Auto Vent Opener Kit for Eden Ecogrow and Grand Gardener greenhouses
Auto Vent Openers automatically control the temperature and humidity levels in your greenhouse. It also provides additional ventilation, making gardening easier. This is because you won’t have to worry about opening and closing the vent manually. As the air inside the greenhouse warms, the vent gradually opens to allow the correct amount of air flow into the greenhouse and closes when the temperature cools. The vent starts opening at 12-15 degrees. The vent arm was designed with a metal cylinder containing wax. This expands when heated to push a piston, which raises the window. All you need to do is to install it on your roof vent window and it automatically starts working. The Automatic Vent Opener also operates without the use of electricity. It is compatible with all our greenhouse range.
