99Stang,
I have not bred my own seeds yet but have also done a lot of researching for future science experiments. I did find an article on a different form dedicate to Autoflowers... " autoflower.net ".
I have a female auto that I am spraying with STS to reverse her. Then, I will use her/his pollen to pollinate another female and as best I have read.... all my seeds will be feminized autos.
I am also going to let her/him pollinate herself. Again, as best I have read, all the seeds will be fem/auto.
