Very good thread, very informative! I'm gonna have to master this technique while I am still stuck with small grows indoors. Turns out I'm gonna have to wait to get an armoire to start the trainwreck cross. Oh well, it's not that far off..
Sorry, I got a bit off-topic, one thing that I can add to this, is that if you do snap a stem or branch, honey(organic) is an excellent salve. It helps bond the stem together as well as helping to heal the break. I can't remember which book I read that in, but it works like a charm.
