Case studies

Evidence.
Not adjectives.

Six real AirROS deployments — including two independently verified by third-party scientific firms (Emerald Metrics + Intertox). Real CFU counts, real compliance results, real install plans. Full PDFs below.

Primitiv Group

Cannabis cultivation · Niles, Michigan
Primitiv Group

30 of 35 COAs — None Detected.

Challenge

Primitiv — co-founded by NFL Hall of Famer Calvin Johnson Jr. and former Detroit Lions teammate Rob Sims — built their brand on elevated wellness. Hitting non-detect compliance every cycle, across every strain, was non-negotiable.

Solution

Nine AirROS units strategically placed across Veg, five Flower rooms, Dry, Trim, and Hallway. Real-time PPM tuning by stage and strain via on-board ROS sensors.

“It's been a pleasure to have AirROS by SAGE in our grow. We've had thirty non-detect tests for yeast and mold. It's a MUST HAVE!”

Compliance rescue
Cannabis cultivation
Back to Roots

490,000 CFU/g → None Detected.

Challenge

Failed compliance: Yeast & Mold detected at 490,000 CFU/g (limit 10,000) and Enterobacteriaceae 1,600 CFU/g (limit 1,000). Persistent powdery mildew and fungus gnats. Lost product, lost revenue.

Solution

AirROS engineered to facility specs, shipped + installed on-site by the Back to Roots team with live SAGE tech support guidance.

    fungus gnats reported
“For the first time in many years, I can honestly say I see no PM at all. I have not sprayed potions. I have not done anything except fans, AirROS, and temperature/humidity control. I have also noticed a complete absence of all fungus gnats. The AirROS unit and the people at SAGE Industrial have truly given me the will to keep going. I will sell my product with confidence — backed by lab testing that shows no harmful mold, mildew, or any other microbials.”

3rd-party verified3rd-party
Tier II indoor hydroponic cultivation · Portland, Oregon
Killer Green Buds (KGB Farms)

Zero PM. No chemicals. Verified by Emerald Metrics.

Challenge

Validate AirROS in a controlled, third-party study. KGB released their PM SOPs — taking the extraordinary step of letting the room grow without standard mitigation — to test whether AirROS alone could prevent powdery mildew.

Solution

South African Rose Sativa, 60 plants across 6 tables. Hourly multi-spectral imagery via Emerald Metrics' Cannaintelligence system through the entire flower cycle. AirROS tuned to room volume.

“It is strange to work in a cannabis facility that does not smell like cannabis. The AirROS unit eliminates the odor of cannabis completely in the space it operates — a passerby would not recognize a cannabis operation by smell.”

3rd-party odor study3rd-party
Indoor cannabis grow facility · Beaverton, Oregon
PDX Organics

93% odor reduction — independently verified.

Challenge

Validate odor reduction under independent scientific protocol. AirROS contracted Intertox Inc. (Seattle, WA) to design and execute the study using a Nasal Ranger® field olfactometer at 15 sample locations.

Solution

Three sub-objective tests: Levels (D/T before vs after), Time (rate of change), Percent (reduction capability). Sampling May 24-25, 2023 across 1,650 sq ft Indoor Mature Canopy Area #2 plus 11 facility points + a roof background.

7-strain proof
Cannabis cultivation · Michigan
Havi Consortium

Seven strains tested. All passed.

Challenge

Already meeting compliance — initial 100,500 CFU brought down to 70,000+ via retesting — but Havi wanted to set a new industry standard, not just clear the bar.

Solution

Three AirROS units across Veg, Flower, and Dry rooms. Engineered + tuned to room volumes by SAGE. Then tested against seven distinct strains.

Challenge

Boost terpene profile of the Lemon Dosi strain without compromising pathogen control. The customer experience metric — aroma — needed measurable upside.

Solution

Three AirROS units in Veg, Flower, and Dry rooms. Phase 2 ROS (gas-phase H₂O₂ + ≤ 20 ppb ozone) deployed alongside cultivation environment.
