Here you can purchase Tribus Microbes easily in USA- Impello Biosciences
Tribus Microbes Original is a liquid biostimulant that contains three naturally occurring rhizobacteria (Bacillus subtilis, Bacillus pumilus, and Bacillus amyloliquefaciens) that rapidly colonise the root zone of plants. These bacteria produce extracellular enzymes and other biochemicals in order to work in a symbiotic relationship with plants. This beneficial relationship helps the plant grow bigger, stronger, and faster by increasing nutrient uptake, rooting speed, and root and stem growth.
