Hydroguard® is back with a new, clean look and a more powerful, concentrated formula. 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.
