okay, I put another thermometer in there, they have the same reading on the cool-side, both hitting about 80 degrees F. I replaced the 65w with the 100w because I saw a massive drop in temp on the cool side. (about 67 degrees on cool side with the 65w bulb). I put the thermometer on the hot side, getting about 90+ degrees. I think a 85w bulb would probably hit the spot... I currently dont have any money (Im not an adult) for a thermostat.
EDIT: the Basking-side got to 93 degrees F when writing!!! Yeah, Im going to get a 85w A.S.A.P.
