Plastic Film Greenhouse
Flexible plastic films including polyethylene,
polyester and polyvinyl chloride are used as covering material in this type of
greenhouses. Plastics as covering
material for greenhouses have become popular, as they are cheap and the cost of
heating is less when compared to glass greenhouses. The main disadvantage with
plastic films is its short life. For
example, the best quality ultraviolet (UV) stabilized film can last for four
years only. Quonset design as well as
gutter-connected design is suitable for using this covering material.
