Big Bloom Liquid Plant Food (0.01-0.3-0.7) is a 100 percent organic fertilizer that promotes multiple blooms while dramatically enhancing the flavor of fruits and vegetables. Also great as a tonic and transplant fertilizer, Big Bloom incorporates earthworm castings, bat guano and other high test organic ingredients that offer a full 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 flowers that are more fragrant. For optimal results, Big Bloom is recommended for every stage of growth in conjunction with Grow Big and Tiger Bloom and can be used in both hydroponic and soil applications.
