Single tunnel film greenhouse is also called spring-autumn greenhouse. The greenhouse only has one arch, which is the most simple film greenhouse. It is mainly composed of greenhouse structure, film cover and ventilation. Although this greenhouse can resist big wind and big snow and its winter thermal insulation is also not good, in early spring, it can harvest the vegetable in advance and in late autumn, it can extend the vegetable harvest time, to get better economic benefit.
The single tunnel film greenhouse width is usually 4m to 10m and the standard is 8m. The greenhouse length is usually 20m to 100m. The film cover thickness is usually 120 microns, 150 microns or 200microns.
