A plant cultivation apparatus includes at least one housing, a lamp holder mounted on an upper end of the housing, a basin mounted on a lower end of the housing and containing soil, a light emitting diode (LED) lamp mounted on the lamp holder, a water pipe connected with the housing to supply water to the soil of the basin, a constant rate timing device connected with the water pipe, an external water source connected with the water pipe, and a high oxygen water generating device connected with the water pipe. Thus, the plant cultivation apparatus can enhance the growth efficiency of the plant by provision of the high oxygen water generating device. In addition, the plant cultivation apparatus has sterilizing and odorizing functions by provision of the ozone generating device.
