Do more with less. Hydroguard is back. Our new formula is more concentrated, more powerful and more effective than before. Hydroguard's unique formula, available exclusively from Botanicare, contains an isolated form of Bacillus bacteria known as Bacillus Amyloliquefaciens. This bacterium was selected, specifically, for it's superior ability to amplify root mass and health, especially in hydroponic gardening, when compared with the more common and well known Bacillus Subtilis species. Upon application, the highly concentrated and pure culture of Bacillus bacteria contained in Hydroguard rapidly colonize the rhizosphere. These specialized rhizobacteria, assist in the breakdown of organic materials and increase nutrient availability. From seedling to harvest, optimizing the size and health of your roots is the first step towards maximizing your plant's yield.
