Everything I've read said that supercropping was gently crushing stems and rolling them in your fingers, with the hope that it will repair itself bigger and better, thus allowing nutrients to flow more freely. It never made much sense to me, since flow rate is determined by the smallest opening of a run (in this case the run is a stem). Unless you crush and roll the entire stem, and continue to do that as it grows, nutrients are still going to flow at the rate of the smallest part of the stem.

Also I thought that was a stupid name for it. Now stinky says it's something other than that,and the name makes much more sense, so I'm going to have to reconsider.
