Unique Temperature Control Function: Unlike other products, our top roof vent of the green house is equipped with 2 rods. One of the rod can automatically adjust the angle of the window according to the actual temperature. When the temperature reaches 10℃, the window slowly closes, and when it reaches 35℃, the window opens to a maximum angle of 35°. The other rod can manually adjust the window angle according to your requirement. Premium Cedar Wood: Made by high quality Cedar Wood, this green house has certain insect-proof capabilities that can withstand long time use. Plus, it is in good stability that is not prone to severe cracking or distortion. Multi-Layer PC Panel: We provide inserted pc panels to facilitate customers to install this outdoor greenhouse. These panels not only mimic natural light distribution, but also effectively filter out over harmful UV rays, shielding plants from sun damage while promoting uniform growth from seedlings to maturity. Spacious and Useful Gardening Space: You'll find plenty of space in our pc greenhouse to grow a variety of flowers, vegetables, and plants. It's also perfect for storing tools and equipment, making it both a practical garden room and a special retreat for unwinding. And an additional vent to allow for ventilation when the windows are closed.
