First, early congrats! Also, good job on making sure your husbandry is good BEFORE your cham arrives! This is great!


The community here is happy to see this, I promise. I'll leave the humidity advice to the others who have posted and live in your area, especially because I have the reverse problem. Definitely get your humidity up though, especially for a panther chameleon! It's vital, so keep up the great work!
I did also want to at least put it on your radar that you'll need to upgrade your cage size sooner than you probably think. I got a 3-4 month cham last summer and within just 2-3 months I had to upgrade to the full adult sized cage, haha. They grow REALLY fast! On that same note, take TONS of pictures and definitely do your research on handling early on!
