Description The classic "big semicircular polytunnel" that with modern techniques continues to satisfy the needs of horticulturists, nurserymen and tobacco growers. The structure is basically the same as that of the polytunnel greenhouse with straight sides and a curved roof, but with lateral posts that are curved like the roof arches. It is particularly used in the case of terraced cultivation systems and in mountainous regions with problems of high winds and/or snow.
