Features greenhouses: temperature conditions. The arrival of spring season shed and exposed to gradually increasing the temperature difference between the greenhouse construction steel factory, warming up to 6-15 ℃. Steel greenhouse cost, minimum night temperatures in winter than in open sunny 1-3 ℃ high steel greenhouse, a few cloudy days and exposed to the same subjects. Therefore, the main greenhouse production season for spring, summer and autumn. Through the insulation and ventilation and cooling can Pengwen maintained at optimum growth temperature of 15-30 ℃. Features greenhouses: the lighting conditions. The higher the large steel-framed greenhouses greenhouse construction, irradiance shed greater the difference in the vertical direction, the upper and ground irradiance shed up to 20-30% of the difference. In the winter season to shed light conditions prolong things better than the north-south elongated shed light conditions as well, the local light conditions much different. But things irradiance greenhouses extend north and south sides of the difference can be up to 10-20%.
