The Automatic Louver Vent Opener automatically controls temperature and adds ventilation in Palram greenhouses. As the air inside warms, the vent gradually opens to let in the right amount of airflow, then closes again once the optimal temperature is reached. The vent arm uses natural minerals that expand with heat to push a piston and raise the window, then contract as it cools, closing the vent with a spring. It operates entirely without electricity.
