ABSTRACT:
The invention relates to a method for controlling the temperature in a controlled-climate chamber, wherein: an organism, such as a plant or an animal, is placed in the controlled-climate chamber; the temperature in the controlled-climate chamber is kept essentially constant at a specific value (T1); at least one growth characteristic (G) of the organism, such as, for example, the CO2production, is measured; the temperature in the controlled-climate chamber is raised or lowered by a specific value (δT); the magnitude of the growth characteristic is measured again; the variation in the measured value of the growth characteristic is determined (δG); and the temperature in the controlled-climate chamber is adjusted, depending on the variation in the measured value of the growth characteristic (δG) that has been determined.
