use a larger water bowl or more than one bowl, put the bowl over the heating pad, make the diy humid hide and/or humidifier, place a damp towel over the top of the enclosure, don't use a bulb for heat--use a heating pad, put a humidifier in the room to get the overall humidity up, make sure you are measuring your humidity with a digital hygrometer like the accurite and not with an analog one because the analog one may be giving you an incorrect reading.
