In step S502, the planting unit is carried by the conveying device, and then in step S504, the control unit obtains the growing range of the planting unit and the illumination range of the lighting module by the detecting unit. In step S506, the control unit determines the distance between the illumination module and the plant according to the obtained growth range and the size of the illumination range. For example, as shown in FIG. 2A-2B, the control unit adjusts the illumination mode by the position adjustment device 210. The distance between the group 206 and the plant planting unit 208, when the growth range of the plant is larger than the illumination range, proceeds to step S508. Otherwise, when the growth range of the plant is smaller than the illumination range, step S510 is continued.
