Come to think of it, the guy I got my clones from had a T44 about 4 foot tall. It was looking rather spindly and not much foliage, but it was quite branchy.
Whether it was that way because he wasn't taking good care of it or not, I don't know. He had it under a 400W HID, but his temps were around 33C.
He said himself that he knew it was too tall and he was just experimenting and mucking around with it.
