sorry didn't mean blow! i was typing too fast meant bowl. form now on referring to it as WATER DISH lol.heres basically how i would go about the day with the tank. i would turn my rooms light on at dawn and then the heat lamp. when the sun went down, off go the main lights and heat lamp. the temp stayed above 65-69 at nights, never got above 80 during the day. for winter im going to get that under heater. i never covered the tank, just read that it can help combat the over head lamp dehydrating the tank. wont do it now that you guys confirmed by findings that they really don't need a constant high end humidity.
