I don't know much about the cfl's for plants, but I sure hate them for house lighting!
I think from what I've read, you have to use a lot of them to achieve adequate lighting for plants. And most sold for plants seem to be the bigger, higher intensity ones than what you find in Kroger.

Rick, it seems your best option might be cheap shelves and shop lights. Just hang from s hooks and chains, and it's easy to adjust the height as plants grow.
You can find cheap shelving @ Home Depot or Lowes. Then you can either use shop lights, or lots of other options. Hydroponic stores tend to have every possible kind of plant lighting, though most are more pricey than shop lights.
