I wish I had the link so I could hook you up with it, but, I saw a gentlemen veg his plant out in a flat space to achieive a certain heighth. Once they reached that heighth, then set the bulb hanging vetically. After that, he simply just set his plant in a circle around the buble. Bada bing bada boom! lol. I don't think you would really have to change anything beside the piece that holds your light. But then again, if it ain't broke, don't fix it. You obviously are already doing well in what your doing, so no need to figure out how to setup a vertical unless you like to experiment. Anyhow, keep up the good work man.
