Mycorrhiza is the name given to specialized forms of fungi that grow on plants' roots and spread deep within the soil. The fungal filaments within the soil are an extension of the root system and are far more effective at absorbing water and nutrients than the actual roots.
The term Mycorrhizal refers to the relationship that exists between beneficial fungi and the roots of plants. This colonization is an extension of the root system and extends well into the soil, growing in association with most plants.
The science behind beneficial microbes is very complicated. Still, the fundamental reality is that beneficial microbes for hydroponics provide growers with a wide array of benefits that cannot be matched.
Bacteria often have a terrible name, but many bacteria strains are very beneficial, both to human beings and other life forms. Bacteria are the smallest life forms on the planet, as well as one of the most abundant and oldest, and soil fungi helped shape the soil structure of Earth and set the stage for plant life to evolve.
