Plant Magic Granules are mixture of mycorrhizal fungi and 20 strains of beneficial bacteria which are held dormant in a granular form. When the granules are added to a soil or coco mix and watered, the organisms wake up and begin to do their work. The mycorrhizal fungi work symbiotically with plant-roots, creating a network within the soil which vastly increases the effective root-mass of your plant. The 20 different strains of beneficial bacteria do various different jobs from fixing nitrogen into the soil to helping fight off root-diseases. All in all, Plant Magic Granules greatly increases the bio-activity in the soil, reliably producing healthier and better yielding plants.
