Only the best for your grow



Xtreme Gardening MYKOS® is a pure, granular root‑zone enhancer composed of the arbuscular mycorrhizal fungus Rhizophagus intraradices. Designed to form a symbiotic network of hyphae around plant roots, MYKOS® drastically boosts nutrient and water uptake, acting as an extension of the root system for more efficient resource absorption.
Ideal for both hobbyist and advanced growers cultivating vegetables, fruits, herbs and flowers, MYKOS® promotes vigorous root development, reduces transplant shock, and supports resilience in both heavy clay and sandy media. It is compatible with synthetic and organic fertilisers, as well as all common growing substrates including soil, coco and rock‑wool.
With a high concentration of 300 living propagules per gram, this single‑species inoculant ensures strong colonisation without inter‑microbial competition. It helps plants endure drought or heat stress and can improve long‑term soil structure and nutrient cycling.
