Cannabis can be male or female, and males fertilize females in the wild, which subsequently produce seeds. The genetics of both male and female plants are passed down to the seeds, so when a female plant dies—cannabis is an annual plant that grows and dies each year—it drops seeds, which develop into new plants the next spring.
Because only female cannabis plants produce buds, when pollinated, seeds develop with the buds. Sinsemilla, or “seedless” cannabis, was developed to prevent seeds out of female plants, allowing them to produce just buds. Male plants are discarded or relocated away from females before they produce pollen sacs and may fertilize females when growing sinsemilla cannabis.
The Advantages of Sinsemilla
There was a significant possibility that the cannabis you cultivated or bought had seeds in the buds before sinsemilla became a regular practice among farmers. Bud containing seeds is typically regarded as inferior quality—seeds provide a harsh smoke.
With sinsemilla, the cannabis plant may focus all of its energy and resources on making buds rather than seeds. This results in superior quality and potency buds, as well as larger yields because there are no seeds in the buds. The strength difference is so stark that when customers first began smoking sinsemilla, they mistook it for a separate species of cannabis.
