About This

  • 🌞【Premium Material】Automatic window opener is made of aluminum alloy, maximum window opening: 45cm/17.7inch. Maximum opening about: 30°. Maximum opening weight: 7kg/15lb. Size: 38 x 9.5 x 9.5 cm / 14.96 x 3.74 x 3.74 inch (appr.)
  • 🌞【Double Spring Design】Compared with the single spring vent, the double spring greenhouse window opener has stronger thrust force, more solid, and much durable.
  • 🌞【Solar Heat Sensitive】Non electric, our window vent opener uses solar energy. The automatically adjusted temperature is 15 to 25°C. When the temperature exceeds 25 degrees, the window regulator will remain open. The temperature drops to 15-18 degrees Celsius and the opener will close completely.
  • 🌞【High Performance】As the temperature changes automatically, maintains the best growing temperature and prevents your greenhouse from overheating.
  • 🌞【Ideal for Your Greenhouse Window】The greenhouse window opener can be clamped onto or screwed onto your greenhouse frame, opens and closes your greenhouse window.

    Loved the wildflower seed mix—sprouted fast, and the pollinators showed up within a week. Great way to help the bees!

    The cedar raised beds I ordered from GARDUCT smell amazing and feel rock‑solid. Absolutely worth every penny compared to the flimsy ones at big‑box stores.
