It is still holding at 70% today from saturday afternoon when I closed up the vents with acrylic. I will probably pick up another hygrometer just in case this one is off. It is definitely humid and I have only had perfect sheds from her so far (before the changes). I just don't want to overdo the humidity. I will be on the hunt for a decent hygrometer now. I am using a digital one inside the cage but my first digital thermometer was off by 10 degrees so I don't trust just one.
