This study was conducted to determine the effects of supplementary lighting intensity and duration on selected Cassulaceae species grown in a hydroponic system. Five subfamilies in Crassulaceae with corresponding species were chosen as experimental units namely Sedeveria ‘Letizia ’, Sedum ‘Sun Red’, Crassula rupestris, Echeveria ‘Momotaro’, and Graptoveria opalina. Light duration (3 and 6 hours) and intensity (4,000 lux or 60 μmol • m−2 • s−1 and 8,000 lux or 120 μmol • m−2 • s−1), and their combinations served as factors which were replicated twice. Results revealed that the use of supplementary lighting using LED fixtures had influenced selected species under Crassulaceae. The use of three hours supplementary lighting under low light intensity had statistically similar results with those of the control S. letizia, C. rupestris and G. opalina in particular parameters. Meanwhile, succulents under six-hour with high intensity condition grew well, compared to species S. letizia, C. rupestris and E. ‘Momotaro,’ demonstrating that the data was significantly different. Interestingly, there were no statistical significant differences between species C. rupestris and the control regardless of change of variables (duration and intensity) in all parameters.
