Why we recommend this
Often a strong fit for
- Small to medium gardens
- Allotment vegetable growing
- Extending the spring and autumn growing seasons
- Protecting young plants from birds and pests
This compact walk-in polytunnel greenhouse provides a controlled environment for growing vegetables, fruits, and plants in smaller outdoor spaces. With a 1.8-metre square footprint, it offers ample room for internal customisation while remaining manageable for urban gardens and allotments.
- Reinforced Three-Layer Cover: The plastic shell includes a middle reinforcement grid for added durability and an anti-UV coating that permits 85% of natural sunlight to reach your plants.
- Ventilation and Access: Features mesh windows to allow for essential air circulation and a large zipped door that can be rolled up and secured for easy walk-in access.
- Stable Steel Construction: The strong steel frame is designed with an arched roof to reduce the risk of water sagging and improve the overall structural integrity.
- Ground Anchors Included: Supplied with four ground ropes and four stakes to help pin the structure securely into the ground for added stability.
The interior layout is completely open, giving you the flexibility to arrange shelving, potting benches, or grow bags to suit your specific gardening needs. The 200cm peak height ensures most gardeners can stand comfortably inside, making daily plant care and maintenance much simpler. To ensure the frame and cover are correctly tensioned and secured, assembly by two people is recommended.
