I'm getting 2 new snakes in a week or so and will be QT'ing them in tubs. I'm pretty sure I want to use a herpstat, but herein lies the question. I'll most likely use this t'stat for a rack when I get one and would rather have as few t'stats as possible. So would I be better off getting 1 regular herpstat if the tubs I'm heating are the same size with the same size flexwatt in the same shelf of a shelving unit or a herpstat II?
