The Original Highland Super Strength Polytunnel

Do not be fooled by other suppliers using our brand name 

If you're looking for a commercial-grade greenhouse, the 14ft super strength garden polytunnel is a great place to start. It offers ample space with a height of 7'.6'' at its apex, making it a great choice for growers who need plenty of room. The hoops are spaced 5ft apart as standard, which provides better strength than other models that space their hoops 6ft apart to save costs. The dimensions of the polytunnel are 14ft x 25ft (4.27m x 7.62m). The standard kit comes with everything you need to get started, including 50.8mm hoops, timber base rails, four diagonal brace bars, ground tubes for soil, timber end frames, anti-hot spot tape, two single sliding timber doors, and a SuperTherm Cover that comes with a 7-year guarantee. The kit also includes a full set of crop bars and two extra ridge bars for added strength. You can also add some additional extras to your greenhouse, such as side ventilation with a roll-up screen, galvanized staging along one or both sides, overhead irrigation, irrigation timers, and ground cover weed suppressant.
