TrikoLogic® vital for organic growing High quality dry Trichoderma harzianum culture. Vital for Organic growing, and every commercial gardener’s secret weapon. Trichoderma breaks down organic matter in substrates releasing the minerals that plants feed on. This process of decomposition and nutrient release is fundamental to organic and bioponic gardening. On top of this benefit, as it establishes colonies, Trichoderma 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 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.
