Outsunny Walk-in Tunnel Greenhouse Steel Frame Pe Cover Uv Protection Season Extender

An arched steel tunnel design sets this walk-in greenhouse apart from basic pop-up shelters, giving plants a protected, full-standing environment across a generous footprint. The dual-layer PE cover and mesh sidewalls work together to manage light, temperature, and ventilation simultaneously — a combination that makes season extension practical rather than just possible.

Features

• Extend The Growing Season: Our walk-in backyard greenhouse tent creates a large space for you to start up seeds and protects plants from fluctuating temperatures. Extend the growing season and end your winter woes in milder climates.
• Roll-Up Doors & Sidewalls: The large, zipped roll-up doors provide easy access to your garden greenhouse, and the mesh sidewalls keep out unwanted guests with wings. Multiple openings allow for cross ventilation, so temperature and humidity are in your hands.
• High-quality PE Cover: Our two-layer 140 GSM PE cover features a reinforcement grid through the middle to prevent tearing. It protects plants from UV scorching while allowing 85% of nourishing sunlight to pass through uninterrupted.
• Steel Structure: Our large greenhouse is composed of five crossbars, two diagonal braces, and a reinforcing ground frame, all made of water-safe, bend-resistant galvanized steel. Formed into an arch shape, the top prevents sagging and allows it more stability against wind and rain. For added support, bury the extended edges deep in the soil and pull guy ropes tightly from the ground stakes.
