Need some vent automation for your extra heavy, double glass, greenhouse vent? The Bayliss Super Solar Vent Opener has you covered. This handy device uses solar power to automatically open your extra heavy greenhouse vent when things get too warm, and it closes back up when it cools down. No batteries or electricity required—it’s like having a built-in thermostat for your plants!
