1. You can use the infrared lamp 24/7. There's no need to switch them out. (unless you have them in a dark place that doesn't get sunlight)

2. The warm side seems ok, but 68 is a bit too cool. I think if you can keep it at 72 and no lower you should be fine. The warm side should also help warm the air, and you can always insulate the cage a bit to hold a bit more warmth in.

3. The substrate looks ok, but be warned that cleaning it will be a pain. You may want to consider just using paper towels. (easier to clean and replace when needed)

4. If you're going to have multiple leos you may want to have multiple hides on both sides. They can be as simple as a plastic sandwich container with a hole cut out on the side. To the half coconut hides availabe at the store. You will also want to be able to offer a humid hide as well.

5. Yes you can provide a dish with calcium in it. Rep-Cal’s Ultrafine Phosphorus Free Calcium with D3 supplements would be good.
