Greenhouse – Automatic Vent Opener

As a company with over a decade of experience in selling thousands of greenhouses and accessories we have collectively made many modifications to improve our designs making our products some of the best on the market.

WARRANTY 1 YEAR MANUFACTURER, T & C’s see stores/ warranty page.


Works automatically from Wax, when it heats up it expands pushing out the piston, and when it cools down it contracts and the springs pull the window shut tight.

Start to open at 18C to 20C

Fully open temperature 26C or above

Rotate the cylinder clockwise to lower the open temperature.

Ventilation in your greenhouse will enable growth and healthy disease free plants

No battery or electricity required.

Highly recommend to automate vents down at least one side of greenhouse to promote air flow within the greenhouse.

Allows you to not worry about having to open and shut your vents.
