Bayliss MK7 Automatic Roof Vent Opener

The Bayliss MK7 Automatic Roof Vent Opener is a robust and efficient solution designed to automatically regulate greenhouse temperature.

Built to handle heavier vent frames, it opens up to a maximum of 12 inches, helping to release excess heat and maintain optimal growing conditions. The opener is filled with a special wax that expands as the temperature rises, gently pushing the vent open without the need for electricity or manual effort.
