High quality dry Trichoderma harzianum culture

A vital part of Organic growing, and every commercial gardener’s secret weapon

BM® is our brand of Trichoderma harzianum: the first beneficial microbial inoculant to become standard in the commercial greenhouse industry.

Trichoderma lives in soil, coco or other similar substrates breaking down organic matter and releasing minerals. This  process  of  decomposition  and  nutrient  release  is fundamental to Organic, Organic Hydroponic, and Bioponic gardening. As it grows and establishes colonies, Trichoderma also releases a range of plant growth stimulating compounds and substances that inhibit or kill pathogens in the soil which might otherwise harm your plants - as the latest research has been demonstrating.

It’s this range of benefits, for young plants in particular, that has led to Trichoderma becoming a standard in the industry.

As with all GHE products, our Trichoderma brand is of the highest quality - all strains and cultures are not equal, and some are significantly less viable than others. We are proud to say that our beneficial microorganism products, bacteria and fungi, are amongst the highest quality on the market.

BM meets European regulation 2008/113/CE on organic agriculture.
It is registered under: BBA Nr LS 004987-65-00

How to use BM:

As with all aerobic microorganisms, the better the oxygen supply, and the more stable pH, temperature and humidity are; the healthier and more effective BM® will be.

  • As a drench when sowing seeds, and as an additive to water/nutrient for seedlings, young, and adult plants: add 1g for every 15 to 20 litres of water or nutrient solution every 6 to 8 weeks.
  • For adult plants, in soil or coco: add 10g for every 150 to 200 litres of water or nutrient solution every 6 to 8 weeks; just add to your water/nutrient system, or water directly onto substrate.
  • In pure, bare root hydroponics and bioponics: When plants are young and have small root systems, BM® needs a base to regroup and reproduce: to provide this use a commercially available biofilter unit, or suspend a 3 to 5L plastic basket filled with 80% clay pebbles and  20% coco coir under falling water in your tank, e.g. under the return of our Aeroflo® systems. 

Use BM with:

  • All GHE nutrients and substrates, in hydroponics and outdoor gardening.
  • General Organics Thrive® and other organic nutrients work particularly well with GHE BM®
