"I use a few multi-microbe products, and they all contain a few bacillus, but none have ever made my roots do that over night. The most noticeable and intense results from a single product I've ever used."

"With other microbial products, I wasn't sure if they were helæing at all. Tribus changed all that when I observed plant growth like never before. I'll never grow without it."
