Tribus Microbes Grow

  • $57.95

An advanced bacterial inoculant for use in high-performance cultivation systems during vegetative growth. 

Plant's needs change. So should your inoculants.

Manipulating the type and concentrations of beneficial bacteria specifically for vegetative growth helps support abundant root growth and aggressive plant development. Tribus® Grow is a proprietary formula of growth-promoting rhizobacteria that work together to improve nitrogen uptake and mobilize micronutrients, optimizing plant size and structure during vegetative growth.   

Tribus® Grow optimizes high-performance cultivation systems by protecting the plant from high salt stress, allowing growers to worry less about nutrient burns and salt buildup when pushing plants hard. 


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 can 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
  • can aid in iron and micronutrient uptake
  • low-foaming and low-biofilm formulation makes hydroponic use practical 
  • in soil/potting media, these bacteria can survive for years (even during drought!)
  • One year minimum guaranteed shelf life
