Dr Greenthumbs Root Roids Boost (Bacillus Inoculant)

A pure Bacillus inoculant that floods the root zone with beneficial rhizobacteria to improve nutrient availability, root vitality, and overall plant performance. It’s made from organic, living ingredients and slots neatly into any existing feed program. Internally, we think of it as the “pure Bacillus” option—especially handy when you’re reusing or refreshing older soil.

Targeted Bacillus species plus supporting aminos and calcium. That combo supports everything from germination and early root development to flowering and fruiting (think stronger cell walls, better chlorophyll production, and added resilience).

• Transplant: 1–2 scoops per plant
• Early veg: Dose again at the start of veg
• Pre-flower: Hit it once more about a week before flower starts
• Ongoing: Reapply monthly during active growth; every two months when growth slows

• Coco / soilless: 1–2 scoops per plant at transplant; follow the schedule above
• Organic soil: Same rates and timing as coco
• Propagation (seedlings/cuttings): About ½ scoop per 5 L of potting mix; gentle monthly top-ups during active growth

No. Boost doesn’t supply P or K directly. It helps cycle nutrients already in your medium. If you’re chasing bloom P&K, run a dedicated source alongside it.

You can do a very light soak, but it isn’t essential. These microbes really shine once roots are present. You’ll usually get more value mixing Boost into the potting media or applying at transplant.

Yep. Boost is compatible with common nutrient programs and other beneficials. It works in soil or coco and pairs well with the rest of the Root Roids range.

Faster root establishment, improved nutrient uptake, richer green foliage from increased chlorophyll, sturdier growth, and better overall resilience.

After the transplant/early-veg/pre-flower applications, switch to a monthly maintenance dose in active growth. In slower periods, every two months is fine.

Totally. Quick guide:

• Orange (Boost): Pure Bacillus—great for reusing/refreshing soil and general rhizosphere vigor
• Black (Original): Full-spectrum microbes for regular top-ups via watering
• Blue (Granular): Mycorrhizae-only granules to mix into fresh media or use at repot Many growers mix blue into new soil, then top up through the cycle with black or orange as needed.

While it’s aimed at soil and coco, coco/soilless growers love it at transplant and in early vegetative growth to kickstart biology. In hydro, use sparingly and monitor filters/lines if you choose to experiment.

Yes—30-Day Money Back Guarantee. If you’re not satisfied, return it with at least 50% of the contents for a full product refund.

Keep it sealed, cool, and dry. Avoid heat and moisture, and don’t leave the lid open—this preserves microbe viability between uses.
