PURPOSE: A plant cultivation system is provided to reduce the plant cultivation time by controlling LEDs and the injection rate of photosynthesis stimulation liquid to be sprayed on the plant within a housing. CONSTITUTION: Plants to be cultivated are planted within a housing(1). A variable LED module(2) is possible to control the wavelength and illumination of emitting light. A light controller(3) controls the wavelength, illumination, and wave of the light which the variable LED irradiates. An external sensor unit(4) detects the intensity and temperature of sunlight outside the housing. An internal sensor unit(5) detects the temperature and illumination inside the housing. A storage tank(6) stores photosynthesis stimulation liquid containing titanium compound. A feeder(7) comprises a feeding nozzle(7a) supplying the photosynthesis stimulation liquid to the housing, and a pump(7b) supplying the photosynthesis stimulation liquid from the storage tank to the feeling nozzle. A controller(8) controls data, and the operation of the light controller and the pump. A power supply device(9) supplies power source to the controller. Data are received from the external and internal sensor units. The titanium compound includes any one among titanium dioxide, titanium tetra-chloride, and titanium tetra-isopropoxide. The power supply device a commercial power supply system. The power supply device is a battery which is recharged by a commercial power supply system. |
