Survival (A) and regrowth (B) of Cannabis sativa Cultivar 1 explants plated on MS basal recovery media and incubated in various times of darkness before exposure to low and ambient light conditions. Survival and recovery were analyzed separately. Bars displaying significant differences are denoted by different lower-case letters (p < 0.05). Light treatments: (1) darkness: 5 days, gradual light: 5 days, ambient light: 20 days; (2) darkness: 10 days, gradual light: 5 days, ambient light: 15 days; (3) darkness: 15 days, gradual light: 5 days, ambient light: 10 days; (4) darkness: 20 days, gradual light: 5 days, ambient light: 5 days; (5) darkness: 7 days, gradual light: 7 days, ambient light: 16 day; (6) darkness: 14 days, gradual light: 7 days, ambient light: 9 days; (7) darkness: 14 days, gradual light: 0 days, ambient light: 16 days; (8) darkness: 21 days, gradual light: 7 days, ambient light: 2 days.
