hey i was having an issue awhile back with temps that were too low and finally realized it was due to the heat pad not being powerful enough (wattage was too low). i ended up with another heat pad with a little bit of a higher wattage and it made a difference. i also stopped stressing out that i wasnt getting exact temps and just settled for the good temp ranges and things are fine here. my snake is eating good, shedding good and thermo-regulating like she should so apparently things are ok.
