Abstract
A glasshouse is a place where you can produce a local climate which is largely independent of the conditions of the outdoor climate.
Horticulture uses greenhouses to overcome conditions which are unsuitable for an outdoor crop or to cultivate plants which are not normally found in our latitudes.
Horticultural research frequently uses greenhouses to solve horticultural problems.
While it is of no great importance to the practical man whether temperature and flow of air are uniform in the glasshouse the man making experiments must put the highest demands on the uniformity of each of the component parts which form the climate so as to be able to eliminate sources of error.
By heating, ventilation, and irrigation combined with use of the modern automatic regulation it is nowadays possible to produce a certain desired climate in the house.
The uniformity of the climate obtained in the house depends on how well the house closes, the place where the constant temperature control is suspended, and on its precise working.
It was the aim of our investigation to measure the uniformity of the temperature in our experimental greenhouse.
Knowledge of this matter provides a proper basis to plan experiments.
Furthermore we wanted to find out whether by the use of fans we could obtain a more equal temperature of the house.
