The Gigavent is a temperature-sensitive device that automatically opens and closes cold frame lids, greenhouse windows and even skylights throughout the day to maintain a constant interior climate.  Requires no batteries or electricity, it starts opening between 55 to 75°F, depending on how you have adjusted the vent. We strongly recommended installing this product with all glazed season extenders as temperature regulation dramatically improves plant growth. Screw directly into polycarbonate panels, wood, or metal frames.

Use the Standard Vent Opener to lift up to 15 lbs, Megavent to lift up to 26 lbs and the much stronger Gigavent, with all metal black and silver construction, to lift up to 65 lbs.
