The word mycorrhiza, of Greek origin, defines the symbiosis between a fungus and the roots of a plant. As in many symbiotic relationships, both participants gain benefits. In this relationship, the fungus feeds on sugars (such as carbohydrates) produced by the plants through photosynthesis and, in return, the fungus makes water and nutrients more available in the soil for them. There are two types, each of which works somewhat differently but results in the same benefits which are, improved nutrient uptake, improved drought resistance, protecting plants from harmful pathogens and improving soil structure and retaining carbon.
Ecto mycorrhizal fungi are those fungi that form a beneficial relationship but live in the rhizosphere, these organisms live just outside the root system protecting plants from disease.
Endo mycorrhiza live inside the roots, they help in the absorption of nutrients and water in exchange for sugars which brings many benefits to all plants, including cannabis.
It uses beneficial fungi to help roots develop and improve plant growth.
