10. Yosoo

Lifts 15 Lbs, Yosoo Automatic Window Opener, Solar Heat Sensitive Automatic Thermofor Window Opener Greenhouse Auto Vent Opener Standard

Yosoo - As the temperature changes automatically, maintains the best growing temperature and prevents your greenhouse from overheating. The best way to keep a stable greenhouse temperature is by installing an automatic vent opener.

They allow thermostatic ventilation control through the roof windows of your greenhouse. If you’re using your greenhouse in the shoulder seasons, or even in the summertime, an autovent can prevent your plants from essentially baking to death in a solar oven. Then the autovent will open using a hydraulic system, similar to how a truck is lifting a dumpster.

Ideal for your greenhouse window--opens and closes your greenhouse window. The idea is simple – the autovent is usually closed – except when the internal greenhouse temperature rises above a certain level. With the automatic window openers, you can be sure of an even temperature in your greenhouse day and night.
