Yeah...your temps are good now John. When she shows signs of shedding, start misting her plants a bit a few times each day. That will get the humidity back up for shed time. It's okay where it is now. If you want, you could mist once or twice a day just to increase it a bit. I'm always trying to keep mine up...so I keep a spray bottle by the tanks and mist the plants a couple times a day. You just don't want it too moist in the tank...stick to misting the plants lightly, that's what I do...you don't want moist substrate.
