Agreed, it *is* stupid, assuming that one is trying to cultivate homegrown
ditch-weed.  By the same token, the theoretical question itself is

I seem to recall that most plants absorbed best in the 420-460 nm range...
and slightly less so in the 650-680 nm.  Off the subject of what colour
bulb to play on a cannabis plant, but out of curiosity....I'm assuming
that those absoption spectrum numbers are based on chloroplasts.  Does
anyone know if accessory pigments play a large role in this?  Is there
a noticable difference in absorption in a plant that is high in, say
anthocyanins or phycoerythrin?  Do they operate in the same manner as a
plant which lacks these pigments?

Note to any drug enforcement agencies reading:  The nastiest thing I've
got growing in *my* backyard is crab-grass.  Feel free to come and 
confiscate it. :)
