Rhizo Charge 2.0 is a high performance mycorrhizae food, meant to be used on transplant day. Rhizo Charge is comprised of a complex blend of microorganisms, humic material, and complex carbohydrates to help feed your soil and feed your plant a biologic soil enhancer, localized right at the root zone. Rhizo Charge is a food that we recommend to use with the "Green 150" or the "Hydro 110", depending on your project. After you dust your roots with the "Green 150' (or the "Hydro 110"), it is ideal to feed your roots, packing a second punch will help with more aggressive colonization of the mycorrhizae. Rhizo Charge can be used multiple ways; can be used as a food for the mycorrhizae in the transplant hole or use it to top dress/mix it in with loose soil.
