Automatic Vent Kit
The Automatic Vent Opener will help keep your Palram Greenhouse ventilated even when you are not at home. Designed to replace the manual vent, the simple, oil-filled cylinder will automatically open and close your vent window as the temperature rises and falls. The Automatic Vent Opener will start to open as temperatures inside your greenhouse reach 68 degrees F and will be fully open at 80 degrees. It installs quickly and easily and will provide care-free ventilation for your greenhouse.
