Impello Bio Tribus Grow

Bacterial Biostimulant Designed For Vegetative Growth


Ideal for use in high-intensity cultivation systems

Bacterial communities on plant roots change as plants transition from vegetative growth to flower, so we designed Tribus Grow™ & Tribus Bloom™ inoculants to reflect this change. 

Tribus Grow is a blend of plant growth-promoting rhizobacteria (PGPR) specifically designed to optimize vegetative growth by populating the rootzone with beneficial bacteria that fix, mobilize, and chelate nutrients necessary for healthy vegetative growth.

In addition to the added Brevibacillus and B. licheniformis species, which decrease the chance of nutrient burn and increase enzyme production, this blend utilizes the same powerful bacteria that are in our other blends, but in concentrations that better suit the plant's needs from seed germination through the flowering transition period. 

While this formulation has been optimized for vegetative growth, it retains all of the growth-promoting characteristics of our original Tribus Original™ formula:

  • Produce enzymes and other biochemicals that mobilize nutrients and aid in nutrient uptake

  • Aid in iron and micronutrient uptake

  • Low-foaming formulation makes hydroponic use practical

  • In soil/potting media, these bacteria can survive for years (even during drought!)

  • Minimum 18 month guaranteed shelf life
