The present disclosure provides a supplemental lighting method for vertical multi-layer cultivation of wrapper tobacco leaves, including the following steps: providing multi-layer vertical facilities, facilities including at least one cultivation rack having a plurality of layers; and providing supplemental lighting systems to each rack layer. For each rack layer the light intensity and light quality provided by the corresponding supplemental lighting system are set respectively according to a determined growth phase of the tobacco leaves during the cultivation process. The process includes cultivation of tobacco leaves through growth phases comprising a clumping period, a vigorous growth period, and a maturity period. During the clumping period, the light intensity provided comprises a first light intensity setting. During the vigorous growth period, the light intensity provided comprises a third light intensity setting. During the maturity period, the light intensity provided comprises a second light intensity setting.
