PLASTIC – FILM – GREENHOUSES DISADVANTAGES – DEMANDS – TYPES

If we speak and think about the development of plastic-film-greenhouses we have to consider:

• the construction,

• the film,

• the fastening of the film,

• the stretching of the film on the construction

• the ventilation as part of the construction.

Existing plastic-film-greenhouses have some disadvantages.
But especially for vegetable growers glassgreenhouses become more and more too expensive and uneconomic.

For Mediterranean areas and also for middle Europe we have to search for greenhouses, which are cheap enough and suitable for part-time production during the winter in the south and during the summer in the north.
These can be plastic-film-greenhouses.
But we have to overcome the existing disadvantages.

In this paper the disadvantages will be pointed out and some demands for the future development of plastic-film-greenhouses will be derived.
Then some construction types, conventional examples and trend of development for some countries will be shown.
In this paper only the construction and not the other above mentioned parts will be considered.
