Sulfur, when mixed with air, creates sulfur dioxide which may damage certain parts of a plant growth chamber. Sulfur dioxide can corrode metal and alloys causing damage to these components. Piping, cooling/heating coils and wiring made of copper and or aluminum within the chamber can all be affected by higher concentrations of sulfur dioxide and may cause unwanted control issues, chamber shutdowns, and leaks.
What should you do?
Options are available to include additional coatings that will help protect air flow coils and piping, that can be purchased at the time of the chamber design and will reduce the risk of damage due to corrosive gases such as sulfur sioxide.
Facility preparation: If your chamber is already performing sulfur burning, we advise you do so under the following room conditions to limit the dispersion of the sulfur to only the plant growth area of the chamber with the following settings:
- Lights off
- Circulating fans off
- Temperature control off
- Humidification off
- Exhaust fan off
- Exhaust and fresh air dampers closed
- 10 min delay period prior to fumigation cycle
- Fumigation power/burn time period activated for maximum of 5 minutes.
- Dampers held close for minimum 8 hours after burn period complete
It is recommended that if sulfur burning is required to be used in the chamber, that NO more than 224g/m² or 0.75oz/ft² of sulfur every 14 days be introduced into the growth space. Excessive use of sulfur dioxide in short duration or high concentration of sulfur dioxide will cause both room and equipment damage. Failure to follow the above recommendations could cause chamber malfunctions and will void warranty on the product.
