Get the humidifier that came with it out of there. Get the sponge out. With just the 65% bovedas in there, where is the RH sitting at? If it's at 65%, then you are golden. If it is dropping lower or the bovedas are drying out quickly, you have an air leak somewhere, or as Kayla suggested, you might have very dry sticks.

I gave up on my desktop and have kept mine in tupperdors until I finish my winedor.
