This product is a replacement cylinder to fix an automatic vent opener for the GardenHouse greenhouse.

Automatic vent operators on the roof and base vents require no electricity or batteries. The vent operator contains a paraffin (wax) that expands when the temperature reaches about 65°F, pushing the vent open to its fully opened position at about 85°F. As it cools and the paraffin contracts, the operator’s springs draw each vent closed. It is adjustable within approximately 5°F and easily detachable for manual operation.

This product is only the replacement cylinder, click here if you wish to purchase a new automatic vent opener for your GardenHouse greenhouse.

Please allow two weeks for delivery. Only available for shipment to continental U.S. addresses.
