bloody brilliant, guys like that bending the way we think things work, ferkin love it, reminds me of a weed grower on the net who challenged all stereotypes on how things should be done, and did it better than anyone else (also using lots of small plants instead of a few big ones to create higher yields)
which leads me to believe that this approach should work with any plants, small plants, relatively low yield per plant, but planted so densely that the yield per m^2 rises exponentially
great vid!
