Probiotics
W2G Probiotics is a highly concentrated microbial inoculant designed to enrich the root zone with beneficial fungi and bacteria. Formulated with 16 species of endo- and ecto-mycorrhizal fungi, 8 species of Trichoderma, and 57 species of beneficial bacteria, it provides over 1.4 billion colony-forming units (CFU) per gram. This powerful diversity enhances nutrient cycling, root colonisation, and overall plant health.
Suitable for seedlings, cuttings, and mature plants, W2G Probiotics actively suppresses harmful anaerobic microbes by out-competing them, while promoting stronger, whiter roots. By fostering a balanced soil ecosystem, it improves nutrient uptake efficiency and increases plant resilience to stress and disease. It can be applied as a root drench, foliar spray, or brewed into a living microbial solution for maximum activity.
A concentrated blend of fungi and bacteria that builds a living root environment for healthier, more resilient plants.
