Cannabis/Hemp Greenhouses and Cold Storages see the benefits
Ethylene Control’s EC-3+ Clean Air Machine controls mold/mildew, removing ethylene, and more. Our new improved Super Fresh Media has been proven to remove ethylene gas, control mold, rots, listeria, bacteria, and also eliminate cannabis/hemp odors.
Ethylene gas has many interesting aspects, both positive and negative. Little data exists regarding cannabis and ethylene gas, but the application or buildup of the gas in most plant-growth stages can be detrimental. It can inhibit growth, maturation, and cannabinoid and essential oil production.
Ethylene Gas Plant Symptoms:
- Leaf yellowing
- Epinasty (a plant part is bent outward and often downward)
- Abscission (the natural separation of flowers, fruit, or leaves from plants at a special separation layer)
- Flower senescence (the growth phase in a plant or plant part (such as a leaf) from full maturity to death) and abscission
- After an independent study at the University of Davis, research reported that the removal of ethylene gas is critical to prevent concentrations that exceed the threshold for "ethylene injury."
Sources of Ethylene Gas
- Ripening fruit
- Decomposed plant material
- Plant growth regulators
- Any form of combustion ie: engines, heaters
- Heating systems are the most common combustion contaminant
- Automotive emissions, plastics, smoke, and fluorescent lights
- Propane-powered forklifts
Cornell University Greenhouse Horticulture Findings
Longer exposure to high concentrations of ethylene can result in:
- Stunted growth
- Deformed or chlorotic leaves
- Decayed flowering and plant death
Ethylene Stages
- Jorge's Cannabis Encyclopedia states that, if ethylene is applied pre-flower it may increase the number of female plants. This is done through the placement of high ethylene-producing fruits below the leaf level. It is important to remove the ethylene-producing fruits when the sex is set.
- Ethylene removal equipment should then be used to tame the amount of ethylene gas in the greenhouse.
- Due to its ability to remove rots and molds, ethylene removal filters can be used in rooms for storage and drying.
- Basically, ethylene may have its place early in growth but should be removed through stage progression.
Customer Quote
“The EC-3+ clean air systems are doing great for our Hemp in the storage rooms. There was a drastic change in the odor from one day to the next. We didn’t run the EC-3’s until day 2 and on day 3 you couldn’t smell anything from the outside of the closed area. I dare to say they also helped with mold/mildew control as well, I sometimes have seen issues with Hemp/Cannabis at the humidity levels we were asked to keep in the storage rooms.”
