Transplanting & Housing Starter Plants Plants grown utilizing the high-performance method will be transplanted twice in their lifetime. The first time is when they are small seedlings or rooted clones, and then again when they are placed into their final homes outdoors once the conditions are appropriate. Trans- planting will be done the same way for both seedlings and rooted clones. The key to a high-performance outdoor cannabis garden is in the rapid development of an extensive root system. An expansive root system leads to an increased ability to absorb larger amounts of water and nutrients. The more nutrients a plant can access the bigger it can grow. For that reason every container used should be a fabric aeration container. The initial transplant from the seedling/clone stage should be into a five- to 15-gallon container. A five-gal- lon container is the absolute smallest a grower should use. Fill the containers with a soil-less potting mix that has a low-to-moderate nutrient charge, but is similar to what will be used in the final outdoor containers. A mix that is mostly comprised of inert materials, such as peat moss, perlite, or vermiculite, will have a lower nutrient charge when compared to mixes that contain organ- ic materials like earthworm castings, kelp meal, or composts to name a few. The soil-less potting mix can be pre-moistened if desired to create a uniform distribu- tion of water. When transplanting, it is important to not overwater as doing so will slow down the initial root growth, lengthening the amount of time it takes for the plant to recover from the transplant stress and to assim- ilate to the new container. High-performance outdoor cannabis gardens thrive when growth and development is not interrupted, even for a short time. To help reduce the stress of being transplanted to a new container the seedlings or clones should be treated with beneficial microorganisms or microbes. The two main microbes that will help the plant recover quickly are the nitrogen-fixing bacteria Azospirillum brasilense and the Arbuscular Mycorrhizae fungi Glomus intaradices. Azospirillum breasilense is a beneficial bacteria that attaches to a growing root, forming small nodules and that helps convert nitrogen from the atmosphere into plant available forms. Mycorrhizae fungi, on the other hand, have the ability to locate and obtain nutrients in the soil mix that may be less available to the roots. The nutrients can become unavailable to the roots for many reasons. They may be in a portion of the growing media that the roots have not or cannot access for some reason, or they might have become attached or bonded at the ionic level to an opposite charged soil particle, which is often the case for positively charged phosphorus ions. Mycor- rhizae fungi will grow on, as well as within, a plant’s roots. It is from that point where they will venture into the rooting medium and create a vast net-like structure 48 • Professional Marijuana Grower November/December 2018
