Photoperiodic varieties: 18/6 or 24/0 vegetative, 12/12 flowering induction. Autoflower: Constant 20/4 or 18/6 for maximum yield. Avoid light interruption during the dark phase - even 1 lux can disrupt flowering. Timer precision important: ±15 minutes tolerance. Moon phase influence not scientifically proven.
