Multi Span Hydroponic Tunnel Plastic Cover Greenhouse

From a geographical point of view, in addition to using this kind of greenhouse for winter in the southern region, it can also keep warm at night in spring and autumn. In summer, the agricultural film is removed and used, and the film is generally replaced every year. The northern area uses a film and quilt warm shed to resist the severe cold in winter, and the same simple large shed as the southern area can also be used for heat preservation at night in spring and autumn.

During the day, the quilts are rolled up to heat up by the sun, and the quilts are put down for heat preservation at night. The other three sides can be made of earthen wall, brick wall or insulation board. The brick wall and insulation board can be made into two Layer, better thermal insulation performance. Multi-span film greenhouses are generally equipped with external shading, internal shading, top ventilation, side ventilation, fan wet curtains and other conventional temperature and humidity adjustment equipment. Its advantage is that it is highly expandable, such as automatic sprinkler irrigation, soilless cultivation, heating All can be installed as high-end equipment of the glass greenhouse according to customer needs.
