Product Description

With no batteries or electricity required, the auto vent opener is completely powered by the sun, being able to open a roof vent through temperatures between 15-degrees and 25-degrees - adjustable to your growing requirements.

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