Root Roids™

Root Roids™ from Dr Greenthumbs is a potent root-stimulator blend of mycorrhizae and nutrient-solubilising beneficial bacteria that colonises roots fast, boosting nutrient uptake, vigour and resilience. These arbuscular mycorrhiza fungi create a vast living network that expands root surface area and unlocks phosphorus and micronutrients, delivering thicker stems, quicker growth and heavier yields in soil, coco or hydro. Inspired by Jeff Lowenfels’ soil-food-web philosophy of teaming with microbes, Root Roids lets you grow bigger, cleaner crops with less bottled fertiliser and no chemical fuss. 

Dust Root Roids into transplant holes or blend into media when up-potting with our GreenSpace range, and watch plants establish in days, not weeks. Trusted by Australian growers for organic integrity, dr greenthumbs backs every order with fast nationwide delivery and a money-back guarantee, so your garden never misses a beat. Start teaming with microbes today and experience living-soil power that turns good gardens into great ones.
