Determining the optimal light schedule for cannabis is key to successful cultivation. At California Lightworks, we suggest an 18/6 (18 hours light, 6 hours dark) schedule for the vegetative stage to promote vigorous growth, and a 12/12 schedule to trigger flowering. Some strains and conditions may benefit from variations like 20/4 or 14/10. Tailor your light schedule to the strain’s needs, growth stage, and environment. Our LED grow lights provide the flexibility and precision needed for optimal cannabis cultivation.
