Yes, you are wrong. Where did you read that?

Hermie seeds have a 50% chance of being hermie and more chance being male.

You cannot make femanized seeds at home. It's like a massive selctioin thing and some genes get taken out or something like that. I have no idea, if you wanna know google it and that'll give you the answer, but no, hermie's dont produce femanized seeds.
You are probably right Lip. I think i readed about it in this forum.
I am new so.......don't realy recognise my own plants.
