LUMISOL CLEAR provides excellent clarity and transmits 92% of the light crops use to grow and develop. In the UK where light levels can be lower, LUMISOL CLEAR allows more light to enter which in turn can bring picking time forward.In addition to its temperature control properties Lumisol Clear manipulates the type and level of light entering the greenhouse to significantly improve crop hardiness, colour, taste and shelf-life.
