18FT Wide Conventional
21 years online - still growing strong
Our 18ft wide polytunnels provide substantial protected growing space for nurseries, farms, smallholdings and professional growers. Designed for larger-scale growing, these commercial polytunnel kits offer generous working height and plenty of room for crops, plants, staging and equipment. Manufactured by Direct Plants in our own workshops in England, the range is available in a choice of lengths to suit different sites, growing requirements and levels of production.
An 18ft wide polytunnel provides the capacity needed for more ambitious growing projects, giving you extensive covered space for crops, nursery stock and protected production. The conventional curved profile combines generous internal height with a practical growing area, making the range suitable for both professional and large-scale domestic use.
Our 18ft polytunnels are manufactured using heavy-duty galvanised steel frames and quality polythene covers, with each kit produced by our own team. As growers ourselves, we understand the importance of creating a practical working environment with sufficient room for planting, crop management and day-to-day access.
If you require a slightly smaller structure, our 14ft wide conventional polytunnels provide an excellent alternative, while our 14ft straight sided polytunnels maximise usable height around the edges of the tunnel. You can also browse our complete range of garden and commercial polytunnels to compare all available sizes and designs.
