Use Organa-Guano as a flower catalyst in your horticultural system. This liquid formula of all natural bat guano is derived from fruit eating bats and contains the highest rate of phosphorus without added synthetics. Organa-Guano's completely solubilized liquid solution is also three times more cost effective then a concentrated powder formula. Phosphorus is more easily absorbed, will stimulate early flowering, contains beneficial enzymes, and will increase number of branches/flower sites, enhance aroma and improve taste. The formula is non burning and contains no odor or harmful residue. Organa-Guano is great for hobbyists and professionals alike! Quantity: 1 Gallon.
