Fem. seeds come from hermie plants that self pollinate themselves. Thus the term but the big debate is do most these seeds also go hermie easier. I have always had good luck with them but I am real anal about how I begin and germinate them more than most on here. Last grow I had 100% germination and out of 8 I had one male. Love that rate. Even if you get fem. seeds your still have a likely hood of a few being male.
