The Bayliss Solar Powered Vent Opener helps to regulate the temperature in your greenhouse. These vents expand and contract based on the adjustable operating temperature between 55 and 75F (13-24C). Upgrades are available for hot-houses or for high-wind areas. Replacement cylinders are available for purchase with a one-year warranty.
