Michael is right. You want to keep the humidity up but not the enclosure moist. You will want to let his enclosure dry out between mistings but keep the humidity up. With a humidifier you shouldnt need to mist as often because the water droplets will stay on the leaves longer creating a longer drinking op. A dripper is good too for not getting the whole enclosure wet. It will give him a spot to drink from without making the whole enclosure wet. I just use plastic cups with a hole poked in the bottom. It might take a couple times to get the hole the right size so it doesnt drip to much or too less. You can use 1 liter bottles, gallon jugs etc. Use a drip catcher to catch most of the drops as they get to the bottom of the enclosure so it doesnt make a mess. It can take some playing with to get right.
