What Is A Greenhouse Window Opener

A greenhouse vent opener allows you to control the air and humidity inside the greenhouse by opening or closing greenhouse windows. When the temperature is too high, you should open the greenhouse window to allow air circulation, allowing the plants to cool and get the proper humidity.

There are different types of greenhouse window openers. An electric window opener will require batteries or a power line to operate, while manual window openers do not require power. However, you have to manually open the windows when it gets hot and close when it is cold.

Automatic window openers use a wax cylinder, which expands in hot weather and contracts in cold weather. The expansion and contraction move a piston that opens and closes the window.
