LETTERS TO the editor Opposing View Dr. J. Benton Jones’ article “What Should We Know About Biological Inoculants?” (February 2011), is spot on, but only if you are willing to pretend that decomposition is the only task accomplished by biological activity in the rhizosphere. Unfortunately it’s not. Other far more vital functions of fungi and bacteria are nutrient fixing, nitrogen cycling (nitrate/nitrite), nutrient transport and “cracking” natural potassium compounds to make them available. Even if all an organism does is eat and reproduce and excrete, it is participating in vital soil and rhizosphere activity. Not all of this is strictly related to decomposition, though it is driven by the activity of the organism. I would direct readers to a series of lectures given by Dr. Elaine Ingham and Carole Ann Rollins, PhD entitled “Adding Biology for Soil and Hydroponic Systems,” published by the Sustainable Studies Institute, Corvallis, OR. As to competition with the subject plant for soil resources, in good organic practice, one feeds the organisms that by their activity feed the plant, so “competition” for resources isn’t what is happening at all. Only if you must persist in the idea that you are feeding the plant by fertilizing in an organic system does this assertion make sense. Ideally you are not; you are feeding the natural nutrient cycling of the soil. If all components of the soil are adequate, there should be no need to add any fertilizer to the system at all. In the natural world everything has its place. I disagree with Dr. Jones’ assertions. Anonymous

In the recent article, “Why should I care about by Charlen e Rennick pH?” there are some Have you misleading statements. ever wond “p” in “p ered why H” the while the is a lower-case let “H ter Although hydrogen is an does it me ” is capitalized? What an? essential plant nutrient element, pH has no direct relationship to the hydrogen nutritional status of a plant. The pH of the rooting medium— whether a nutrient solution or a material substance (organic or inorganic)— does affect the ionic conditions that surround the plant root and ion absorption, the optimum pH being on the acidic side between pH 5.8 and 6.4. Actually the rhizosphere around the plant root is very acidic, in the range between 4.5 and 5.5, the acidity coming from the hydrogen ions generated by root respiration. Water is not primarily root absorbed by osmosis, but is drawn into the root by the “pull” created by the transpiration stream. As water is evaporated from leaf surfaces via transpiration, the water column that exists in the xylem vessels in the entire plant, provides the “force” that pulls water into the root. Some ions that are in the water surrounding the root are also drawn in, although most ions are selectivity absorbed. There is no such thing as “hydrogen osmosis.” The hydrogen that is required by plants is derived from root absorbed water. In the process of photosynthesis, a water molecule is split, the hydrogen atom released combined with a molecule of carbon dioxide to form a carbohydrate molecule, and in this process, a molecule of oxygen is released into the atmosphere. Osmosis is the movement of water through a semi-permeable membrane into a region of higher solute concentration. Osmosis only occurs in the so-called “free space” that exists in root tissues. The ability of ions to move through the root membrane against a concentration gradient from the solution surrounding the root into the plant root requires energy that is obtained from root respiration. This is why plant root function requires that the surrounding root environment be aerobic. Reverse osmosis devices generate pure water by passing water through a series of membranes that strip ions and molecules from the water. Reverse osmosis devices are very efficient in removing all dissolved substances as well as some small suspended molecular substances. Therefore, the additional need to pass RO-generated water through an activated carbon filter is usually not necessary. “The leve l of pH is measured of zero to on a 14 highest con with zero represent scale ing centration represent of acid and the ative of the 14 most alka line.”

SIMON says

Simon, Is crop rotation important in hydroponics? What are the most common issues or pests that the serious home hydroponic grower might face when using this technique? Thanks, Stevan

For centuries people have been using crop rotation when producing agricultural crops. Even today, rotation is recommended as a great method for the backyard gardener producing food for the family. There are several reasons to practice crop rotation. On a commercial scale, things like economics, commodity prices and sometimes water use can be determining factors, although for the home gardener, these aren’t the likely reasons. Cycling of crops to avoid pests and disease is another function of rotation that benefits home and commercial growers alike. This is a tremendous benefit to annual food production, compared to perennial systems where you can move crops away from a problem and restart. Nutritional needs are also an interesting reason to keep the flow of crops dynamic. Some plants feed very heavily, some lightly; others can actually renew fertilizer values in soils. One example would be legumes, which associate with nitrogen fixing bacteria for a net positive benefit of N in the soil at the end of the crop. This shows another possible benefit of modifying or enhancing soil biology and in turn, soil quality. The last benefit is related to the use of different plant’s root growth to change soils texture. As you can see, there are a variety of reasons for crop rotation. How does this relate to hydroponics, and is it important? My first impression is that it is hard to see any of these benefits being important in a hobby 20

hydroponic system. However, the rotation to reduce disease and insect pressure could come into play, which brings us to the second question. Greenhouse growers and indoor gardeners have similar issues when it comes to pests. At the core of the issue is the artificial environment, which in many cases can be useful to the horticulturalist but in the case of pest pressure is an Achilles heel. Without the balance of a natural system, when something detrimental infiltrates the system, the spread can be shockingly quick without the biological balance of

“If...production managers are choosing biological, it is not because they are feeling warm and fuzzy about the environment.” the outside world. Those of us that have seen powdery mildew or mites move through gardens know how vigilant the grower must be. There is no substitute for the observational diligence of the grower managing any pest-related issue quickly and effectively. The most common issues will be regional and also directly related to the plants being grown. As always, I defer to the local shop as the authority on local problems and the solutions they have found to be effective. Air intake into the grow room is a major source of contamination and there are now products available to

reduce this possibility by filtering the intake air. Remember that movement of people in and out of the grow room is probably the second most common contamination source, so be aware of this vector as well. Looking at the commercial greenhouse system in North America we can use their incredible research to really look at the most cost effective solutions, albeit on a commercial scale. Because of the contained artificial environment, the use of pesticides has always had a major role, and chemical pesticides still have a strong presence in the market. Attending commercial shows and browsing industry magazines I have observed a tremendous shift to biological solutions. With the lean margins in greenhouse vegetable production, if these production managers are choosing biological, it is not because they are feeling warm and fuzzy about the environment. It’s because those parasitic wasps or predatory nematodes are functioning to a higher level that the chemical option and can be a more effective solution to keep their systems running at the highest efficiency possible. Keep this in mind and see if your local shop has some biological solutions the next time you visit. MY Do you have a question for Simon?

Vanilla: Preserving a World Favorite Flavor Vanilla is one of the world’s best-loved flavors, second only to chocolate; it’s also the second most expensive spice after saffron, and demand for it is increasing all the time. Highly labor intensive cultivation methods and the plant’s temperamental lifecycle and propagation mean production on a global scale is struggling to keep up with the increasing demand for the product. But now its future in the global food industry could be more secure, thanks to research at The University of Nottingham’s Malaysia campus (UNMC). Scientists at UNMC are working to create new and robust methods for the cloning of some economic species and some rare species of the orchid through tissue culture. Tissue culture or cloning of a high quality parent plant from somatic cells offers a viable and simple method for the large scale commercial production of vanilla plants.

Fish Farm Waste Can Drift to Distant Shores Concentrated waste plumes from fish farms—dissolved substances from feces, undigested food and other forms of discharge—doesn’t dilute immediately and could travel significant distances to reach coastlines, according to a new study from the Woods Institute for the Environment at Stanford University. The paper is the first detailed look at how ‘real world’ variables, such as tides, currents, Earth’s rotation and the physical structure of the pens themselves, influence the flow of waste from fish farms. The research can serve as an important tool for determining the impacts of aquaculture discharge on waterways and surrounding shorelines. The findings suggest that regulators need to consider the full range of possible influences on the movement of pollution plumes—and accurately identify the dominant factors—when designing water quality regulations for and monitoring waste from aquaculture.

In Paris, two companies, Pons and Huot, share one of the more remarkable offices in the city. “Forest Through the Table” is the result of a renovation of an old industrial workshop. Taking advantage of the wide spaces and high ceiling, a self-cleaning glass roof was installed to bring in tons of sunlight. The office is set on top of a solid oak platform into which each individual workspace it cut, and then topped with a Plexiglass dome. Visitors are guided by a “peripheral path-system” that leads them where they need to go. (Source: www.treehugger.com)

Biological Control: Past Progress, Present Knowledge, Future Forecast by Donald Lester

Biological control agents (BCAs) are environmentally friendly, cost-effective and stable, and the benefits don’t stop there. Read on to learn all about this eco pest control strategy and how they can help lessen our dependence on chemicals in the garden.

Biological Control

“The Egyptians were so impressed with cats that they deemed them gods.“ The earliest known written record of using one organism to control the population of another was the use of cats for the control of rodents in food stores in ancient Egypt around 3,000 BC.The Egyptians were so impressed with cats that they deemed them gods. Biological Control is a term that was coined by University of California professor Harry Smith in 1919. Currently, in terms of agriculture, the USDA defines biological control as “The involvement of the use of beneficial micro-organisms, such as specialized fungi and bacteria, to attack and control plant pathogens and the diseases they cause.” Beneficial micro-organisms that fit this definition are also known as biological control agents (BCAs). There are over 300 commercially available BCAs on the market today for controlling insects, nematodes, fungi, bacteria, weeds and other pests.The most successful commercial BCA is Bacillus thuringiensis used for insect control. Annual sales of Bacillus thuringiensis worldwide averaged $100 million in the year 2000. During the past few decades BCAs have been developed for use on soil pathogens.This presentation will discuss four BCAs that have been used in greenhouse and soilless hydroponic systems to control soil pathogens: Bacillus subtilis,Trichoderma sp., Pseudomonas sp. and

Maximum Yield USA | June 2011

Mycorrhizal fungi.This article briefly covers how biological control was perceived in the past, how trends in today’s world influence how BCAs are viewed and the factors and trends in the marketplace that are driving the increased use of BCs into the future.

Past

In the past few decades biological control has been viewed as the Egyptians viewed it—one organism to keep the population of another organism in check. And like the Egyptians with the cats, BCAs in the last few decades were expected to be self-sustaining with no maintenance required.This natural phenomenon of pest population regulation gave rise to the ecological basis of integrated pest management (IPM) strategies. Biological control was viewed as a self-sustaining component in an IPM program. There are four mechanisms that biological control agents use to control pests and pathogens: direct competition, antibiosis or antagonism of pest populations, parasitism and inducement of the plant immune system. In the past, competition with detrimental micro-organisms was the main mode of action. Biological control fell out of favor because of problems with unrealistic expectations. One problem with BCAs was poor formulation. Not too many years ago BCAs often had to be shipped in refrigerated coolers or on dry ice, which lent to a very short shelf life.This made usage difficult and the results unpredictable. Besides high expectations, low efficacy, relatively low cost and widespread availability of conventional chemicals and insufficient knowledge of the biology of BCAs and pathogens all led to a decline in the use of BCAs.

Maximum Yield USA | June 2011

Biological Control

Present

Today much more is known about BCAs. Biological control is considered a mature science. Research has generated a wealth of information on how BCAs impact plant disease. In the past 20 years there have been some 5,000 articles published in revered journals, and over 50,000 popular articles covering the subject. Advances in computing, molecular biology, analytical chemistry and statistics have led to new research aimed at understanding the pathogens, host plants and biological control organisms on many levels. Advances in formulation now make it possible for manufacturers to offer BCAs in easy-to-use liquid and granular formulations with shelf lives of up to two years in some cases.

“Modern chemistry equipment can detect chemicals at far lower concentrations than machines just 20 years ago.”

There is also an increased reluctance to use conventional chemicals. In fact, it is said that chemistry sets today do not even come with chemicals anymore due to legal liability. Add to this the fact that modern chemistry equipment can detect chemicals at far lower concentrations than machines just 20 years ago. Now with residues recorded where none had previously existed (values used to be recorded as below detectable limits) consumers see the world as becoming more polluted.They view any amount of chemical residue as too much, especially with the long term negative effects of many chemicals becoming so prominent in the news. One publication adding to the avoidance of conventional chemicals is the “Shoppers Guide to the Dirty Dozen” list.This list was compiled by the Environmental Watch Group using U.S. government data from 2000-2007 to rank which fruits and vegetables had the highest amounts of pesticide residues. All of these factors are paving the way for organic foods to enter the marketplace, which command a premium price and reduce the use of conventional chemicals.

Moreover, additional benefits of using BCAs have been identified: • no minimum residue limits (MRLs) • no withholding periods • proven efficacy • IPM friendly and environmentally friendly • safer to use, reduced liability • cost-effective • reduces risk of pathogen resistance buildup • BCAs more stable than chemical pesticides • non-phytotoxic • improvements in overall crop health and yield • number of organic growers increasing • no toxic waste disposal problems However, there are still some factors that limit the effectiveness of BCAs. They are living organisms and suffer from the same environmental pressures that mankind do: weather, 50

Biological Control

temperature, moisture content of soil or media, pH, disease pressure, timing of application, storage and handling and competition from native micro-organisms. But, with proper education growers have been able to successfully employ BCAs in commercial operations with excellent results. Rather than the old one-on-one model—one BCA for one pathogen—manufacturers and researchers are using combinations of BCA organisms to increase target spectrums or increase the length of time a control may be effective. This new concept fits in well with the goals of IPM and increases the efficacy of BCAs adding to their credibility.

Biological Control in Greenhouses and Hydroponic Systems

Over the years research has shown that BCAs have the capacity to be curative rather than just preventative. Several research studies show good control of several common greenhouse and hydroponic pathogens. Lettuce has several key pathogens: Pythium, Botrytis and Phytophthora. Studies have shown that Pseudomonas and Bacillus subtilis effectively control these pathogens (Card, et al. 2002, Boshoff 2006). Cucumbers have a slightly larger set of pathogens than lettuce. Pythium has been effectively controlled with Bacillus subtilise (Utkhede, Koch, and Menzies 1999). Trichoderma and Pseudomonas putida have been shown to control several root, crown and foot rots in tomatoes. And Bacillus subtilis is effective in controlling powdery mildew (Sivan and Chet. 1993, Kamilova, Validov and Lugtenberg 2009, Latunde-Dada 1993). Cut flowers benefit from BCAs as well. Trichoderma was shown to control Botrytus gray mould. Pseudomonas and Bacillus subtilis are strong candidates for control in hydroponic chrysanthemums. (Elad 1993, Orlikowski 1995, Liu et al. 2007).

Future

Trends show that BCAs are in our future. Surveys of both conventional and organic growers indicate an increasing interest in using biological control products. In fact, many conventional growers use softer chemistries when they can. One wine grape grower told me that his decision to switch from conventional chemicals to more organic materials was influenced by the 52

Maximum Yield USA | June 2011

complaints he was receiving from his customers about odors in the tasting room. This got him thinking and he was stricken by the realization that his grandchildren play in his vineyard. Trends also show that chemicals will continue to be banned. Europe banned 22 chemicals in 2008 and six more in 2009. The U.S. Environmental Protection Agency (EPA) is constantly reducing the amount of methyl bromide soil fumigant used every year as well. Furthermore, the cost is always increasing to register conventional chemicals. The growing organics market and increased public awareness of the environment add to the pressures against chemicals. BCAs will not replace conventional chemicals but they will certainly play a role in filling in the vacuum as conventional chemicals disappear.

“Would you rather see your workers applying a safe product or would you rather see them in a moon suit?“ Besides market trends there are other factors driving the growth in BCAs: organic crop premiums, IPM, worker safety and liability costs, residue management and resistance management. Organic crop premiums induce growers to reduce their chemical inputs. Integrated pest management also stresses reduced chemical usage. The costs associated with worker safety and liability is far greater than using comparatively safe biological products. Would you rather see your workers applying a safe product or would you rather see them in a moon suit? Increased fertilizer and nutrient costs have growers looking at biological agents to break down their crop residues to free up expensive nutrients naturally. And BCAs don’t have the resistance buildup phenomenon that conventional chemicals do. So, who is saying this? The greenies? The environmentalists? No, the agricultural chemical industry (Farm Chemicals International, July 2008). BCAs still have their limitations with environmental factors and sometimes narrow usage conditions, but it is expected that improvements in formulation technology, advancements in biotechnology and increased understanding of micro-organism physiology—over time—will remove the guesswork and specialized education needed to get the full benefit of BCAs. This increase in biological knowledge will no doubt lead to advances in formulation that will take the guesswork out of application timing, worries about pH levels, temperatures and other environmental variables. So, the trend is for chemical usage to decline because of the factors I have outlined. And as IPM becomes the central strategy in pest control, it makes sense that BCAs will continue to grow in use and popularity as we move forward. MY Maximum Yield USA | June 2011

Oxygenate, Respirate or Suffocate by Dr. Lynette Morgan

All plants need oxygen for proper functioning and health. Oxygen starvation can result in myriad crises in the garden that can’t be reversed. So, how do you know if your plants are starved for oxygen? Pay attention.

Oxygen is a somewhat overlooked element when it comes to the essential plant nutrients. While we focus on nitrogen-to-potassium ratios, calcium-boosting formulations, optimal EC and carbon dioxide enrichment, the roots of our plants can be quietly suffocating, unseen and forgotten. Although photosynthesis is often seen as the process that drives plant growth and determines yields, there is another equally important energyproduction process taking place in the root zone—respiration. Respiration is a process in the root tissues that releases metabolic energy, which is required to fuel root growth, nutrient and water absorption and root cell functioning. If oxygen is in short supply the roots begin to suffocate, root growth slows or stops and there can even be a net loss of nutrient ions from the root system under anaerobic conditions.

Maximum Yield USA | June 2011

Oxygenate, Respirate or Suffocate

Why do plants need all this oxygen? In many hydroponic systems we like to think that oxygen in the root zone is always in plentiful supply; after all, soilless productions are supposed to eliminate all those ‘soil problems’ such as compaction, waterlogging and poor physical properties of the substrate. Many growers also factor in some form of oxygenation in their nutrient reservoir or system, either with nutrient fountains, fall-back cascades into the solution or air pumps, but is it really enough? The problem with root zone oxygenation in many hydroponic systems has as much to do with oxygen demand by the plants as with supply. Large healthy plants grown in a limited root zone such as a growing slab, bag or channel amass a huge surface area of root tissue in a relatively small volume. This—combined with the fact that indoor gardens can provide perfect growing conditions, plenty of warmth, optimal water and nutrients—means that the rapidly developing mature plants that develop can have an incredible demand for oxygen in the somewhat limited root zone they are grown in. We then need to consider the fact that even a highly aerated nutrient solution can only normally carry around seven to eight ppm at 68 to 88°F, and the potential of oxygen suffocation becomes apparent. A mature hydroponically grown tomato plant at optimal temperatures has a requirement for oxygen of 46 milligrams per plant per hour at 68°F, and this increases to 184 milligrams per plant per hour at 86°F. Warmer temperatures, increase the rate of root respiration dramatically. Furthermore, microbial life in the root zone also requires oxygen for growth and development and in some systems this can also have an impact. Of course, in a standard substrate-based hydroponic system the plant root system is not just dependent on oxygen dissolved in the nutrient solution for respiration; oxygen is also present in the air-filled pores of the growing media. As nutrient is applied and flows through the growing media and then drains from the base, fresh air is pulled down into the 58

root zone and fills the pores around the roots. Provided the media is permitted to actually fully drain and is not continually—or too frequently—irrigated with nutrient solution, air will remain in these pore spaces to provide some oxygen to the root system. These air-filled pores require replenishment on a frequent basis, however, as the high volume of root tissue absorbs oxygen rapidly. Here is where many inexperienced hydroponic growers run into problems with root zone oxygenation and suffocation. Some growing substrates naturally drain freely and hold a lot of air; chunky grades of perlite are one example. Some substrates, though— most often those which are composed of organic material which is still in the decomposition phase—can pack down and eliminate many of the air-filled pores which provide vital oxygenation to the root zone. Many hydroponic substrates are designed to be able to both absorb and hold moisture between irrigations and also to have a good air-filled porosity; however, if these types of substrates are irrigated too frequently, they can still become oversaturated, a process which robs the root zone of valuable oxygen supplies.

What does root suffocation look like? A lack of oxygen in the root zone causing root suffocation is not always easy to identify. Often the first sign under warmer growing conditions is midday wilting of the foliage, even when the growing media is fully irrigated. Unfortunately midday wilting can also have other

causes, such as a high EC, root death due to damage, chemical contamination of the water or recent transplanting. Many growers simply assume a wilting plant has insufficient moisture in the root zone and apply more irrigation—this is a disaster for an over-irrigated crop that’s already suffering oxygen depletion, as waterlogging excludes even more air from around the root zone. Under prolonged oxygen starvation, most commonly seen in waterlogged hydroponic crops, plants produce a stress hormone—ethylene—which accumulates in the roots. If oxygen starvation goes on for long enough, ethylene will also start to be produced in the shoots of

Lack of oxygen in the root zone predisposes plants to attack by root rot pathogens such as Pythium.

the plant, causing leaf epinasty. Epinasty is a downward curvature of the plant’s leaves, resulting in plants that look wilted but are otherwise turgid. If oxygen starvation continues and is severe, eventually leaf chlorosis (yellowing) and premature leaf and flower abscission will occur. In cases that are not so severe, plants such as tomatoes may produce adventitious roots on the lower stem and present swelling at the base. This is the plant’s attempt to survive in less than ideal conditions, and the symptoms have caused many inexperienced growers to enquire about strange ‘bumpy stems’ on their tomato plants.

Oxygen and root disease Sufficient levels of oxygen in the root zone are essential for healthy roots, which are the first line of defence against many disease pathogens. In many cases root pathogens such as Pythium are opportunist and will attack roots that are already weakened. Research studies have shown a direct link between the availability of oxygen in the root zone and infection rates with root rot pathogens—low oxygen treatments typically started to show signs of root decay within a few days of inoculation with Pythium, whereas higher oxygen treatments showed no infection.

Oxygen and physiological disorders Oxygenation in the root zone is also linked to a number of physiological disorders, many of which become more pronounced under warmer and more stressful growing conditions. Blossom end rot (BER) of tomatoes and capsicum and tipburn of lettuce, strawberries and many green vegetables all have environmental influences. However, suffocation of the root zone has been shown to induce high levels of these disorders. This is because the main plant nutrient most affected by a lack of oxygen in the root zone is calcium. Calcium, unlike the other major nutrients, is absorbed primarily through unsuberized root tips. The root apex has a large energy requirement for new cell production and growth and is therefore vulnerable to oxygen stress. If an increasing number of root tips begin to suffer from an oxygen deficiency, a shortage of calcium in the shoots becomes more likely and this makes the development of calcium-related disorders such as BER and tipburn more common.

Good levels of oxygen help ensure healthy root systems.

Oxygenate, Respirate or Suffocate

NFT systems rely on a thin film of nutrient flow, which allows plants to access oxygen from both the solution and moist air in the channel.

How to oxygenate to maximize growth In solution culture, plants obtain oxygen dissolved in the nutrient solution and also directly from the moist air in which the upper level of the root zone should be sitting. Completely submerging roots in NFT is not ideal, as this significantly reduces plant root access to the much higher concentration of oxygen in the air compared to that in the nutrient solution. Aeroponic plants obtain sufficient oxygen from the air directly surrounding the misted roots, while plants in media-based systems obtain oxygen dissolved in the nutrient solution and from the air-filled pore space surrounding the roots. The air-filled pores surrounding the roots become flooded with nutrient during irrigation, though, and only after draining do they refill with fresh air. For this reason one of the best ways of keeping the root zone bathed in fresh oxygen is to control irrigation, so that the air-filled pore spaces are permitted to fully drain between applications of nutrient. Overwatering causing waterlogging is the main cause of root suffocation in media-based hydroponic systems. In ebb and flow systems there is a good opportunity to push and drag fresh air down into the root zone with each cycle; however, this will only occur if complete and full draining of the growing media occurs. Poorly designed ebb and flow systems often have a ‘perched water table’, where excess solution sits in the base of the growing containers even after the drain cycle has completed, and for many plants this can cause root suffocation issues over time. In NFT—nutrient film technique—the ideal is to maintain a thin ‘film’ of nutrient, not a deep flow, so that roots can access oxygen directly from the air above the .04 to .08 inch flow of nutrient. In pond or raft systems it is vital that sufficient oxygen is introduced via the nutrient solution, so active aeration via

Maximum Yield USA | June 2011

compressors or air pumps at regular intervals in the pond are important for crops that have a high oxygen requirement. All nutrient reservoirs should have some form of oxygenation to help boost DO levels in the solution. The cascade or fall-back method works well, and the higher the fall-back of nutrient into the reservoir the more oxygen will be introduced into the solution. Fountains, air pumps with air stones to break up the air flow into smaller bubbles and other oxygen enrichment systems are all worth investing in for a healthy crop and maximum root respiration rates.

How to measure oxygen Dissolved oxygen (DO) in solution can be easily measured with use of a handheld electronic oxygen meter, and there are also less expensive test kits designed for use in aquariums available, although these can be somewhat less accurate. Dissolved oxygen meters have the ability to give readings for DO in parts per million and also to record temperature and then express the oxygen levels as a percentage of saturation. This percentage of saturation measurement is actually a more meaningful guide in hydroponics systems, as it is an indication of how well the aeration methods used are working within the system at any given temperature. At the nutrient reservoir dissolved oxygen levels should be at least five to six ppm under warm conditions (solution temperatures 50 to 68°F), and a well-oxygenated solution at 50°F can be as high as 12 to 13 ppm. Super-saturation with oxygen is also possible using various technologies, and this has also been shown to boost plant growth and yields in a number of hydroponic crops.

Oxygen enrichment not only improves crop performance, but also root health and size.

Maximum Yield USA | June 2011

Oxygenate, Respirate or Suffocate

Different crops and oxygen requirements As a general rule, the larger the plant and the leaf area of the crop, the higher the demand for oxygen. Small plants such as lettuce have a relatively low requirement for oxygen in the root zone, while larger, longer-term fruiting plants such as tomato and cucumber place much greater demands on the root zone for oxygenation. In solution culture systems, the number and size of plants dependent on the oxygen supply in the nutrient determines how fast oxygen will deplete. For this reason growers should consider installing the largest nutrient reservoir they can, as this slows the change in rates of oxygenation as the temperature increases during the day. Oxygen has also been known to deplete from one end of NFT channels to the other under

warm growing conditions, so limitations in channel length should be considered when crops such as tomatoes and cucumbers are being grown. Oxygen shouldn’t be forgotten— along with CO2 and all the mineral ions, it is essential for plant functioning and health. While it may not be necessary to directly measure DO levels every day, it is important to take oxygenation into consideration when thinking about the design of a hydroponic system, the frequency of irrigation required and the type of growing media and aeration methods to be used in the reservoir and in solution culture.

BONSAI by Broo rri s kelynn Mo

Miniaturize your favorite tree with this ancient art. Bonsai plants are, in their essence, little trees.Yet the art of bonsai has a much greater scope: it strives to replicate nature. It is an art that emulates the elements and their action on living plants. A tree is just a sapling until the roots grow, the water

comes into the soils and the forces of sun (light), wind (ventilation) and gravity sculpt it into shape. The bonsai artist uses a variety of tools to replicate these effects and create a perfect miniature version of life on Earth.

Watching your tiny tree as it cycles through the seasons, going dormant, pushing out leaf buds, blossoming and then producing fruits or berries is very rewarding, and a wonderful way to connect with the natural world. Reprinted with permission from Craftzine.com

Because bonsai can re-create complete landscapes, the impression of grand natural space exudes from these small displays. Aesthetics dominate the art of bonsai.

Start

Choose your tree. Choosing the species of tree to grow is the first, and possibly most difficult, task. Pines and maples are perhaps the most recognizable bonsai. These trees are classic beauties and well suited for miniaturization. Flowering and fruiting trees are popular as well, especially the quince and pomegranate. But bonsai trees are not necessarily always trees. Many shrubs can be grown and manipulated into bonsai forms that belie their natural state. Wisteria vines and azaleas can be shaped into thick tree trunks that they would never produce normally. The tree can be grown from seed or propagated through a cutting. The easiest way to begin is to select a sapling from your favorite nursery.

Select a complementary container. The chosen tree will dictate its container. The two must make a visually pleasing combination. Traditionally, the intended shape of the tree is matched to a specific pot. For instance, a straight-sided pot would be used for a straight-growing formal upright style tree while a round or oval pot would be used for an informal style with a curving trunk or limbs. The same rules state that evergreens should be exclusively set into unglazed containers.

While there is room for variance, in general you’ll find that your eye will naturally follow some of these same rules of design, out of instinct. When choosing a pot, consider the sides and consider the depth. If you’re growing a tree that will cascade out of the pot like it’s growing on the edge of a cliff, you’ll want to choose a tall pot; a collective planting meant to look like a meadow needs a wide and shallow one. Finally, select the hue of the pottery. Try to complement the color of the leaves most of all.

Prepare the soil. Dirt is a tree’s lifeline. The soil clinging to the roots provides the tree with its moisture and nutrients. It is crucial to use a mix that will hold water, but not keep the roots too wet. The grain of the soil is also a consideration. When a tree’s root encounters large, sharp rocks, the tip of the roots splits in two and grows around it. The result is a finer, thinner root, unable to take up as much water as a large root, therefore contributing to a natural miniaturization. Plant your bonsai tree in soil with a combination of rich dirt and larger bits of rock to replicate this effect.You can purchase specialty soil, custom-tailored to suit the unique texture and drainage needs of bonsai, or you can customize your own soil with raw materials such as bark, coconut fiber, perlite and rock chips.

Plant the bonsai. 4a) If the pot does not have d drainage holes, use a drill with a ceramic bit to add a hole. To prevent soil loss, cover it with a piece of screen (figure D). 4b) Before planting, gently remove the tree from its container and inspect the roots. They will likely have grown around each othe er. Pull loose these tangled, skinny roots with your hands, and trim away the shaggy ends with hand shears (figure E). Also remove any brown or unhealthy roots. Next, find the taproot (the primary root), and cut if off. This is an important step to dwarf the plant. Finally, fan out and thin the roots at the base of f the trunk using the rake. Always use a gentle touch with the roots. 4c) Cover the bottom of the pot with soil. Add the tree with its roots fanned out wide. Cover the roots with soil, filling the pot evenly until the surface of the dirt is level. Now give the tree a generous drink, to “water it in” (figure G). Finally, add any moss, rocks or companion plants to flesh out your design (figure H).

Shape the bonsai. When shaping trees, the objective is to manipulate the tree without scarring the bark, to create the illusion of years of natural stress from the forces of nature. Start slow, with gentle tension.You can gradually increase the tension over time. Here are three methods: »Wire. When wiring, use care not to damage the tree. Don’t wrap the wire too tightly around the wood. Check the wiring often, removing and replacing it as the tree grows. Begin by coiling one end of the copper wire around the base of the tree, and wind it along the trunk or branch you wish to bend (figure J). Be certain to lay the wire evenly so as to properly distribute the pressure. When the tree has been wired, bend the branch or trunk carefully with both hands, gripping evenly to avoid snapping the tree. »Tie. Tie a piece of thin hemp rope or cotton twine around the J pot. Now tie a piece of twine to the branch you wish to bend, and pull it down with the string until it curves as you like. To maintain the tension, tie the loose end to the string that’s tied around the pot (figure K). »Weight. Choose a small stone, k not heavy enough to break the tree, and hang it from the trunk or branch with a small length of wire or string. Don’t hang the weight from the very tip, as you could break the tree. Instead, start 1/3 of the way from the tip, wrap the wire or string evenly around until you reach the end and then let the L stone dangle (figure L).

Finish

Displaying Bonsai Potting a perfect tree into a perfect pot is not the final step. This art must be displayed, and thus honored. Placing the tree on a small stand gives it a sense of importance, and elevates it above the common. Consider something simple, such as a piece of cork, a modest wooden plant stand with short legs that doesn’t throw off the balance, a slab of raw slate or a lacquered tray. MY

HOW TO SAVE PEPPER SEEDS

BEGINNER’S CORNER

Maximum Yield USA | June 2011

Here are two easy ways to save pepper seeds and grow your own at home.

Do you want to grow your own peppers? Well, you can start the process by gathering the seeds of your favorite pepper variant. By saving the pepper seeds, you can readily plant them during the appropriate season.You don’t have to rush to your local nursery and look for those pepper seeds and you save money. Saving pepper seeds is simple. In fact, there are two basic ways to collect them effortlessly. You can harvest them from a dried pepper or from a fresh pepper. Note that it is always easier to take out the seeds from red peppers. This way you can be sure the seeds are mature since red peppers are already ripe. Here are the steps involved: Saving seeds from dried peppers

• Start by gathering fresh red peppers and choose the ripest among them. Estimate the ideal number of red peppers that you wish to dry and set them aside. Get a paper plate. Transfer the red peppers to a paper plate, placing them in a single layer and leave them uncovered. • Look for a warm, dry place. Put the paper plate there so the red peppers can air dry; this may take several weeks. Wait until all of them have completely desiccated and make sure to check the insides are dry too.

• When the peppers are leather and dry, you are ready to save them. Cut open each and carefully collect the seeds, placing them in a container, can, bottle or paper packet. Saving seeds from fresh peppers

• Select fresh pieces of pepper making sure they are already ripe. Get one piece and cut it open using a kitchen knife. Once the piece has been cut open, notice the seeds. They still cling to the white membrane inside the pepper. Scrape out the seeds from the white membrane using the end of a kitchen knife. • Transfer the seeds to a plate—leaving it uncovered—and position it in a safe and out-of-the-way location. Allow the seeds to dry for a couple of days, tossing them occasionally. Make sure their bottom layers are completely exposed to air. Wait until everything dries up evenly. When they are dry, save them for future use.

• Precautions: Once you have touched the white membrane of the pepper or the seeds, make sure to wash your hands. Do it several times. It is better if you can use a strong detergent. Peppers have capsicum oil—which can stick to your fingers—and can readily burn your body’s soft tissues. You can hurt yourself, especially when you have accidentally rubbed it on your eye. Aside from planting the pepper seeds that you have saved, you can also reserve them for cooking or you can repack them and give them as gifts. MY (Source: www.howtodothings.com)

Worldwide Opportunities on Organic Farms (WWOOF)

WWOOF It

Goals: See the world on a dime, gain volunteer experience, exercise more and gain an education. How to achieve said goals: WWOOF

Cities can certainly make you feel trapped and disconnected from nature.You can even feel disconnected from your food as so much of what we eat is pre-packaged and heavily processed. Many folks are turning back to planting their own vegetable gardens, a tradition we lost in this country in the 1970s. This return to growing at home isn’t just about producing food, it’s about independence; a quiet, peaceful rebellion against corporate agriculture. However, modern challenges are cropping up in our modern gardens as well, thanks to big ag businesses. Mutant seeds are more popular than heritage and heirloom seeds. A good ole’ smattering of cow dung and other natural fertilizers have been bypassed by complex chemical and fossil fuel based fertilizers in glossy packaging. 78

Even if you don’t have the space (indoors or outdoors) to grow your own food, have you ever yearned to dig in the soil and learn about food-raising practices of yore, the practices of which were based on organic farming? WWOOF No, it’s not a dog with a stutter. WWOOF stands for Worldwide Opportunities on Organic Farms or Willing Workers on Organic Farms. It’s an organization, actually a network of organizations throughout the world, that connect folks with organic food raising in a very hands-on sort of way. WWOOF has been around since the early ‘70s. It’s a simple concept whereby organic farmers offer food, accommodation and training through experience in organic lifestyles in exchange for volunteer help. It’s a great way to see the world on the cheap and opportunities are available in literally dozens of countries around the globe. How WWOOF works The overseeing WWOOF organization for a particular country offers a list of organic farms who accept volunteer help in a variety of areas—planting, harvesting, animal husbandry or maintenance, or a combination of these areas. The volunteer, aptly named WWOOFers, purchase a membership in the country they are interested in and then gain access to those lists that detail all available opportunities.

Maximum Yield USA | June 2011

They choose a host farm and make direct contact with the host to hash out the details. In terms of fair exchange, four to six hours of labor is suggested, depending on the type of tasks involved. How much does it cost to be a WOOFer? The ease of gaining access to these lists is dependent on the country you’re interested in. In the USA, a single membership is approximately US$20 or $30 for a double. That fee will get you a guide listing over 600 organic farm opportunities. Can the kids join in? It appears they can in some cases, and it would make a great experience for your kids. WWOOFer members must be 18-years-old or over, but some farms will let members bring their children; a few even allow pets. How fit do you have to be? While you don’t need to be a triathlete, it is expected you’ll be in reasonable shape. After all, you’ll likely be doing a lot of bending at the very least. Being a WWOOFer is a great way to get in some productive exercise. How long are WWOOF stays? They can vary greatly from a couple of nights to a couple of weeks; some even as long as a year. The length of your stay is negotiable with the host farm. WWOOF-USA Basics The WWOOF-USA host farm directory lists more than 1,000 organic farms (not necessarily USDA certified organic) and gardens across the country. The host farm profile contains information about the location, general responsibilities and lifestyle of the host. Any farm, community or garden project in the USA that is willing to host and accommodate volunteers can participate in our program. We encourage all types of volunteers and hosts who can cooperate to strengthen sustainable agriculture worldwide to be a part of WWOOF-USA. The program is open to anyone 18 years of age or older, regardless of experience. 82

WWOOF farms offer a variety of educational opportunities, including growing vegetables, keeping bees, building straw bale houses, working with animals, making wine and much more. With over a thousand farms in all 50 states, the US Virgin Islands and Puerto Rico, there is something for everyone. You can preview the directory of farms before becoming a member on the website. How it works A WWOOF member contacts the host farms to discuss hopes and expectations to agree on an arrangement. WWOOFing is a way to learn practical farming skills, be part of the organic agriculture movement and experience the heart of American agrarian culture. Once you become a WWOOFer by joining the organization, you will receive online access to the directory of host farms.You can choose to also receive a printed and bound directory of host farms mailed to you. Next, contact the farms you are interested in visiting to check availability and arrange a stay. WWOOFers generally volunteer for half a day in exchange for meals, accommodation and education. The length of a farm stay is determined by you and the host, and can vary from a few days to a season. The key to a mutually beneficial experience is lots of clear and open discussion about expectations before arriving at the farm.

AVANT-GARDENING

Grow

Up! by Charlene Rennick

The solution to your horizontal gardening challenges is as simple as going up instead of out.

ne of the most widely acclaimed advantages of having a hydroponic garden is that it produces a greater volume of crops at harvest time. Hydroponically-based cultivation systems can operate all year long, give gardeners an opportunity to start plants way ahead of the outdoor growing season and pack more plants into less space.

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

Another land-saving, space-creating, energyconserving, hydroponic breakthrough is the vertical garden. Growing upwards instead of outwards gets the most use out of your lights and may help you save coin on your hydro bill.Vertical cultivation techniques may double a crop yield that normally requires 2,600 watt lights.Vertical hydroponic gardening techniques are incredibly energy efficient. Vertical growing also opens up the variety of crops that can be grown hydroponically. Cucumbers, squash and melons—which traditionally require vast horizontal space to produce fruit—have been successfully coaxed to fruition using a cage, climber or homemade support. One of the tricks is to make sure the blossoms have the protective umbrella made up of the big leaves that will shade the growing fruit.This can be done by supporting the maturing fruit from the bottom and the main vine and offshoots from the top.

Cucumber, pumpkins, squash and melons are members of the vine family, which gives them the predisposition to become climbers if it weren’t for the weight of the fruit. With braces and cages to counter the weight, these large and tasty treats can be a welcome addition to your indoor harvest without taking up space. The roots will need this kind of anchor to balance the weight of the yield against gravity. Clay, pebbles and other heavier, porous growing mediums also provide a good base. All of these options for a growing media suitable for vertical systems still require a reservoir, pumps to move the water around and irrigation fittings. Good luck growing up! MY

Compost Bins and Garden Waste Disposal

[

by Casey Jones Fraser

Stop trashing and start composting—it’s great for your gardens and the planet.

Maximum Yield USA | June 2011

Gardening is a hobby that produces waste. There is no way to get around it. Every gardener—whether they deal with hydroponics or soil—knows the hassle of throwing away all of those root balls. In a post-harvest situation, root balls and growing media are usually wet and heavy. Filling plastic garbage bags and sending them off to the landfill is cumbersome to the grower and harmful to the environment. In my experience, most of the waste matter from an indoor garden is organic: soil, leaves, roots and so on. So why not make valuable compost from this stuff instead of throwing it into a landfill? Considering the work involved

with trashing your scraps, gathering and turning compost should be easy. Wait, don’t stop reading! I know some of you are thinking “Composting?! I’ve heard this before...” Well, this compost plan is specifically for indoor gardeners. I’ve got an easy-to-build and easy-to-use compost system that will be the perfect addition to your garden process, and you will be thrilled with the effective waste removal. I got this idea when a customer asked me for a compost starter product. I offered her a large root ball that I was about to throw away. “This soil was fed a highend organic nutrient system, with lots of beneficial fungi and bacteria. Those are

[

“Old roots are loaded with dormant fungi and bacteria that will help future roots develop and thrive.”

the exact things you need to get your compost going,” I told her. I also sold her a high-nitrogen organic granular fertilizer to go with it. The results were successful, and her compost began breaking down at a much faster rate. It occurred to me that we gardeners are always throwing away these old root balls, while plenty of people are trying to find products that offer nitrogen and beneficial biology for their compost. If you pile up all of these starchy, biologycovered roots combined with a nitrogen source, it will start to break down in a matter of days—it has all of the right ingredients. The resulting compost makes a great top dressing for outdoor gardens, as well as a potting mix for container plants. All you need to purchase for this compost system is a few fence posts, some chicken fencing and a small box of metal staples. Specifically, get six five-foot fence posts and two three-foot fence posts. I use plastic poultry fencing for the inside edges, but almost any type of screen will work just as well. For the staples, I’m talking about the heavy-duty ones that you hammer into place, not the staple gun variety. Next, score some free shipping pallets from your local hydroponics retailer. The best pallets are made of rough-cut oak. This wood is not painted or treated in any way, so there is no chemical runoff into your compost. Also, the oak wood is tough; after about three years you will probably need to replace the pallets as the wood will begin to decompose, but starting with oak will ensure relative longevity.

“Wait, don’t stop reading! I know some of you are thinking “Composting?! I’ve heard this before...”

When building a compost bin or using wood for a raised bed garden, always avoid glued or treated wood. Find a suitable spot in your backyard for the compost bin. You will need at least four square feet for the bin. For larger gardens, or more eager organic gardeners, find enough space for three four-foot squares. Place the shipping pallets on the ground as shown, leaving the four foot square open. Once the pallets are in place, you can begin adding fence posts. Each pallet requires two fence posts at its base. That’s six posts in all—the two short ones will be used later. Maximum Yield USA | June 2011

Waste Not

Start with six five-foot fence posts, two three-foot fence posts, some poultry fence and a few oak pallets.

For the next step, you will probably need a partner, because oak pallets are heavy. Slowly lift each pallet over and onto each pair of fence posts. The fence posts are the wall supports, and the pallets are the walls. With proper spacing, there will be almost no gaps in the corners, as the two side walls fit snugly up against the back wall. From here you will need to add chicken fencing or some sort of heavy-duty screen to the walls of your new compost bin. This extra step keeps the garden scraps inside the compost bin instead of falling through the slots. To secure the fencing, you will need a hammer and a few heavyduty staples. Line the bottom three feet of the bin with fencing or screen, then hammer the staples into place,

fixing the fencing to the pallets. At this point, the bin is almost complete. The final step in construction is adding the fourth pallet, which will act as a door or gate for the compost bin. This step is extremely important if you have pets.A few years ago, my Great Dane got into the compost and started eating it! I didn’t actually see him eat the rotting waste; what I saw was the bloody aftermath in the yard.We had to rush him to the emergency vet—he was so

sick that he almost died of dehydration.These days I make sure the fourth pallet is secured, so my pets eat pet food instead of compost. Now, to put the gate in place, grab those short fence posts and hammer them into the ground at the mouth of the bin where the final pallet will be placed.

Wooden pallets (used for shipping) are available for free. Just ask your local hydroponics store.

Lay three pallets on the ground where the bin will go. Start hammering in fence posts at the edge of the pallets (two posts per pallet).

Take a deep breath. Lift a pallet over your head, and drop it down onto the fence posts.

With the short fence posts in the ground, it’s time to complete the bin. Take your fourth pallet, lift it and drop it down onto the short fence posts. If this pallet does not fit snugly against the front of the bin, pull up the fence posts and reposition them for a tight fit. With the final pallet in place, the compost bin is complete. If you are like me, you have dozens of root balls that need disposal. Plenty of growers out there have piles of root balls weighing hundreds of pounds. Almost any type of growing medium can be composted in this way, but you should avoid plastics and poly-based materials in your bin. Organics break down quickly, while synthetic materials can take years to start degrading. With the gate removed, I dump root balls, soil, leaves and so on onto the pile. This will need to be turned and stirred about three times per week or more often if you have the time. Your motivation for all this work? When you pack all of your garden waste into a trash can, it will still look the same weeks later—why not just make it all disappear? And nature does most of the work! Maximum Yield USA | June 2011

Waste Not

Line the inside of the bin with poultry fencing or some other type of screen. This will help keep the compost inside the bin.

After adding all of your garden waste to the compost pile, start mixing and chopping with a shovel, as thoroughly churning the compost speeds up biodegradation. Chop everything with a shovel until the stems and leaves are unrecognizable. Replace the gate by dropping it onto the short fence posts. Remember to turn the compost with a shovel every few days. If it gets too dry, add water to encourage faster decomposition of plant matter. Don’t be afraid to throw on some kitchen scraps (avoid meat and dairy) and

yard waste (avoid pet feces). Moldy bread, rotten produce, egg shells, coffee grounds, tree leaves and grass clippings are all valuable additions to your compost, and will encourage bacterial and fungal colonies to breed and further break down your garden waste. Kitchen scraps and yard waste will also add organic nutrients to the compost mix, which will increase the compost quality.

Multiple bins

Now consider three compost bins instead of just one. With a few more fence posts and shipping pallets, you can easily turn your single bin into a three-section compost system that will allow you to harvest rich compost every six weeks. 98

Maximum Yield USA | June 2011

Add the two three-foot fence posts for the front pallet. This front pallet will act as a gate to enclose the compost. Lower the pallet onto the short fence posts, just to make sure it fits tightly into place.

DERIVING NUTRIENTS FROM MARINE LIFE

Life is abundant under the sea, and some of these life forms can be excellent sources of complete nutrition above the sea for your plants.

Plants have to receive certain nutrients in order to survive and thrive. They need nitrogen, phosphorous, potassium and an assortment of trace elements, amino acids and vitamins. When growing indoors, the gardener must provide the plant with these essentials—but with so many different products on the market these days, it is difficult to decide which nutrient sources are most complete and best for your plants. The sea can be a beacon of light for unsure gardeners. There are many different sources of plant nutrients that come from the sea—nutrients such as kelp meal or extract and fish emul-

102

Kelp is a type of seaweed that grows quickly and abundantly in the ocean. Kelp and other seaweeds are excellent organic sources of many of the nutrients that plants require for optimum growth, and they are available for gardeners as kelp or seaweed meal in a ground powder or as kelp or seaweed extract in a liquid treatment. Kelp meal is applied as a top dressing to plants or mixed into the soil before planting, while kelp and seaweed extract can be mixed into hydroponic irrigation solutions, watered to potted plants or foliar sprayed—each way is an effective means of delivering quality nutrients to your plants. Kelp contains nitrogen, phosphorous and potassium, and is also a natural source of 60 to 70 trace elements that are in a water soluble state, which means they are instantly available to the plant. Kelp and seaweed are abundantly rich in many vitamins such as A, C, E and B-12 as well, and they also contain many amino acids and plant hormones. Kelp meal or extract has other advantages as a plant nutrient. Kelp will break down quickly—making nutrients available to the plant right away—and it contains vitamin B-12, which reduces plant stress, helping with shock from transplanting, environmental damages, insect damage or disease. Kelp or seaweed can also increase the bioactivity in the soil at root level, helping to break down organic matter and making it available to the plant as food. Kelp and seaweed in the soil can help with water retention as well. There is one downside to using kelp as a plant nutrient, however—because it would seem that earthworms do not like to eat fresh kelp.

Earthworms break down organic matter and aerate the soil, and while kelp will not harm them in any way, the earthworms just do not seem to want to eat it. Our next set of marine-based nutrients comes directly from fish. Fish meal and fish emulsion are both excellent organic products that can be very nutritious for plants. Fish meal is dried and ground whole fish or fish trimmings with most of the fish oil removed during the drying process in order to prevent the fish meal from going rancid. There are many reasons fish meal is a great plant nutrient. Fish meal is an excellent source of six to eight per cent nitrogen, five to seven per cent phosphorous and many trace elements, although it is not a good source of potassium. Just like kelp meal, though, fish meal is a great bio-activator, improving the breakdown of compost and organic matter. The downside to using fish meal as an organic plant fertilizer is really just the odor—it smells like fish. To control the odor, cover the top dressing of fish meal with some soil. You should also make sure to keep the fish meal in an airtight container to prevent pets and insects from getting into it. Fish emulsion is the liquid version of fish meal, and is made by using enzymes that digest and ferment fish remains. Fish emulsion is also a great source of nitrogen, phosphorous and many trace elements. There are certain benefits to using fish emulsion over fish meal. Being already broken down and in liquid form, the nutrients in fish emulsion are immediately available to the plant, whereas the fish meal needs to be broken down. Fish emulsion is hard to overfeed, making it safer to use than fish meal, and it is also an excellent bioactivator that can assist in the breaking down of compost and organic matter. Fish emulsion can be added into hydroponic nutrient reservoirs and hand-watered to potted plants as well, making it more versatile than fish meal. The drawback of using fish emulsion is again the odor. Even though you can find ‘deodorized’ fish emulsion, 104

Ventilation The Whole Truth

Grow spaces of all shapes and sizes—large or small, hobby or commercial— need airflow. Detailed are the benefits of ventilation and how to integrate fans into your space. Our planet is dynamic with low pressure and high pressure systems colliding and creating wind. The wind can dry or moisten an environment, which in turn can open or close the stomata on the surface of leaves. If the humidity is too low the plant’s growth will slow down; if the humidity is too high bacteria and fungi can flourish.

110

Maximum Yield USA | June 2011

ventalation benefits

In an indoor growing environment, fans are a necessity. They emulate our planet’s dynamic pressure systems keeping the temperature and humidity at a constant level. Besides lighting they are one the most important component in an indoor grow set-up. Carbon dioxide is an integral component of plant growth. Even if nitrogen, hydrogen and carbon are present and plentiful at the root level, insufficient airflow will result in a missing element in the plant’s construction material.

A fan will keep the plant breathing, metabolizing and growing at an optimum rate. The diverse selection of fans on the market includes do-it-yourself hydroponic computer fans, centrifugal (squirrel cage) fans, vortex fans and more that will all do different jobs in different situations. In situations with high intensity discharge (HID) light (more than 400 watts burning), a small fan under 250 or 300 CFM (cubic feet per minute) will not do the job. A general rule of thumb is if you have 400 watts of light you should have at least 400 CFM per bulb and if you have 600 to 1,000 watts you should have 600 CFM per bulb. Another way to calculate volume of air exchange in a room is mathematically. Knowing the length, width and height of the room, you simply multiply these three numbers to find the proper fan that will exchange your air in one minute. For example, a 10 by 10 by eight foot room is 800 cubic feet so your fan must be at least 800 CFM in order to achieve the one minute exchange.Very small areas can use smaller fans, but a small area can get heat buildup very quickly and will still need good steady air flow. In cases where heat buildup “In cases where heat buildup is a problem (even in is a problem (even in large rooms) an intake fan pushing the same volume large rooms) an intake of air as the outtake fan can be installed down low fan pushing the same volume of air as the in the opposing wall to help cool the air faster and outtake fan can be make the air tumble through the garden.” installed down low in the opposing wall to help cool the air faster and make the air tumble through the garden. An oscillating fan blowing gently across the leaves in tandem with intake and outtake fans will keep the plants fed well with carbon dioxide and will make the plants’ stems stronger at the cellular level. If heat or cold is a problem all fans can be hooked up to dimmer switches or heating and cooling thermostats to keep the room between the proper temperature parameters. All fans run on a curve and there is a point at which the fan runs most efficient. Every piece of equipment placed in front of or behind the fan has a negative effect on the performance of the fan. • Louver or butterfly dampers will impede the progression of air to a degree. • The ducting will affect airflow. Straight, smooth, galvanized ducting will let air flow better than plastic ducting with ribs. The ribs create small baffles along the length of the ducting and static pressure will build up in the duct work. • Length of pipe is another important consideration. The shorter, straighter span of pipe or ducting should be used for the most efficient air flow. According to heating and cooling duct work contractors, every 45 degree bend adds 10 feet to the length of duct and a 90 degree bend is something that will start to work against the fan; the air will actually find its way back to the fan and leak out into the room.

112

“When you are shopping for a fan you are going to get what you pay for. Purchasing a fan too small or of inferior quality spells trouble. Don’t be afraid to spend the money on a good fan.” • A fan should always be set up level. Hang the fan straight up and down vertically or perfectly horizontal. If you hang the fan off kilter the bearings will rub together unevenly and over time the fan will start to make unbearable sounds and in the worst case, will stop completely. • By sealing all connections and air leaks with silicone or metalized ducting tape you will ensure complete airflow with no air escaping back into your room. All these components in front or behind the fan should be taken into consideration when you are envisioning your room. Airflow and movement are very important in the garden. When you are shopping for a fan you are going to get what you pay for. Purchasing a fan too small or of inferior quality spells trouble. Don’t be afraid to spend the money on a good fan.You wouldn’t buy a $700 fishing rod and put a $3 reel on it, would you? Having a good quality and properly sized fan should be one the strongest links in the chain. Helpful Hints: • Decide where you are going to place the fan in your room. High up in a corner is best for expelling hot air. • Get the proper fan size to change the air in your room a couple times a minute. • An 800 cubic feet room requires a minimum 800 CFM fan. • Make sure the fan is level horizontally or vertically. • Make sure the length of your ducting is straight and as short as possible. • Purchase a fan that is more powerful than you need in case you add carbon filters or air cooled shades. • The intake fan should match the outtake fan. • Seal all connections with silicone or metalized duct tape. • Use an oscillating fan for mixing air and creating a gentle breeze across the plants leaves. • And finally, spend money on a good quality brand name fan, and it will be the only fan you will ever need.

Indoor Herbs for Summer Drinks by Matt LeBannister

All in favor of a refreshing twist on summer drinks, raise your glass.

116

Maximum Yield USA | June 2011

After an abnormally long winter—that in many parts of the country lasted through spring—summer is finally here. With summer comes warm weather and long, sunny days. These days are filled with fun in the sun by the pool, at the beach and in the garden. To cool off why not enjoy a delicious summer drink accented with some of your indoor garden herbs. The herbs suggested in this article can be grown easily under fluorescent lights or in a sunny windowsill. There are many herbs that grow easily indoors that add a unique, refreshing twist to summer drink standards.The one that is most often used and is the most versatile is mint, of which there are many varieties. The most common varieties for summer drinks are peppermint, spearmint, lemon mint and orange mint. Each has its own unique flavoring so preference is up to the individual. Each type of mint makes a great addition to mint juleps, mojitos, lemonade, iced tea, fruit punch and iced soda water. A pinch or sprig of mint leaves in a cool summer drink can make any drink special and extra refreshing. Another herb that makes a great addition to certain summer drinks

is basil.There are many different varieties of basil including sweet basil,Thai basil and lemon basil. Each has a unique taste and smell. Fresh basil will best accent iced tomato or vegetable juice, Caesars and Bloody Marys. Basil has a very strong flavor and can over power the drink if too much is added. A great way to ensure the basil does not over power the other flavors is to freeze one to two leaves of basil in an ice cube the night before. As the ice cubes slowly melts the flavor will release into the drink.This can be done with any of your favorite herbs. Another great way to infuse a drink with herbs is to make your own herb flavored syrup.To

do this first choose your favorite indoor grown herbs. Mint, lemon balm, basil, thyme, tarragon, basil and lemon verbena all grow easily indoors and taste great. To make the syrup first add a half cup of sugar and a cup of water into a small sauce pan. Bring the mixture slowly to a simmer, stirring until the sugar dissolves and the mix thickens.Take the pan off the heat source and add a few pinches of your favorite herb. Once the syrup has cooled, 30 minutes to an hour later, strain out the herbs and allow the syrup to continue cooling in the fridge. Now the syrup is ready to be added to your drink.You can make a great summer herb drink by adding two to four tablespoons of your newly made syrup to a glass of soda water and ice. Garnish with a slice of lemon or lime, serve and enjoy. There are so many great herbs and great summer drinks that you can mix and match. Experimenting until you find the perfect combination is part of the fun.With the variety of herbs that can be grown indoors, it’s unlikely you’ll ever run out of fresh summer drink ideas. MY

Water-cooled devices like ice boxes for HID lights and fans also revolutionized the way grow rooms operated, particularly in hotter regions, but tended to scare some growers off because they were at first not that well understood. However, trial and error is now revealing more user-friendly ways to make water-cooled rooms a viable answer to year-round growing by using the properties of water to expel larger volumes of heat than would be possible with air conditioners. Although these kinds of cooling strategies are not always applicable, you should consider them before investing in a final decision. In hydroponics, one advance in particular is making a major difference in the way deep water culture systems are operated.

What is Permaculture? by Emma Cooper

PERMACULTURE is a combination of two words—PERManent and agriCULTURE or simply CULTURE—used to describe a way of designing systems for human use that meet our needs sustainably. The term was first used in the 1970s by two Australians, Bill Mollinson and David Holmgren. Permaculture is a method of design that encourages efficient and productive systems for producing food to provide for our material needs or to simply create healthy communities, based on three core values. Earthcare encourages us to think about the effect our activities have on the planet and to develop ways to live more sustainably. Peoplecare aims to develop healthy communities, by respecting and supporting everyone. Fairshares place realistic limits on individual consumption so that the planet’s resources are used wisely and equitably. Permaculture includes many design concepts inspired by natural, sustainable systems. It’s important to look at the system as a whole, not the individual parts, so that the connections between the parts

are visible and each part can be put in the right place. In terms of a community, this might mean ensuring that homes and workplaces are close together to avoid the need to commute. In gardening terms it would mean placing the plants that need the most attention closest to the house, while placing perennial plants further away from the house. Designs make the best possible use of resources to minimize inputs (including human effort) and maximize outputs. Waste products are used as inputs elsewhere— either reused or recycled locally. Although permaculture design can be applied to anything we create, currently its most well known applications are for gardening or agriculture. A forest garden is a system for growing food that mimics a natural forest. Several ‘layers’ of plants grow at different heights, making the best possible use of the space, light and available nutrients.The seven layers are the root zone, the soil layer, herbaceous plants, shrubs, low trees, the canopy (tall trees) and climbing plants.The majority of the plants used in forest gardens are perennial or self-seeding. In a well-planned forest garden there is little maintenance required after the initial planting, but there is always something useful to be harvested. Although most of the plants will produce food, many forest garden plants have multiple uses— providing herbal medicines, dye and fibers. In fact, the list of possible uses for plants is almost endless.

“Although permaculture design can be applied to anything we create, curretnly its most well known applications are for gardening or agriculture.” Another example of permaculture design is the herb spiral where herbs spiral around a mound of soil. The south-facing side of the mound is sunny and hot; the north side is cooler. The top of the mound is drier than the bottom. The idea here is that each herb is given its ideal growing conditions, and will be healthy and productive. Permaculture is a very large and interesting subject, and hopefully this brief introduction will encourage you to learn more. MY ABOUT THE AUTHOR:

CFL Disposal and

Advice on safely disposing of or recycling compact fluorescent lamps after their useful life.

I’ve been a big fan of compact fluorescent lamps (CFLs) for years, first using them in the 90s when they were still around $20 a pop and were more cumbersome. Nowadays you can get them for just a couple of dollars. The cost has plummeted and they come in all sorts of wattages, shapes and sizes to fit the vast majority of standard light fittings. Incandescent bulbs not only consume excessive energy but also make a hole in your wallet in comparison. Some countries have also officially sounded the death-knell for incandescent bulbs, with plans to phase them out over the next few years. But a new predicament faces us—what to do with the bulb once it’s completed its useful life. I’ve had several e-mails on this topic just over the last couple days. It’s been great to see environmentally conscious people thinking past the purchase. Thankfully, CFLs last for a very long time—two to five years. Given their growing popularity though, that does mean in a few years from now we’ll be faced with many CFLs needing to be responsibly disposed of or recycled. 128

Recycling

Don’t bin your CFLs Throwing CFLs in the bin isn’t a good idea. Aside from the waste of materials, they contain a small amount of mercury; approximately three to five milligrams. It’s a tiny amount, about the size of the very tip of a ballpoint pen and far less than what is present in a watch battery. Still, 100 million of these small amounts does become significant. There has been quite a bit of panic about mercury in CFLs. I’d hazard a guess that CFL mercury levels would be far less than the additional mercury emissions involved in powering a comparable incandescent globe over the same period of a CFL’s lifespan. Additionally, at the end of a CFL bulb’s life, little of the mercury remains in its most toxic form. Regardless, given the fragility of the bulbs, caution is necessary and mercury shouldn’t wind up in landfill at any time and at any level. Mercury is a powerful toxin that contaminates earth, air and water and accumulates in animal tissue.

How to dispose of CFLs The best way to find out how you can recycle or safely dispose of CFLs is to contact your local waste authority for advice. Contact your electricity authority; some utilities are providing their customers with CFL recycling or advisory services. Another option is to ask the retailer who supplies your bulbs if they have a recycling program. Some larger retailers have programs in place already. It’s a good opportunity to put pressure on retailers who don’t by letting them know you’ll buy your bulbs from outlets that do provide this program. If all of the above proves fruitless hang

onto the bulbs by placing them in a crush-proof container. The issue of mercury in bulbs will become more pressing and as the green revolution really starts kicking into gear, governments and manufacturers will be forced to provide proper facilities. You should not place lamps in your regular recycling collection because they can shatter while being transported or sorted and contaminate recyclable items, putting recycling center staff at risk.

What if you break a CFL? • Open windows in the room to air out for 15 minutes before cleaning up. • Don’t use a vacuum as this will spread mercury into the air. • Wear gloves when cleaning up. • Use a disposable brush to gently sweep up fragments. • Use a moist paper towel to help pick up remaining tiny fragments. • Wrap the pieces up in layers of newspaper and place in a sturdy sealable bag or container along with anything used to clean up the mess. Place the container or bag in your rubbish bin. It should be treated as hazardous chemical waste; i.e. stored safely until it can be taken to a hazardous chemical disposal facility. Given all that messing around, it just pays to be extra careful when handling a CFL bulb. If the idea of using anything containing mercury really bothers you, perhaps consider LED lighting as a mercury-free alternative. LEDs are even more energy efficient and have a longer lifespan than compact fluorescent lamps!

Foliar Nutrition for Plants by Bentley Mills

It is common knowledge that plants are able to absorb essential elements through their leaves. The absorption takes place through the stomata of the leaves and also through the epidermis, and while the movement of elements is usually faster through the stomata, the total absorption may be just as great through the epidermis.

Plants are also able to absorb nutrients through their bark. The following elements have been successfully used to supply nutrients for plant growth by applying them as foliar leaf sprays:

Primary Nutrients

Secondary Nutrients

Micronutrients

Nitrogen Phosphorus Potassium

Magnesium Calcium Sulfur

Iron Zinc Boron Copper

Molybdenum Manganese Chlorine

One difficulty in using foliar sprays to supply essential elements to crops is that translocation of the applied element may not be rapid enough for increasing crop yields.With some plants this problem is more difficult than with others. For example, the relative mobility of essential nutrients in bean plants when applied as a foliar spray—in order of decreasing mobility—was as follows:

Mobile

Partially Mobile

Immobile

Potassium Phosphorus Chlorine Nitrogen

Zinc Copper Manganese

Boron Calcium Sulfur Iron

Molybdenum Magnesium

Nitrogen fertilizer compounds have been used for several years as foliar sprays. Sodium nitrate, ammonium sulfate, potassium nitrate and urea have all been used experimentally, but only urea gives satisfactory results, as the other fertilizers cause leaf burning due partly to the high osmotic concentration of the spray solution.

132

Maximum Yield USA | June 2011

Urea has been successfully sprayed on apple trees, tomatoes, celery, lima beans, potatoes, cantaloupes, cucumbers and sugar cane. Amounts ranging up to 15 pounds of urea per acre at one spraying have been used with beneficial results on apple trees, but higher concentrations will burn the leaves. The usual concentration for apple trees is five pounds of urea per 100 gallons of water, and this is commonly mixed and applied with regular spray materials at weekly intervals early in the growing season. The application of urea fertilizer to leaves of plants has been shown to achieve results approximately equal to those obtained when fertilizer is applied to the soil—the uptake of urea is faster when it is sprayed on the leaves, but it is cheaper to apply it to the soil. Phosphorus is also capable of being utilized by plants when it is sprayed on the leaves. Although the practice is not common, there are many good reasons for predicting that there may be an increase in the foliar application of phosphorus. One reason is that in most soils only a small percentage of phosphorus fertilizers can

be utilized by the plant (averaging about 20 per cent for the first year) whereas with foliar application nearly all is absorbed. In one experiment, in fact, approximately three pounds of P2O5 sprayed on tomato leaves gave a greater early growth than did 135 pounds of P2O5 applied to the soil, and the yield of tomatoes was 12 per cent greater when the entire 135 pounds of P2O5 was sprayed on the leaves.

satisfactory. Magnesium is now commonly applied to plant foliage as a solution of magnesium sulfate (Epsom salts). One reason for the popularity of the practice is that soil applications of magnesium commonly take three years to correct magnesium deficiency symptoms of such perennials as apple trees, whereas foliar sprays are effective within a few days after application. A foliar applica“Sulfur sprayed on leaves is readily absorbed by plants, a fact that was demonstrated in connection with the study of certain sulfur sprays when used as fungicides.” tion of a two per cent solution of MgSO4 to tomatoes, oranges and apples has been shown to relieve magnesium deficiency and has also increased crop yields. Calcium is not usually applied as a foliar spray because it can be just as efficiently applied to the soil. If CaCO3 is too slow in reaction then CaO or Ca(OH)2 can also be used as soil applications, while CaCl2 is the primary method of applying Ca to foliage on the occasions this method is used. Sulfur sprayed on leaves is readily absorbed by plants, a fact that was demonstrated in connection with the study of certain sulfur sprays when used as fungicides. Although there have been no reports of a sulfur deficiency being relieved by sulfur sprays, the practice may become established because it is physiologically sound. Iron has been sprayed on foliage by growers since about 1916 to relieve chlorosis. The first research on this subject was carried out with chlorotic pineapples growing on highly alkaline soils in Hawaii, and periodic sprays of five per cent ferrous sulfate are now common practice on Hawaiian pineapple plantations. The biggest obstacle to this practice is the fact that even though the iron moves readily into the leaves, it is translocated very slowly. As a result, even after spraying with ferrous sulfate, chlorotic spots may still be in evidence

134

Maximum Yield USA | June 2011

in places which did not receive any of the iron spray. Iron sprays have been shown to be highly effective, though—the leaves of chlorotic grain sorghum on calcareous soil in Tulare County, California, were sprayed with 40 gallons per acre of three per cent ferrous sulfate solution about one week before heading, at a cost for materials of 50 cents per acre. The yield of grain sorghum was increased from 540 pounds of grain on the untreated plot to 1,774 pounds on the treated plot—an increase of 222 percent. Iron chelates have also been successfully used as a spray application. On alkaline soils where iron chlorosis is common, applications of iron compounds to the soil have not been very successful, however, because the iron is soon rendered insoluble. Applications on the soil of more than 3,000 pounds per acre of ferrous sulfate were required to accomplish similar increases in yields.

Manganese becomes less available in alkaline soils, and many states in more humid regions of the country often report manganese deficiencies in peat and muck soils and in local areas of alkaline soils. Manganese deficiencies are frequently corrected by spray applications of manganese sulfate, usually five to 10 pounds per acre, and manganese sulfate is also applied to the soil at rates of from 20 to 150 pounds per acre. Manganous oxide is also used to correct manganese deficiencies. In alkaline soils an acid-forming material, usually fertilizer, is applied to prevent fixation of the applied manganese—NH4+ applied, H+ released. Zinc is often sprayed on the leaves of apple and pear trees to treat ‘leaf rosetting’, a symptom of zinc deficiency. Approximately 25 pounds of zinc sulfate in 100 gallons of water (roughly a three per cent solution) applied to apple trees just before the buds open has been shown to correct this condition. Zinc sulfide, zinc oxide, and zinc carbonate have all been successfully used as sprays, while driving galvanized (zinc-coated) nails in trees is

136

Maximum Yield USA | June 2011

also an effective solution. Boron, as boric acid or borax (sodium tetraborate), has also proven to be effective as a foliar spray. Internal ‘cork’ in apples has been controlled by spraying the foliage with eight pounds of borax in 100 gallons of water, and as little as two pounds of borax per 100 gallons of water has checked ‘cracked stem’ in celery. Boron has also been satisfactorily applied to the soil, either alone or in mixed fertilizers. Copper deficiencies have been controlled by spraying leaves with a mixture of eight pounds of CuSO4 plus eight pounds of Ca(OH)2 in 100 gallons of water.Without the calcium hydroxide, though, the copper sulfate will injure the foliage. Copper oxide has also been used successfully as a spray. Molybdenum, as sodium molybdate, has been shown to eliminate deficiency symptoms in citrus trees in a solution of one ounce to 100 gallons of water. Like iron, however, molybdenum does not seem to be readily translocated within the plant, and spraying only the lower

half of a citrus tree exhibiting molybdenum deficiency did not cure deficiency symptoms in the upper half of the tree. In highly acid soils molybdenum is sometimes fixed in an unavailable form, which leads to deficiencies, particularly in legumes. The amount of molybdenum present in soils and the amount required by plants to flourish is very small, and in addition to a sodium molybdate soil application of 0.5 to two pounds per acre, a commercial seed-coating preparation

How By Beth Dumey and Steve Goldberg

Keep Your Yields

Thriving With Optimal

Indoor gardeners often have questions about pH test strips, testers and meters. Which are best? How long do they last? How do you keep them functioning? Those questions and more are answered.

For hydroponicists, pH level is an indicator of how well their plants are able to access and absorb the nutrients necessary for them to thrive. ‘pH’ refers to the potential hydrogen-hydroxyl ion content, and is measured on a scale that ranges from zero to 14, with values below seven referred to as acidic and values above seven as basic or alkaline. The scale is logarithmic, meaning that a reading of 6.0 is 10 times more alkaline than 5.0. When the balance of hydrogen-hydroxyl ions shifts, nutrient absorption can suffer. Too much hydrogen in a solution and it becomes acidic—the solubility of phosphoric acid, calcium

140

Maximum Yield USA | June 2011

and magnesium declines with pH values below 5.0. Too much hydroxyl and a solution moves toward alkalinity. With a higher level of alkali (above 7.0) some of the nutrients precipitate out of the solution, which means iron, manganese, copper and other elements may stick to the side of the reservoir or settle at the bottom, making them unavailable to nourish the plant. In general, maintaining a pH range between 5.0 and 6.0 is ideal, though some vegetation can flourish at a 7.0 level. Inappropriate pH levels can also influence the development of parasites such as fungal diseases. The combination of inefficient

nutrient uptake and the presence of parasitic fungi can adversely affect the hydroponic growing process by reducing yields and increasing input costs. The pH level in your solution may fluctuate over time as well. In daylight, photosynthesis enhances hydrogen levels, which lowers the pH. In the evening hours an increased rate of respiration depletes the hydrogen ions, so pH levels rise. Regularly testing pH levels and adjusting the solution accordingly will ensure that your plants are receiving the full amount of nutrients required for healthy growth.

Measuring pH

Several resources are available for pH testing:

pH paper strips or liquid test kits

pH meters

These are electronic instruments that provide a more accurate readout—usually digital—of pH levels, and are part of a full pH measurement system that will also include an electrode (or sensor) with an ionselective pH-sensitive membrane, a temperature sensor and at least one calibration solution of known pH. Once calibrated (and adjusted if necessary), pH meters will display accurate and reliable measurements.

Pocket-sized pH meters (also called testers)

These budget-friendly testers are small in size, easy to carry around and run on batteries. Users simply dip the tester into

Gardeners often use inexpensive and convenient pH paper strips or liquid test kits to measure pH, with varying levels of success. With the strips, a test paper is dipped into a solution and the resulting change of color, when checked against a color chart, will indicate the pH level. Paper strips offer relatively low accuracy, however, providing only a rough indication of pH range. Liquid test kits work in a similar fashion, with a dropper dispensing liquid dye into the solution, and provide a higher level of accuracy than papers.

Maintaining electrodes for pH testers and pH meters

Handling

Handheld, portable pH meters These typically offer more features than testers and are good for both in-house and field use. Like the pocket-sized pH testers, they may contain non-replaceable, replaceable or custom electrodes.

Benchtop pH meters Instruments of this kind are available, but are typically used in stationary laboratory applications rather than for hydroponics. Benchtop meters, though not very portable, offer more robust data management capabilities than other meters. For hydroponic applications, pocket pH testers or handheld pH meters are generally preferred—because of their low cost, portability and ease of use.

142

Maximum Yield USA | June 2011

Replacing/refilling When adding filling solution to the electrode, fill up to—but not past—the refill hole. When measuring, leave the refill hole open for proper flow through the reference junction.

Storing

Always keep the pH electrode moist by storing it in four M KCl solution. If four M KCl is not available, use a pH four or seven buffer solution. DO NOT store the electrode in distilled or deionized water. After storage, if white KCl crystals have formed outside the electrode, simply rinse the electrode and blot dry with a lab wipe before use.

How to Keep your Yields Thriving With Optimal pH

“Both pocket-sized pH testers and pH meters use electrodes as sensors.“

Short-term use or longerterm investment?

From disposable paper strips and liquid test kits to meters of various levels of complexity, the lifetime of pH measurement devices varies greatly, but most of the meters or instruments on

the market today are durable and longlasting when used properly. Both pocket-sized pH testers and pH meters use electrodes as sensors. The life of the electrode will depend on many variables, including how it is handled and maintained and what type of sample it is used in. If it is used frequently to test the pH of dirty fluids that are likely to clog the reference junction, the electrode may only last a few weeks to a few months—but if testing is done less frequently, and with relatively clean fluids, the lifetime of the electrode may extend to six months, or even to two years and beyond. Another component of pH measurement systems that must be used regularly is a calibration solution. Only about .6 to 1.5 ounce amounts of solution are required (and later discarded) for each calibration. When purchasing calibration solution, consider shelf-life and expiration dates—calibration solutions usually expire one to two years after their date of manufacture when they remain in sealed containers. Once opened, they should be replaced within 30 to 60 days. Users will need to have at least one pH calibration solution of known value, but should select a buffer value near their expected measured values. If two buffers are used to calibrate, those values should ‘frame’ the expected measured values, meaning most hydroponicists should calibrate with a value of four pH, seven pH or both of these buffers.

Correcting pH

Once a pH reading shows that a solution is either too acidic or too alkaline, the gardener must step in to adjust pH levels to stabilize the solution. Simply put, acids or alkalis should be introduced to the solution at this stage to bring it closer to the optimal range. Hydroponics controllers are available to automate this process, but dedicated hydroponicists can also explore other methods to minimize pH variations and keep their crops flourishing.

Sustainable Food systems 101

What are they?

What are the main obstacles and effects?

Sustainable food systems: • produce diverse, fresh, and nutritious foods. • yield enough to feed everyone, regardless of income level or geographic location. • enable farmers to financially support themselves. • maintain soil fertility now and for future generations. • utilize methods that are not harmful to our environment. • foster healthy eco-systems and biodiversity.

Obstacle: Prevalence of chemicals, synthetics, hormones, antibiotics and geneticallymodified organisms in farming.

Inefficient distribution channels.

What are some solutions? Education • Learn more about the issues surrounding our food supply and spread the word. • Teach children the environmental and nutritional value of sustainably-produced foods with hands-on programs or community/school gardens. Local, organic farming • Buy organic when possible. As demand for sustainablyproduced foods increases, prices will decrease and become more accessible. • Support local economies and farms by buying direct at farmers’ markets, through Community Supported Agriculture (CSA) delivery programs or from co-ops.

Government subsidies to agribusinesses that use chemicals, antibiotics, synthetics, hormones, GMOs, and other controversial substances. Large, vertically-integrated companies that grow, process and package foods.

Unregulated global trade. Fewer, multinational companies controlling the majority of the world’s food supply.

•

Reduce chemicals and GMOs in our farmland by helping conventional farms learn about organic farming and how to transition to sustainable methods Conscientious businesses • Support stores and restaurants that sell or use foods from local, sustainable farms. • Innovative distribution models • Reduce the number of middlemen between farmer and consumer. • Help small, family farms consolidate resources for more effective marketing, sales and delivery. • Develop programs that help lower-income people access affordable, quality foods. • Follow the lead of new distribution models that have proven successful abroad, such as farmer-owned retail co-ops and government incentives. Non-profit organizations • Support non-profit organizations that progress the movement via research, resources, new programs and immediate community change.

148

Maximum Yield USA | June 2011

Effects: • Contaminated fresh water supply from pesticide runoff and excessive animal waste from factory farms. (The number one urgent health issue according to the United Nations). • Creation of dead zones in our oceans from chemical runoff. (The number one top environmental threat according to the United Nations). • Chemical residues on produce that lead to illness and disease. • Degraded soil fertility. • Increased human resistance to antibiotics. • Unknown danger of introducing genetically-modified organisms into our food supply and natural habitats. (Studies have shown that 60 to 75 per cent of produce in supermarkets is genetically modified. • Numerous middlemen between farms and the final consumer, deeply cutting into the profits of the producer. • Inability of small, family farms to effectively supply their customers. • Global hunger—international studies have shown that world hunger is not so much an issue of food production as it is an issue of access. • Promotion of farming practices that are harmful to us and the environment. • Difficulty for small, local farms that practice conscientious methods to be financially viable. • Decreased crop diversity—recipients of subsidies are often required to switch from biodiverse crops that thrive in their particular region to fewer, conventional crops for large-scale export. Mono-cropping also degrades soil fertility. • Commodity prices set at artificially low levels by companies that have financial reserves to do so. (Their income comes predominately from processed goods). • Non-integrated, smaller farms forced to match the same low price, eventually being forced out of business or bought by their corporate competitors. • Replacement of conscientious stewards of the land with large agri-businesses, which mostly use unsustainable farming methods. • Fewer farmers responsible for larger areas of land. • Fewer types of produce—varieties are chosen for their durability and shelf-life. Agri-businesses strive for maximum output and lowest overhead. • Food traveling an average of 1,500 to 2,500 miles and seven to 14 days to get to your plate. • More fossil fuels used in transportation. • Decreased food nutritional value.

• •

Revised government policy.Vote for politicians who support a sustainable agricultural industry. Sign online petitions for food and farm reform. MY

Maximum Yield sits down with Scott Bogner, director of operations and chief operating officer at Sero Systems, to discuss their new and advanced breed of environmental controllers, the difference between digital and analog monitoring and exciting plans for the near future.

Maximum Yield (MY): What is the history behind Sero Systems? Scott Bogner: Sero Systems was formed because one of our board members has a winter greenhouse that she operates and she needed some environmental control for it. She wasn’t overly excited about the options that were in the market.We had about seven years experience with control systems so we set out to design a new breed of environmental controller that wasn’t the same old, same old. MY: What is the GrowPak and why should indoor gardeners be excited about it? Scott: This new system is an amazing blend of functions and features available at a very competitive price.We worked to make our controller accessible to everyone in terms of price and usability.We packed in a ton of features and are continuing to develop new things for this system. So you’re not just buying a controller, you’re buying a system that will grow with you and the industry. MY: What is the GrowPak capable of? Scott: That’s a tough question because it can do so much! I’ll start by running down the list of what it can monitor such as temperature, humidity, pH,TDS and CO2. It can also control lighting, pumps for ebb/ flow, heaters, AC units and just about thing you plug into the wall.The system can send e-mail or text messages when your set-up

has an issue.The GrowPak S1 also combines functions such as temperature and lighting to help run your set-up more safely.The list really goes on and on.

MY: What types of inputs and outputs do indoor gardeners need to be concerned with? Scott: Another great thing about this system is that it’s modular.This means you can build the controller you want. Customers can monitor whatever they want, whatever is important to them. Whether you’re working with hydroponics or soil, you’ll find this system is able to handle what you’re working on. In terms of I/O we have all the basics covered like pH, temperature,TDS, humidity and CO2, but we also have contact switch monitoring as well as e-mail and Internet access if you want it.

the GrowPak such as sensors and probes for all the stuff our system does.We like to offer a complete solution.We’re also an innovative company and are always looking for ways to expand our product line, so who knows what the future holds. MY: Who are the names and faces behind Sero Systems? Scott: Let’s see…we have over 100 years of engineering experience on the team. We have leaders from the microcontroller industry, we have new grads and overall we have a very stellar team that really enjoys and believes in what they do—creating innovative products.

MY: What are the benefits of digital monitoring versus analog? Scott: Digital monitoring allows for better calibrations; it allows for a more advanced level of integration with control features across a wide array of control functions. That’s just not something that older analog systems can do. It’s also the future in that digital systems are getting more affordable.

MY: What is Sero Systems’ role in actively supporting local causes and community building? Scott: Another great question. Maybe Maximum Yield and your readers can help with this.We feel very strongly in getting involved in our industry.We are always looking for school projects, local clubs and other opportunities to participate in organizations that are working to educate and expand the industry as whole. If you know of, participate in or lead such a group please get a hold of us we’d love to see if there’s an opportunity to join in.

MY: What other products does Sero Systems offer? Scott: Because our system is modular, we offer a full compliment of accessories for

MY: How can gardeners stay connected to Sero Systems and learn about new products and promotions?

Scott: Sero has launched our Facebook page as well as started on online e-mail list for keeping up with all the new things we’re rolling out over the next six months. MY: What can gardeners expect from Sero Systems in the future? Scott: In our minds the control market is full of the same old, same old.We’re looking to change that and really help take the indoor garden industry to a new place in terms of technology and features. There’s so much out there that we can take advantage of, so much technology that will make growing easier and help keep you in control of your overall system. In fact, we have a module called the TechPak that lets your GrowPak S1 get online, and it allows you to not only e-mail, but it will allow you to do some pretty neat things from your computer and allow you to interact with your system from a distance. Another thing that we’re working on wrapping up is the GrowPak S2 system. Where the GrowPak S1 is a great entry level system doing everything you really need, we do see that there is room for more.The GrowPak S2 (not yet announced) will give growers even more features and functions with a great interface. We’re a very forward looking company and really want to offer customer easy-touse, feature-rich advancements, all for a price that doesn’t break the bank. MY Maximum Yield USA | June 2011

a lot more important than most gardeners realize.With a container it is all too easy to compact compost. Look at a container that has been standing for two or three years. It looks as if it has shrunk. The sides of the compost are usually pulled away and the level has dropped from the top. So much so that when it is watered it runs straight down the sides and out of the container, hardly adding any moisture to the compost at all. It is compacted and over time has dried out too many times.

“Regularly top dressing of even replanting in fresh soil-based compost is essential.” Another rule to practice is regularly top dressing or even replanting in fresh, soil-based compost is essential. The full potential of the display will be realized and make it worthwhile when the neighbor asks why yours looks better than hers. The compost can be soil or soilless based and should be ideal for all displays apart from acid lovers like heathers, ferns and dwarf conifers. Soil based composts add weight, which prevents wind from blowing the displays over and acts as a benign barrier to hold on to water and nutrients. Add some moisture retaining material—either moss, gel or even waste substitutes. These will act as reservoirs, releasing moisture as the plants need it. Slow release feed is a great standard option and I also recommend using a boost feed at the start of flowering. A foliar feed will be more useful as long as you do it when watering in the early morning or in the evening. Watering at any other time and you may run the risk of water spots and burn marks. Another rule to abide by is when you have planted up the container always put some seed on top; it will develop and fill in as the original slows down, thus keeping that fresh look longer into the season. Planting in containers is a very personal thing.Your baskets and tubs will inevitably reflect your choices in color and style.

others will stick to just a one color theme. Both are acceptable as long as it looks right to you when your plants are fully grown. My ideal container is a 12 inch fuchsia mossed-up basket, marinka around the sides with blue lobelias using fuchsia Winston Churchill as the king plant in the middle. The new giant fuchsias also make a beautiful display, with just three young plants filling a 12 inch basket easily. When selecting the plants for your containers think of how you view them. Do you want to be able to look down on your plants, like verbena? If so put them in low tubs. Do they look better from a height like trailing Busy Lizzie? If so place them in half baskets and hang them at eye level. Don’t feel like you must always group containers sideby-side. Explore design using them in a waterfall scheme to achieve height and impact. Progressive larger pots, one inside another, will clothe quickly and be easier to water and feed as well as look great as columns on a patio. MY

Knowledge is power. One-stop-shop. Guaranteed customer satisfaction.

Cliché as they may sound, these principles are embedded in America’s Best Hydroponics and Garden Center’s daily philosophy and its keys to its success. “Our goal is our name,” owner and founder Paul Antriasian said.The number of hydroponics stores that have opened over the last five years has almost doubled.With an increase in competition, the spotlight has been put on “store survival.” As Sir Francis Bacon said,“knowledge is power” and nothing is truer for survival in an industry that is vastly and quickly expanding. America’s Best constantly strives to be ahead of the curve with product knowledge and trends and also in educating their customers. “Knowing hydroponics systems and products and how to set up a grow room is the key to growing successfully—we help you through the entire process,” Paul said.“We constantly test new products and give customers samples to try and request their feedback. It’s a network.” America’s Best Hydroponics and Garden Center and its employees are continually educating themselves. “Always reading, trying new products, talking to manufacturers, attending grow shows,” Paul said.“…myself and all my employees.” “I have personally used all the products I carry and I know they work,” he said.“We want to make sure the customers are educated and comfortable using the product before they leave the store.” “We pre-program and calibrate all of the pH and PPM meters before we sell them,” Paul said.“We have custom nutrient/grow room charts that show all the nutrient and grow room high/low parameters to help keep the PPM, pH, air temperature, water temperature, CO2 levels and humidity at the correct levels for optimum growth.We always have up-to-date catalogs, magazines, feeding charts and various literature for the customer to take home with them, for free, to help further their education.” America’s Best is known for their helpful and experienced staff. “Word around Antelope Valley is we love to help,” he said. “If you educate the customers and help them reach a successful crop, they will come back and bring their friends!” In 2005, with the encouragement of friends—many of whom Paul introduced and educated about indoor gardening—Paul opened the first hydroponics store in

MERICA’S BEST the Antelope Valley, Palmdale Hydroponics. “They told me I was a true pioneer of hydroponics,” Paul said. Paul’s experience with growing started long before he opened Palmdale Hydroponics.With a father who was an engineer as well as a landscaper and mother that was a “plant fanatic” it was only natural that Paul became interested in growing. In high school he took horticulture and continued growing outdoors for seven years before starting with indoor gardening. “In 1988, I started growing indoors,” Paul said. “The first hydroponics store to open in the entire country wasn’t far from my home. It was there I received my first lessons in hydroponics and bought everything I needed to start my own hydroponics system.” For the next 18 years Paul developed his expertise of indoor gardening. His passion for horticulture and expertise in hydroponics leads him to believe that hydroponics is the way of the future. “When hyperinflation hits the U.S., this is when you will start to see hydroponics systems in every home,” he said.“Like the computer, this will be a modern tool for everyday living.” Hyperinflation increases the prices of all food products forcing people to purchase inexpensive low quality processed foods, which in turn leads to an unhealthy population. Hydroponics can help combat this. “Many of the fruits and vegetables we consume are being waxed, died, sprayed with pesticides and exposed to radiation, which is extremely harmful to humans and the environment,” Paul said.“This is just another reason why everyone should learn hydroponics.” When Paul opened Palmdale Hydroponics, he was the sole employee for the first year. In 2007, Paul’s fiancée,Victoria Wouk came on board. “Her master’s degree in business administration and marketing has really helped the business expand to other avenues,” he said. “In 2009 we launched our online store HydroponicsUnlimited.com, which she runs.”

At the beginning of 2010, Paul moved to a new location that could better serve their clientele and customers. “We moved to a 3,000 square foot location with a roll-up door for easy loading,” he said. “We felt that this new fullystocked location (one-stop-shop) deserved a new name and decided on ‘America’s Best Hydroponics and Garden Center’.” With the launch of the website America’s Best Hydroponics and Garden Center created an additional avenue to offer their products and expertise to their customers. The online store allows them to reach customers throughout the United States and give them the same benefits that Antelope Valley locals have been receiving since 2005. The online market has become saturated with new stores opening all the time, but America’s Best Hydroponics and Garden Center remains optimistic that quality will beat quantity. “Online is the future,”Victoria said. “It’s a marketplace that you need to be in these days.” America’s Best Hydroponics and Garden Center has over 2,800 products, many demos and interactive displays, a convenient location, an online store and new and innovative products. As written on their website, “…whether you are a beginner or experienced, growing hydroponics herbs on the windowsill of your apartment or operating a full-service hydroponic greenhouse we have what you need from organic nutrients, additives, supplements, grow mediums, to a full range of bulbs, meters, controllers and complete grow systems.” It comes down to integrity, honesty and hard work that have contributed and will continue to contribute to America’s Best Hydroponics and Garden Center’s success and growth. “This is an extremely difficult business,” Paul said.“You really need to do your research and know what you are getting into. You just have to take it one day at a time, always moving forward and making progress. One thing for sure is you have to love a challenge.” America’s Best Hydroponics and Garden Center is located just off Highway 14 on Palmdale Blvd. tucked behind a main shopping center. The new location atThe 3,000 sq. ft. location houses tracts to new customers, makes it easier more than enough product to keep customers well stocked. for customers to load and receive their products, and since it is not on the main boulevard, this decreases traffic and allows for plenty of parking space.

Introducing the Humboldt Micromole Lumens are for humans—for plants it’s all about the micromole. The standard measurements of light output have traditionally been done in foot-candles, lumens or lux. They only quantify how humans experience the brightness of light. Plants, however, use a much wider spectrum of colors for photosynthesis called the PAR spectrum (photo-synthetically active radiation). Photosynthesis is not driven by the brightness of light, but purely by the number of photons hitting your favorite crops. This is measured in micromoles. Research and development for the Humboldt Micromole electronic ballast was done to maximize PAR light. With dimmable features, the SuperMole setting gives your plants 15 per cent more usable light and will send your micromole reading off the charts. The Humboldt Micromole is now available at indoor gardening retail shops across the country.

Old Fashioned Crops are Making a Comeback With a renewed interest in the culinary arts and gardening in general, we are seeing a resurgence of some old crop favorites and finding many of these are well suited to indoor and hydroponic production.

Companion Planting in Hydroponics

Companion planting outdoors is a popular gardening trend, but in a hydroponic garden, it’s a whole different game. Pay attention to these fresh tips and success and great yields will surely result.

The Great Organic Hydroponic Debate

Many hydroponic growers wish to apply organic components to their garden, but the process isn’t so simple. Find out what’s organic and what’s not and how these two concepts—hydroponics and organics—can work together under today’s certification standards.
