That's an interesting read Ben, thanks for sharing.
I think the general rule for 10 gallons in my experience should be 30-40 watts of CF light over a 10 gallon to grow almost anything. For NO bulbs it should be on the upper end of the scale since I never got great results running them with only 20-30 watts.
I used a 36 watt AH kit over a 10. More than enough light to grow anything. CO2 and ferts must be adequately dosed or algae will occur. I'm currently running pressurized CO2 with it, and still have some algae issues that I'm resolving.
I also used (2) 25 watt screw-in CF bulbs from lights of america. No algae issues, and ran with DIY CO2. Plants grew well. Only complaint was the weaker spread of light in the center. This led to faster growth on the sides and slower growing in the center. Definately not a bad choice for those on DIY CO2, and looking to keep maintainence low and cheap.
