Abstract

A method for controlling a light intensity in an enclosed cultivation space, the enclosed cultivation space having a light regulating system including an artificial light source for emitting artificial light, the method comprising, detecting a first fluorescence gain and a second fluorescence gain at different light intensity operating points. If the fluorescence gain is greater when the light intensity is greater, then the light intensity setpoint can be increased. Similarly, if the gain is greater when the intensity is lower, then the setpoint can be reduced. The invention is based on the understanding that it is beneficial for plant growth to provide light at a level which corresponds to a maximum ChIF-gain. The light level which corresponds to a maximum ChlF-gain provides a good trade-off between production rate and production efficiency.
