Roof Accessories Greenhouse Supplies

The Automatic Vent Opener was designed to automatically control the temperature in all Canopia Greenhouses. As the air inside the greenhouse warms, the vent gradually opens to allow the correct amount of air flow into the greenhouse and closes when the optimal temperature is reached. The vent arm was designed with the use of natural wax that expands as the air gets warmer, to push a piston that raises the window, then contracts as it cools, closing with the use of a spring. The Automatic Vent Opener operates without the use of electricity.

I purchased the automatic roof vent for my 6' W x 10' D Hobby Greenhouse that I bought from Wayfair thinking it would fit but it did not. I was told that I had to pay the shipping although it was within the 30 days of purchase. Is that normal?. Blanche. Augusta, GA. Tue Apr 09 2024
