An 18gsm lightweight fleece made from spun bond polypropylene. This super wide width makes it so much easier to cover a large area and its fold down to 1.5mtrs for ease of handling. This thermally insulating fleece protects crops, seeds and young plants against frost and heat, creating optimum growing conditions. The porous construction of the fleece allows the passage of light, air and water. The fabric is UV stabilised making it suitable for use outdoors or for extra protection in unheated greenhouses.
