The Automatic Roof Vent Opener is one of the most popular accessories available for your Grandio greenhouse. The opener is adjustable and helps to keep your plants well-ventilated without any manual opening or closing.
The opener replaces the manual vent arm, and the elegantly designed, mineral-filled cylinder expands when heated. This pushes a piston will automatically open and close your vent window as the temperature changes.
The roof vent will start to open as the temperature inside your greenhouse reaches 70°F and is fully open at about 80°F. It is designed to install in just minutes and will make keeping your plants at an optimum temperature a simple task.
