2.5-4-3 GroBetter is derived from fully composted pure chicken manure to feed plants with slow-releasing nutrients while enriching the soil with organic matter. Grobetter is pelletized for quick and easy application, does not contain any fillers, has low-odor and is non-burning. Replace all those heavy, smelly bags of chicken manure with Grobetter as five pounds of Grobetter is equal to five to seven bags of chicken manure. Use at a rate of 5 lbs per 160 square feet or, for containers, half a teaspoon per inch of pot diameter. Organic Materials Reviews Institute (OMRI) listed.
