Urban - I already have two 150watt Hydro grow-lights that were donated. I was going to use those, but I think the fluorescent will actually illuminate a greater area. So I will probably use them instead... That way, the really nice Hydro lights can find their way into the riverbed system that I am designing for my garage!

Thankfully this system is located in my school, so electric costs are of a lesser concern right now. When I set up my home system - that will be a different situation.

JCO -- thanks for the kudos, my friend. I am simply doing what I can to teach what I can to my students. Hopefully they will get something out of it...
