HORTICULTURAL SHEETING Sterilite HDF 7.3 metres wide Thermal Grade 5 metre length

 With U.V. stabilizers for extended outdoor life. All our Tunnel width sheeting is classed as 4 season material, advanced features including IR Blocking to reflect out some of the heat producing lightwaves and lower greenhouse heat on hot days, High Diffusion and Heat Retention ingredients scatter light and retain heat overnight,  plus a special anti condensation additive which causes water to run down the cover as a thin film instead of forming droplets - this reduces the spread of disease and damage to flowers. This material is UV blocked up to 380nms for reduction of aphids, botrytis and mildew, saving on chemical use. Good for organic growing. Light transmission 89%.
