This study was carried out to determine the optimum EC supply by accumulation amount of solar radiation in closed system. EC concentration of drainage was higher than that of supply. The higher EC concentration of supply was, the lower pH of drainage was. It was no difference in the quality of cut rose 'Nobles' (Rosa hybrida), stem length, stem diameter, leaf number, petal length, and petal diameter by EC treatment by season. The yield was higher about $6%$ in treatment of EC $1.3dS{cdot}m^{-1}$ in April and May, about $10%$ in treatment of EC $10dS{cdot}m^{-1}$ in June, July and August, and about $10%$ in treatment of EC 1.0 or $1.3dS{cdot}m^{-1}$ in September and October than the others. In general, the yield of the cut rose was higher in treatment of (B) EC 1.3 mS/cm in spring, EC $1.0dS{cdot}m^{-1}$ in summer, EC $1.3dS{cdot}m^{-1}$ in autumn, and EC$1.6dS{cdot}m^{-1}$ in winter.
