Discussion on the Effect of LED Light on Cannabinoid Accumulation and the Design of Artificial Lighting System for Hemp (Cannabis Sativa L.) Cultivation

LED has been applied in the field of cannabis cultivation due to its high efficiency, energy saving and controllable spectrum. This article introduces the botanical characteristics of cannabis, the cannabinoids and the classification and application of cannabis. Through the analysis of relevant research at home and abroad, it focuses on the effects of photon flux density (PPFD), light quality, and photoperiod on the growth and development of cannabis and cannabinoid accumulation, then puts forward relevant suggestions and considerations. Finally, the design of LED artificial lighting system is discussed.
