This automatic greenhouse vent opener will allow air to circulate through the greenhouse when its hot, and then it closes when the temperature cools

Working via a temperature sensitive cylinder that expands when hot, the opener operates between up to 50 degrees centigrade to regulate the temperature in the greenhouse between 16 to 25 degrees centigrade

Coming complete with detailed installation and operational instructions, the vent requires some assembly to set up, however once installed it is completely automatic.
