Greenhouse ventilation management: Spring outlet size can not be completely defined by a particular data because different greenhouse structure, timing and speed of cooling is different. Camber larger greenhouses, as appropriate camber shed surface heat flow easily along the upper part of the discharge of greenhouse films, even small mouth monomer leaked steel shed cost, but also to achieve better results leaked. And the longer the low planting years old shed, because greenhouse camber smaller shed surface is relatively flat, hot air shed leaked discharge port speed from slow monomer steel shed construction price, greenhouse temperature is high . Typically, this will be at the top of the greenhouse leaked mouth open to 40 cm wide, only with a higher altitude, camber larger greenhouses open to the same outlet 30 cm leaked effect. The main types of greenhouses: toward choice. Beyond the frozen layer is appropriate, greenhouse basic design is based on the geological structure of the cold regions and local climatic conditions determined on a regional basis crisp relatively deeper soil. Extend beyond the 70-meter wall recommended to stay joints, the back wall of the greenhouse according to the nature of the greenhouse use, leave some ventilation windows, ventilation for winter use. Rainbow greenhouse masonry walls to be capped under the former arch embedded parts, for use when installing arch. Greenhouse wall height according greenhouse span, generally eight meters across the back wall height 2.5 m greenhouse is appropriate. 7.5 m height of 2.3 meters across the back wall of the greenhouse is appropriate.
