A computer‐controlled spectroradiometer system is described that comprises a commercial spectroradiometer, a low‐cost microcomputer and a purpose‐built interface. The system is used in establishing controlled light environments for the study of plant growth. The method used to link the computer and spectroradiometer is described and an outline of the required control software is given. A set of application programs has been developed to convert the raw spectral data into meaningful physiological/photomorphogenic quantities. This obviates the large volume of manual measurements and calculations that were previously necessary.
