Halls Greenhouses Auto Louvre Window Opener

A must-have accessory for any greenhouse with a louvre window, the Halls auto louvre opener opens and closes a louvre by itself as the outside temperature changes throughout the day.

As the temperature drops, especially as dusk approaches, the auto opener closes the louvre window back up to ensure that your plants inside the greenhouse stay nice and warm overnight.
