I live in South East Iowa, and it gets COLD in the winter. I have an 8x3 tortoise table, that will be in my room. (Upstairs) It is pretty cold in my house during the winter. We keep the house at 65°F. It feels slightly colder. I also have a humidifier if need be. What kind of tort (preferably a Redfoot, Yellowfoot, Cherryhead, W. Hermanns, and a Russian) would be best for me? Also I'm a complete newbie. I'd Prefer not to spend a lot on heating/lighting. (I'm 14 and saving for a car lol) TIA!!!!
