Automatic Vent/Window Opener for Greenhouse

Automatic Greenhouse Vent Opener – Hassle-Free Climate Control

Take the guesswork out of greenhouse ventilation with this Automatic Vent Opener by Canopia. Designed to maintain the ideal temperature and airflow inside your greenhouse, this clever device opens and closes your roof vent automatically—no electricity required. It’s the perfect low-maintenance solution for protecting your plants from overheating, especially during spring and summer.

Self-Regulating Temperature Control

The opener works by using a heat-sensitive wax piston that expands and contracts based on the internal temperature. Once the temperature rises above 12–15°C, the arm starts to open the vent gradually, allowing excess heat and humidity to escape. As the greenhouse cools, the vent closes again—completely automatically.
