The most suitable lighting for raising pigs in a greenhouse is the lighting of a single-slope greenhouse: a single-slope greenhouse means that the entire sunny side or the lower half of the greenhouse roof is covered with plastic film.
The upper half and the back side are tile structures, with a long front slope and a short rear slope. The front wall is high, and it is semi-open after the film is removed in spring, summer and autumn. It has a simple structure and is easy to cover with film. It has good wind and snow resistance and thermal insulation properties. Generally, farmers' pig houses can be filmed with a little modification. The lighting area is large and the building The requirements are strict, the cost is high, and the wind resistance, heat preservation, and pressure resistance are poor. In summer, the roof must be covered with a sunshade, so it is suitable for large pig farms.
