Why we recommend this
Often a strong fit for
- All-season vegetable cultivation
- Gardeners needing full walk-in access
- Larger garden plots or allotments
- Protecting frost-sensitive plants
This large-scale walk-in polytunnel is designed for year-round cultivation, providing a protected environment for plants, vegetables, and flowers. With a generous footprint and 2-metre internal height, it offers ample space for staging and easy movement while working.
- Spacious Walk-in Design: Provides a significant 10.5 square metre growing area with a high ceiling, allowing for comfortable access and room for taller plant varieties.
- Controlled Ventilation: Features six roll-up mesh windows and a zipped front door to manage internal temperatures and ensure fresh air circulation throughout the tunnel.
- Protective PE Cover: The durable plastic shell maintains high humidity levels and protects against wind and rain while allowing essential sunlight to pass through.
- Mesh Protection: The zipped entrance and windows are fitted with mesh to allow airflow while keeping small animals and pests away from your crops.
- Enhanced Stability: Includes 15cm extended cover edges designed to be buried into the ground, reinforced by a steel frame, four guy ropes, and ground pegs.
Built for practical gardening, this polytunnel offers a reliable shield against the elements, helping to extend the growing season from early spring through to late autumn. The 3.5m length provides enough room for multiple rows of crops or a combination of ground planting and raised beds.
The structure is supported by a tough steel frame, though it is recommended that the tunnel is not left standing during extreme weather conditions to prevent damage. Assembly is required, with all necessary fixings and ground pegs included to secure the unit.
