Description

Extra roof vents are the simplest upgrade for a greenhouse that runs hot in summer. Each vent swings open up to 17 inches to let warm, humid air out through the roof while cooler air comes in through the doors.

The automatic version adds a bimetallic opener that reacts to temperature on its own; the manual version is opened and locked by hand.
