Breeders offer cannabis genetics in several forms, each suited to different goals. Regular sativa cannabis seeds produce roughly equal numbers of male and female plants, which makes them useful for anyone interested in creating new crosses. Feminized versions are treated to yield almost exclusively female plants, saving space for growers who only want flowers rather than pollen. Autoflowering hybrids combine equatorial genetics with ruderalis traits so the plant blooms according to age instead of light cycles.
