Finally followed a survey of existing methods and those developed by van den Muijzenberg from his experiences with temperature (heating, cold treatment) and light (SD treatment, LD treatment, artificial light supply). Eleven methods were described for different year periods, by different environments and environmental changes to get a year-round culture. Three methods of eliciting several yields a year were elaborated.
