Ok. So with your new build you want to make sure not to block ventilation and keep the daytime humidity down. 30% humidity is perfect. I would limit the dripper to just about 15-20 minutes per day and instead mist or spray for at least 2 full minutes right before lights go on and off. The enclosure needs time to be able to dry out fully. You do need to remove and replace the artificial plants with safe live ones since our veileds like to nibble them. It only takes one bite for a serious bowel obstruction to happen. You can use the artificial plants attached to the outside to give your cutie more privacy. Live plants will add to and maintain humidity and provide little pockets of humidity where she can go if desired. Give her lots of branches and vines of varied diameters to travel and exercise. When she grows up and reaches her receptive phases, she will be endlessly wandering all of her branches in her futile search for a boy. Unless you are fully bioactive, remove the soil floor. Bioactive is a little bit intimidating to consider, but isn’t nearly as difficult as it sounds. If this is something that you are interested in, we can help you get it set up.
https://www.chameleonforums.com/blogs/intro-to-bio-activity.2429/ You need a better and more reliable humidity and temp gauge. The digital ones with the wired probe end are good and many people use the ‘smart’ ones, like Govee. To contain and maintain humidity and prevent your walls from moisture, like
@EmilioTheAnkify said, you can cover the back and/or sides with something, like a shower curtain, shrink to fit insulating window film, solid pvc or other panels, etc. You do not ever want to cover the top of the enclosure as that is going to reduce ventilation too much. It isn’t so much that high heat and humidity cause respiratory infections, but it is also poor air ventilation. The wild veileds who are living in south Florida are in a very humid area (basicallly is a swamp). They don’t have the RI problem because being outside, there’s unlimited ventilation.
Now a couple of other observations…also like
@EmilioTheAnkify has said, you need to correct your uvb. I’m afraid the screw in uvb isn’t able to provide the levels your cutie needs unless she is about 2-3” directly under it. You need to get a linear T5HO fixture (as long as your enclosure is wide) with either a ReptiSun 5.0 or Arcadia 6% uvb bulb. There are units which are a few $$ cheaper than ReptiSun or Arcadia, but I have tested the output of the more reputable one and it is very poor. Correct uvb is one of the areas that can not be compromised upon. Once you get the correct uvb, you then want the basking branch to be about 8-9” below it. I’m not sure why the lamp on the side is there, but I’m going to say to remove it. The light should only be coming from above. The basking area should be the hottest spot at about 80F. You want cooler areas that she can move to when she wants. You want lots of plant cover that she can hide in and take shade under if she wants. You want to recreate a forest edge or tree. I’ll add some pics of my enclosures to give you an idea. You can use natural branches from outside, just avoid pine, eucalyptus and others with sap or strong odor. Give a little scrub with dish soap, blast with the hose to rinse and dry in the sun. To attach them and plants, there are Dragon Ledges
https://dragonstrand.com/dragon-ledges/ which are awesome! You can attach garden trellis to the frame or create a little scaffolding attached to the frame. Never attach anything to the screen…it will rip. Lastly, while your little girl is a bit young right now, she will soon be old enough to reproduce and you’ll need to leave room for a lay bin. This will help when that time comes.

Also, make sure your supplements are perfect - phosphorus free calcium without D3 lightly dusted at every feeding (except when using a different supplement). Then a multivitamin twice a month and a D3 twice a month (not on the same days). The easiest is to use a combination multivitamin and D3 product like Repashy calcium plus LoD or Reptivite with D3 for one feeding every other week.
we’ve all been there I rushed to an emergency vet in the middle of the night and nothing turned out to be wrong… but it’s also this vigilance that makes us good keepers. I hope everything turns out ok
