Quonset type
This is a
greenhouse, where the pipe arches or trusses are supported by pipe purling
running along the length of the greenhouse. Usually, the covering material used
for this type of greenhouses is polythene. Such greenhouses are typically less
expensive than the gutter connected greenhouses and are useful when a small
isolated cultural area is required. These houses are connected either in free,
standing style or arranged in an interlocking ridge and furrow.
