FAQs

  • How long does it take to sanitize a standard grow room?

    • 10,000 sq ft room can take up to 16 man hours

    • This includes setup, fogging, breakdown, and room H2O2 concentrations back to normal permissible exposure limits (PEL)

  • Is H2O2 toxic at any level?

    • Personnel may be in the room with air purifying respirator protection at concentrations greater than 1 part per million (ppm) not to exceed  75 PPM.

    • The PEL limit of 1 ppm is based on irritation data not toxicity data.

  • How do we know the fogging will kill the organism to give us a higher yield?

    • Using our Biological indicators (BIs) placed throughput the facility we can verify that the facility is free of mold, fungus, mildew up to a 6- Log kill

    • We use stainless steel BIs inoculated with 6-Log (more than a million) Geobacillus Stearothermophilus These are a benign relative and accepted simulant to anthrax spores (Bacillus Anthracis).

  • Can you clean between harvests and during the regular grow season?

    • We can sanitize grow rooms in between harvests at a higher concentration H2O2

    • If we are to sanitize in the grow room during harvest, we can adjust the concentration of H2O2 as needed based on pilot program data

  • Do you test for viable contamination?

    • MES can do viable testing through third party labs using standard MES Standard Operating Procedures (SOPs)

    • The client can do their own viable testing pre/post fogging if preferred.

  • How soon after fogging can we use the room?

    • The three factors which impact facility re-entry are 1) Size of a room 2) Amount of H2O2 used in treatment and 3) Facility ventilation system flow.

    • Treated areas are monitored for airborne hydrogen peroxide. Re-entry occurs when levels are below 1 ppm.

    • Best case scenario is to fog over a weekend when personnel not on site and room can get the best dose of fogging

  • What is OMRI Listed mean?

    • The Organic Materials Review Institute (OMRI) is a private, nonprofit organization that determines whether or not a product qualifies as organic under the USDA’s National Organic Program (NOP). Goods that are found to comply are listed on theOMRI Brand Name Products List (BNPL).
