Three targeted microbial formulas, three growth stages — a unified system built on published cannabis research. Dry, shelf-stable, no cold chain.
Most "cannabis" inoculants are crop-generic PGPR with a new label. Ours aren't. Every strain we use is validated in published PGPR and cannabis research — root colonization, bulking-phase biology, late-flower root-zone support — with strain selection informed by studies on cannabis itself where the data exists.
The rhizosphere is where the real work happens — Trichoderma afroharzianum root colonization, Bacillus velezensis and B. subtilis establishing in the root zone, and a living microbial community around the roots through every stage of the grow.
Each pouch vacuum-sealed, dry, ready to mix into your reservoir or apply as foliar. Same pouch format. Same dosing. Different microbe blend for every growth phase.
Four organisms selected for root development, rapid colonization, and early-growth nutrient uptake. Built around the highest Trichoderma load in our lineup.
Six organisms weighted for the flowering demand window. Re-inoculates the root zone as veg-phase populations decline, through weeks 2–4 of flower. Designed to follow VEG BOOST as phase two of the program.
The finisher, reformulated. Three organisms, no fungi — Trichoderma needs weeks to colonize, so the finisher puts everything into the bacteria that can still work in the time left.

Follow the Bonsai Complete system from transplant to late flower. One pack per phase. No guesswork.
Accelerate root development, colonize the rhizosphere, establish nutrient uptake. This is first contact — heaviest inoculation where it matters most.
Root-zone support through the flowering demand window. Re-inoculates during weeks 2–4, when veg-phase populations naturally decline.
Late-flower root-zone support. A bacteria-only blend for the weeks when the root-zone population built in veg and early flower needs its last top-up.
Stop microbial application. Your plants harvest the colonization you built over 8 weeks of the Bonsai system.
This market is the hardest it's been in a decade. Wholesale prices cut in half. Input costs climbing every quarter. A lot of what sits on the shelf is crop-generic PGPR in cannabis packaging — strains picked for broad-acre agriculture, formulated somewhere else, sold by companies with no one in a flower room.
Bonsai is the opposite. Every strain in every pouch was chosen from published research — cannabis studies where they exist, PGPR literature where the mechanism applies. Every dose is priced so real growers can actually afford to run it. Every formulation decision is made by a grower still in the rooms with you — not a marketing team, not a distributor, not someone who's never flipped a plant in their life.
Made in Canada. Made for this market. Made for the growers who built it.
Cannabis microbial inoculants haven't changed in 15 years. We built the category's first legitimate upgrade.
Not marketing. Not anecdote. Published data on Trichoderma and Bacillus performance in cannabis and hemp — reported with the caveats the papers actually carry.
We continuously track research-backed cannabis microbial research from the labs that actually study this plant — Punja (SFU), Backer (McGill), Frontiers in Plant Science, MDPI Plants, World Journal of Microbiology, and ongoing studies from active cannabis research groups. Every strain decision traces back to current published science, not marketing claims from 1995 — and our formulas update as new findings emerge.
Browse The ResearchSimple application across any grow style — soil drench or reservoir addition. One pouch treats 1,000L.
Pour pouch into 5–10L water at pH 6.4–6.6. Stir gently until fully dissolved.
Let sit 15–30 min. Our germination-activation chemistry wakes the spores so more live microbes hit the root zone.
Add your fertilizer to the reservoir first, then pH-adjust the final water.
Add microbes last. Apply as soil drench, reservoir addition, or foliar (lights off).
Bonsai Nutrients was founded on the west coast of British Columbia, Canada — by craft growers, for craft growers. We're cultivators who got tired of watching the same companies sell repackaged generic blends at premium prices while growers did all the real work.
We built Bonsai for growers who want to know exactly what they're putting in the root zone — and why. Every formula was born in a grow room, tested on real plants, refined on real harvest results — built around cannabis biology, not marketing ambition.
Every Bonsai formula evolves with the science — peer-reviewed cannabis research, our own grow-room trials, new evidence as it emerges. You're not buying last year's science. You're buying this year's.
