The facility is used for pesticide-free cultivation, and includes a crop cultivation house which is formed of a light transmissive material and in which crops are cultivated, and a lighting control unit that controls the light to be irradiated upon the crops in the crop cultivation house. The lighting control unit is adapted to control spectral radiance (Bi) of a wavelength range of blue light, spectral radiance (Ri) of a wavelength range of red light, and spectral radiance (FRi) of a wavelength range of far-red light among the light to be irradiated on the crops that are cultivated in the crop cultivation house so as to be a predetermined condition.
