A high-quality Trichoderma harzianum inoculant for professional growers and home gardeners. Improves plant health, soil biology, and long-term sustainability in organic systems.
A small vacuum-sealed vial containing 6.6 g of pure Trichoderma harzianum spores at a concentration of 3.2 × 10¹⁰ CFU/g — roughly 210 billion viable spores per vial. Sealed vials keep for around 2 years.
No special equipment needed. Just open the vial and mix with water as below.
This is a living inoculant, not a fertiliser — getting the dose slightly off won't burn or starve anything the way over- or under-feeding does. Once the spores establish, they multiply based on available food (root exudates, organic matter, competing fungi) and revert back to spores when the food runs out. For Trichoderma harzianum, that cycle is roughly 6 weeks. The soil decides how dense the population gets, not the label.
Standard mix: one full 6.6 g vial into 100 L of water. Shake until dissolved.
Smaller batch: about 0.33 g per 5 L of water (roughly a small pinch — exact weight isn't critical).
Apply as a foliar spray or soil drench. Use the mixed solution within 24 hours — once it's in water the spores begin activating and shelf life drops sharply.
Trichoderma harzianum produces over 250 metabolic products including cell-wall-degrading enzymes, peptides, secondary metabolites and other proteins. Many of these are bioactive and shape how the plant responds to other microbes — improving plant defences while stimulating root growth and development.
