Hopefully as time passes, more growers will post here, as the only real way to learn directly from folks who've tried it, experience beats 'book learnin' any day.

Oh, sorry, and I don't mean to contradict you, bonbon, just adding my take on it (I'm in a bit of a bolshy mood, so I've probably forgotten my socail graces)
tell me more about this forming 2 colas thing. it sounds like it mihgt work for me. PAZ
