Product Description

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

Gigavent - Automatic Greenhouse Vent Opener up to 65 Lbs Review

This solar vent opener works great and is very sturdy. We have it on a 4 foot by 8 foot coldframe lid (2 x 2 wooden frame, corrogated plastic glazing). Although the marketing photo appears to show a cold frame, this vent is really designed for installation from the inside of a greenhouse. We have a large and deep cold frame so probably could have climbed inside to install it, but wanted to be able to remove the lid in the summer when our region sometimes gets high winds and it is warm enough we don't need the glazing. To solve the problem, we installed removable hinges on the hinge side (those on typical doors would work well, with the removable pins) and a detachable plate on the front side that the vent attaches to. The detachable plate can also be removed to fully open the lid for easy planting, without removing the hinge. Without this customizing, it would be hard to reach into this large cold frame through the vent opening, especially in cold weather!
