INTEGRATED OPTIMIZATION OF TEMPERATURE, CO₂, SCREEN USE AND ARTIFICIAL LIGHTING IN GREENHOUSE CROPS USING A PHOTOSYNTHESIS MODEL

A leaf photosynthesis model is suggested for integrated optimization of temperature, CO₂, screen use and artificial lighting in greenhouse crops.
Three different approaches for the optimization are presented.
First, results from greenhouse experiments with model based optimization are presented.
Second, a model-based analysis of a commercial grower’s production possibility is shown.
Third, results from a simulation of the effect of a new lighting strategy are demonstrated.
The results demonstrate that it is possible to optimize plant production by using a model-based integrated optimization of temperature, CO₂, and light in the greenhouse.
