So if a guy was at least gonna breed to make some of his own beans, is it better to breed an IBL or TBL to each/or; or do you want one stable side and one hybrid side for variety, or do ya just do hybrids and get what ya get, and do you lose potency breeding like that say up to f4 or f5, just as an example?! In laymans terms, what is the basic beginning theory or principle idea of it? Ive got the breeders bible, and read it, but before I start worrying bout color of leaves and width, and shape and such, I want to make sure of the basic theory. And can't you cross anything, or do you need some even if few of the same characteristics?!, damn book got me befuddled at times..................... thanks for any feedback, especially you Subsir, dude.
