Your substrate doesn't look very wet, and the analog thermometer/hygrometers are useless. You need to pick up an accurite temp/hygrometer from Walmart to get accurate readings. I have used the reptibator and the hygrometer and thermometer don't work that well. How did you determine the water to substrate ratio? I would recommend going substrateless (search this forum for detailed explanation).
