The goal of this study is to investigate the effect of light intensity, water recirculating system and nutrient concentration on the growth of Chinese cabbage in an aquaponic system. The hardware architecture is designed based on the hydroponic cultivation technique which is applied in the aquaponics system of three irrigation water recirculating systems, including water cycle, overflow and ebb-and-flow systems. Moreover, white-light-emitting diodes are used to replace natural light. The results show that the light intensity has to be greater than 210 µmole・m-2・s-1. Furthermore, increasing the density of guppy or mixed the different type of fish’s waste can effectively enhance 20% growth of Chinese cabbage.
