I would highly recommend a polypropylene tub for her hatchling to juvenile enclosure. They are inexpensive and easily turned into an ideal snake setup. Polypropylene is FDA approved, non-porous, and very easy to clean. Plastic also conducts heat far better than glass, thus you we have an easier time heating it and achievable what conventional wisdom would consider "ideal conditions". Walmart carries good Sterilite containers or you can look for IRIS tubs as well (Container Store almost always has these).
Once she gets larger (say 500+ g) you can move her to a more final enclosure, of which I would suggest either an animal plastics T8/T10 or a Constrictors NW PLM482314. I personally lean towards Constrictors NW as I prefer polyethylene to PVC, but that is up to you.
