Do not rush to change new plastic film

Many farmers thought that new plastic film will be better for plants growth. They usually replace their old films timely in August.
If you change your plastic film in August or earlier, it is not good for plants growth for that at noon the sunshine is strong, but the new plastic film is of high light transparency, causing the greenhouse internal high temperature. And the vegetables are more easier to get diseases which will make your management become difficult. In addition, the strong sunshine will shorten the service life of your new plastic film. When it is in the winter, the plastic film will be polluted by dust or other factors during several months using, the light transparency will become weak. Therefore, the plants will not get enough sunshine for growth.
So, early or late changing the plastic film is not good to manage your greenhouse.
