In 1976 the hothouse horticultural production in the food zone belonging to Łódź urban administrative province was concentrated mainly in provinces of Łódź, Kalisz, and Piotrków. The glasshouse production was strongly developed glasshouse area per one inhabitant of towns was 70 per cent higher than the national average. On the other hand, production under foil was insufficiently developed. Distribution of glasshouses, hotbeds, and foil tunnels was characterized with a big spatial differentiation. The hothouse area was mainly used for cultivation of vegetables, first of all tomatoes and cucumbers. Production of vegetables per one inhabitant of towns exceeded by over 40 per cent the national level. Forecast of the horticultural production development till 1990 envisages that the hothouse area will reach 700 ha, with the biggest exparasion to be noted in the case of foil tunnels and the smallest in hotbeds. The highest increment rate will be observed in provinces of Konin and Włocławek, and the smallest in those of Łódź and Kalisz. Production of vegetables will grow two-and-a half fold, and will reach the level of 36,000 ton. It will be mainly coming from provinces of Łódź, Piotrków, Kalisz, and Konin. In the long run disproportions in spatial distribution of the hothouse horticultural production will be reduced.
