Measurements during the fifth crop of The Perfect Chrysanthemum showed that the light efficiency is highest during the 3rd and 7th week. That is mainly because of the leaf area. A low leaf area during the first weeks do not intercept all the light. The high leaf area (LAI>4) during the last weeks of the crop give too little light for the lower leaves.
