The problem is that most people increase humidity by adding water via spritzing and other methods which do little in the way of anything therapeutical and instead only satisfy the reading on the humidity gauge.
When you add this stagnant water to a tupperware tub with a few sparse holes burned in it for airflow, all you do is turn the enclosure in a petri dish. If you really think increasing humidity is of benefit, then create a humid hide with thoroughly wrung out spaghnum moss.
Correct me if I'm wrong Nikki, but aren't you a veterinary student at one of the foremost veterinary colleges in North America? Maybe this would explain why your advice in this thread was spot on............
