That's exactly the thing amnesiac... thankyou for taking the time to post your thoughts as it has hit upon something important. I remember reading that blue has the slight edge on potency while red has the slight edge on yield. Slight edge? Who decided that?

It seems to me that if the blue photons are richer than the red ones, then providing a rich blue light source would benefit the plants more than providing a rich red one does.
