A spacious walk-in polytunnel designed to provide a controlled growing environment for vegetables, fruits, and plants. This 4m x 3m structure features a unique design with roll-up side panels, offering significantly more ventilation options than standard models.
- Roll-up Side Walls: Both side panels can be lifted completely, allowing for maximum airflow and easy access to crops from either side of the structure.
- Galvanised Steel Frame: The skeleton is constructed from galvanised steel for rust resistance, reinforced with four diagonal support slants for improved structural stability.
- Reinforced Mesh Cover: The durable plastic mesh cover protects plants from light weather and pests while allowing essential sunlight to reach your crops.
- Twelve Mesh Windows: Equipped with multiple mesh-screened windows to facilitate cross-ventilation while keeping insects out.
- Zipped Walk-in Door: A large, zipped front door provides easy entry for gardeners and plenty of clearance for moving tools and large pots.
This polytunnel provides nearly 12 square metres of growing space, making it suitable for larger garden plots or allotments. The combination of the zipped door and twelve windows allows for precise temperature management, which is essential during peak summer months. The frame is secured using ground stakes and guy ropes to ensure the cover remains taut and stable.
Built for practicality, the walk-in height of 2 metres ensures a comfortable working environment for taller gardeners and provides enough vertical space for climbing plants like tomatoes or cucumbers. The white mesh cover is designed for durability, diffusing harsh sunlight to prevent scorching while maintaining a warm internal climate.
