It's a bioactive enclosure, so going to something sterile would mean moving him to a rub... Not sure if this would be appropriate?

I have a humidity sensor right in the middle (put in after taking this photo) it's at ground height and leo spends about half his time under Cork bark and half basking up high so it's possible that it's less humid up high I guess.

I can't figure out what's caused the problem... Unless he's been claiming over the lights (Jungle dawn LEDs) and their fittings perhaps.
