Good info on the growth, but I'm going to have to disagree with you on the hide box issue. I've heard of some breeders who don't use hides, but they were keeping the animals in a room set aside just for the snakes (i.e. not much foot traffic or people around), and in fairly short, dark enclosures. Fact of the matter is, these are not social animals, and they need somewhere to retreat from time to time, especially right after a meal or while in shed.
I see this question from time to time on the board, and it makes me wonder, why not have a hide box? At least for me, they're the cheapest part of my setup: I just get a ceramic flower pot and cut a hole in the side. Do you want to have the animal always visible? If that's the case, you may want to look at a different pet, since snakes in general don't want to pay attention to you or be visible all the time.
Give the snake a hide, and you'll have a healthy animal who is, at least some of the time, out in the open for you to enjoy viewing. Don't give the snake a hide, and you'll get to see it all the time, but it'll be stressed out and possibly sick or snappy as a result.
