The Canopia Automatic Vent Opener is an essential greenhouse accessory that helps to maintain the ideal growing temperature in your greenhouse. Simply set the thermostat at the optimum temperature and then when the temperature in the greenhouse starts to exceed this, it automatically opens the roof vent to allow the hot air to escape and prevent excessive heat build up. As the temperature cools back down, it automatically closes. The vent opener can be set to open from 12ºC - 15ºC or from your chosen temperature. The Automatic Vent Opener is easy to install and is supplied with full instructions.

  • Programmable
