Photoperiod cannabis seeds are genetic variants of the cannabis plant that rely on changes in light cycles to trigger flowering. These seeds require specific light schedules, typically 12 hours of darkness, to transition from the vegetative stage to the flowering stage, making them popular among experienced growers for precise control over growth and harvest times.

Regular cannabis seeds are the original, unaltered genetic form of marijuana seeds. They can produce both male and female plants, offering breeders the opportunity to create unique strains through natural pollination. These seeds are favored by experienced growers seeking genetic diversity and traditional breeding techniques.
