Root Roids is Dr Greenthumbs’ flagship biostimulant and one of Australia’s most trusted root zone enhancers. It combines a synergistic blend of arbuscular mycorrhizal fungi with a diverse range of nutrient‑solubilising bacteria to establish a thriving living ecosystem around the root zone. These beneficial microbes form symbiotic relationships with plants, dramatically increasing root surface area, unlocking bound nutrients, and improving the uptake of water and minerals. The result is accelerated vegetative growth, stronger stems, and healthier, more resilient plants that consistently yield higher quality harvests.
Root Roids is designed for versatility and performance. In soil, it stimulates microbial biodiversity and improves long‑term soil health. In coco, it prevents common nutrient lockouts and helps shorten vegetative cycles. In hydroponics, growers frequently report 7–10 days faster veg times, visible plant responses within 48 hours, and fertiliser savings of up to 25%, thanks to more efficient nutrient uptake. Its clean, easy‑to‑use formulation dissolves quickly, leaving no residue, making it system‑safe for hand watering, automated irrigation, or foliar applications.
By promoting healthier root systems, Root Roids doesn’t just drive faster growth, it enhances plant resilience against stress, boosts terpene and flavour production, and creates the foundation for bigger, denser, and more aromatic flowers. Whether you’re a hobby grower or a commercial producer, Root Roids is the one‑step microbial inoculant that unlocks the full potential of your plants.
Rapid Root & Growth Activation
Mycorrhizae and bacteria colonise the rhizosphere, pushing explosive root and canopy development.
Nutrient Savings & Efficiency
Proven to reduce fertiliser requirements by 15–25% while increasing growth rates.
System‑Safe Versatility
Completely soluble and safe for soil, coco, and hydroponics.
A living inoculant that delivers faster growth, healthier plants, and bigger yields.
Contains Rhizophagus irregularis mycorrhizae and multiple nutrient‑solubilising bacterial strains.
Creates a dense microbial colony that improves nutrient cycling and plant uptake.
Produces visible growth responses in 48 hours under optimal conditions.
Shortens vegetative cycles by 7–10 days, helping to streamline production.
Saves 15–25% on fertiliser costs in hydroponic systems.
Fully soluble, system‑safe, and leaves no residue, ideal for tanks, irrigation, or foliar.
Enhances root health, stem strength, and canopy density for better flowering potential.
Self‑buffering formulation, pH rises slightly on mixing but stabilises naturally in the root zone.
Directions for Use
expand_more
Coco / Soilless Media: Apply ½ – 1 scoop per L of water weekly through veg and flower.
Soil: Apply ½ – 1 scoop per L of water weekly from vegetative through bloom stages.
Hydroponics / Water Culture: Use ½ scoop per L of Water fortnightly in active recirculating systems. In passive systems, replace the solution after 48 hours.
Propagation (Seedlings & Cuttings): Apply ¼ scoop per L of water as a root drench once roots are visible.
Foliar Spray: Mix ½ scoop per L of water. Spray at night or with lights off and allow 10 hours of rest. Apply fortnightly. Note: product may stain surfaces.
Tips
Stop using in coco one week before flush for a cleaner finish.
Always add Root Roids last to the nutrient mix after pH adjustment.
Do not re‑adjust pH if it rises, Root Roids self‑buffers in the rhizosphere.
Store sealed in a cool, dry location away from direct sunlight and moisture.
