding) on the label is all that is required, since the rest of the plant information will be in your garden diary. When the plants are first started, make an entry in the diary with information about them. For example, you might record: 5/10/2011: Started tomato Big Rainbow from F1 saved seed indoors. Indeterminate, bushy, 90 days. Said to have rich smoky flavor. Expected harvest starting 8/10/2011. Then you’d record an entry on 8/10/2011—90 days later: Big Rainbow tomatoes ripe and ready for harvest. Flavor is rich and fruit is large and meaty. Exactly what information is recorded is up to the individual gardener. The garden notebook doesn’t have to be anything fancy; it just needs to be something to write notes in: a calendar, a dated logbook, a computer spreadsheet or even index cards will do. Depending on the size of the garden and the attention to detail shown by the gardener, weekly diaries can be a nice choice, as can spiral-bound notebooks. If enough space is left between the entries the same notebook can be used for multiple years, which provides the added

“if careful notes are taken over a period of years, plants that perform well can be repeated.” benefit of being able to see what was happening in the garden on the same day last year. For the more gadget-minded gardener, notes can be taken with a computer pad or laptop. With a reasonably simple database all the information one could care to collect can be stored with these devices and referred back to for a lifetime. If you do choose to make use of an electronic device to take garden notes, though, special care should be taken to avoid contact with water, mud, fertilizers, sap, juice or any of the other myriad of potential hazards that lurk in the garden.

prefer a good oldfashioned pen and paper diary, because I can leave it permanently stationed with my tools in the garden and if it gets dirty or wet I may swear a little, but I won’t actually cry over it—and if I were to spray my laptop with a garden hose, this might not be the case! Keep some blank space in the front or the back of the diary for more general, less date-specific observations and records such as equipment purchase dates and nutrient schedules. Keep records of the equipment you are using in your garden: the make, model, cost, purchase date and so on. Make sure to keep any receipts or warranty information in a safe place. Give each piece of equipment an identifying code or number—knowing exactly how many years a piece of equipment lasted can help with replacement purchase decisions and your records will show if a more expensive piece of equipment lasted longer than an inexpensive one, for example. Recording start dates for items that wear out over time can help budget for replacements. Indoor gardens require periodic bulb replacements, for example. When a new bulb is installed the replacement date can be noted in the diary in advance as a reminder—the gardener doesn’t have to remember how old a bulb is, they’ll come across the entry at replacement time. Always record major events that occur in the garden. Recording the appearance of first flowers when you start a new crop will give you a pretty good idea of when to expect the plants to start flowering next year. For indoor gardens, note any adjustments you make in the light cycle for photoperiod-sensitive plants. List

bug sightings, remedial measures, new equipment and seeds purchased. Log temperatures—especially heat waves or cold snaps. Gardeners experimenting with different nutrient and additive recipes can keep detailed logs of the products they apply and use the empirical information they gather to decide which is best. Baffling bug infestations need only be agonized over once—the solutions, once discovered, can be entered in the diary and guesswork will be a thing of the past. Written data can be augmented with photographs (especially useful when taken from the same angle and level of magnification) every week. These photos will illustrate how the current year’s plants compare with those from the previous season and with failed or bumper crops from past years.

As anyone who has ever overplanted zucchini can attest, knowing what sort of harvest to expect can influence how many of a particular plant to start. At harvest time, mark down which plants had a surplus and which ones came up short. To determine how efficiently you are growing your crops a simple formula can be used to determine the ounces gained per day. If Black Krim tomatoes were planted on 5/23/2011 and stopped producing on 9/23/2011, for instance, then the number of days between the two dates is 123. If 15 ounces of tomatoes were grown during this time, then the ounces grown per day

would be 0.12 ounces (or 15 divided by 123). Knowing this value can be handy when comparing seasons or the productivity of one cultivar with another. If all other factors are equal and using fertilizer brand ‘A’ results in growth of 0.10 ounces per day and using fertilizer brand ‘B’ results in .14 ounces per day, then serious consideration should be given to using brand ‘B’ on a regular basis. If one year a gardener uses soil pots and the next a hydroponic system, the data gathered in his diary can help him to choose which system he should use the followfollow ing year. One nice thing about keeping detailed records of this nature is that it will allow a gardener to compare plants started early with plants started late. Particularly in indoor gardens— where season length is artificially controlled—being able to compare seasons of differing lengths can be an asset in determining which conditions are the most productive. Your diary entries can be flowery and verbose or short and terse—even the most minimal entries can be learned from. If facts haven’t been recorded, though, once the particulars have faded from your memory they are gone forever. A good garden diary can bring a real sense of order and progress to your growing efforts.You won’t waste time trying things that didn’t work in the past and you’ll be able to easily access solutions that helped you with big problems in years gone by.Your garden diary isn’t just interesting reading material—it’s actual proof that you are becoming a better gardener with every passing year.

Bolting WHY DOES CILANTRO BOLT AND HOW CAN IT BE STOPPED? Cilantro bolting is one of the most frustrating things about this popular herb. Many gardeners ask, “Why does cilantro bolt?” and, “How can I keep cilantro from flowering?” By paying attention to the environment your cilantro grows in, you can help lengthen the amount of time before cilantro will bolt and, therefore, increase the amount of time you can harvest leaves from your plants.


Maximum Yield USA | October 2011


When gardeners see the white cilantro flowers, they wonder if they can simply cut them off. Unfortunately, once cilantro bolts, the leaves rapidly lose their flavor. Cutting the cilantro flowers off will not bring the flavor back to the leaves. Instead, let the cilantro flow flowers go to seed.The seeds of the cilantro plant are the spice coriander and can be used in Asian, Indian, Mexican and many other ethnic recipes. WHY DOES CILANTRO BOLT

Cilantro grows best in cool, moist conditions and will bolt rapidly in hot weather or a hot room. This is a survival mechanism for the cilantro plant. The plant knows that it will die in hot weather and will try to produce seeds as quickly as possible to ensure that the next generation of cilantro will survive and grow. HOW TO KEEP CILANTRO FROM BOLTING

The first thing to understand is that there is no true way to keep cilantro from bolting. Plants are designed to do one thing and that is to reproduce.You are fighting nature. But, there are several things you can do to significantly lengthen the time before the cilantro plant produces flowers: 1. If you’re growing in a warm environment, you can buy slow bolt cilantro. This is cilantro that has been bred to withstand higher temperatures. 2. No matter what kind of cilantro you grow, you should practice

succession planting. This is where you plant new seeds every one to two weeks so that as one set of cilantro plantings start to bolt, the next set will be ready to harvest. 3. If growing outdoors, plant cilantro during cool weather. Early spring, late summer and early fall are the best times to plant cilantro. If you plant in late spring to mid summer, your cilantro will bolt quickly in the heat. 4. Harvest your cilantro leaves frequently. The more you harvest your cilantro, the more likely you are to nip immature flowering stalks, which will delay cilantro flowering. 5. Mulch cilantro and plant it tightly. It is not the heat of the air that causes cilantro to bolt, but rather the heat of the soil. Mulch will help keep the soil cool and retain moisture. Planting cilantro tightly will shade the ground it grows in, which also helps to keep the soil cooler. For more gardening tips and tricks visit or check out

by Dr. J. Benton Jones, Jr.

A guide to the major four nutrient elements.

Tomato plants are considered heavy feeders, having a relatively high requirement for most of the essential plant nutrient elements. Based on this nutritional characteristic, tomatoes are frequently used as test plants for evaluating the nutritional quality and fertility status of growth media and for conducting plant nutrition studies. Not all growers are aware that the formulation of the Hoagland/Arnon nutrient solution was derived based on the elemental content found in the tomato plant. For the commercial production of tomato fruit, careful regulation of the essential plant nutrient elements—particularly the four major elements, nitrogen (N), potassium (K), calcium (Ca) and magnesium (Mg)—is essential in order to obtain high yields of quality fruit. Even though tomatoes are being grown around the world under a wide range of soil and climatic conditions, the same basic fertilizer recommendations apply. For commercial field production of tomatoes for both processing and the fresh market, N and K fertilizer rates are critical in determining fruit yield and for ensuring that the quality required for market acceptance is achieved from the judicial use 132

Maximum Yield USA | October 2011

of these two fertilizer elements. In addition, the soil ratio among the elements K, Ca and Mg, known as the Hartz ratio ( is frequently used to assess the probability for the occurrence of fruit color disorders in tomato fruit. For the hydroponic grower, including the home vegetable gardener growing in soil, let’s look at how these four major elements interact and affect tomato plant growth, as well as fruit yield and quality.

nitrogen (n) There exists a narrow range between deficiency and excess with this element, as N is required for vigorous vegetative plant growth, but in excess can promote vegetative instead of reproductive growth, reducing flower and fruit set as well as adversely affecting the quality of produced fruit. The tomato plant itself becomes more susceptible to disease and insect invasion as the N content of the plant increases. Supplying N to the plant as needed, in small aliquots sufficient

“the tomato plant itself becomes more susceptible to disease and insect invasion as the n content of the plant increases.�

to sustain good overall plant growth without stimulating excessive vegetative growth, is one way to minimize this potential. The form of plant-available N will also affect plant growth and fruit quality. In general, N absorption by plant roots is enhanced when there exists some ammonium (NH4) in the rooting media, which assists in maintaining the cation/anion

balance within the plant and minimizes the potential for nitrate accumulation in conductive plant tissues. The ammonium cation (NH4+) is a strong competitive cation, however, and can interfere with the root absorption and function of both the Ca2+ and Mg2+ cations, with this interference being most evident with the occurrence of blossom end rot (BER) in tomato fruit. Therefore, some recommend that ammoniumnitrogen be made available to the tomato plant during its vegetative growth period, but not during fruit set and development. In soil environments, unless

ammonium-nitrogen is being applied in irrigation water, it is usually easily and quickly nitrified to nitrate-nitrogen. My hydroponic experience would suggest that a NH4/NO3 nutrient solution ratio not greater than 1:10 is sufficient to sustain vigorous vegetative growth that should not result in the potential occurrence of BER in fruit. When growing tomato plants hydroponically, nutrient solutions that contain high levels of nitrate-nitrogen (NO3-N), will not only contribute to excessive vegetative growth but will also enhance the uptake of K in order to maintain the proper cation/anion balance within the plant. This can be illustrated using the standing-aerated hydroponic growing method by monitoring the change in the NO3 and K concentrations in solution when a vigorously growing tomato plant is placed into a minimum volume of a complete nutrient solution (one that contains all the essential elements). The concentration of both ions will decline in a relatively short period of time, while the other two essential major elements, Ca and Mg, will change little in that same time period.

potassium (K) This essential plant nutrient element correlates with fruit quality factors that affect flavor and acidity and is a factor that contributes to long-term keeping quality as well. The K+ ion is readily root-absorbed; therefore, its concentration in a nutrient solution can have a significant affect on the cation balance within the plant, interfering with the function of Ca and Mg. When K is in 134

attack oF the gargantuan tomato

excess it can induce a deficiency of either Ca or Mg—Mg more likely—even when there is sufficient Mg in the nutrient solution. Depending on the growing conditions, K supplied in small aliquots as needed, as is frequently done with N, would avoid the possibility of any K excess and the potential for induced Mg and Ca plant deficiency.

“Calcium deficiency is associated with the fruit disorder known as blossom end rot.”

Calcium (Ca) Calcium deficiency is associated with the fruit disorder known as blossom end rot (BER). Calcium is required for maintaining cellular integrity and when there is a deficiency of this element in a developing tomato fruit the cells at the blossom end will lack stability and cellular decay will occur, manifesting as dark or black discoloration at the blossom end. Although BER is the result of a lack of sufficient Ca—needed to maintain cellular integrity—the triggering mechanism is plant stress, usually moisture stress. The Ca2+ cation is not readily root-absorbed and its movement within the plant is in the transpiration stream. If the plant is under water stress or evapo-transpiration from leaf surfaces is low, the uptake and movement of Ca within the plant will be impaired, thereby increasing the potential for the occurrence of BER. To avoid or minimize its occurrence some recommend the application of a solution containing Ca on the plant foliage

The book describes how 6 different hydroponic growing systems work, the basis for the formulation and use of nutrient solutions, plus information on the basic principles of plant physiology that correlate with how plants can be grown hydroponically.

and the developing fruit. However, Ca is not easily absorbed through either the leaf or fruit cuticles—and even if absorbed, Ca will not easily move from the point of absorption since it primarily moves within the transpiration stream. Therefore, movement is up the plant, with little flow latterly or downward from one portion of the plant to another. To prevent or minimize the occurrence of BER, sufficient Ca must be available in the rooting medium as well as in proper balance among the major cations (K+ and Mg2+), including the ammonium cation (NH4+). It is also essential to ensure that those conditions that would result in plant stress—particularly moisture stress—be prevented.

Magnesium (Mg) This element is a component of the chlorophyll molecule and its plant physiology relates to those processes associated with photosynthesis, particularly energy-related functions. I classify tomato as an Mg-sensitive plant because its deficiency will affect fruit yield and quality in both soil and hydroponic growing systems. When Mg is deficient it can also be a factor in the development of BER in fruit since its deficiency creates stress within the plant, which then can become the trigger when insufficient amounts of Ca are present. The three cations K+, Ca2+ and Mg2+ are competitive cations, with Mg being the least competitive of the three and therefore more likely to be deficient than the other two even when the rooting media or nutrient solution formulation is considered to be sufficient in Mg. For hydroponic tomatoes I have increased the Mg content in the Hoagland/Arnon’s nutrient solution formulation by 50 per cent.

“to avoid or minimize [Ber] occurrence some recommend the application of a solution containing Ca on the plant foliage and the developing fruit.”

In my experience of observing greenhouse tomato enterprises, most tomato crops are deficient in Mg—even though plants may not be presenting any leaf symptoms. However, it is not unusual to observe such leaf symptoms on older leaves when the tomato plant is setting and maturing fruit. In order to prevent Mg deficiency, even when there are no visual leaf symptoms, the Mg content in

the rooting medium or nutrient solution formulation must be adequate to ensure that the Mg2+ cation is in sufficient concentration to compete with the other cations.

Conclusion Since tomato fruit production occurs over a fairly long period of time, growers should be monitoring—by means of pe-

riodic plant leaf analysis—the elemental status of the tomato plant, with the critical time periods being just before flowering and initial fruit set, and then again when the first fruits begin to mature. Any insufficiencies uncovered by the assay results can be corrected if the plants are being grown hydroponically, while plants being grown in a rooting medium that is being

periodically irrigated can be supplied through the irrigation water, with those elements in excess being withheld. Those situations where the assay results indicate an imbalance among the major elements can be difficult to correct if a supply already exists in the rooting medium, however. Some experts have suggested that beginning with minimum sufficiency levels in the rooting medium or nutrient solution will allow for relatively easy adjustment during plant growth and fruit set and maturity. There are various recommendations regarding what plant part to sample for analysis. My recommendation is to collect the end leaflet on a recently matured leaf, sampling at least 25 plants in order to obtain a representative sample. A whole leaf analysis can be difficult to interpret, since the whole leaf is a mix of stem, petiole and leaflet tissue—three tissue types that vary significantly in elemental content. And what about phosphorus (P), since it is also a major element and can significantly affect plant growth? Phosphorus deficiency is not common when growing tomatoes; in fact, its excess is far more common, since most fertilizer recommendations supply more than is needed and most nutrient solution formulations are also high in the element. High P will interfere with the plant function of zinc (Zn) and iron (Fe), frequently presenting as a slight chlorosis of newly emerging leaves, but with maturity the chlorosis will normally disappear. Chlorosis occurrence and the rate of disappearance are good indicators of the degree of P excess. Tomato plants are actually fairly tolerant of P in excess unless they are under stress caused by inadequate moisture, high light intensity or high air temperatures. Phosphorus root absorption is also affected by root medium temperature and declines sharply when the rooting temperature is less than that of the ambient air. MY 140

Manage MoisTure in The rooTs WiTh These key Tips Managing moisture levels is one of the most crucial factors to consider when it comes to getting the most out of your plants. Overwatering can cause a number of fungal and bacterial infections, which can lead to plant stress, stunted growth or even plant death. While some say that it’s not possible to overwater plants using hydroponic methods, this is not actually true—even in hydroponics plants are still susceptible to problems caused by too much water. 144

Maximum Yield USA | October 2011

Root rot is characterized by yellow leaves and plant wilting caused by waterlogged roots. While most issues related to overwatering occur in the root zone, problems can travel up to the crown and stems of plants, too. Prevention is key in these situations, because the healthier a plant is overall, the better able it is to resist infectious diseases of all kinds. The first rule in root rot prevention is exclusion, which means that the

pathogen (disease) organisms should be prevented from contacting your plants wherever possible. Pathogens often enter a grow room when plants are first brought into the environment from the outside. For this reason, purchasing clones from another grower who may have diseases or pests in his garden is often a risky practice—if root rot exists anywhere in his garden, spores could be present in the reservoir, which fed your

plants right before you purchased them. Fungal spores may lie dormant in water, infecting a weak plant within 15 minutes of exposure without revealing any symptoms until a week later. Another major factor in preventing root rot is providing adequate drainage. Regardless of which hydroponic medium you choose, it should drain well. Evaluate how long the medium holds water, then devise a watering schedule to best accommodate your plants: you should allow the root zone to dry to around 50 per cent or less before another watering or feeding occurs. The amount of time it takes roots to dry adequately will vary considerably, depending on the grow medium, the environmental conditions, the plant species—and even from plant to plant within your garden. To be safe, avoid scheduling feedings near the end of the daily light cycle.

root rot: the water management battle

“Many growers are able to successfully remove only the affected parts, but it is better to play it safe and remove the entire plant before it can infect the whole garden.” Roots should be the healthiest part of your plants and you should make an effort to examine them throughout their life cycle. While it may be difficult to observe the color of your roots depending on the specific hydro system you have chosen to employ, healthy roots are very visibly white. Although some nutrient solutions may darken the roots to a small degree, the rule of thumb is that the browner the roots are, the higher the risk of problems. If you can’t see the roots, then pay attention to the growth rate of the plants—if the rate slows drastically, obviously something is wrong. An easy way to track the growth rate is to use the simple and effective wooden dowel method: 1. Use a waterproof marker to mark one inch increments on the dowel.

root rot: the water management battle


Insert the dowel into the container with your pot and mark the plant height on the dowel rod. 3. At regular weekly intervals mark the plant height on the dowel. Now each week you should see a similar or greater increase in plant height until the plant begins to mature. Most growers will encounter the problem of root rot at some point. When it happens, there are a few things that can help control the outbreak. First and foremost, remove the infected plant! Many growers are able to successfully remove only the affected parts, but it is better to play it safe and remove the entire plant before it can infect the whole garden. Next, clean and disinfect walls, benches, floors and equipment with a mild bleach solution and let everything dry completely—fungal spores are transmitted through water and can survive in the smallest of water droplets. Finally, apply a fungicide to the remaining plants. There are many varieties of fungicides and some contain substantial amounts of heavy metals like copper or silver ions whether they possess the organic label or not, so be very cautious about applying them directly onto plants—particularly if any part of the plant is grown for consumption. Always read the entire label and follow the instructions exactly when using any pesticide, organic or not. When controlling root rot, any fungicide should be used as a drench (top watered) or run

through your irrigation system. Top watering is recommended for fungicides, as a bottom-feed system may not reach all areas where fungal spores exist. Now that you have done everything you can do, just wait and see if it works—sometimes infections are too far gone for you to be able to save the plants. In the meantime, learn what to do to prevent this problem recurring in the future. Reevaluate your watering schedule to determine if you could lower the frequency or duration of feedings without drying the plants out too much. Consider this: plants grow as the roots dry out. The process of using the water and nutrients they take up through the roots stimulates growth. Now think about your own body—it’s not the act of eating that grows muscles, but rather the exercise and burning of the calories in the food, which stimulates muscle growth. The idea here is that the more you allow plants to dry between feedings, the better they should grow. There is a point where too much dryness can cause unwanted stress or even kill the plant, so it is a bit of a balancing act, certainly.

“the more you allow plants to dry between feedings, the better they should grow.”

Automated Systems for a Worry-free Garden Winter in North America can reach freezing temperatures. For avid gardeners, hydroponics provides a welcome respite from the winter cold, as does a short vacation in a warm climate. To be able to do both would be utopia and I thought with today’s technology, there must be a way. An additional bonus would be to supply a second hobby, cooking, with fresh vegetables and herbs.

automated systems For a worry-Free garden

To achieve the degree of independence I wanted from day-to-day maintenance of my hydroponics system, I needed to: • • • • • •

Accommodate different nutrient mixes for different species at different stages of growth. Have flexible programmable timers for lights, pumps and fans. Have control over temperature and humidity. Use off-the-shelf hardware and plumbing components. Have comprehensive reports of system activities. Have e-mail notification of system activities, especially problem situations.

I decided to develop software for a control program, as there was none available with sufficient bells and whistles. The program evolved over a year or so and has now reached a stable state. Of course, enhancements are always being added. It’s the nature of engineering.

System Overview - The system has four building blocks: • • • • •

personal computer, software and USB enabled digital/ analog interface reservoir and nutrient pumping units lighting for seedlings and the main grow area fans, a humidifier and a heater grow units

Main: The main system status screen shows two of four active timers, the first of which is the HID light controlled by the stage of growth.

The SCP is the workhorse. It manages the nutrient mixing for up to four separate species groups and controls the grow room environment. The initial set-up included: tomatoes and peppers, chives, nasturtium and dill; basil and parsley, and sage; thyme and savory. This provided an opportunity to have the system take the tomatoes and peppers through growth, flower and final stages while maintaining the rest in growth only. The number of days for each growth stage was set and the nutrient mix calculated by the NOM was entered into the SCP. Timers are an integral part of a hydroponics system. Photoperiods for each stage of growth can be preset. HID lights are automatically synchronized to the preset period and can be turned on/off at specific times or be tied to sunrise/sunset. Seedlings are started in a small customized ebb and flow unit. A timer controls the T5 light period and a second controls the intermittent flood cycles. Choosing a growing medium and containers was a challenge. The first configuration consisted of four – 40 by nine by four inch trays. A cover for each tray was made with spaces for three

The tray contains three – 10 inch pots with 50/50 vermiculite/perlite. A delay can be set to provide air in roots to be refreshed.

I developed two programs. The first, a Nutrient Optimization Module (NOM), calculates an optimal nutrient mixing strategy for up to three stages of growth for a mix of species. Research suggested macro- and micronutrient strengths could vary considerably with species and growth stage. I gathered all the data I could on nutrient requirements for common species on the Internet. I then obtained nutrient constituent concentrations for various suppliers of one, two and three part formulas. A mathematical model in the NOM determines the optimal mixing strategy for the System Control Program (SCP) to administer. 156

Elements, left: This dialog shows the mixes added to lettuce, the concentrate of which was calculated with an estimate of the pH and EC based on previous measurements in the options nutrient dialog. Graph, below: Graphs are available for a wide range of parameters. Temperature for a four day period is shown here. Schedule, bottom: Each channel can have up to three growth stages specified. For each stage, the nutrient strength is provided along with the associated photoperiod.

– 10 inch pots. The pots were fitted with root guard in the bottom and filled with 50/50 perlite/vermiculite. In the bottom of the pot, a circle of porous tubing allows air to be pumped into the root zone. When full, the pots sit in nutrient about 1.5 inches above the bottom. Maintaining nutrient levels and concentration is the function of the nutrient mixing unit. The amount of nutrient required to maintain 1.5 inches above the bottom of the pots is approximately two quarts. When the level drops below the pot bottom, a time can be preset to allow full drainage and aeration of the roots in the pot before refilling the tray. When this time has passed, the reservoir pump fills a mixing chamber with two quarts

of basic nutrient. The basic nutrient formula is the minimum amount of each of the three parts required for all four channels. The flora micro component was a constant for all channels. Once the mixing vessel signals full to the SCP, two peristaltic pumps add any required make-up of grow and bloom. A solenoid opens and allows the mix to flow to the appropriate channel by gravity. Since the first run, I have used other grow units and will, no doubt, try other types. Deep water culture for lettuce and other leafy

veggies works very well. Future tests will be made with aeroponics and Ein-Gedi, a derivative of aeroponics that recirculates nutrient in a misty spray. No system is complete without reports and data gathering for later analysis. Graphs of temperature, humidity and nutrient usage are available. A log of all events associated with mixing, timers, and pumping can be viewed. The main screen provides a summary of current float, pump and solenoid states; grow room environment; and nutrient tank levels. For each refill, the concentration of macro and micronutrient constituents is calculated.

Results The 10 days of warmth during my holiday away from the winter was very welcome and no e-mails were received. The holiday was most relaxing knowing my hydroponics system was self-maintaining. Mixing the nutrients in small batches representing about 50 per cent of the total volume in the trays virtually eliminated the need to constantly deal with pH and TDS issues. All plants grew admirably. MY 158

Inside each seed is the magic of season’s past just waiting to be unleashed. Every time we preserve a seed, we preserve a little bit of that magic in the hope that it will show itself for years to come.

cleaning ing and drying: weT proceSSing

This method is used for seeds that are embedded in the flesh of fruits and berries. Depending on the spe-

“high TeMperaTureS can render good SeedS uSeleSS; high huMidiTy can allow MicroorganiSMS To grow and ruin SeedS.”

cies, the seeds, juice and flesh of the fruit will need to go through a fermentation process where bacteria or yeast will destroy many seedborne diseases that could affect the next generation. Seeds should be washed to remove them from the encasing flesh. An easy way to do this is to place the seed, juice or flesh mixture into a large pail or bowl containing double the water as the volume of seed/pulp mixture. Stir well and keep pouring off the dirty water, adding clean water and repeating until only clean seeds remain. Once the seeds are clean, they can be placed to dry on a non-stick surface, such as a cookie sheet. Do not use paper or any surface that the seeds might stick to. Also do not dry seeds in the sun, because temperatures exceeding 95°F will almost certainly guarantee the impotence of a seed. dry proceSSing and winnowing:

This technique is for plants that produce seeds in pods or husks, such as peas and beans. Gardeners must allow the pods or husks to dry with the seeds still inside. Once seedpods are dry they can be threshed, a process that frees the seeds by breaking their covering. This is typically done by rubbing or beating the pods until

the seeds are released. Place all the seedpods into a sac or pillowcase and rub your hands together until all the pods release their contents. Be careful not to get too rough with the seeds, because they can be damaged when rubbed or beaten too hard. The seeds must now be separated from the debris of pods and husks through a process called winnow winnowing. If there is wind, one simply picks up a handful of seeds and pod debris and drops it. The seeds, being heavier than the pod debris, should fall to the floor while the pod debris is blown away with the wind. Winnowing is repeated until all that is left are clean seeds. Another approach to winnowing is to use different sized screens to separate seeds. To perform the screen technique, gardeners first use a screen with holes large enough for the seeds to pass through. Then a second screen smaller than the seeds is used to filter out the remaining debris. labeling and SToring

High temperatures can render good seeds useless; high humidity can allow microorganisms to grow and ruin seeds. To avoid high humidity, only store dried seeds to five to 10 per cent moisture. All seeds should be placed in containers that are airtight. The ideal solution is to place dried seeds in a labeled envelope or Zip-loc bag and then place it into a Mason jar. The Mason jar or other airtight container should be stored in a place out of the sun where temperatures are not likely to fluctuate. An ideal storage place is a cold-room or root cellar. Note: If seeds are stored in a cold cellar for any longer than two years, the seeds will barely germinate and leave few survivors. There is a way to ensure your seeds thrive for five years or more. The way to achieve this is to freeze your seeds. Note: If seeds are not thoroughly dried, excess moisture will expand when frozen and destroy the seeds.

This will happen to seeds with more than eight per cent moisture. A sure way to tell if a seed is dry is to seal it in a jar with double its volume in silica gel for seven days. Silica gel beads are used by manufacturers to remove excess moisture and can be reused indefinitely. Simply dry the silica gel in an oven at 93°F for eight hours. After being sealed for seven days with the silica gel, the seeds should have just the right amount of moisture to be frozen safely. Another option is to test the seeds before freezing them by hitting a seed with a hammer or something heavy. If the seed shatters, it is dry enough. If the seed mashes, then they need to dry longer.

YOU TELL US MY: What is pyrethrum? Grigg: Pyrethrum is an extract from the oils found in the seeds of chrysanthemum flowers; once it is refined it makes pyrethrin.

Doktor Doom’s Grigg Kellock debunks some of the myths associated with pyrethrin-based products and details the benefits of this natural, earthfriendly product.

Grigg Kellock

Maximum Yield (MY): What products in the Doktor Doom line are you excited about right now? Grigg Kellock: The Doktor Doom one-two punch Spider Mite Knock Out elimination products. MY: What are your Spider Mite Knock Out products made of and used for? Grigg: Doktor Doom Spider Mite Knock Out is made with 0.20 per cent pyrethrin.This is a very strong concentration of pyrethrin. There is no Piperonyl butoxide in the product, which works as a synergist with pyrethrin.The pyrethrin knocks the bugs down and Piperonyl butoxide can be considered the knife in the back, while Doktor Doom’s Spider Mite Knock Out is the uppercut. Pyrethrin without the synergist Piperonyl butoxide is approved for organic gardening programs; refer to OMRI for the exact requirements. It is very important that people trying to eliminate spider mites use our one-two punch elimination program systematically, otherwise they will not get the results they are looking for and blame the products for not working when in fact it was misuse of the products that didn’t obtain the desired result. 164

Maximum Yield USA | October 2011

MY: How does pyrethrin work? Grigg: Pyrethrin excites the nervous system of insects and kills them on contact. Pyrethrin flushes out and drives insects to move as they know that if it contacts them they will die. Insects will lay eggs to procreate (when faced with certain death) so using the one-two punch elimination program does take time and effort to obtain maximum results. Pyrethrin does not kill larvae or eggs so repeated applications are extremely important. Refer to Doktor Doom Application Tips at MY: Are pyrethrin products ecofriendly and safe to be used around humans and animals? Grigg: Pyrethrin-based products are very environmentally friendly and safe to use around humans and pets. As these products are designed to kill insects it is very important to follow label instructions. These instructions are provided to protect humans and animals from any excessive exposure to the products. Pyrethrin biologically dissipates into the environment in a matter of hours after being exposed to light, air and humidity, and has zero residual activity.

MY: What can Maximum Yield readers expect from Doktor Doom in the near future? Grigg: Doktor Doom will be introducing some organic fertilizers that we have been testing for a couple of years.We have been working closely with the government to substantiate any claims that may come with these products. Doktor Doom has built its reputation on high quality products that work so one thing is for sure, do not expect us to market products that don’t meet our standards!

MY: What other products do you offer in North America that growers will be excited about? Grigg: Doktor Doom is working on a couple of other insecticide products to help growers eliminate all sorts of other insects in addition to spider mites. Our existing products are also excellent for controlling thrips and other plant-eating insects found in gardens. MY: What are your Total Release Foggers product made of and used for? Grigg: Doktor Doom Total Release Foggers are made with .40 per cent pyrethrin and 2.0 per cent Piperonyl butoxide.The Doktor Doom Foggers are part two of the Doktor Doom onetwo punch elimination program.The foggers should be used after an application of Doktor Doom Spider Mite Knock Out has been applied to the underside of the plant canopy.This initial application of Spider Mite Knock Out will not only kill all the insects (not the eggs or larvae though) on the underside of the canopy, but will also make the insects move to the upper surfaces of the plant canopy; this is where the Total Release Fogger comes in as the overhead bomb and wipes out all the living insects that crawled away from the initial uppercut application of Spider Mite Knock Out. MY: What food crops can fogger be used on? Grigg: Doktor Doom Total Release Foggers are safe to use on all food crops up to three days before harvest. Doktor Doom Spider Mite Knockout can be used up to the day of harvest.

MY: How does Doktor Doom support local causes and community building? Grigg: Doktor Doom supports several non-profit charities locally in Edmonton, Alberta, Canada that feed, cloth and shelter children, the disabled and adults that are in need. We also support our local Cross Cancer Hospital as we have all been touched by this terrible disease. In addition to this, my wife Philippa and I also volunteer for another local non-profit charity that provides children in inner city schools with a hot breakfast and helps to provide formal wear to youth that would otherwise not attend their prom. We also volunteer for the Edmonton Folk Music Festival, which provides all sorts of people the ability to afford to go and see great music.

MY: What strategies has Doktor Doom implemented to lessen their environmental impact on our planet? Grigg: We started our company promoting and marketing environmentally friendly and earth safe insect control products. Since the inception of Doktor Doom several governments and countries have banned all sorts of harsh chemicals. This includes the EPA and Health Canada. Doktor Doom is going to continue to educate people on the pros of using pyrethrinbased products. We firmly believe that these are the most effective products with the least amount of environmental impact available to consumers today.

MY: Where can growers go for educational materials on using your products and to learn more about your company? Grigg: Our website has application tip sheets on how to use our products. We refer people to these application tips daily; it is very important to read and practice what you have read to obtain maximum results from using our products. These product application tip sheets are also available from our wholesalers and should be available in most indoor garden centers. MY Maximum Yield USA | October 2011

Rio and Jeanette’s three-year-old son Wylde adds an element of fun and play to the store’s atmosphere as he frequently interacts with customers.

At A GLAnCe Company: roots Grow Supply Owners: Shawn Johnson and rio finds the feather Location: 1330 n. Hulbert #101 fresno, California Phone: 1-559-840-0122 Web:

In the heart of one of the agricultural capitals of the world, Shawn Johnson and Rio Finds The Feather opened Roots Grow Supply. The intention was to provide Fresno, California and the Central Valley with a hydroponics and indoor gardening store with long hours, exceptional customer service and a fully stocked warehouse teaming with products. Since opening, Roots has had to move to a new location twice the size of the original 3,000 square foot space to accommodate the growing demand for indoor gardening supplies. A second warehouse was also opened in Oakhurst, California. Having to compete with well established nurseries, commercial farming supply stores, corporate hardware stores with gardening centers and a handful of established hydroponics stores in the area, Roots had to set themselves apart to gain an edge. “In this business being progressive is the name of the game,” Shawn explains. “This industry is perpetually advancing in technology and we want to do the same on the retail end both in our advertising and customer service.”

Motto: “for growers by growers.”

Roots Grow Supply is more than just a product supermarket. Extraordinary growth decorates the shop inside and out, serving as demonstration gardens for customers to learn from.

An impressiv e sunflower display, which beauty, ador includes an 11 ns the shop’s foot frontage.

Gardeners of all experience levels come into Roots Grow Supply, from beginners to seasoned veterans and everything in between, with a myriad of questions ranging from the difference between organic and synthetic nutrients to how hydroponics work. Shawn and Rio are both experienced growers and have come up with a few ways to help their customers better understand the products they carry. Running side-by-side comparisons on tomato plants with different nutrients, the shop’s own blend of compost tea and a control of reverse osmosis water allows people to see first-hand how different nutrients perform. One of the more noticeable displays is the sunflowers in front of the shop. In one 45 gallon pot you see an 11 foot tall sunflower; in a seven gallon pot next to it much smaller sunflowers are growing.The shop also offers free cloning classes that walk customers through the process. “People are much more inclined to believe what they see,” Shawn says. “I can explain how something works for hours, but once a person sees what the product does they understand it immediately.” Roots has a working ebb and grow display with tomato plants, green beans and peppers growing in it.They also have a clear EZClone that shows how a cloning machine works from a mechanical standpoint as well as a Turbo Klone display that shows how the machine works on cuttings throughout the cloning process. With so much agriculture in California’s Central Valley, pests are in abundance; everything from white flies and root gnats, to caterpillars and spidermites. It’s not uncommon to hear customers asking for a wide variety of pesticides, some legal and others not. Many of our customers grow edible plant for human consumption and it can be difficult to explain the reasons for avoiding some of these pesticides while a customer’s crop is being ravaged by pests. However, Roots always recommends safe and natural alternatives. They carry 100 per cent vegetable-based pest solutions as well as beneficial insects such as spidermite predators, green lace wings, ladybugs and nematodes.

The staff at Roots likes to keep things fun and laid back. Joe, Mike and Casey-John make up the rest of the staff at Roots and are all musicians.The guys like to play all types of music; hip-hop, country, heavy metal, reggae, funk and mariachi that you can hear throughout the store and through the speakers in the front playing to the plants. It’s not uncommon to walk into the shop and see someone riding a skateboard from one side of the shop to the other to fill dead hours and take a few minutes to unwind. Once a year the shop celebrates its anniversary by putting on a free barbecue, with live entertainment and a bounce house for the kids. Rio’s family—that includes his girlfriend Jeanette, their one-year-old son Legend and three-year-old son Wylde—love these celebrations and Wylde can be seen weaving through the attendees on his tricycle. All of the staff is excited to learn new things. “It’s great to watch our customers grow over time. One day we’re explaining basics like transplanting, then a few months later they’re coming in telling us stuff they figured out and that we have to try,” says Shawn. Being in such an ag-minded community gives them a wealth of opportunities to gain knowledge from all types of growers raising vegetables, almond orchards, vineyards and so much more. They also look forward to attending the Maximum Yield Indoor Gardening Expos. After being open a little under two years Roots Grow Supply has taken off and Shawn and Rio‘s vision of an indoor gardening store with a massive inventory has come to fruition. “It definitely wasn’t easy being the new kid on the block,” says Shawn, “but now we have customers comparing us to other heavyweight indoor gardening stores in the San Francisco area and that is an awesome feeling.” As far as the future is concerned, Shawn and Rio believe that as the market grows so will Roots and they’ll continue to make the heart of California a little more green.

It was once believed that the oxygen released from photosynthesis came from the breakdown of carbon dioxide.



pushing EC in the root zone to much higher levels than we would normally use for leafy herbs reduces the amount of water taken up by the plant and held in the foliage, thus allowing their scented oils to become more concentrated.
