I think your title is misleading. Everyone has a different definition of "potential". The author seemed to concentrate
on defining the most efficient way to grow as much in a defined area as possible. I'm sure that question is of great importance to
those with strictly commercial interest in growing. The old, large plant that scores well on the authors' chart is not what I've got going
in any of my 3 rooms. I'm more concerned about exploring with each new variety, trying new ways to grow them and see what happens.
I think most here are closer to me and my philosophy than commercial "growers".
Just my opinion, BigSteve.
