This walk-in backyard greenhouse tent creates a large space for you to start seeds and protects plants from fluctuating temperatures, helping extend the growing season and end winter woes in milder climates. It has large, zipped roll-up doors that provide easy access to the garden greenhouse and mesh sidewalls that keep out unwanted winged creatures; multiple openings allow for cross ventilation, putting temperature and humidity control in your hands. The greenhouse is equipped with a two-layer 140 GSM PE cover, which has a reinforcement grid through the middle to prevent tearing, protects plants from UV scorching, and allows 85% of nourishing sunlight to pass through uninterrupted. This large greenhouse features a steel structure composed of five crossbars, two diagonal braces, and a reinforcing ground frame—all made of water-safe, bend-resistant galvanized steel; the top is formed into an arch shape, which prevents sagging and enhances stability against wind and rain, and for added support, you can bury the extended edges deep in the soil and pull guy ropes tightly from the ground stakes. It is recommended that 2 people assemble the greenhouse.
