Mykos (mycorrhizae) is a highly-beneficial soil fungus which, once applied to plant roots, lives for the life of that particular plant. When Mykos fungi colonize a "host" plant's root system, it spreads out thin fungal filaments called "hyphae" from the root surface into the surrounding soil. These hyphae spread out far beyond the reach of the root hairs and access vastly-larger amounts of soil (up to a thousand times more), retrieving otherwise inaccessible stockpiles of nutrients and water. This nutrient "super-mining" effect, is one reason why a partnership between Mykos and plants so highly-beneficial. Mykos greatly increases plants' ability to absorb and compete for precious soil nutrients.
