High humidity forcing me to cut down on misting

My humidity reaches 85% after mist and drops to 75% at lowest.. this is obvious too high? I mist 3 times a day, and I have already cut down on the misting sort of.. I no longer spray for several minutes. I just spray like 10-15 times all around the plants making their leafs covered with drops.

Cage info:
Exo terra
3 live plants, 2 fake ones.
about 10 branches.
no substrate.
5.0 uvb bulb, 2.0 daylight bulb, 100w basking bulb (only turns on for 2 hours at day).

cham info:
veiled female. 2 months old.
eating pretty good from bowl.
drinking: not sure. never seen her drink and there have been a tiny bit of yellow in the urine.

But I dont want my cham to go dehydrated.. Kind of a dilema.
What should I do?

Use a drip system drinking water about 20-30 minutes a day and then you can cut back on your misting some.

One thing you can do is leave the basking bulb on longer. (I would use less than a 100 watt, more like a 60.) What are the temps at the basking area? With a young female, I'd try to keep the temp a bit lower, but I would suggest having the option of basking for longer periods during the day. It will help with digestion and self-regulating her body temperature. Additionally, it will aid in "drying" out the enclosure a bit by adding to the evaporation. Hope this gives you some ideas.

I do use a dripper. But I dont think it is doing any good. Never seen her going near the "splash" area. IM not sure I have placed the dripper correctly. It do drip on a bounch of leafs before landing in the container on ground, is this good? Or should she be able to go stright to the tube and drink there?

basking temp is about 80-85 F

Yeah, like Decadancin said, I'd change to a lower wattage basking light & keep it on longer. I have mine on 12 hours a day (I'm from the uk, so I need to keep it on as it's not as warm as the us )

Also I don't think the viv itself will be helping. Ventilation will be a big help in letting the humidity spike & drop to a better level. If you're able to, I'd try to set up some cheap computer fans to gently blow in & extract air out through the small vents at the front of the viv if you're unable to use a mesh door

Hope that helps you somewhat Sorry if it doesn't
