Maximum Yield Canada | July/August 2013

FROM THE EDITOR | Linda Jesson Fifteen years ago, the first issue of Maximum Yield was devoured by a Canadian indoor garden industry hungry for information about techniques and products that would help them grow. Demand for such information grew steadily, and Maximum Yield quickly spread to the United States and eventually to the United Kingdom, Australia, New Zealand and most recently, Europe. The issue you are holding now marks our 15th anniversary issue, and we are thrilled to celebrate this milestone with our readers. To learn more about how we came to reach this publishing milestone, be sure to read our 15th anniversary special feature on page 64. July and August can be hot and in this issue from the you will find great reads about finding and maintaining success in your summertime garden. We talk about why it’s important to get your soil tested every now and again, and Linda Jesson also about how much water is too much water to be adding to your garden. Check out how common physiological disorders can strike even the best green thumbs. Also, in our guide to beneficial bugs, we pair up which bugs are the best at battling those pests most harmful to your plants. We’ve paired these great features with a nice selection of new product profiles and some fun Max Facts to round off this anniversary issue. For those of you that missed the most recent Novi, Michigan, Indoor Gardening Expo, we want to invite you to the upcoming 10th Annual San Francisco Indoor Gardening Expo taking place on July 28, 2013. This will be our biggest show ever and will include over 400 exhibitor booths. Education stations, networking, samples and more will all be a part of this highly anticipated expo. Please visit indoorgardenexpo.com for all the details. Finally, we want to personally thank all of those who have helped up reach this special milestone celebrating 15 years in the industry.

Friendly Facebook Tips We recently asked our Facebook fans: “What was the first crop you ever grew successfully, and what was the experience like?” Here’s what people said:

Jessica Amanda Anderson

“When I was five, I planted lupins in my front yard of my old house with my mom and they are still there today! They grew every year and were beautiful, I was so proud.”

Hydrolight Wholesale staffer

“I remember planting tomatoes with my grandmother (God rest her soul) as a child. She was a real-deal Italian mother who had the green thumb. She did lots of canning of all sorts and was a beautiful woman. She had fig trees, plums, apples, apricots, grapevines and all kinds of vegetables. [Those were] good days as a kid growing up on the east side of Detroit in the early ’80s.”

SIMON SAYS simon says

Simon Hey Simon, I have a problem with spider mites (seems like a common problem). I was thinking of cranking up my carbon dioxide levels to 10,000 ppm with my CO2 monitor to try and eradicate them. Would it work? Increasing the carbon dioxide levels to that completely unnatural concentration might actually be effective since I think it would be exceptionally hard for them to breathe. Of course, the danger of this is it would also be extremely harmful to people in and around the area. Even if you exhaust the room into a different area, the concentrations would still be highly elevated. I seem to remember talking to a scientist who mentioned that extreme levels of carbon dioxide can become phytotoxic, but I can’t recall exactly who gave me that information and I am not sure of the mechanism. Personally, I would not recommend the method you suggest. Spider mites are a severe problem for many indoors gardeners and there are various methods that can be efficacious at keeping these pests at bay. • Keep your growroom clean. This point can’t be stressed enough. If you are a serious gardener, your growing area should be tidy and free from debris. Also, avoid bringing problems in from outside by having air filters on your intake, and also consider wearing clothing just for the growroom. It might seem like overkill, but consider how meticulous commercial greenhouses are. They understand that in an unnatural environment, the introduction of a pest can quickly spread out of control, so prevention is the best solution. • Be vigilant in your garden. Once a spider mite problem is detected, isolate the affected plants if you can move them, and then segregate them with a divider. Be sure to move them away from your other plants and try to reduce the amount of air movement around the affected plants. 12

• Chemical options are still available and can be effective. You will need to read the product’s label. All of it. Many of these products are exceptionally harmful if not applied exactly as recommend and licensed by the manufacturer. Their major downfall? Insects build up resistance far more quickly than humans because their lifecycles are shorter. This means that the spray that was very effective last year will be less effective this year. Use a rolling system of a variety of options to minimize the buildup of generational resistance. • Go the organic route. We all know I love organics and I will continue that trend for this answer and remind all readers that there are many organic alternatives now. Neem-based products have been leading the way for years, but now we have all sorts of plant extracts and essential oils that can impede the super web from forming in the middle of your crop. Note: if you have webbed super highways between plants, remember that dismantling them and squishing them with your thumbs (physical removal) can actually do a great job at decreasing the population prior to using an insecticide (chemical or organic). Be sure to clean your hands properly after since you don’t want to move mites so they can come back later. • Try using nature’s solution. I can remember always telling clients in the shop that if I had a problem with gazelles in my backyard I would probably buy a lion. It’s a bit of a stretch but that was my pitch on beneficial insects—nature has a solution. Commercial greenhouses around the world use predatory insects as their primary method to help mitigate pests. Most of these insects are available to home gardeners as well. In this case there are a few types of mites that eat spider mites and there are more options on the horizon. For those of you that are not convinced on beneficials, consider these points: 1. Commercial farmers don’t use things that don’t work. 2. If you have a million mites in your room, buying 1,000 predators will not help you since they can only eat a certain amount everyday. 3. For large gardens the best approach can sometimes be to buy a bulk supply of predators prior to an outbreak. This acts as a pre-emptive move that can inhibit an explosion of the spider mite population. This can be a good insurance policy on short-cycle annual plantings but is less effective in a perennial situation. So, first you spot your mite problem by spending time in your garden, observing and noticing the issue early. Then you isolate your plants from further contaminating your crop. Try to physically knock down the population then apply a pesticide, organic if possible. Order your beneficial bugs and apply them as soon as they come in. Be vigilant with the remainder of the plants to make sure you have quarantined the mite population.

Curing Cataracts A study suggests that certain antioxidants found in spinach and greens seem to protect against cataracts, which are common in Canada and are the result of a clouding of the eye lens that is linked to oxidative stress. This occurs with age as the lens is exposed to pollution and ultraviolet radiation. Researchers have revealed that lutein and zeaxanthin, two antioxidants found in green leafy vegetables, can protect against cataracts. So, if you want to protect your vision, it may make sense to step up your intake of kale, spinach and greens. (Source: newsfix.ca)

hydroponic news, tips and trivia Greenhouse Growers Applaud Tax Relief

Counting Cucumbers Once a specialty greenhouse crop, Ontario greenhouse-grown Persian (mini) cucumbers are now available year-round, and retailers require these bite-sized cucumbers to be sold in 1-lb pre-packaged bags or trays. The challenge is that this sweet flavoured, crunchy fruit grows naturally in different shapes and sizes. Currently, the proper sorting and packaging of greenhouse grown mini cucumbers is done manually, and workers must judge by eye, but Tug Weld Manufacturing has designed a sophisticated solution with their Persian King Air Touch Mini Cuke Size Grader. It’s estimated that labour-intensive packing needs 40 employees to grade approximately 50,000 mini cucumbers manually per hour, while the Persian King Air Touch is able to easily process 30,000 cucumbers per hour while requiring only four to six operators.

The provincial government of British Columbia is providing $7.6 million in carbon tax relief for greenhouse growers, which is an amount that correlates with the amount of carbon tax the province’s greenhouse growers pay in a year. “The bottom line is BC growers will be able to better compete with producers in the US and Mexico as a result of the carbon tax grant,” says BC Greenhouse Growers’ Association president Peter Cummings. (Source: chilliwacktimes.com)

Creating an Organic Platform The Platform for Innovation in Organic Agriculture in the planning stages in Quebec is aimed at strengthening growth in the province’s organic agriculture sector by improving not only the competitiveness of producers, but also the environmental performance of farms. It’s a platform for research and development, knowledge transfer and training in organic crop production, which will take place in an open-air laboratory with a range of exclusive, state-of-the-art equipment and services that are not available elsewhere in Quebec or in Canada. “The new infrastructure will support the organic agriculture industry by accelerating the discovery and application of solutions that meet the needs of farmers and Quebec companies working in this sector,” said the Deputy Premier of Quebec and Minister of Agriculture, Fisheries and Food, François Gendron. The Platform will benefit companies certified in organic production, as well as those in the process of converting to organic production. (Source: agr.gc.ca)

Northern Food Rescue Program Twice a week in Whitehorse, individuals from the Boys and Girls Club of Yukon visit local grocery stores to pick up all the food that is near, or has just reached, its best before dates. Normally this food would be thrown away, but instead it is used in soups, casseroles or whatever else can be made. To offset the costs of a program such as this, the Boys and Girls Club of Yukon has begun a social enterprise called the “Northern Food Sustainability Project” that includes the growing of micro-greens, spices and vegetables that are then sold to the community.

Smelling Strawberries New research has unveiled what gives strawberries their characteristic flavour. The characteristic aroma of a fresh strawberry is the result of around a dozen different aroma compounds. One of these plays a particularly important role: HDMF (4-hydroxy-2,5-dimethyl-3(2H)-furanone), which is also known under the brand name Furaneol and also found in pineapples and tomatoes. A ripe strawberry has a particularly high concentration of this compound (up to 50 mg per kilo), which lies far above the odour threshold. This compound gives the ripe fruit its characteristic caramel-like aroma. (Source: sciencedaily.com)

Orangutan Apples In an orchard in Kentville, Ontario, there are six unique apple trees growing fruit called orangutan. Yes, like the primate. The reason for its unusual name? It has a tangy, citrus flavour like an orange, and the bushy branches of the tree hang like the swooping arms of its tree-climbing namesake. Few people have tasted the orange-yellow flesh of this medium-sized apple, whose orange blush may baffle some. The new fruit tree was first crossbred in 1985 and it took five to 10 years for it to produce fruit. Over the next 10 years, the apple underwent tests focusing on storage capabilities, taste, disease resistance and commercial rootstock potential. The orangutan is now available for grower licensing, meaning nurseries and apple farmers can apply to grow it, but you won’t see it on any store shelves for awhile. (Source: freshplaza.com)

Greenhouses Keep Growing In the past two years, growers in Ontario have increased the total greenhouse acreage in the region by more than 16%. Greater awareness of healthy eating habits has caused the consumer demand that’s driven the expansion in acreage. According to George Gilvesy, general manager for Ontario Greenhouse Vegetable Growers, the total acreage for the region has increased by 353 acres from January 2011 to January 2013. “There are very good climatic conditions for greenhouse vegetables here,” said George. “Ontario has the most sunlight hours in all of Canada.” Because of that, and rising demand, he added that the future looks bright for Ontario’s growers.

From Oilsands to Biofuels The federal Canadian government, an oil giant and a biofuels company are teaming up to build a plant in northern Alberta that will use carbon dioxide emissions from the oilsands to help turn algae into products such as fuel, fertilizer and livestock feed. The plant will be built at Canadian Natural Resources Ltd.’s Primrose South oilsands project near Bonnyville, Alberta. Toronto-based Pond Biofuels’ technology essentially feeds carbon dioxide emissions from smoke stacks—whether it’s at an oilsands site, coal plant or factory—to algae. Waste heat and water from Canadian Natural’s operations will also be used to help the algae grow. (Source: edmontonjournal.com)

Too Many Biocontrol Agents Keeping it simple is a good rule of thumb when designing biocontrol programs to combat weeds and invasive plants, according to University of British Columbia biodiversity experts. Biocontrol programs use an invasive plant’s natural enemies (insects and pathogens) to reduce its population. Most biocontrol programs combine many different enemies (typically about three different species, but sometimes as many as 25) with the hope that at least one will prove effective. But more isn’t necessarily better, say researchers. Some combinations of enemy species can actually end up competing or interfering with each other, instead of attacking the weed.

Maximum Yield Canada | July/August 2013

by Lee McCall

Container, raised bed, in-ground and hydroponic techniques may all be implemented in an outdoor garden with great success. Outdoor gardening obviously differs from indoor gardening with regard to the relative balance of certain environmental factors. The benefit of free sunlight cannot be overstated for outdoor gardeners, as proper lighting is a major expense that indoor gardeners must bear in order to produce healthy crops. Alternatively, carbon dioxide enrichment is not possible for outdoor growers—excluding greenhouse operators—and this enrichment serves to increase the overall quality and fresh weight of indoor harvests. For the average residential grower larger plants may be more easily produced outdoors given the space restrictions that are present in indoor residential growrooms, so yields may be significantly higher outdoors. Bugs, on the other hand, are definitely easier to control indoors, since the grower exercises full control over the environment. While filtering incoming air will prevent moulds and bugs from infecting sterile crop spaces indoors, outdoor pest control may be regarded more as an annoying but expected part of the hobby, rather than something that is completely controllable. I have always had to invest more in pest control in outdoor gardens as opposed to indoor ones. While natural controls such as predator bugs, foliar sprays and insecticidal barriers like diatomaceous earth can help to control the pests and diseases that are constantly attacking outdoor crops, larger pests such as moles, rabbits, deer and squirrels will have to be physically restricted through the use of perimeter fencing or other deterrents.

Digging in the dirt The best recommendation I can provide for outdoor gardeners is to first implement a clean water source, free of heavy metals, chlorine, chloramines and contaminants. Carbon, sediment or reverse osmosis purification systems can help to provide a high-quality water source for all the plants in the garden. A quality growing medium and nutritional package will also help to keep growth progressive and consistent. Outdoors, I prefer a growing medium that has dominant moisture-holding capabilities—a rich organic soil heavy in castings, composted forest humus, coconut coir and perlite-grade diatomite will provide this and encourage lush microbial colonization as well. I choose not to add any more perlite than the amount that comes premixed in most organic potting soils and planting mixes, as it tends to increase drainage and encourage drought.

Rich organic soil is ideal for raised bed and in-ground gardens.

Maximum Yield Canada | July/August 2013

The type of rich organic soil I have described above is ideal for raised bed and in-ground planting. Go lighter on waterings if you are not used to incorporating such a heavy moisture-loving mix though, so as not to drown the roots slowly to death. Thorough watering is ideal, but make sure the plants are drying out, or consuming their water weight, between feedings. Aeration containers, whether fabric-based or injection-moulded, are also highly recommended for their root pruning properties and the increased dissipation of heat from the root zone caused from sun scald or high temperatures they can provide. Dose (top dress) raised beds and container gardens once a month with a premium organic granular (dry) fertilizer to ensure the optimal health and vigour of your garden. Specialty blends are available from a wide variety of manufacturers that can provide plants with an immense but safely time-released amount of primary and secondary nutrients, trace elements and bacterial and fungal inoculants. I believe all outdoor gardens should be supplemented with these fertilizers as opposed to synthetic ones, which deplete soils and eradicate naturally occurring microbial colonies. These organic and natural fertilizer packages are relatively inexpensive—approximately $10 for a box or bag—and they will increase the vitality of the soil each time they are applied. This means that a raised bed or garden patch that has been treated this way season after

season will actually increase in microbiological diversity. As the plot, bed or container naturally self-composts over time, nutrients should become more readily available and the soil’s water retention properties will be enhanced. Many people are also not aware that tilling their beds, plots or containers is a misguided practice. Until recently I was also an offender, until several experts educated me on the reasoning behind the principle. Never till the soil! This disrupts the microbial colonization of the beneficial fungi and bacteria that are responsible for the bio-availability of nutrients to your plants. When growing hydroponically outdoors I find myself obsessing over root zone temperatures more than I probably should, although this is a critical aspect of hydroponic gardening—indoors or out—that always tends to give me problems if I neglect it. Water chillers are great examples of innovations that implement technological advancements in order to overcome natural environmental conditions. Heat may no longer debilitate your plants if they are able to maintain cooler root zones from the application of a chilled nutrient solution with high oxygen concentrations. Despite temperatures of 35°C and upwards, certain varietals will definitely tolerate even extreme heat waves, so long as the roots are bathed with a chilled and oxygenated nutrient solution. Outdoors, insulate

Some growers will actubathed with a chilled and oxygenated nutrient solution. ally bury their holding tank partially or even completely in the ground, which insulates the solution and protects it from light. Drip systems—which allow automated handsfree watering over a soilless or hydroponic grow medium using a submersible pump and timer—are easy to implement in most patio or outdoor gardening plots, and plastic tubing and drip emitters are available from most local hydroponic and indoor gardening supply outlets. Recirculating and drain-towaste systems may also be utilized. For water conservation purposes, I recommend soil, soilless or coco-based growing mediums that retain higher levels of moisture. With the growing season in mind, always prepare in advance to have a better chance of success. If possible, start seeds indoors under grow lights so that the weeks of early vegetative growth establishment are already done when the weather finally allows outdoor planting. Use shade cloth if necessary when hardening off transplants started inside so as not to instantly overdose the fragile starts with intense sunlight and too big a change— this is a great way to provide sown seeds a healthy start without overstressing them. You can also use coconut coir chips or croutons as a top dressing to create a decorative, ecofriendly landscaping effect on raised flower beds or garden plots. Large-grade diatomite adds a decorative appeal that decreases insect populations and adds beneficial silicates to the soil as well. As the weather gets warmer and vegetation reappears, we’re back once again to the joy of digging in the dirt in the backyard garden. Promote selfsustainable gardening practices whenever possible—and enjoy indoors under grow the fruits of your labour, comlights so that the pliments of the sun. MY

How Much

Water is too Much? by Frank Rauscher

Maximum Yield Canada | July/August 2013

Should you be watering your plants once a day? Probably not if they’re cacti! In truth, different plants and different soils need different watering regimens. Here’s a general guide...

Too much, not enough, too often or too seldom—these are concerns I hear from growers all the time regarding watering practices. The question most often heard, however, is simply, “How much?” A clearer understanding of the issues involved in watering your plants might help answer this for you.

“The optimal amount of water to apply is the amount you need to adequately saturate the soil to the depth of your plant’s root system.” In regards to how much is too much—when your soil has good drainage, your only real concerns are wasting water and draining off essential nutrients; otherwise, it’s not really an issue. The optimal amount of water to apply is the amount you need to adequately saturate the soil to the depth of your plant’s root system. (If the plant is still in the early root development phase, the soil should be watered to a point a bit deeper than the roots currently exist.) When the amount of water applied is insufficient or the watering time too short, the water does not extend all the way to the depth of the roots—this problem is common with soil that drains or perks slowly, and often results in a plant with shallow roots and poor yield. Soil type has a huge impact on the amount of water you’ll need to provide your garden. No matter what the soil type you’re using, the entire root system should be wet when watering is completed. This process might take some time after the watering cycle has completed, as soil moisture osmosis can be slow and gradual. In heavy soils like clay, a fully wet root ball can take several watering cycles to achieve because the water tends to run off if applied all at once or too quickly. This means that the optimal amount of water your plants require is also tied to the rate at which it is applied. When you apply water by hand, it tends to be applied quickly and conditions of unequal soil moisture are more likely to occur. However, evenly moist soil provides your best chance for healthy root development and the maximum yield from your crop. The easiest way to achieve this is to use slow-drip watering, a process in which runoff is avoided and run time can be ascertained through the use of a soil probe and moisture meter. Although moisture meters are by no means 100% accurate, they do provide a digital comparison between moisture levels at various depths of the root ball. This can add a lot of insight compared to the simple use of an “educated finger” for checking soil wetness.

“Evenly moist soil provides your best chance for healthy root development and the maximum yield from your crop.” Maximum Yield Canada | July/August 2013

How much water is too much?

All this can sound like way too much work in order to figure out how long to water, but it doesn’t need to be. With containers, potting soil is your typical growing medium. It provides good drainage, so if you have applied the water slowly, then the point at which you can observe runoff from the bottom of the container will indicate that you’re done. Then, to determine when to water again, know your plant’s preferences and check your soil moisture periodically. Also, take notes—you won’t have to keep repeating this process if you are using the same containers and medium again. Raised beds might have heavy, slow-draining soils, which introduce a variable of percolation rates and requires that water be applied slowly in order to prevent runoff at the top. Bottom runoff is not visible in raised beds, so a soil probe to examine the deeper levels of soil moisture will be required—in-ground garden beds need this even more. Now, let’s address an even more important issue: how often is too often? Most houseplants need water about once a week, but what about other crops? Watering a plant every day is frequently done, yet rarely debated; and while there are plants that do well

with daily watering, there are many that do not. That’s why I feel a better understanding of watering frequency is vital. The ideal condition of soil moisture for most plants is when the lower section of the root ball does not ever dry out, but stays moist while the upper section remains welloxygenated and only slightly moist. (That being said, drought-tolerant species and low-water users are not tolerant of continually wet soil—their root systems need to have more oxygen present.) Of course, when water is applied from the top—as is normal—then for a time the top section will naturally be the wettest. This is one reason why watering too frequently can cause trouble. Factors such as evaporation, transpiration and soil drainage are all keys to figuring out a good watering schedule that will achieve the ideal soil moisture condition. Evaporation is a function related to the soil and is based primarily on ambient air temperature, wind and surface area. When growing indoors, the air temperature is impacted to a great degree by the type of light source employed and the number of hours that the lamps are run. If you’re growing in a room without air conditioning, then

“The ideal condition of soil moisture for most plants is when the lower section of the root ball does not ever dry out, but stays moist while the upper section remains well-oxygenated and only slightly moist.”

Maximum Yield Canada | July/August 2013

evaporation will increase as the summer brings warmer temperatures. Movement of water from the roots to the stems and leaves before exiting the pores or stoma is called transpiration. High air temperatures, dry air, wind and the type of plant involved all affect the rate of transpiration. When soil moisture is depleted and the roots can no longer pull up enough water, the rate will slow and the plant will start to stress. Leaves will flag or wilt and tissue death will eventually occur. When trying to anticipate how much water might be needed for your plants, it should be apparent that mature plants with large roots will take up and give off much more water than small ones. Vegetative plants also use more water, in order to support production. In other words, you’ll need to increase watering frequency as the plant matures—especially when growing in a container. Different soils also drain or percolate at different rates. Many potting soil products use coconut fibre to help retain water for a longer period of time, whereas other products add sand to help increase drainage and allow oxygen to return more quickly. Succulent plants do well with fasterdraining soil, while bog plants, like horsetail and canna lilies, can have their roots wet all the time. Knowing plant and soil characteristics and then keeping that balance right during the various phases of plant growth is what makes for success. A good balance between the air and water in the root system is also extremely important. Respiration is the process within a plant where oxygen is taken into the roots from the soil and the plant converts the sugars it created during photosynthesis into energy. Without adequate soil oxygen (which can be depleted by overwatering), the roots do not function properly and the plant shuts down. Often the symptoms you’ll observe in this situation are almost identical to those you’ll see when a plant is drying out—the leaves flag or wilt and the plant begins to die. This is why plants will actually die much faster from overly frequent watering than from drought. A comparison might be made with humans—how long can we go without breathing air,

compared to how long can we go without drinking water? Then there are those plants that are drought tolerant; these varieties have adapted to growing in conditions where water might be withheld for weeks or even months. Many of these plants take up as much water as they can when it’s available. So, when given irrigation frequently, these plants often take up so much water that it damages them. There is a big difference between lowwater plants and drought-tolerant species, however; low-water plants just don’t take up water quickly and so will be far less affected by overwatering. Still, respiration is important for all plants and adequate soil oxygen must be assured. So, the age-old question “How often and how much should I water my plants?” does not have a simple one-size-fits-all answer. Depending on plant characteristics and soil, proper watering frequency can vary greatly. The key to establishing an appropriate routine is knowing your plants and your soil. If you understand the interaction between your soil, your plants and the ambient temperature, you’ll have a head start on a good watering schedule. The use of a quality moisture meter can also help in monitoring and maintaining the correct frequency of irrigation. (The amount of dissolved oxygen in the soil is also great to know, but meters that measure this are rather expensive). Follow these steps and, within a short time, your plants will be healthy and vigourous. MY

Physiological

Disorders of Indoor Gardens by Dr. Lynette Morgan Indoor Gardening Allows gardeners to be fully in control of their plants. So, when physiological disorders strike, they can seem strange, mysterious and even sinister… Indoor gardens can be a fairly intense environment for hydroponic plants. High levels of light, heat, carbon dioxide enrichment and a plentiful supply of water and nutrients give plants everything they could want; however, sometimes growth can still go awry with no obvious cause. Physiological disorders, which affect a plant’s development, are usually the culprit, and they are caused by environmental or cultural factors. Some of these physiological disorders, such as tip burn on heading lettuce or blossom end rot (BER) on tomatoes, are common in indoor gardens, large-scale commercial greenhouses and outdoor production, so they are relatively well-understood and easily recognizable. Other physiological conditions, however, are much more specific to the enclosed environment of indoor hydroponic system and are not as well-understood or easily diagnosed by growers. Some physiological disorder symptoms are also non-specific, meaning the same symptom could be caused by a number of different issues—like plant pathogens, nutritional problems or a complex physiological problem. In this case, having a good idea of basic plant requirements and physiology is the best place to start.

Physiological problems in detail Humidity & root pressure issues

Humidity levels—if not kept below a certain level—might be more often associated with an increased risk of fungal and bacterial disease; however, it also plays an important role in plant physiology. The plant must be able to transpire and lose water in order to maintain the transpiration stream within itself. If transpiration is slowed down due to high humidity or lack of air movement (which removes the stale and humid boundary layer sounding the leaf), 40

Maximum Yield Canada | July/August 2013

physiological disorders elements like calcium can’t be transported fast enough to the developing leaf tips and fruit. When this occurs, many inexperienced growers mistake the resulting brown or black tissue of BER—in tomatoes and peppers— and tip burn—on the youngest leaves in lettuce, strawberry and other salad crops—to be a disease. However, it is most often due to a localized deficiency of calcium that develops in the extremities of the plants. In wellrun hydroponic systems, tip burn and BER are rarely caused by a calcium deficiency in the root zone; these calcium transport problems are more commonly found in warmer growing conditions and are usually associated with high humidity. These conditions can be improved by lowering humidity and increasing airflow over the plants to boost the rate of transpiration and, therefore, the flow of calcium out to developing fruits and leaf tips. Calcium transport disorders like these also have a genetic element, and many modern cultivars of lettuce and tomatoes have had some degree of BER or tip-burn resistance bred into them.

Glassiness

Another less well-known physiological disorder related to humidity levels is glassiness, most commonly seen in lettuce, young seedlings and other succulent crops. Glassiness creates patches with a water-soaked, almost translucent appearance on the leaves of plants—and it’s often seen first thing in the

morning and it might disappear later on as the plants warm up. This disorder is related to both high humidity and root pressure, which is greatest at night. Roots can take up excess moisture under the cooler conditions at night and, using root pressure, pump this up to the foliage where it can’t be lost from the leaves thanks to the low rate of transpiration that occurs when temperatures are cool and humidity is high. This condition is usually reversible (with no lasting damage) once good ventilation and airflow are introduced and humidity is lowered. However, if glassiness persists and becomes severe, leaf cells can eventually die and create dead patches of foliage that could then be infected with disease.

Edema (Oedema)

Edema is more common than most growers realize; however, its symptoms are often not correctly linked back to the cause. As with glassiness, edema is caused by an imbalance between the plant’s water uptake and water loss, and develops when root pressure is high and transpiration low. The enlarged cells—which are full of water—divide and rupture, causing a number of symptoms like raised blisters, galls and water-soaked swellings or protrusions on leaves, stems and veins. In later stages, the damaged tissue becomes corky with gall-like formations that harden and darken with age. In mild cases, plants can recover from edema; in severe ones, leaves can curl and become distorted

and foliage will drop in the later stages. It has been suggested that edema is linked to the spectral quality of the lighting, with red light promoting the condition and ultraviolet inhibiting it. Edema, however, is usually controlled or prevented by careful management of the environment by increasing air movement, lowering humidity with high rates of ventilation, using a welldrained growing medium with optimum levels of nitrogen, etc.

Light, temperature and cO2 issues specific to indoor gardens A halo of yellow tissue around this cucumber leaf is a result of high EC in the root zone.

Continuous light injury or abnormal photoperiod effects

Light injury is another physiological disorder often only seen in indoor gardens, where HID lighting can be run continuously or for long periods. Many plant species can tolerate continuous lighting (although running lamps for 24 hours a day might not give the growth increases expected), but some species—including tomato, potato and some ornamentals—are intolerant of extended or continuous periods of light. If exposed to such conditions, they can develop physiological disorders, such as becoming severely chlorotic, yellowed and stunted or with brown flecking of the foliage. High-light injury is also more common in environments where CO2 enrichment is used and it is thought that a high buildup of starch in the chloroplasts might play a role in this disorder.

CO2 injury

Salt burn can be mistaken for plant disease.

Blossom end rot of tomato fruit is a physiological disorder related to calcium transport within the plant.

Maximum Yield Canada | July/August 2013

Enriching an enclosed growing area with CO2 can result in significant growth benefits; however, CO2 toxicity can occur when levels run too high. Some plant species are more susceptible to CO2 toxicity than others, so maximum-level recommendations are hard to define. That being said, optimum ranges for most plants are below 1,600 ppm, more commonly in the 800 to 1,200 ppm range. Sometimes, in indoor gardens, the cause of CO2 toxicity is a faulty CO2 monitor; in that case, the grower would not be aware that CO2 levels are well above optimum. It should also be noted that high levels of CO2 are toxic to humans as well—levels of 5,000 ppm can cause dizziness or a lack of coordination—which is another good reason for keeping CO2 monitors properly calibrated. In plants, symptoms of CO2 toxicity can include leaf rolling or deformation, chlorosis or mottling of the leaves and, in later stages, leaf drop of older foliage.

Gasses as unwanted contaminants

Some of the most severe physiological disorders are caused by gasses that find their way into the growing environment. Propane leaks from heating systems have been known to cause injury to indoor crops, but ethylene is a more common issue. Ethylene is a gas and a plant hormone that can originate from a number of sources, including rotting vegetation, ripening fruit, vehicle exhaust and some plant-growth regulators. However, malfunctioning heating systems and the incorrect use of burners to generate CO2 are the most common causes of ethylene contamination in growing environments.

“Physiological disorders can be easily forgotten and overlooked; so, when a problem starts occurring, it pays not to just assume that every issue is either a disease or nutrient disorder.”

The severity of symptoms depends on the species being grown and the level of ethylene buildup. Some sensitive plants, such as tomatoes, will show symptoms—like epinasty (downward bending of the leaves while remaining turgid), reduced growth and height and, in severe cases, leaf and flower abscission—at ethylene levels as low as 0.05 ppm.

Premature bolting

“Bolting” is the term used to describe the premature elongation of a plant’s compact stem. The entire plant, which is still relatively young and immature, grows upward and forms a flower stalk. Lettuce, other salad greens and herbs can bolt or go to seed extremely early, sometimes while still in the seedling stage. Typically, this occurs when temperatures are higher than optimal, often combined with low light levels or overcrowding. Some cultivars have been bred to have some degree of premature bolting resistance, but this physiological disorder is still a common problem, particularly with lettuce. Prevention is relatively easy, however, maintain temperatures below 25oC for lettuce and other cool season salads, maintain suitably high light levels and prevent seedlings from becoming pot-bound and overcrowded before planting out.

Media and nutrient issues

Overwatering and under watering are the most common causes of physiological disorders in hydroponic crops; however, overwatering is far more common and misdiagnosed than under watering (we all know what a dry root system looks like, after all). Interestingly, overwatering initially looks quite similar to under watering—at least from the top of the plant. Wilting, downward hanging leaves, eventual leaf/bud/flower drop, yellowing and chlorosis are all signs of overwatering. In the most severe cases, epinasty will result because the damaged root systems will have started producing ethylene. Overwatering can be prevented by reducing the frequency and volume of nutrient applied, particularly under cooler growing conditions, and using a coarse, free-draining medium like perlite.

Elephant’s foot

Leaf rolling can have a number of causes including CO2 toxicity.

The root zone can be the cause of other physiological disorders in hydroponics. Some of the most common of these disorders are related to salinity damage and electrical conductivity (EC) buildup. As with many physiological disorders, the symptoms of these might be confusing to new or inexperienced growers; however, they are usually never forgotten once encountered.

Maximum Yield Canada | July/August 2013

physiological disorders

“Overwatering and under watering are the most common causes of physiological disorders in hydroponic crops.”

Tipburn can be common on lettuce and other vegetables under conditions of high humidity.

For example, one condition that is common in pepper plants (other plants can also develop a similar appearance) is elephant’s foot—or, foot corkiness. Elephant’s foot is characterized by a swollen and sometimes cracked area on the stem close to the base of the plant, caused by injury to the stem cells by excessive amounts of salts. It is easy for nutrient salts to accumulate around the base of the plant, particularly where the nutrient is irrigated close to the stem area or when a highly free-draining growing medium is used under lowhumidity conditions. Elephant’s foot is less likely to occur when seedlings are planted deeper into the growing medium and when nutrient salt buildup around the stem is prevented.

Salinity damage

Salinity damage in hydroponic systems is much more common in some crops than others. Tomatoes, for example, are fairly 46

tolerant of high EC and salt buildup, whereas other more sensitive plants like cucumbers and lettuce are not. Cucumbers show a fairly distinctive disorder when the EC becomes too high in the root zone (EC levels of only 3 to 3.5 have been shown to cause these symptoms in some cucumber crops): wilting during the warmest part of the day, fol-lowed by a distinctive leaf halo—a thin band of yellow coloration around the leaf margin. This disorder is more common under warm growing conditions with rapid evaporation from the growing media and high rates of water uptake by the plant. These act to concentrate the EC and salts around the root zone, leading to salinity damage. Salinity damage is common under the warm, dry conditions of many indoor hydroponics gardens where EC levels in the root zone can climb far more rapidly than a grower might realize. In this case, the EC in the feed solution should be dropped right back to adjust for the increased rate of water uptake by the plants.

Fruit malformation caused by low temperatures during fruit set is a condition termed catface.

in conclusion

Physiological disorders can range from mild (sometimes not even noticeable) to severe (causing plant death), so identification of the problem is the key to a quick recovery. Physiological disorders can be easily forgotten and overlooked; so, when a problem starts occurring, it pays not to just assume that every issue is either a disease or nutrient disorder. Most of these physiological conditions are induced by factors that are fully under our control and—in an indoor situation—that means keeping a constant check on light, humidity, temperature, salinity in the root zone, CO2 and heating/venting systems. Luckily, these days growers have the choice of the latest technology for monitoring and adjusting the indoor growing environment so that many physiological disorders can be prevented—using and maintaining the best equipment to monitor CO2, root zone moisture levels, pH, EC, temperature, humidity and vapour pressure deficit, airflow and light levels go a long way to preventing any unwanted growth issues.

According to the Arizona Cooperative Extension, aloe vera has been used medicinally for 6,000 years. The University of Maryland Medical Center states that aloe was one of the most frequently used prescriptions during the 18th and 19th centuries. It’s long since moved out from behind the pharmacy counter and onto the shelves (chances are it’s also freely propagating in a garden near you).

How it works

Aloe is 99% water, and the rest is made up of the important parts that directly affect human healing.”

Even if you’ve never broken off a leaf and spread the thin, viscous, clear liquid over a recent burn, you’re probably aware that the “lifeblood” of an aloe vera plant can cool and heal burns, blisters, scratches and scrapes. Aloe is 99% water, and the rest is made up of the important parts that directly affect human healing. Within that remaining 1%, there are polysaccharides (which help skin grow) and glycoproteins (which suppress pain and inflammation, kick-start the healing process). Union County College offers two ways you can take advantage of aloe vera’s beneficial sap. First, you can try going old school by simply breaking off a leaf and let the liquid run across the burn or itchy area. Or you can boil up something more potent by brewing up the plant’s dried sap and use it—after cooling the liquid—as a washout for wounds. Of course, aloe is so prevalent these days that it’s possible to completely skip the homegrown route entirely— whether it’s because you have a black thumb or simply prefer to let someone else do the work. You can find aloe vera extract everywhere. A short trip to a drugstore, pharmacy or holistic health store will reveal aloe vera in lotion, tincture, face wash, ointment and other products.

Paging Dr. Aloe

burns that were dressed with aloe healed completely in less than 16 days, compared to the 19-day recovery period of those treated with silver sulfadiazine.”

While some non-believers could toss claims about aloe’s “super powers” as bunk, holistic practitioners have touted its benefits for ailments such as diabetes, radiation-related mucositis, epilepsy and amenorrhea. Aloe, as mentioned above, is proven to work on burns. (The latter is according to Wilkes University, where practitioners cited aloe’s “beneficial effects for treating epidermal and superficial disorders and wounds”). University of Maryland cites some interesting statistics about use of aloe on minor burns: In one study, burns that were dressed with aloe healed completely in less than 16 days, compared to the 19-day recovery period of those treated with silver sulfadiazine (the traditional medication prescribed by physicians). Maryland also noted that aloe’s benefits extend to other ailments, as it aided sufferers of genital herpes and psoriasis with anti-inflammatory effects that bested hydrocortisone cream.

Grow your own Aloe vera could be called “easy vera,” as it is one of the most low-maintenance plants you’ll shepherd through your garden. Aloe vera plants require very little water and thrive best in direct sunlight. This plant doesn’t ask for much. A simple potting mix with perlite, grit or sand will serve as a fine home. The Arizona Cooperative Extension notes that even cactus mix soil will work for the aloe vera plant. Make sure the plant’s new “home” has a drainage hole and only water when the soil is dry. Also, while these plants don’t quite enjoy “chilling out,” you can easily move them in from the frost and back out when the sun begins to blaze again. Aloe vera plants make a lush addition to your garden, even if you don’t plan to break off a leaf or two. When the plants mature, you’ll have uniform light green color with fronds that extend up to 1.21 m in length. Just be careful with the soft, but prickly spines around the edges. Invest in your aloe plants and they’ll reward you with a stalk bearing cylindrical yellow flowers in a rosette shape. If you do plan to use your aloe plant for healing purposes, don’t worry that breaking off a leaf will destroy the plant or cause necrosis to set in. Stem wounds and broken roots heal themselves (most successfully under shady conditions).

When you’re ready to buy your seedlings or cuttings, you’ll find them online through a variety of sellers, from massive mass merchandisers to specialty succulent shops. You can also venture out and buy from local nurseries, where you might even get advice on planting and supporting your new in-house first aid. The biggest key to avoiding disappointment (i.e., discovering something you’ve planted is not what you planned on) is to do your research. Buy from trusted vendors, who have feedback and encouraging information on their websites. Pop into your nearby horticultural shop and ask who they buy from or who they’d recommend. Then get growing!

Limitations and considerations Holistic practitioners and DIY-ers alike might both strongly advise you try to take the homegrown route as much as possible, but even a strong contender such as aloe has its limitations. Influential health affiliated organizations such as the University of Medicine and Dentistry of

New Jersey state that pregnant women should not take aloe vera in pill format. Women who are looking to conceive, or are unsure whether they are currently pregnant, should stay away too and find other ways to cool their burns. The University of Colorado Denver also warns a larger group of people against the use of aloe vera in pill format—which can serve as a stimulant laxative—including people suffering from chronic constipation, inflammatory intestinal diseases and kidney disease. UC Denver also echoes the University of Medicine and Dentistry’s warning against pregnant women taking aloe vera supplements, and also adds children under 10 years old to the warning list. UC Denver also warns that people allergic to garlic, tulips and onions might also find themselves allergic to aloe vera, which is considered to be in the same Lillaceae plant family. Also, keep in mind that aloe’s positive health benefits only work for

superficial burns. More intense burns from hot stove coils or boiling water, and chemically induced blisters should be treated by medical professionals immediately. In some cases, there’s just no plant-based option for treating something so severe, especially when delaying care could result in life-threatening infection, blood loss or improper healing. The University of Maryland also notes that while aloe has shown to reduce recovery time by up to nine days for some burns, it should never be applied to an open wound. MY

How to Grow Growing rosemary indoors can be tricky. Many good gardeners have tried and, despite their best efforts, end up with a dry, brown, dead rosemary plant. Knowing the secrets to proper care of rosemary plants grown indoors will help you keep your rosemary plants growing happily indoors all year long.

by Heather Rhoades

Maximum Yield Canadaâ&#x20AC;&#x201A; |â&#x20AC;&#x201A; July/August 2013

The four most common reasons rosemary plants die when grown indoors are: • lack of sunlight • poor watering practices • powdery mildew • pests If you can avoid these issues, your rosemary plant will live happily inside. Let’s look at how to avoid each.

In the winter, rosemary plants grow much more slowly and need much less water than they do in the summer. Watering too often will cause root rot, which will kill the plant. On the other side, if the soil of the rosemary plant is allowed to dry out completely, the roots will die back and the plant will not have enough roots to support itself.

Powdery mildew Lack of sunlight

Lack of sunshine is the most common reason for a rosemary plant growing indoors to die. Often rosemary plants are brought indoors without any acclimation. They go from six to eight hours of strong, direct light to four to six hours of weak or indirect light. The rosemary plant is unable to produce enough energy to stay alive on this amount of weak light and simply dies. The first step to preventing rosemary light starvation is to put your rosemary on a sunlight diet before you bring it indoors. Several weeks before you bring the rosemary inside, move the plant to gradually shadier areas of your yard. This will force the rosemary plant to grow leaves that are more efficient at turning light into energy, which will help it cope with weaker indoor light when it moves inside. Once your rosemary moves indoors, make sure that you place it in the brightest window in your house, which is normally a south-facing window. If your rosemary plant is not getting at least six to eight hours of light a day, place an indoor lamp as close as possible to the plant to help supplement the sunlight.

Poor watering practices

Indoors or outdoors, rosemary plants are very susceptible to powdery mildew. Most homes do not have the same air circulation as the outside world, which makes this an even worse problem for the plant inside. The best way to drive away powdery mildew on rosemary plants is to increase the air circulation around it. Letting a fan blow on it for a few hours a day or taking it out of more high humidity rooms, like the bathroom or kitchen, will help improve the air circulation. You can also treat the plant with a fungicide to help keep away the powdery mildew.

rosemary moves indoors, make sure that you place it in the brightest window in your house.”

The second most common reason for an indoor rosemary plant to die is poor watering practices. Often, indoor rosemary plants are watered too little or too much. Make sure that the drainage on the container with the rosemary is excellent. Only water the soil when the top is dry to the touch. That being said, never let the soil dry out completely.

Pests

While pests might get the blame for killing a rosemary plant, most pests will only infest a plant that is already weakened. Unfortunately, most rosemary growing indoors, despite all best efforts, grows in a somewhat weakened state. The more strict you are about making sure your rosemary plant is watered properly and gets enough light, the less likely pests will bother the plant. If your rosemary plant is infected with pests, use a houseplant pesticide to remove them. Since rosemary is an herb and it is mainly grown to be eaten, look for organic pesticides. One that is growing in popularity is neem oil, as it is very effective against pests but is completely harmless to humans and pets.

There are few things as troubling as discovering an insect infestation in an otherwise flawless garden. Once discovered, a grower must immediately launch a counter-attack to get rid of those harmful bugs. Here’s a look at one environmentally friendly weapon in the anti-pest arsenal…

Maximum Yield Canada | July/August 2013

Nothing disturbs the production of a flourishing garden or the disposition of a horticulturalist like pests. These nasty buggers can wreak havoc on a plant’s ability to perform while frustrating the gardener into a frenzy of despair. Most gardeners’ first reaction is to buy an insecticide. Don’t get me wrong, there are some great insecticides on the market; however, before you reach for that can of poison, consider recruiting some beneficial insects to do the job for you.

Beneficial insects in nature

“

Horticulturalists who have grown plants both indoors and outdoors notice a difference in terms of pest. Indoor infestations are generally much more destructive and overwhelming than outdoor pest problems. The reason for this is nature’s natural predators. Indoor gardens are safe havens for pests, whereas pests in outdoor gardens are subjected to predatory bugs, birds and other critters that keep their populations in check. Some insect predators are actually drawn to plants by pheromones produced by the pests or the plant itself.

For

every pest, there is at

least one predatory counterpart that can be introduced into a garden in order to naturally battle the bothersome bugs.

Battle of the Bugs Nature is a diverse and powerful force that provides balance in all ecosystems. This balance can be used to a horticulturist’s advantage: for every pest, there is at least one predatory counterpart that can be introduced into a garden in order to naturally battle the bothersome bugs. Here are a couple examples:

Beneficial

insect: Predator mites (Phytoseiulus persimilis, Mesoseiulus longipes and Neoseiulus californicus)

Pest insect: Spider mites Most gardeners would agree that the worst-of-the-worst pest is the spider mite. This is especially true in indoor gardens or greenhouse environments, where entire crops can be wiped out in a matter of days. There are some effective predatory insects that can be used to combat these relentless bugs and the three species of predatory mites (listed above) are the most effective at treating a spider mite problem. Most beneficial-insect suppliers will offer a combination of these three predator mites in one package. This is helpful because they all reproduce in slightly different environmental conditions. In introducing all three predator mites simultaneously, the hope is that at least one of the species will find the garden’s environment suitable for reproduction. Of the three, Mesoseiulus longipes is probably the most suitable for an indoor garden. They have the widest range of preferable humidity and temperature, but, most importantly, they find lower humidities—which are generally found within indoor gardens—suitable for reproduction.

“

a day and adult females will lay up to 15 eggs a day. The total life cycle (from egg to adult) of a spider mite destroyer is around 18 days, with a total lifespan of about eight weeks. When established, spider mite destroyers will reproduce at a rate that is fast enough to destroy a spider mite infestation, hence their appropriate name.

Beneficial

insect: Predator nematodes (Steinernema nematode and Heterorhabditis nematode)

Pest

insect: Thrips or fungus gnats Besides being a huge nuisance, thrips and fungus gnats have something else in common: they both rely on soil or medium for a portion of their life cycle. A great way to treat any pest insect that lives a portion of their life cycle in the medium is to use predatory nematodes. Predatory nematodes are tiny worm-like creatures that feed on the eggs and larvae of soil-borne insects. As soon as any signs of thrips or fungus gnats appear predatory nematodes should be watered in to the medium. Most beneficial insect suppliers sell a combination of both Steinernema and Heterorhabditis nematodes because they work at different depths in the soil. Combined with sticky traps to catch adults, predatory nematodes are an effective and non-toxic option for completely eradicating a thrip or fungus gnat problem.

General predatory

insect: Spider mite destroyers (Stethorus punctipes)

Pest

These tiny beetles are related to the ladybug and feed specifically and exclusively on spider mites. Spider mite destroyers are best used in conjunction with the predator mites due to a long establishment time. These tiny workhorses will eat around 50 spider mites

Beneficial

insect: Whitefly parasites (Encarsia formosa) or Whitefly predators (Delphastus pusillus)

Pest

insect: Whiteflies Whiteflies are one of the easiest pest insects to identify. If you have an abundance of tiny white bugs, you guessed it, they’re whiteflies. Whiteflies themselves do little damage to the plants and are more of an annoyance than anything. When left untreated, however, the honeydew that the whiteflies deposit on the plants will eventually grow a pathogenic black mould that is detrimental to the plants. Whitefly parasites are a grower’s best defense against these annoying buggers.

A whitefly parasite deposits its eggs in developing whitefly pupae. When the egg hatches a whitefly parasite comes out instead of a new generation of whiteflies. This cycle continues until the whiteflies have been eradicated. Whitefly parasites work best on greenhouse whiteflies (the most common variety), but also work well on sweet potato whiteflies and other whitefly varieties. If you have a sweet potato whitefly problem, it could be beneficial to use whitefly predators. These beneficial warriors consume 200 to 800 whitefly eggs per day and prefer the eggs of sweet potato whiteflies (but are generally less effective on greenhouse whiteflies).

Beneficial

insect: Aphid predators (Aphidoletes aphidimyza) or Aphid parasites (Aphidius matricariae)

Pest

insect: Aphids Gardeners with greenhouses or indoor gardens find aphid predators extremely effective against aphid infestations. A single release of aphid predators is usually sufficient to establish a population, but it can be advantageous when experiencing large aphid problems to release aphid predators a few times throughout the plant’s life cycle. Another choice for an aphid problem is aphid parasites, which act as an effective control and preventative measure. Aphid parasites lay their eggs inside living aphids, essentially destroying the aphid internally until they hatch from the remaining insect carcass.

“

General predatory insects

General predatory insects are insects that feed on a variety of pest insects. These opportunist bugs are some of the most common and most effective insects released in gardens for biological control. Below are a few examples:

Beneficial

Pest insect: Thrips, aphids, mealybugs and whiteflies Adult green lacewings feed on nectar and pollen, but their larvae are ferocious predators that feed on a variety of pest insects. Green lacewing larvae are true opportunists and will feed on any insect, larvae or egg that they can inject with their paralyzing venom. These tiny creatures suck the life out of helpless pest insects at an extremely fast rate. Most beneficial insect suppliers will provide green lacewing eggs, which can be distributed evenly throughout the plants. When the eggs hatch, the tiny larvae will search and destroy, traveling up to 30.48 m to find their first meal.

insect: Praying mantis (Tenodera sinensis)

Pest insect: Thrips, aphids, whiteflies, fungus gnat, mealy bugs and spider mites The praying mantis is the ultimate opportunist beneficial insect. These awesome bugs will eat anything they can catch. Praying mantis egg sacks can be hung within the garden’s Maximum Yield Canada | July/August 2013

Battle of the Bugs environment to promote hatching. When the egg sack hatches, over 100 miniature mantises will release their carnage on any and every pest insect they encounter. The tiny warriors will grow into adults over a three to four month period. Mantises are very elusive creatures, so don’t be surprised if you don’t see many after they hatch. A praying mantis will wait patiently, sometimes for hours, until an appetizing insect wanders by. Then, the mantis will pounce on its prey and devour it. Adult mantises are often very territorial and a single adult mantis can claim a fairly large area as its exclusive hunting grounds. Also, mantises feed entirely on other insects making them a great choice for any enclosed garden space.

actually tiny beetles who, like the mantis, feed only on other insects. A ladybug’s favourite snack is aphids, but these opportunists will eat virtually any insect they can fit into their tiny jaws of death. Ladybugs eat thousands of insects in their lifetime (about one year). Another great thing about an established ladybug population is that the larvae are just as carnivorous as the adults. The little larvae resemble tiny alligators and will feed on pest insects’ eggs and larvae. In outdoor gardens, however, ladybugs tend to fly away to their preferred food source, so getting them to establish on the plants can be a little tricky. A sugar water solution can be sprayed on the ladybugs to “stick” their wings together for a few days. This is generally long enough to get them to establish on an outdoor crop. Ladybugs can also be stored at under 10ºC—where they’ll enter a dormant stage—for multiple weeks at a time. This allows a gardener to release 58

”

The implementation of beneficial insects offers a naturalistic approach to solving the ongoing pest insect problems associated with horticulture. There are many advantages to such biological control methods, but the largest advantage is probably the removal of pest insects’ resistance. Any grower who has used chemical insecticides over a period of time only to see the pest become immune will attest to the ongoing anguish of that battle. However, an insect cannot build a resistance to being eaten. By using nature’s solutions, a grower can save their crops from devastation, relieve their frustration and feel good knowing they aren’t contributing to the creation of resistant “super” bugs.

Give Your Ground a Surprise Pop Quiz by Annie Spiegelman

Having your yard landscaped can be expensive; so, before you or someone else starts digging, be sure to take the soil test so your money doesn’t go to waste…

Maximum Yield Canada | July/August 2013

Soil Testing

If you’re thinking about having your yard landscaped, here are some questions to first ask yourself (and anyone else who looks remotely interested) about your backyard soil: • Is the soil worked easily? • Is the soil full of living organisms? • Are earthworms abundant in the soil? • Is water and air available for plant growth? • Does my garden make me look good? “I’m really, really mystified by homeowners who will plop down $30,000 to a landscape designer who will come up with a plant palette without ever thinking to take a spoonful of soil to test it first,” says soil scientist professor Stephen Andrews. “One of the criteria for selecting a landscape architect is to “all home gardeners

caring for a plot of land, large or small, can become superb stewards of their gift from Mother Nature by learning a little soil science.” give them a soil quiz! Ask them what kind of soil test they will be providing. Be an informed consumer.” So, after you’re done hating your compacted soil and admiring yourself in front of the mirror in your new garden hat, it’s time to get scientific. Why?

Because we compost spinning tree huggers believe all home gardeners caring for a plot of land, large or small, can become superb stewards of their gift from Mother Nature by learning a little soil science. “If you’re going to do any type of landscaping project, make sure to test your soil first to understand what kind of a baseline you have,” says Andrews. “If you’re changing a large backyard area, doing drainage work or you’ve just purchased a new home, go get a commercial soil test done. It might cost you a few hundred dollars, but you’ll have a thorough analysis and interpretation of your land. The soil scientists at the testing company will give you specific advice on how to proceed.” For the rest of us, who don’t have the green to spend on the brown, it’s perfectly fine to take the mom-and-pop route. Head down to your local plant nursery and purchase a home garden test kit. A good soil test will run about $20. Do it with the kids or grandkids. Or, get the entire neighbourhood and have a soil testing barbecue! One test kit will have enough tubes to do 10 soil tests. You might be the diva who does everything organic, but…you’re living next to Charlie Chevron who uses every petrochemical on the planet. Get together and literally talk dirt.

"When collecting

your home soil sample, choose a few different sections of your yard.”

Maximum Yield Canada | July/August 2013

With the home soil test, you’ll be testing your soil’s pH. The pH level will tell you if nutrients are actually available to your plants or if you’re just out fertilizing, polluting and wasting your hard-earned cash on garden products. “The ideal pH of soil for many common plants is 6.5. The reason we want the soil to be slighty acidic is because the plant nutrients are carried in a solution. If it’s slightly acidic, the nutrients can dissolve and can be transported,” says Andrews. “If the pH is too alkaline, the nutrients will sit there like lead balls of pasta, not going anywhere. By having it slightly acidic you have the best pH for nutrient uptake. To lower the pH, use coffee grounds, tea bags, sulphur, aged animal manure or compost. To raise the pH, add limestone or oyster or egg shells.” Home tests also check the availability of your soil’s macronutrients: nitrogen (N), phosphorus (P) and potassium (K). These are the main nutrients and minerals needed by your plants (which is why you’ll see the letters N-P-K on fertilizer containers). Once you know which nutrients are already hanging out in your soil, you won’t be wasting money on unnecessary products. When collecting your home soil sample, choose a few different sections of your yard. For instance, your edible garden in raised beds would be one test area, while your front lawn, a slope or a woody spot would each be a separate area to test. “For each chosen area,

do a representative sampling. Pick 10 to 15 different spots in that area and dig down 15 to 20 cm,” recommends Andrews. “Remove critters, rocks, roots and plant material. You just want soil parts. Take all samples from that area and mix them into a plastic baggie. Label the bag and the area accordingly. For a lawn, dig down only 5 to 8 cm.”

“Testing your soil twice a year—once in the spring and again in the fall—is especially helpful if you’re growing fruits and vegetables year-round.” If you’ve decided to do the commercial test, you’ll want to decide just how comprehensive a test you need. Andrews suggests testing for pH nutrient availability, particle size analysis, bulk density, moisture content, organic matter content, macro- and micronutrients and soluble salts. If you live in an urban area and are growing edibles, or in an older home where lead contamination from paint is prevalent, heavy metals testing should be done as well. As mentioned earlier, commercial soil testing should be done when you first move into a home. It should also be done every 10 years or so, depending on your budget and your gardening success or utter failure. The home soil test, on the other hand, would be useful to do any time a considerable amount of plants in your yard look beaten down, chewed up or super sluggish. (Gardeners don’t have patience for lollygagging plants. Testing your soil twice a year—once in the spring and again in the fall—is especially helpful if you’re growing fruits and vegetables year-round. “Cold season crops have different needs than warm season crops. Like us, our underground soil friends slow down when it’s colder outside,” says Andrews. “The bacteria slow down; but, once the soil warms up, the disco lights come on and they’re ready to party!”

When asked to divulge something that might surprise readers about the company, Linda shares, “I think our customers and readers are often surprised to learn that we have our office on Vancouver Island in British Columbia in a small town (population of 94,000) and that we create all of our international publications at this location, from advertisement sales to graphic layout, editorial and even the direct-to-plate production. We welcome everyone to stop by and say hello any time they are in Nanaimo. We love visitors!” And, if you do find the opportunity to stop by the office, what you can expect to see in the day-to-day operations of the magazine is a lot of hustle and bustle! “Life in the Maximum Yield office is busy, day in and day out, as we help customers around the world connect. We begin our day contacting clients in the United Kingdom and Europe, followed by our North American clients and wrap up our day with calls to our Australian and New Zealand clients. From helping retail shops to creating marketing campaigns for our manufacturers and distributors, to booking booths at an upcoming Indoor Gardening Expo, our days are never boring and always extremely rewarding,” adds Linda. Not foregoing its own achievements, Maximum Yield has also helped many young companies grow into international success stories over the years. Surely, there must be a secret to this. “There is no secret, just our desire and determination to help companies succeed. We help by introducing the products to retail shops globally through our Industry News, and then help them build a marketing campaign in Maximum Yield and Hydrolife based on their budget and goals. Maximum Yield offers a multifaceted platform to promote your company, from our publications and web, to social media

The look of Maximum Yield may have changed over the past 15 years, but the magazine’s goal has remained the same: to educate and promote sustainable indoor gardening to the masses, and to help companies promote and grow their business globally.

and the trade shows. Combined, they offer the strongest media to reach and grow your business globally,” says Linda. “We feel successful when our customers have grown their business through their investment in our media properties. We have been told many times over how Maximum Yield has been instrumental in our customers’ business growth. When this happens, we know we’re doing the right thing,” says Jim. Linda adds that the best advice she would give companies and entrepreneurs just starting off in the industry would be to pick up the phone and call Maximum Yield. Its trained marketing representatives can help connect and promote businesses in a way that meets each company’s individual needs and goals. The dynamic team at Maximum Yield is comprised of owners Jim and Linda Jesson and Don Moores; sales manager Ilona Hawser; sales team Kelsey Hepples, Katie Montague and Jed Walker; graphic manager Alice Joe; graphic designers Jennifer Everts, Dionne Hurd and

Jesslyn Gosling; assistant editor Julie McManus and accountant Tracy Greeno. “Each and every publication produced is a team effort, and the hard work and dedication necessary to make it happen is constantly celebrated. The dedicated team and strong vision in the Maximum Yield office has a tremendous impact on the continual growth and advancements with the company,” says Don. When asked what’s in store for Maximum Yield in its next 15 years, Linda shares, “Maximum Yield will continue to strive to educate and promote sustainable gardening to the masses and to help companies promote and grow their business globally. I believe the world is smaller because of our ability to connect businesses through our publications and trade shows worldwide. We will continue to grow and expand our social media presence along with developing more web and video education. The thought of having a hydroponics system in every household would be a dream come true! Let’s make that happen in the next 15 years!”

“Each and every publication produced is a team effort, and the hard work and dedication necessary to make it happen is constantly celebrated.”

Here’s what our clients are saying Congratulations Maximum Yield! Fifteen years strong! Maximum Yield has been a staple magazine in the Can-Filters office for years. It’s great to see all the new ads that companies are coming out with, and it’s the first place to look to check out if anyone is coming out with new products. Reading through the articles really helps expand my knowledge in subjects I didn’t know much about before. And whenever I am planning a trip through any given area, I’m sure to cross reference my trip list with the store locator at the back of every issue. Let’s not forget the trade shows. Max Yield has always shown us a great time and I look forward to the shows that I am able to attend. The networking and face-to-face meetings are priceless and the friendships built will last a lifetime. Thank you so much for what you’ve done for the industry and I can’t wait to see everyone again soon! Brandon Arcuri, Outside sales Can-Filters

We’d like to thank Maximum Yield for all of the great exposure they have helped give us over the years. We have really benefited from doing business with them and wish to congratulate them on their 15th anniversary. Melissa Lehmann, Sales representative Atmosphere

Congratulations on your many years serving our industry! You are all such outgoing and fun people, and you have done a wonderful job getting everyone together for your many shows! All the best from the staff at Nutrilife Plant Products

For the past 15 years, Maximum Yield and Future Harvest Development have formed a close working relationship. Perhaps this is because both companies are from British Columbia, but we think it’s mostly because of the great service and passion for indoor gardening that both companies share. Maximum Yield magazine has come a long way over the past 15 years and has become the number one source for information on how to grow and source innovative new products. We recall one of the first ads we put in Maximum Yield for SunBlaster Lighting in 2002. Thanks to these ads in Maximum Yield magazine and the fantastic trade show opportunities, we have been able to reach the customers and strategic partners that have allowed us to become one of the leading manufacturers of indoor growing equipment, showcasing brands such as SunBlaster Lighting, PlantLife Products and Nutradip. A big thank-you to Maximum Yield from all of us for providing unprecedented service over the past 15 years. Congratulations on your 15th anniversary; we look forward to working closely over the next 15 years. Kirk Glendening, Customer support representative Future Harvest Development

It is with great pleasure that Eddi’s Wholesale Garden Supplies sends our congratulations to Linda and Jim Jesson and the Maximum Yield team on 15 outstanding years in our industry. It seems like only yesterday you started Maximum Yield. From a small beginning, you have now gone on to unite the whole hydroponic market. Your spirit, drive and hard work have made your organization what it is today. This anniversary is a milestone to celebrate. Congratulations! Andi Wilson and the Eddi’s team Eddi’s Wholesale Garden Supplies, Ltd.

First off, both Excel Air Systems and myself would like to congratulate Maximum Yield on this very special anniversary! Being a supporter from the early years, I’ve had the pleasure in watching the publication grow exponentially from a single magazine in Canada to an industry-leading multi-country publication with one of the top trade show circuits in North America. A large part of our growth at Excel Air Systems has come directly from our exposure in Maximum Yield magazines, but even more so at the tradeshows, where the quality of retail shops and customers that attend these shows makes it a great opportunity to talk face to face and connect on a direct level. The biggest reason Excel Air Systems has been a Maximum Yield partner for so many years is because they believe in providing great knowledge to their customers and have built a tremendous foundation to withstand the test of time. I can’t wait to see what the next 15 years looks like. Keep up the good work! Brandon Kion, Excel Air Systems

Congrats to Maximum Yield for always being the premier source of information for the indoor gardening industry! We at Commercial Lighting Products have made it our go-to magazine for product information and advertising exposure since we’ve been in the industry. Here’s to another great 15 years! Tayhler Paul, Marketing and communications associate Commercial Lighting Products

As one of the first publications dedicated to hobby hydroponics, Maximum Yield has been a big part of getting our industry off the ground. We are so proud of what Maximum Yield has accomplished and how they have connected industry leaders, consumers and newcomers to the field of progressive gardening. With the help of this publication, our industry has grown in leaps and bounds and is now one of the fastest growing sectors in North America. Thanks, Maximum Yield, for bringing us out of the shadows and lighting up our lives. With love, Alex Rea and the whole Homegrown Hydroponics team Maximum Yield Canada | July/August 2013

DO YOU KNOW?

Spider mite destroyers (Stethorus punctipes) are tiny workhorses that will eat around 50 spider mites a day. Adult females will lay up to 15 eggs a day.

Glassiness is a physiological disorder in plants related to humidity levels, most commonly seen in lettuce, young seedlings and other succulent crops. Glassiness creates patches with a water-soaked, almost translucent, appearance on the leaves of plants, and is related to both high humidity and root pressure.

Overly vegetative plants don’t have many developing flowers or fruit, as they are sending most of the assimilate produced via photosynthesis into further leaf growth.

Aloe vera has been used medicinally for 6,000 years. In both the 18th and 19th centuries, it was among the most frequently used prescriptions.

Carbon, sediment or reverse osmosis purification systems can help provide a high-quality water source for all plants in your garden.

Enriching an enclosed growing area with CO2 can result in significant growth benefits; however, CO2 toxicity can occur when levels run too high.

Commercial soil testing should be done whenever you move into a new home.

The ideal pH of soil for many common plants is 6.5. The reason we want the soil to be slightly acidic is because the plant nutrients are carried in a solution. If it’s slightly acidic, the nutrients can dissolve and can be transported.

If possible, always start seeds inside under grow lights so the weeks of early vegetative growth are already done when the time for outdoor planting comes.

Bolting is the term used to describe the premature elongation of a plant’s compact stem. Typically, this occurs when temperatures are higher than optimal, often combined with low light levels or overcrowding.

Building Blocks of Growing Fire, water, earth and soil used to be the building blocks of the world. While atoms and string theory have taken over their places in science, there’s no denying that the four elements still play a critical role in growing healthy plants.

Improving Flavour When it comes to good food, we are all looking for taste, aroma and texture. Sometimes these all come together to create a sensory delight, but when it comes to fruit, vegetables and herbs, appearances can be deceiving.

Organic Bloom Boosters To get the most out of their plants, gardeners use nutrient additives, soil amendments and foliar treatments specifically designed for particular stages in a plant’s life cycle. There are plenty of choices available, including some high-performance organic options.

PLUS: Hydroponic news, tips and trivia, hot new products, exclusive giveaways and more!
