Hello! And welcome to the forums!! Very sweet little cham you have!! It's probably best to fill this out so someone can go over husbandry issues with you.
For lighting, if you follow the chart below you can safely adjust your enclosure to be able to use the t8. Any chance you get, I would def upgrade.
For humidity, I agree w the live plants. You can also use a window kit from a home depot or lowes. I added a picture for reference

You will also want to take a look at the husbandry program on chameleon academy and read through it.
This can be found here:

At some point you will want a lay bin for your girl. I provided some links about egg laying and bins as well. The video is from neptune the chameleon who is also a great resource!
I have attached some plant recommendations, lighting chart, gutloading info, and feeder info.
Filling this out with picture and as much detail as possibly will definitely give you a great start!! Again welcome!!! ❤❤❤
