Lilgreenthumb, just to clear things up for you a bit let me start by saying I just did what you are talking about by accidently herming two plants I polinated a third by putting it between them (and they themselves polinated themsevles too)... Now i'm no expert, but I read a lot, and people feel free to correct me if i'm wrong truth is more important then my opinion, but from what I read this method is not wanted for several reasons. First realize that when one parent hermies from stress it means it will have hermie to stress prone seedlings. This is why femenized seeds are frowned upon, they have the capability of eventually making all marijuana hermies due to major breeding within strains. When a legit company makes femenized seeds they stress the shit out of the plants and only the ones who DON'T hermie have clones from their mother treated with the collodial silver and then bred to cut waaaay down on the odds of hermies.
Now remember, I did the thing you are talking about, the seeded plants almost ready but not enough 100% mature seeds yet. strains I bred were a sativa (local blueberry tall skinny) and an indica (flying dutchmen blueberry skunk short fat) to learn more about genetics through my experience with the offspring (sure not 100% guarenteed to be perfect for learning but odds are still good and hands on experience is good for learning). I will not however ever let the seeds offspring ever be bred with no matter how good, because to be cannabis users (for medical purposes) we should respect it enough not to fuck up pots future for our future generations. A world where 99% of cannabis plants are seeded due to super high hermie rates is not a world I want to contribute to creating even if not in my lifetime.
