This is why many North American growers are turning to feminized seeds—cannabis seeds that carry only female genetics, and can be relied on to produce only female plants. By creatively applying technologies to seed feminization, modern breeders like Kannabia can ensure female genetics in seeds with a nearly 100% success rate.
This change occurs when the photoperiod, or amount of light and dark that the plant receives, changes to 12 hours of light and 12 hours of dark. In outdoor gardens this change can happen naturally with the seasons or, in more controlled environments like indoor gardens, by human intervention using light timers.
Male vs. Female Cannabis Plants
Once those plants are old enough, growers have to go to the trouble of actually determining their sex, monitoring each individual plant to ensure any males are removed before they can pollinate their female counterparts.
Traditionally, the solution to this has been an inelegant one, with many cultivators planting at least twice as many seeds as they hope to harvest with the assumption that about half of them will be useless. However big a harvest you’re looking for, using regular seeds means you’ll have to plant twice that many seeds.

Feminized cannabis seeds are important to cannabis cultivation because only female plants produce consumable flowers.
Autoflowering seeds have been bred to move into the flowering phase without needing changes in light to activate the production of flowers. Whether cannabis seeds are seeds doesn’t have anything to do with when plants enter the flowering phase. Feminized cannabis seeds have been bred to grow only female plants.
Theoretically, plants sprouted from feminized seeds should not produce seeds. They should only grow into female plants, and unpollinated female plants produce buds instead of seeds. Cannabis plants make seeds when the flowers of a female plant are pollinated with the pollen from a male plant. In the absence of male plants, there should be no pollen and therefore no seed production. If you force a female plant to stay in the flowering stage too long, however, all bets are off and you could wind up with rodelization as discussed above.
Breeders and growers developed feminized cannabis seeds to address these challenges. By increasing the likelihood that all your seeds will produce female plants, you eliminate the possibility of getting a male plant that won’t produce flowers and of having a male plant accidentally pollinate flower-bearing female plants.
