Features greenhouses: the lighting conditions. The higher the large greenhouse, shed vertical irradiance greater the difference shed new composite materials cost, irradiance and the upper floor of the shed difference of up to 20-30%. In the winter season to shed light conditions prolong things better than the north-south elongated shed light conditions as well shed new composite material construction, local lighting conditions much different. But things irradiance greenhouses extend north and south sides of the difference can be up to 10-20%. Features greenhouses: the lighting conditions. In the period covered by the film due to dust pollution will greatly reduce the transmission rate of new composite materials, greenhouses, two days after the use of the new film, dust pollution can reduce the transmission rate of 14.5%. 10 days will be reduced by 25%, 28% or less after a half lower. In general, due to dust pollution can reduce the light transmittance of 10-20%. Severe pollution, the amount of light shed by only 7%, while the resulting degree can not be used.
