Dry Ice Blasting for Greenhouses & Indoor Cultivation
Greenhouses and indoor cultivation operations are tough cleaning environments. Water creates mould and electrical hazards. Chemicals threaten plant material and produce certifications. Abrasive media is out of bounds anywhere near food crops. Dry ice blasting solves the entire problem at once.
What we clean in greenhouses
- HVAC and ventilation — Fan housings, blade assemblies, vent stacks, ducts
- Lighting systems — Reflectors, fixture housings, ballasts (cleaned without water around live electrical)
- Heating equipment — Boiler externals, distribution lines, radiator surfaces
- Electrical panels and motor controls — Dust, biofilm, salt deposits — non-conductive cleaning
- Conveyor systems, packing and grading equipment — Plant residue, soil, biofilm
- Greenhouse glass and structural framing — Algae, biofilm, paint overspray, sealant residue
- Crop changeover deep-cleans — Full equipment reset between cycles
- Pathogen control — Physical and thermal disruption of biofilm without solvents
Why dry ice for cultivation
No water. Wet cleaning encourages mould, pythium, and powdery mildew. It also doesn’t mix with the dense electrical systems running heat, lights, fans, irrigation, and CO₂ enrichment.
No chemicals. No solvent residues to flag in produce certifications. No reentry intervals. No risk to the next crop cycle.
Plant-safe. CO₂ pellets sublimate. Nothing falls into the canopy that has to be vacuumed or mopped out around live plants.
Cold-shock biofilm disruption. -78°C disrupts pathogens and biofilm physically without solvents.

How a typical greenhouse cleaning project runs
Most greenhouse work is scheduled between crop cycles — the changeover window when one crop has been cleared and the next planting hasn’t started. ODIB sends certificate of insurance and operator credentials before mobilization. On site, the crew works through structural steel, racking, irrigation lines, and benches. The big advantage: no moisture introduced into a humid environment that’s already prone to condensation and mould pressure.
Pricing
Greenhouse work is typically quoted day-rate because contamination level varies dramatically by facility age and crop history. A two-person crew with full equipment runs $2,200–$3,000/day in Southwestern Ontario. For larger greenhouse operations and multi-bay scheduling we contract for the full season turnover. See our cost guide for typical ranges.
FAQ
Will the cold damage glazing or polycarbonate panels?
No. We direct the blast away from glazing and use a softer pressure setting near any panel surface. Structural steel, racking, irrigation hardware, and floors take the blast without issue.
Can you clean between active crops?
Not typically — the change-over window between crops is the right time. Some operators do greenhouse cleaning during off-bay shutdowns where one section is empty while adjacent sections are still in production.
Is this CFIA / cannabis-compliant?
For cannabis production facilities the cleaning approach aligns with Health Canada cultivation standards: no chemical residue, no moisture, no media in the production space. CFIA-inspected food crops are handled the same way.
Does dry ice handle algae and biofilm?
Yes. Algae, biofilm, mineral scale, and growth-medium residue come off cleanly. For heavy biofilm we may do two passes — the first lifts the bulk, the second polishes the surface.
