Hi and welcome,
I can only agree with the above mentioned, but in addition to that there´re a few things that are worrying me and I do think a growth tent could work. However at the moment I got some serious question marks and this no offence towards you and we just wanna help, so you and your boy can have a long and happy life together:
1) 2 minutes misting? Where does all the water go? there are no plants in it that can absorb it, therefore the bottom should be soaked then.
2) airflow? I don´t if does flaps on the side can be opened? because otherwise I would recommend adding some pc fans at the bottom to let things dry out and get airflow to prevent stagnant air and bacteria grow.
3) and now the most important, IMHO your boy gets over exposed to UVB. The fixture is inside the tent, creating lots of extra heat next to the primary heat light, and the inside of the tent is one huge reflector. Meaning your boy can´t hide from the UVB and it are for 100% extreme high levels, which will cause troubles on the long term.
For instance check following figure, to see what the safe levels are, blue are the levels which are safe for your cham and that should be in your setting at the bottom.
Like said, I´m convinced this can work, however some adjustments are needed and filling out the form will help us giving the most accurate feedback.
