What is the optimal thickness for greenhouse film? Which type of greenhouse film is better? The greenhouse film produced by Dongguan Shuotai Industrial Co., Ltd. has high transparency and fast heating. The crops are launched one month earlier. When choosing greenhouse film, the first thing to consider is the transparency, tensile strength, and toughness of the film. It is recommended to use 8 silk in the south and replace it in the same year, because the quality of the greenhouse film in the second year is not a problem, but the light transmittance is low, which will delay the release of crops.
