The great thing about paper towels/paper is that they can use it as a hide and go from hot to cool side while under the paper lol. I wouldn't hesitate to house her in the 12q with one hide, water dish and paper substrate if you think it would suit your needs better. (assuming the 12q is the type that is about 6inches tall). That size would work for many months, and after she gets larger u can always remove the single hide to give her more room to move and stretch. 32q maybe when she is about 900-1000grams. Good luck with whichever u decide!
