Regular Seeds: what can I do with the males?

Ok I understand that early as possible one should spot the male plants as they become mature enough in order to minimize the potential for polination of younger yet to be gender specified by multiple variables in the growth process. Is this simply because there is usually a lack of extra space and resources to have additional plants? If I can have plants in vegetative growth at a secondary location at which there can be cross polination given it's distance and complete isolation that ideally can facilitate breeding and seed bearing plants etc. then what are the hazards of doing so? Is there something else I should know about in regards to this proposed effort or my understanding of the purposes for the sexing of a garden and potential for additional breeding? Anything you all can share will be appreciated and if I'm waaaaaaaaaaay of base with my understanding here then, HELP!

If you want seeds, there is nothing wrong with pairing males and females together with a light breeze on them. Thats the easiest way. The downside is you will get a ton of seeds and not so much bud on your females. Another method is to just isolate the male until it starts dropping pollen. Then collect the pollen and use a tiny paint brush or q-tip to dab the pollen on several female budsites(rub the brush on the hairs) on one branch. This way you get lots of seeds and the rest of the plant is pure bud.
