Meh, I guess you haven't seen the threads where I've discouraged [that's putting it nicely] people from just randomly tossing seeds all over the place if they don't intend to return and kill the males. Because I would be RIPSHIT if Clem let his studs into my stable.

I pretty much expect a certain [very small] number of seeds in outdoor bud... doesn't worry me a bit... it's not going to be the same sort of catastrophic event as an indoor disaster!!!

Edit: I sorta interpreted the original post as asking about pollenation across species lines.
