Mini & Small Frame Polytunnels

Compact tunnel covers for rows, beds, and hobby-scale growing
Sort by:

Extend your growing season and protect your valuable crops from unpredictable weather with our compact range of mini and small frame polytunnels. Designed for home gardeners, urban growers, and backyard vegetable patches, this collection provides an ideal, controlled microclimate for nurturing seeds, propagating cuttings, and safeguarding sensitive plants.

Constructed from robust, galvanised steel frames and heavy-duty, UV-stabilised polytunnel covers, our structures are built to withstand the elements while offering exceptional tear resistance. The compact footprint makes them perfectly suited for tight spaces, raised garden beds, or allotment plots, while roll-up zippered doors ensure easy access and optimal ventilation control.

Mini and small-frame polytunnels extend the season over beds or rows without a full-span tunnel. They pair well with hoops or light frames and are popular for vegetables, cut flowers, and trials.
