Raising leopard gecko humidity?

You should be ok nothing is going to happen right off the bat. He could develop mouth rote I'f it's high for too long(talking weeks) The humidity should go down on it's own just monitor it for some time don't put the humid hide back in there until he starts to shed and take it out when he's done. Make sure his water bowl isn't under the heat lamp if you have one or heating pad that should help too
