Don't Get Ripped Off: How to Choose Microbial Biostimulants

Dr. Russell Sharp explains how to choose and use microbial biostimulants for hydroponics, focusing on production/expiry dates, manufacturer credibility, and the trade-offs between liquid and powder formulations.

He recommends trusted suppliers (Legume Technology, Omex/Biomex, Symbiom, Koppert's Trianum P), suggests starting with Bacillus blends and Trichoderma, and advises using seaweed extracts, humic acids and mild fertilizers to feed, not kill, microbes.
