Scrog is a method to develop an even canopy... For me it's a major pain in the ass... I can manage my canopy with supercropping just fine.
Amen to that! That's one of the problems with doing a ScrOG in Bubbleponics...the suckers grow so fast you can't keep up with them!
I personally believe you almost have to do some form of training to maximize the light in low light-intensity situations (i.e. CFL's or 250 - 400 watt HID).
ScrOG is probably the most time-consuming method but gives the best results if done properly, IMO. I love supercropping and use it even when I ScrOG. LST is my least favorite method, I usually end up with string and fishing weights all over the place and manage to snap quite a few branches along the way.
