Why we recommend this
Often a strong fit for
- Compatible 6m x 3m tunnel frames
- Year-round vegetable and herb growing
- Allotments and large gardens
This 6m x 3m greenhouse replacement cover provides a practical way to restore your garden tunnel when the original plastic becomes worn or damaged. It is designed to fit standard 6m x 3m x 2m frames, allowing you to maintain a protected environment for vegetables, fruits, and herbs without replacing the entire structure.
- Reinforced PE Material: The durable polyethylene cover protects plants from light wind and rain while trapping heat to support healthy growth.
- Integrated Ventilation: Multiple roll-up windows with fasteners are located on both sides to help regulate temperature and airflow.
- Easy Access: A large zipped front door rolls up and stays in place, making it simple to walk in and out with tools or trays.
- Enhanced Stability: Features an extra 15cm of material on all edges, which can be buried in soil or weighed down to keep the cover secure.
- Simple Attachment: The cover attaches directly to your existing frame using the included tape for a stable and straightforward installation.
The cover is made from green PE mesh, which is lightweight yet effective at creating the necessary conditions for year-round gardening. The 200cm height provides ample headroom for walking inside and tending to taller plants. Please note that this cover is designed for standard use and is not suitable for extreme weather conditions. Ensure you measure your existing frame before purchase to confirm compatibility.
