Frequently Asked Questions
What are photoperiod cannabis seeds?
Photoperiod seeds produce plants that flower based on light exposure. When the light cycle is reduced to 12 hours on/12 hours off, the plant transitions from vegetative growth to flowering. This gives growers precise control over plant size and harvest timing.
