Abstract: A plant growth facilitating apparatus, for receiving and growing a plant, includes an accommodating body and a light emitting unit. The accommodating body defines an accommodating space for receiving the plant. The light emitting unit has a first LED set for emitting a red light in increasing the growth speed of the plant and a second LED set for emitting a blue light in promoting the photosynthesis of the plant. The wavelength range of the red light is 620-760 nanometer, and the wavelength range of the blue light is 360-480 nanometer. The light emitting unit is used for emitting light toward the accommodating space of the accommodating body, and the longest path of the light from the light emitting unit to the accommodating body is smaller than 1 meter.
