The cage looks great, your Jackson will love all the plants, branches and vines.
One question, do you have a UVB fixture?
One suggestion, elevate the cage off of the floor. Chameleons like to be as high in the air as possible and I have found they are more comfortable when they are at your eye level or above.
Also, for safety, your electrical cords should be elevated and you should have a drip loop. Basically the cords need to fall below the plug and then rise back up to it so any water that runs down the cord will not run into the electrical socket
Which humidifier do you have? Also, what timers are those small ones? I'm new to this and just trying to get good equipment. Very cool set up you have!
It's just a cool-vapor humidifier that I bought at walgreens. I just got some hose at walmart, and luckily, it fit right in the vapor output nice and tight!
And the timers I also got at walmart for like $3.00 each. They only have one plugin, but worth it if you only need one.
