mmk, since i'm readin on this plant light spectrum junk, i also realized i need to kno the plants function.. (been focusin too much on the lighting) but anyhow I read up here about how the underside of the leaves is the site of photosynthesis . and given what we kno about the 420nm, can't we get say 2 of those specific tube fluros and blast'm upward toward the underside of the leaves?? that might hit the spot for the photosynthesis, no??
