Why we recommend this
Often a strong fit for
- Large allotments and garden spaces
- Cultivating tall crops like tomatoes and vines
- Gardeners needing high-volume ventilation control
- Extending the growing season for vegetables
This large-scale walk-in polytunnel provides nearly 18 square metres of protected growing space, ideal for gardeners looking to extend their growing season and cultivate a wide variety of vegetables, plants, and flowers. Built with a focus on structural stability and plant health, it features a spacious interior that allows for easy movement and flexible planting layouts.
- Galvanised Steel Frame: The core structure is made from galvanised steel for improved strength and resistance to rust, supported by slanted bracing tubes for added stability.
- Reinforced 140gsm Cover: The durable PE plastic cover features an internal reinforcement grid to protect plants from UV rays and light weather while retaining heat.
- Triple-Door Access: Three roll-up doors provide exceptionally easy access for gardeners and equipment while allowing for maximum airflow.
- Six Mesh Windows: Integrated windows ensure consistent ventilation to regulate temperature and humidity, with mesh screens to keep pests away from your crops.
- Stability Kit Included: Comes complete with four ground stakes and four guy ropes to help secure the greenhouse to the ground.
The 6-metre length of this polytunnel makes it a practical choice for serious home growers or allotment owners. The walk-in design ensures you have plenty of head height to work comfortably, and the open layout allows you to organise your pots, raised beds, and shelving exactly how you need them. The green cover helps the structure blend into garden environments while providing the necessary light transmission for healthy growth.
For those managing large batches of seedlings or tall-growing crops like tomatoes and cucumbers, the triple-door system is particularly useful. It allows for cross-ventilation during hot summer months and provides multiple entry points so you don't have to traverse the entire length of the tunnel to reach your plants.
