Impello Biosciences Tribus Original® is a highly concentrated microbial inoculant featuring a synergistic consortium of three elite rhizobacteria, Bacillus subtilis, Bacillus amyloliquefaciens and Bacillus pumilus, at 10 billion CFU per mL. These endospore-forming Bacillus strains quickly colonise the rhizosphere, producing extracellular enzymes and siderophores that mobilise, solubilise, and chelate nutrients for enhanced uptake. The result is faster root initiation and expansion, more efficient water use, accelerated vegetative growth, and improved yield quality from seedling to harvest.
Independent trials have shown measurable gains, including +15% increase in dry weight yield, +14% increase in growth rate, and +16% increase in stem diameter.
Engineered for reliability, Tribus Original integrates cleanly into any nutrient program and delivery method (soil, coco, hydroponics, DWC, drip), without foaming, gunk, or biofilm. The pH- and salt-tolerant formulation remains stable in solution (use within 24 hours for best results) and is backed by a minimum 18‑month shelf life when stored correctly.
Unlock nutrients, build roots, and accelerate growth from seedling to harvest.
