Our special, micro-brewed formula incorporates earthworm castings, bat guano and other high test organic ingredients that offer a full, balanced range of nutrients. Norwegian kelp improves nutrient uptake and increases yields. Rock phosphate helps transfer energy from one part of the plant to another, which means bigger buds and more fragrant flowers.
