I don't think admins are going to shut it down right now, because you really do need a thermostat. No egos or anything aside, it's just a required piece of equipment in snake keeping in particular, since their temp requirements are relatively low compared to other species. =) It's kind of like getting hay if you want to own a rabbit LOL.
You are obviously trying your best to have the best setup possible. Just need to look more into it that thermostats are part of snake keeping!
