【Automatic Greenhouse Window Opener】 Use solar energy to open or close the greenhouse air intake when the temperature rises or falls, and is fixed on the greenhouse rod, no perforation requires high-quality construction

【Load Application】 The maximum window opening is about 45cm, depending on adjustment and load. Open roof windows, suitable for greenhouse windows up to 7kg (if they are over 7kg, we recommend opening with two window openers)

【Automatic switch】 This opening device will automatically open and close the greenhouse windows because the temperature changes automatically, maintaining the best growing temperature and preventing the greenhouse from overheating

【Spring Control】 When the temperature exceeds 25°, the open window will continue to open. Once the temperature drops to around 15°, the opener will close completely

【Tips】 Do not apply excessive load by locking or covering windows. The automatic ventilation window of the window opener in the greenhouse cannot be used in an environment with a temperature above 50°
