Why we recommend this
Often a strong fit for
- Existing 6 x 3m walk-in frames
- Allotments and large gardens
- Extending the growing season for vegetables
Restore your walk-in polytunnel with this durable PE replacement cover, designed to fit standard 6 x 3m frames. This cover provides an effective way to maintain a controlled growing environment for vegetables, fruits, and herbs throughout the year without the need to purchase a completely new unit.
- Temperature Control: The polyethylene (PE) material traps heat and provides protection from light rain and wind, creating a stable climate for healthy plant development.
- Integrated Ventilation: Multiple roll-up windows on each side feature mesh lining to allow fresh air to circulate while keeping out larger pests.
- Secure Anchoring: Designed with 15cm extended edges that can be weighed down or buried deep into the soil to improve stability against light winds.
- Easy Access: The large front door features dual zips for quick entry and can be rolled up and secured with fasteners for convenient access while gardening.
This replacement cover is a practical solution for gardeners whose existing cover has become worn or damaged. The white PE material allows for diffused light, which helps prevent scorching on sensitive plants while still providing the necessary warmth for growth. Please ensure you measure your existing frame accurately before purchasing to ensure a proper fit. Note that this product includes the cover only; the metal frame is not included.
