Important Factors for Plastic Greenhouse Film
Film Life:
Most polyethylene greenhouse film has limited life span due to the degradation processes from the sunlight and heat. The cheap made film is a fairly good choice for seasonal greenhouses. The downside is the growers have to reinvest money and labour to rebuild their greenhouses once in a while.
Huifa uses special films that adds an additional layer of anti-ultraviolet coating which expand the life spand of the film to about 5 years.
Condensate Control:
In another word, anti-drip, condensation can be a serious issue for greenhouses for many reasons. Condensation can affect the light transmission and spreads diseases to plants within a greenhouse. Choose anti-drip greenhouse film is a must for every greenhouse growers.
Light Transmission:
According to “rule-of-thumb”, 1 percent increase in sunlight equals 1 percent increase in plant growth. At Huifa, we use top quality PEP films with 88% light transmission.
