Hydroguard’s unique formula, available exclusively from Botanicare, contains an isolated form of Bacillus bacteria known as Bacillus Amyloliquefaciens. This scientifically isolated bacterium was selected 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. Bacillus Amyloliquefaciens has proven to be especially effective at inhibiting the formation and spread of water-borne pathogens (i.e. Pythium, Fusarium, Botrytis, and Phytophthora). Upon application, the highly concentrated and pure culture of Bacillus bacteria in Hydroguard rapidly colonize the root zone and form a network of highly efficient microbes that work together to deliver exactly what each plant needs when it’s most crucial. These specialized rhizobacteria activate the plant’s natural defense system, assist in the breakdown of organic materials, and increase nutrient availability.
