Why we recommend this
Often a strong fit for
- Protecting frost-sensitive plants
- Starting seedlings early in the spring
- Large garden allotments
- Growing tropical or high-humidity plants
This spacious walk-in polytunnel is designed to extend your growing season, providing a controlled environment that protects plants from the cold while maintaining necessary humidity levels. With a footprint of nearly 4 metres in length, it offers ample room for large-scale gardening and plant management.
- Galvanised Steel Frame: Constructed from heavy-duty galvanised steel that is resistant to rust, corrosion, and peeling for long-term outdoor use.
- Reinforced Stability: Features two additional supporting rods to strengthen the build, providing more stability than standard tunnel designs.
- UV-Resistant PE Cover: The green mesh cover allows nourishing sunlight to reach your plants while protecting them from harsh weather and maintaining high humidity for tropical varieties.
- Adjustable Ventilation: Equipped with a large roll-up window on each side to facilitate cross-ventilation on hot days and manage internal temperatures.
- Large Walk-in Access: The 184cm high zipped door provides easy entry for gardeners and equipment, making it simple to tend to your crops.
Built for practicality, this greenhouse uses a fully closed waterproof cover to create a sheltered microclimate. The galvanised frame ensures the structure remains sturdy, while the roll-up windows serve a dual purpose of air circulation and pressure reduction during warmer periods. It is a functional solution for gardeners looking to start seedlings early or protect established plants from frost.
Please note that this structure is intended for general garden use and is not suitable for extreme or bad weather conditions.
