lots of fluorescent light doing nothing

[Meredith]

Ron...I am growing one tomato plant in a MicroFarm inside. It's very happy right now, with bright green leaves and a ton of leaf growth happening on top. The problem is, I am using lots of fluorescent light and I keep reading here that that won't do it when the plant gets bigger. It's about a foot tall right now. At what point do you think I'll HAVE to shell out big bucks for better lighting? Thanks, Meredith
