Aren't we trying to make our plants light limited?  We add a lot of 
light, then add enough fertilizers, including CO2,  so that there is 
more than the plants will use.  If we increase the light, we also 
increase the fertilizers to stay ahead.  Anyway, that's how I have it 
figured out, but I do tend to be wrong a lot.
