Multi-Span Greenhouse, cost-saving and convenient to use, is a kind of equipment for cultivation or breeding that is constructed simply. The greenhouse has great space-efficient performance and strong ventilation ability, also preventing the heat loss and the intrusion of cold air.

The ventilation in the middle of each span of the greenhouse can be used for large area ventilation. 
At the same time, due to the principle of thermal pressure difference, the high temperature gas in the greenhouse is always at the highest point of the greenhouse, so the natural ventilation of the traditional greenhouse can be changed. 
Effectively reduce the temperature and humidity in the greenhouse, especially suitable for flowers and crops that do not require high humidity.
