The special diamantled surface ensures a 60% higher light refraction than a traditional biano/black cloth and comes to reflect up to 97% of total light. The use of a reflective cloth inside the grow room is highly recommended because it allows you to make the most of the light emitted by the lamps. The special diamantling, in addition to increasing light reflection, allows to eliminate dark or hot-spots. Absolutely obscure, it guarantees a total absence of infiltration of light from the outside. Covered in PET for greater robustness and anti corrosion and anti wear effect, with special membrane that prevents it to bend.
