Frank,
I've had a handful break out of dormancy early. I keep them in a very cool part of my basement, but I don't think it is quite cold enough. (Plus there's a window nearby, and I think maybe the light gets them all excited.
So far this year I'm just putting them in front of south facing windows, and things seem to be working out OK. I'm watering them but not fertilizing them. They're growing slowly and nicely, not getting leggy at all.
Last year I had a couple do the same thing, and I put them under the fluorescent grow lights I was using with the cuttings. They did well, too. On one tree I got figs early, as if the tree was forced. (...which I guess it was, albeit unintentionally.)
