What type of enclosure are you using. I use an aquarium we added a very large water dish and covered 3/4 of the top with a peice of Plexi from HD. Drilled a few holes for ventilation now our humidity stay at 55-60% easily with a spritz a couple times a day up to 70-75% no problem. See the photo below this was our first version we added some foil tape to it later to stabilize the temps that also worked great.
