Denver & Colorado · Grow Room Sanitation
Powdery mildew and botrytis don't lose to a wipe-down. Dry ice blasting takes them off benches, racks, walls, and coils with nothing added — no chemicals, no water, no spike in the humidity you already pay to remove.
Every assessment includes a contained test patch when conditions allow — watch one bench section come clean before you commit a dollar.
The pattern
Powdery mildew and botrytis sit in rack threads, bench undersides, wall texture, and coil fins. A wipe-down clears the smooth surfaces, misses the harborage, and the pressure is back by the next cycle — so you clean the same room again, and again.
Every chemical carried into a grow room is something that can end up on surfaces your product touches — one more thing to log, track, and answer for. The cleanest compliance position is nothing applied in the first place.
Pressure washing and mop-downs dump moisture into a room where you pay, every hour, to pull moisture out. A humidity spike after cleaning hands mildew exactly the conditions it was waiting for.
Every day a room sits in turnover is a day it isn't growing. A reset that needs dwell time, drying time, or an airing-out period pushes your whole calendar back.
Method fit
Dry ice pellets freeze surface growth brittle and lift it off as the pellet flashes into gas. Benches, racks, walls, drip line exteriors, dehumidifier coils, duct exteriors — cleaned where they stand, no teardown, no soaking.
Because the blast medium disappears as CO₂ gas, there's no residue left behind and nothing added that a test could find. No moisture enters the room, so your environmental controls never see the cleaning happen. When we're done, the room is dry and ready to flip — no dwell time, no re-entry wait.
Cycle turnover
Between-harvest resets work best as a standing appointment, not a scramble. We schedule around your harvest dates and keep the paper trail for you.
Book the reset for the window when the room is empty. We work your turnover days — the room comes back on your timeline, not ours.
Contained blast of the emptied room: benches, racks, walls, coils, duct exteriors. No dwell time, no drying period, no airing-out wait before the next cycle loads in.
Dated before/after photos and job notes for the compliance file, in your inbox before the invoice. Recurring slots are bookable, so sanitation becomes a calendar item with its own paper trail.
We're surface decontamination, not pest control and not your IPM program. Live plants leave the room before we work — dry ice is for the empty room between cycles, not the canopy. And mildew pressure comes back if the environment that grew it doesn't change: we take the growth off your surfaces, and our job notes flag what we see along the way — the sweating duct, the struggling dehumidifier, the corner that never dries — so your team can fix the conditions. Fix the environment, and the reset holds.
