B.C. Hydroponic Nutrients are a power-packed trio for nurturing generous vegetative crops and extraordinary floral growth. B.C. Boost, B.C. Bloom, and B.C. Grow are complete, professionally formulated, highly concentrated fertilizing agents. Unlike other brands, which include micronutrients in only one part of the formula, both B.C. Grow and B.C. Bloom contain a full complement of micronutrients, which are bolstered by the added calcium and iron in B.C. Boost.
