Lacewing™ Essential Automatic Vent Arm Window Opener / Autovent

The autovent window opener is an all-in-one solution for greenhouse temperature control. Using a cleverly designed pressure system, the arm opens the window if the greenhouse is over a preset temperature, and closes the window below this temperature. Care for your greenhouse plants, even when you're not at home.

All greenhouses need to be well ventilated on hot and sunny days to keep plants in optimum growing conditions. The automatic vent arm uses captured gas which expands in hot temperatures, opening the window without any running costs. The simple but smart mechanism will maintain optimal temperatures at all times, whether you are or aren't at home. You can adjust the opening temperature between 15° and 20°C to suit your individual needs. Simply install the vent opener by using the instructions and let it do its job.
