Best-Selling Greenhouse Roof Vent Kit - Manual or Automatic

Better airflow for your Best-Selling Polycarbonate Greenhouse

Add fresh-air ventilation and help release excess heat with a roof vent designed specifically for the Best-Selling Polycarbonate Greenhouse.

The vent integrates directly into the curved polycarbonate roof and opens up to approximately 17 inches, allowing rising hot air to escape while fresh air circulates through the greenhouse. Its galvanized metal frame and polycarbonate panel are designed to match the greenhouse structure for a secure, coordinated fit.

Compatibility: This roof vent is designed only for the Best-Selling Polycarbonate Greenhouse. It is not compatible with the Classic Arch, Nordwood, or other greenhouse models.
