when to upsize

Well, I bought my first BP Saturday at the North Ga Reptile Expo (and I did see the BP.net booth) from Hippie Herps. She is really beautiful and in great shape.

My question is when does one upsize the enclosure? Right now she is in a 16QT tub that measures about 13" x 9" and she is definitely longer than the long side of the tub and is rather active one the lights go out.

i would say that size is good up to about 200-250g body weight. Many people start hatchlings in a 16x11 rubbermaid 2220.
