A Walk-in Tunnel Greenhouse is a spacious, elongated structure designed to create a controlled growing environment for plants. Typically made with a durable steel frame and a clear or green polyethylene cover, it protects plants from harsh weather, pests, and fluctuating temperatures. The tunnel shape allows for maximum sunlight exposure and efficient airflow, while the walk-in design provides ample room for gardeners to move around and tend to their crops. Ideal for extending the growing season, it’s commonly used for vegetables, flowers, and seedlings
