Vegetable farmers choose greenhouse films based on the thickness of the film, because thicker films are easy to use and have a higher thermal insulation effect. If the location of the greenhouse is a rainy and windy area, we recommend that you choose this thicker film, because this film has a strong protective effect, is not easy to damage, and is easier to maintain.
If the greenhouse is planted in an arid and rainy area, then a relatively thin film should be selected, which is not only conducive to the photosynthesis of crops, but also cheap and reduces unnecessary expenses.
Most of the greenhouse films in the past were colorless and transparent. With the development of science and technology, light blue films have become the mainstream. In addition, films in black, purple, pink, yellow and other colors have also been born. Colored films can change the nature of light in the greenhouse.
Compared with colorless films, colored films can increase the yield of vegetables and reduce pests and diseases. For example, yellow films have a significant promoting effect on the growth of cucumbers, but light blue films can increase the yield of coriander but reduce the yield of cucumbers.
