This nifty roof vent opener works like magic to keep your greenhouse at the perfect temp. It's got a metal cylinder filled with a special mineral that gets bigger with heat, pushing a piston to open your roof vent. Cool down time? The mineral shrinks back, and a spring shuts the vent, making everything ready for the next warm-up. It's all smooth and gradual, ensuring your plants get the ideal breeze for cooling off.
