MegaPhos is a high concentration of a unique, natural, wild microorganism named Bacillus megaterium strain HM87. This potent microorganism is essential for phosphorus uptake in plants, especially when bound in high pH soils.
When applied to the plant, MegaPhos grows on the root system, colonizing and taking up residence in the rhizosphere. While there, MegaPhos produces several essential enzymes and secondary metabolites that helps solubilize bound or tied up phosphorus, making it more available to the plant.
Use 1/16-1/4 tsp per gallon. Reapply each time nutrient solution is changed.
