CB, I remember seeing that study saying diffused light is more effective but it was referring to greenhouse where light in "free". But indoors I suspect intensity comes first because if we tried to diffuse the light, intensity would decrease very significantly.
We can get some of the diffused effect by having overlap from several COBs running soft and maybe by having a slight breeze in the canopy to move things around. Another way to put it, if the undiffused light gets me me gpw, then I would give priority to intensity and we spread it as evenly as we can.
