The Hybrid Polytunnel offers customers a maximum ventilation growing environment with standard 3m straight sides, using 80mm x 80mm box section stanchions and internal spacings on 16ft (4.9m) to give greater growing or sales area. Aluminium gutters are standard with optional aluminium and polycarbonate doors. Roll up side vents are an optional extra, (automation is feasible but at an additional cost). The structure can be used using single or twin skin polythene methods. This structure can also offer a plant sales canopy solution for retail nurseries and farm shops that do not require full retail classification.
