Abstract:
On the first workshop on greenhouse construction and covering materials in Hannover 1986, a new plastic-film greenhouse construction developed by the ITG Hannover was presented (1).
The disadvantages of usual plastic-film greenhouses were defined and the requirements for the construction of such houses were deduced (2).
The construction, the film, the fastening of the film, the stretching of the film on the construction and the ventilation as part of the construction belong to the system plastic-film greenhouse construction.
The construction of the ITG has been further developed in the last years and different suggestions have been made to it's use in various climatic zones.
Some climatic investigations have been made in the unheated greenhouses.
