MYKOS® mycorrhizae is a natural and organic species of beneficial soil fungi that create a "sponge-like" mass which collects and stores nutrients and water, increasing the uptake of both. StrengthsMYKOS is a beneficial soil microbe that enhances root structures by forming a symbiotic relationship with a host plant. Acting as an extension of the roots, Mykos increases the plant's ability to source nutrients and water more efficiently in exchange for carbohydrates. Can also increase crop yields & secondary metabolites. UsesApply around the root zone of plants. Apply weekly through vegetative and early flower stages.
