            Abstract : 
In this study, both a mercury free lamp and a conventional lamp were used for growing lettuce, which means that the R/FR environment was changed for one plant growth interval between R/FR>3.0 and R/FR<1.0. From the experiments, the growth speed was faster and the leaf shape and leaf area were larger than growing the lettuce under a single lamp.
