Often a strong fit for

- Protecting crops from birds and frost
- Extending the growing season
Designed for large-scale gardening and allotments, this 6 x 3m walk-in polytunnel provides 18 square metres of protected space for growing vegetables, fruits, and flowers. This model features an upgraded structural design, incorporating four additional top rods and a galvanised steel frame to offer better stability and resistance against the elements compared to standard polytunnels.
- Reinforced Galvanised Frame: The core structure is built from galvanised steel for rust resistance, supported by four additional top rods for enhanced stability.
- Durable Hinged Doors: Two metal-framed hinged doors with latches provide easy access and a more reliable closure than traditional zip-up entrances.
- Climate Control: Eight mesh-screen windows allow for consistent airflow and humidity management while keeping birds and larger pests out.
- Weather-Resistant Cover: The reinforced PE plastic cover retains heat to protect against mild frost and allows 85% of sunlight through for optimal growth.
- Secure Ground Anchorage: Features 20cm extended cover edges designed to be buried in the soil to improve wind resistance and overall stability.
The interior height of 200cm ensures comfortable walk-in access, allowing you to tend to tall plants and move around with ease. The transparent green cover includes an internal grid for added tear resistance, ensuring it stands up to seasonal wear. To achieve the best results in windy conditions, it is recommended to bury the extended edges deep into the ground or secure them with heavy weights.
Assembling this structure requires a firm foundation. Due to the size of the 6-metre frame, a two-to-three-person assembly is recommended to ensure the galvanised steel components are correctly aligned and the cover is tensioned properly.
