Dear Dan, Will you please explain the difference between auto-flowering, feminized and normal seeds? - Tim P.
Normal seeds are just that – normal. Meaning that normal seeds are the result of male pollen landing on a female flower and producing seeds that can be male or female. Feminized seeds are the result of using “male” pollen from a hermaphroditic plant to fertilize a female flower, resulting in plants that can be female or hermaphrodites but never males. Auto-flowering plants are plants that begin the blooming process at a certain height rather than by any changes in photoperiod, meaning that auto-flowering plants will begin flowering regardless of whether they get 12 hours of light per day or 20.
