Mykos - Pure, Fresh & Alive: A beneficial organism, Mycorrhiza, plural Mycorrhizae, lives on the roots of plants and forms a symbiotic relationship. It then extends microscopic straw-like filaments called "hyphae" into the soil with which it extracts, transports, and dramatically increases a host plant's supply of nutrients and moisture. Pockets of nutrients and water in the soil which were once unreachable by standard root systems are now made accessible through the "super-mining" effects which mycorrhiza gifts to your plants.
