About this episode

Dr. Russell Sharp discusses how to select and utilize microbial biostimulants in hydroponics.

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. https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/ Ben Lugtenberg — Leiden University Jos M.
