4m x 3m Polytunnel Greenhouse Roll Up Windows Wolf Poly Tunnel

The Wolf 4m x 3m x 2m Polytunnel is a more compact alternative to the 6m version, suited to smaller gardens and allotment plots where a full-size structure would dominate the space. It still delivers the same core function — protecting vegetables, fruit, and tender plants from wind, rain, frost, and pests while extending the growing season at both ends. The 140gsm UV-protected polyethylene cover is fully enclosed to hold humidity for tropical or moisture-loving plants, and 8 roll-up mesh windows provide ventilation and visual access to growth without letting insects in.

The zipped roll-up door gives straightforward walk-in access for day-to-day planting and management, and the 25mm galvanised steel frame resists rust through repeated seasons outdoors. Four wind ropes and ground nails anchor the tunnel, and the cover's extended edges are designed to be buried into soil for a sealed fit. At this smaller footprint, the structure is easier for one person to anchor and manage, making it a practical entry point for allotment growers or anyone without space for the larger model. As with all Wolf polytunnels, avoid acidic chemicals near the cover, as they can cause damage.
