its a real pain to keep the humidity level high because i live in the desert with basically 0% humidity all year long. i have a towel on top of the tank that i keep soaked along with my heat lamp above the water dish. the little pos hygrometer i got says its 65% right now, but i dont know how accurate that is, i figure as long as its above 60% it should be fine. i ordered a little humidifier off of ebay but it still hasnt arrived, its coming from hong kong.
