This study, an experiment was carried out by planting Hydroponic culture. Three types of lettuces include green oak, red oak and filley. The aims of study were to develop a hydroponic vegetable planting kit using electronically controlled artificial lighting and to study the growth of vegetables grown in artificial light 8 hours/day It has developed five types of artificial light with wavelength and intensity for use with two growing systems, namely the wicking system and the deep root floating technique (DRFT). The wavelength 580 nm and RGB LED Strip light with 9 watts of power were suitable for growing green oak, red oak and filley seedlings during the first 7-14 days of cultivation. This condition was suitable for lettuces growing until harvesting period. Natural light must be used in conjunction with artificial light by a series of grow B2, which has a wavelength of 580 nm, a 63 watt RGB L + White LED, placed outside the building and can be used with both the widling system and the water circulation system (Deep Root floating Technique DRFT).Red oak and filley in DRFT condition, the weight and the number of leaves is higher than only natural light. However, the red oak show not clearly the red leaves. The cost of the lighting system used to produce lettuces in the circulating water system is 21.40 baht per plant, which is very high, so it might be used only during insufficient light and used in conjunction with an environmental meter that measures light intensity. It used for solution temperature and the surface temperature of the planting set in real time to reduce the cost of lighting and to adjust the environment in the plantation to suit for vegetables growing,
