You can get flourescents that screw in to a regular lamp. That's what I'm using, and my babies are as green as ever. I recommend a very small lamp that you can orient in any direction to get as much light as possible. I'm only using one light at this point (42 watts, says it looks like 200 watts iridescent); I think it's cool-white. These flourescent "bulbs" are not recommended to be "hung" upside down in a "hovering" or desk lamp due to fire hazard (read on the packaging). Also, I'm giving my plants sunlight as much as possible, but that'll change soon since they'll be visible from my balcony. They're really shooting up! This is my first grow, and I have to say, all the advice I've gotten on forums and websites and such has been WAY useful.
