The Automatic Vent Opener from Canopia by Palram is designed to automatically control the temperature and humidity levels of your greenhouse. It provides additional ventilation for all Canopia greenhouses, making gardening stress-free.

As the air inside the greenhouse warms, the vent gradually opens to allow the correct amount of airflow through the greenhouse until the optimal temperature is reached. The starting opening temperature of the arm is between 12°-15° C.

The vent arm was designed with the use of wax which expands with heat and contract when it cools, meaning you don't have to worry about installing electricity cables or expensive temperature sensors.
