Root Roids Granular is Dr Greenthumbs’ premium mycorrhizal inoculant designed to supercharge root development and plant vigour, naturally. The dust‑free granules deliver a concentrated blend of arbuscular mycorrhizal fungi on a clean organic carrier, establishing a symbiotic network that dramatically increases effective root surface area. This boosts nutrient and water uptake, improves stress tolerance, and helps plants establish faster after transplant. Safe for propagation with no burn risk, the granules are simple to mix into fresh media, sprinkle into planting holes, or broadcast around existing root zones.
By enhancing the rhizosphere, Root Roids Granular supports stronger stems, fuller canopies, and healthier, more productive plants. It integrates seamlessly with organic programs and works in soil, coco, and even biologically managed hydro setups. Use on its own or alternate with Fruit Roids to push both root performance and flower quality.
