Gigavent - Automatic Greenhouse Vent Opener Replacement Cylinder

This is for the Cylinder ONLY.

The Gigavent is a heavy duty ingenious temperature-sensitive devices automatically open and close cold frame lids, greenhouse windows and even skylights throughout the day and maintain a constant interior climate, something impossible to achieve by manual adjustments.

Requires no batteries or electricity, it starts opening between 55 to 75°F, depending on how you have adjusted the vent. Strongly recommended for all our glazed season extenders because it dramatically improves plant growth. Screw directly into polycarbonate panels, wood, or metal frames.

After a few years of usage, the cylinders can start to die on the gigavent. This is a replacement cylinder so you will not have to replace the entire Gigavent.
