PURPOSE: A plant cultivation device for cultivating plant is provided to restore the irradiation of water and supply the water and nutrition solution by pre-programming according to the growth environment of the plants, and supply water and nutrition solution. CONSTITUTION: A plant cultivation device comprises MCU(Micro Control Unit)(100) which controls the supply of water and nutrition solution, irradiation of light according to the kinds of plants to cultivate； an order input unit(120) which inputs an operation order including the name of the plant to cultivate to the MCU； a red light source drive unit(130) which irradiates red light to cultivate plant by lighting red light； a blue light source drive unit(140) which irradiates blue light to cultivate plant by lighting blue light； a water supply pump drive unit(150) which supplies water to cultivate plant by operating water supply pump(152)； and a nutrition solution supply pump drive unit(160) which supplies nutrition solution to cultivate plant by operating nutrition supply pump(162). An order input unit comprises a key signal input part(122) which inputs several keys to the MCU by generating the operational order according to the selection control； a remote controller signal input unit(124) which inputs generated operation order to the MCU by performing communication with a remote controller and generating the operation order； and a communication unit(126) which inputs generated operating order to the MCU and generate the operation order by performing communication with an external computer. A plant cultivation device additionally comprises a memory(110) which supplies water and nutrition solution according to the kinds of plants to cultivate and restores the program which presets the time and period of irradiating the red and blue light.
