Welcome to the Bayliss XL Auto Vent Opener, a great little gadget that just might revolutionise your current greenhouse growing space.

Automatically Opens and Closes

This ingenious garden gadget automatically opens and closes hinged vents in order to provide your greenhouse plants with sufficient ventilation at all times.

How does it work?
