The industry stopped innovating. We didn't. Three targeted microbial formulas, three growth stages — one unified system engineered specifically for cannabis biology.
Most "cannabis" inoculants are crop-generic PGPR with a new label. Ours aren't. Every strain we use has peer-reviewed data on this plant — root colonization, bulking-phase biology, late-flower defense.
The rhizosphere is where the real work happens — Bacillus subtilis ISR signaling, Trichoderma harzianum root colonization, B. megaterium IAA-auxin production, and P-solubilization that unlocks fertilizer your plant can actually use.
Three core principles engineered into every pouch. Every strain decision, every additive ratio, every gram of carrier — chosen with cannabis biology as the target.
Every strain selected from published research, not marketing. Real data from real cannabis studies — Punja 2024, McGill Backer lab 2025, Frontiers in Plant Science 2023. We cite our sources.
Three formulas matched to Veg, Flower, and Late Bloom biology. The microbes your plant needs in week 1 are not the same microbes it needs in week 6. We designed for that.
Vacuum-sealed dry pouches. No fridge needed. Consistent CFU every application. No carrier-liquid dilution. No viability decline after opening. The format that actually works.
Cannabis microbial inoculants haven't changed in 15 years. We built the category's first legitimate upgrade.
This market is the hardest it's been in a decade. Wholesale prices cut in half. Input costs climbing every quarter. Most "cannabis" products on the shelf are crop-generic PGPR with a new label — formulated somewhere else entirely, never validated on cannabis biology, sold by companies that have never flipped a plant in a real flower room.
Bonsai is the opposite. Every strain in every pouch was chosen from peer-reviewed cannabis research. 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.
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 strains tuned for explosive root development, rapid colonization, and early-growth nutrient uptake. The highest CFU load in our lineup.
Six-strain consortium for internodal development, bud site formation, and nutrient availability during the bulking window. Strain ratios weighted toward flowering-phase biology — P-solubilization, ISR signaling, nutrient mobilization.
Six-strain late-flower formula built around T. harzianum, B. licheniformis, and B. pumilus — resilience-focused species that peak-perform during weeks 5–6 when late-flower plant stress is highest. Supports terpene production and resin quality through the finish.
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.
Internodal development, bud site formation, P-solubilization through the bulking phase. Strong plant health support during flowering.
Late-flower plant health and resin quality support. Aids terpene production through the finish.
Stop microbial application. Your plants harvest the colonization you built over 8 weeks of the Bonsai system.
Not marketing. Not anecdote. Real published data on Trichoderma harzianum and Bacillus spp. performance in cannabis cultivation.
We continuously track peer-reviewed 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.
Browse The ResearchPhase-specific microbes for every stage of cannabis growth. Dry. Vacuum-sealed. Built on the west coast of British Columbia.
Simple application across any grow style — soil drench, reservoir addition, or foliar spray. Every pouch treats 1,000L at standard dose.
Pour pouch into 5–10L water at pH 6.4–6.6. Stir gently until fully dissolved.
Let sit 15–30 min. L-alanine germinants trigger Bacillus GerA wake-up cascade.
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 the growers chasing real terpene output, real resin quality, real flower density. Every formula was born in a grow room, tested on real plants, refined on real harvest results — built around cannabis biology, not marketing ambition.
We're currently in CFIA registration and selling through craft-cultivator channels while we complete our approval path. Grower trust — not hype — builds the category.
