My new BP was just delivered and I'm having some high humidity issues (99%). I added some moist reptichip a couple days ago along w/ some artificial plans and my Hygrometer went to 99%. I left the door open for over a day, took the substrate out and wiped down the enclosure. This morning I put back the substrate (was a little damp but not wet) and the Hygrometer went back to 99%. Is this a huge concern and what should I do? Should I reinstall a dry bed of reptichip?

It's a pvc enclosure w/ 4-5 slats on each end for ventilation.
