Antimicrobial Treatment • Product Contact/No Residual • Most Effective Oxidant • Most Cost Effective Cleaning

The GRO3 Ozone Treatment System provides antimicrobial/sanitization solutions, specifically designed and calibrated for the medical, legal, and recreational marijuana industry. The systems provide an environmentally friendly innovation to eliminate pests, bacteria and mold from growing facilities while reducing or eliminating the need for harsh chemicals or pesticides.

The GRO3 Ozone Treatment System was originally designed for the medical marijuana industry, but has since expanded into the recreational sector as food/drug safety standards have become more stringent. The GRO3 Ozone Treatment System was developed from existing Advanced Ozone Integration technology, which has been servicing the food and beverage industry for years with successful installations for major clients including Pepsi, Nestle, Sun Pacific, and Sysco Foods.
