Jbog,
I suggest doing a little more homework on your subject. Just throwing out the question in a forum will get you some information, but what you want is definitive information. I suggest searching at other forums, but especially look for those who have had extensive experience and success at propagating from seed.

In fact, Brent's site has some of the best, most precise information about all aspects of propagation for bonsai. It's how he makes his living. You can't get much better information.
