Great White Granular 4

Great White Granular 4 by Plant Success (Plant Revolution) is a single-species mycorrhizal inoculant in a dry granular format, designed for direct application to the root zone during planting or transplanting. Unlike the premium Great White powder which contains multiple beneficial species, Granular 4 uses a single targeted mycorrhizal strain — making it the most affordable entry point into mycorrhizal inoculation in the Great White lineup.

Mycorrhizal fungi colonize plant roots and form a symbiotic network that dramatically extends the effective root surface area. This improves water uptake, phosphorus absorption, and overall nutrient efficiency throughout the grow cycle. Established colonies also protect roots from certain pathogens and improve drought resilience.

Apply granules directly to the root zone at planting — placing inoculant as close to roots as possible gives the fastest colonization rates. Works in soil and coco; not recommended for hydroponic systems where no solid media is present for fungal attachment. A cost-effective way to establish beneficial mycorrhizal populations from day one, particularly useful for growers starting from seed or transplanting clones.
