by Andrew Schell Scientists are learning more and more about mycorrhizae, the symbiotic associations between fungi and plant roots, and the benefits these relationships can have on plants. Here’s everything you need to know about incorporating this age-old partnership into your gardening practices.154 Maximum Yield USA  |  July 2015



MYCORRHIZAEUNDERSTANDING EC, TDS & PPM “We know more about the movement of celestial bodies than about the soil underfoot.” —Leonardo da Vinci Scientists and farmers have uprooted an ancient partnership between plants and fungi. This mutualistic association, called mycorrhizae, has been around for more than 400 million years—basically as soon as plants found their way onto land. More than 90% of plant families form these symbiotic relationships at the root level with fungi. This sustainable partnership is essential to the circle of life. Plants supply fungi with energy in the form of carbohydrates that are produced during photosynthesis. Fungi are unable to produce their own food from the sun as they lack pho- tosynthetic pigments such as chlorophyll. In return, fungi increase the survival and growth rates of plants by expanding the surface area of roots so more water and nutrients can be absorbed. The fungal network can transport water and nutri- ents over large distances and deliver them to the vascular tissues of plants. Roots with this network display an increased uptake of typically insoluble compounds, particularly phosphorus. The fungi also modify amino acids and carbohydrates for storage, or transfer them to where they are needed, and help plants cope with many environmental issues such as high salinity, drought and pH fluctuations. Mycorrhizal fungi help plants combat harmful pathogens, including the fungus-like genus pythium that causes root rot, by manufacturing and releasing particular enzymes and antibiotics as plants require them. Individual plants are connected with other plants through this mycorrhizal network, and can even share nutrients, sugars and water. The fungal network is embedded in the vegetative fungal tissues known as mycelium. Multiple species of fungi and plants can be connected through the mycelial network. This enriches the local community and also extends to interactions with earthworms, bacteria, nematodes and other organisms. Plants supply fungi with energy in “ the form of carbohydrates that are ”produced during photosynthesis.156 Maximum Yield USA  |  July 2015

One common myth in the indoor gardening industry is that mycorrhizal fungi do not have an application in hydroponics. The truth is that endomycorrhizal fungi do not require soil media to inoculate a plant’s roots. The fungal associations thrive in hydroponic systems as well as the roots of aquatic plants. It is important to supply high-grade carbohydrates to your nutri- ent regimen if you are using mycorrhizal fungi, as the fungi require carbohydrates for energy and they obtain them from the plant if there is not a sufficientZAEamount in your feed water. Feed the fungus, or it will take valuable energy from your crop. Endomycorrhizal fungi also help with the remedia- tion of depleted soils like the peat-based and recycled mixes now common in the indoor gardening industry. Harnessing the power of mycorrhizal fungi in the garden is a key step in moving forward from the out- dated paradigm of global agriculture. Force-feeding our crops with industrial nutrients, herbicides and pesticides is not only unhealthy and unsustainable, it is unnecessary.

Like all hanging planters, they dry out rapidly in sunny weather, so your plants will require even more constant watering than they would in standard pots. Also, the soil in a hanging container heats up quickly, causing stress. Gardeners using light-colored, 5-gal. plastic buckets report having some luck. For the best chance of success with this method, choose only small- fruited varieties and start out with big, tall, vigorous seedlings so they can be planted deeply (that is, with roots very close to the top).

TIPS & TRICKS Simplified.CO2 Supplementation, By Garrett Cropsey One of the easiest ways to provide indoor plants with extra CO2 is by using mycelial CO2—a byproduct of growing fungi in your garden. Maximize your efforts using this method of supplementation with these tips. Plants grown indoors often consume more carbon dioxide than what enters the grow space naturally. These same plants become more productive when CO2 levels are maintained at higher levels than atmospheric concentrations. For these reasons, indoor gardeners provide supplemental CO2 to their growrooms using a variety of methods. Compressed tanks, burners and the gardener’s own breath are all effective at providing extra carbon dioxide, but mycelial CO2 production is the easiest and most cost-effective means of maintaining beneficial levels in gardens up to a certain size.164 Maximum Yield USA  |  July 2015
