well... the fem seeds can get a pronoun expansion in a whim or from you doing and trying to learn 1000s of things half way, or you could cut some of that by sticking to one strain. there is enough differences within one strain to have ones hands full.
i understand all that say "i always did whatever", but if you didnt have to... you can argue that it can and is done, but for best results and best practice eliminate some variables.
the regular seeds i will assume are bag seed? some will tell you all about how bag seed are fine... but for the beginner... and for the industry... not so much.
think about how the bag seed must have gotten there. some plant hermied and spread its hermie nature to some other plant and now you have a genetic tie to the potential to hermie. you, with much work and some good patience and maybe some lab help, could make something worthwhile from it. but as a newbie, what mostly happens is pollen sacs pop and you see some powdery stuff and wonder whats up. then for every plant there are seeds...
but you will dive however headlong you would dive no matter what. so keep notes, a spreadsheet is good, and note everything. watch, wait and watch more. hope you have fun!
