Greenhouse lighting surface of the transparent cover material: To adopt light, no drops, dust, insulation performance good prices for agricultural steel sheds, and has a strong tensile membrane longevity. Winter and spring in order to maintain a certain temperature level of agricultural greenhouse steel shed, vegetable ensure normal growth temperature, if necessary, would require heating. According to weather and temperature changes in agricultural steel sheds ventilation manufacturers, sunny fast heating, ventilation may be early, overcast snow slow warming, ventilation can be late.
