This tent greenhouse has a 140 GSM PE cover that maintains high humidity levels, protects plants from UV scorching, and lets 85% of nourishing sunlight through—you can use a single cover during warmer months and add a second one once it starts getting colder to protect your plants. This mini greenhouse creates an isolated space to shield plants from fluctuating temperatures, helping extend the growing season and end winter woes in milder climates. It features zippered roll-up sidewalls for easy access to the greenhouse, and multiple openings allow sufficient ventilation, putting temperature and humidity control in your hands. The outdoor greenhouse comes with a sloped top to prevent sagging, and you can bury the ground frame and extended edges deep in the soil for better stability against wind and rain.
