THE CLIMATIC CONDITIONS IN THE HORTICULTURAL GREENHOUSES AT FREJUS

R. Portal
Several flower greenhouses have been studied in the Fréjus area. These greenhouses belong to different growers, have been built recently and are used for growing the same variety of rose - "Sonia".

The study of the climate in these greenhouses in summer and winter - essentially temperature, humidity and light - enables us to determine the efficiency of the means, e.g. ventilation, heating, shading, watering used by the horticulturist to modify the greenhouse climate.
