Thanks for the info. When you say pack pretty tight what does that mean as far as distance center to center? What wattage do you use? The 100W equivalent are pretty inexpensive in bulk.
I'm thinking 6 CFLs for the 2' x 4' shelves. Which should be <$20 per shelf incl. the bulbs
I'm not too worried about matching the full photosyntheic spectrum since it is for short term seedling growth, but the curves are interesting. Your PAR curve doesn't match what I remember for photosynthesis rate, or am I misunderstanding what you are showing?
