Specification: One pack of 6 mil polyethylene film 25x8 ft. Service life of three yearsThe 5 layer technology in our UV resistant greenhouse plastic allows it to have high mechanical strength and flexibilityOur greenhouse film is designed with a high 90% light transmittance. This is the amount of light that is able to pass through your greenhouse. High light transmission is essential to allow your plants to thriveAnti Drip: Containing anti dropping agent. These properties cause water droplets to flatten and run down the sides of the greenhouse instead of landing on the plants themselves. When water lands on the plants, this can lead to the plants burning due to the light interacting with the water on the plant's surface. Too much water can also lead to pests, which then lead to disease and stunted growth. Note that the agricultural film will not be very clear, or even a little hazyYou can use our greenhouse sheet to also cover your grow tunnel, yard mini greenhouse or garden for vegetables, flowers, fruits, herbs or more!
