One of the most important growth factors in cannabis cultivation is light which plays a big role its successful growth. However, understanding that how controls industrial hemp and development poor needs advanced research. Therefore, pot study was conducted to investigate effects different colors light, is, white (WL), blue (BL), red (RL), 50% with mix (RBL) on morphology, gaseous exchange antioxidant capacity hemp. Compared WL, BL significantly increase terms shoot fresh biomass (15.1%), dry (27.0%), number leaves per plant (13.7%), stem diameter (10.2%), root length (6.8%) chlorophyll content (7.4%). In addition, promoted net photosynthesis, stomatal conductance, transpiration, while reduces lipid peroxidation superoxide dismutase peroxidase activities. RL RBL reduced biomass, gas parameters enhanced enzymes Thus, useful for large-scale sustainable production
