Photoperiod feminized seeds require a controlled light cycle to transition from the vegetative stage to flowering. These seeds are specifically bred to ensure nearly 100% female plants, eliminating the need to identify and remove males from a grow.

Understanding XX and XY Chromosomes in Cannabis

In cannabis genetics, sex is determined by chromosomes:

• XX Chromosomes → Female plants (produce buds)
• XY Chromosomes → Male plants (produce pollen, not buds)

Feminized seeds are specifically bred to have only XX chromosomes, ensuring reliable female plants. This is achieved using a proven, one-time chemical application spray to induce pollen production on select female plants. Since these pollen-producing females lack male (XY) chromosomes, their offspring inherit only female (XX) genetics, resulting in feminized seeds.

Additionally, carefully selected hybrid or pure legacy strains are used in breeding to further reduce the risk of hermaphroditism, ensuring stable, high-quality genetics for growers.
