Yeah, I have a reptisun uvb, its hard to see in the pic because it's in a slimline fixture, you can kinda see it in the second pic. I do have a temp gun, the basking spot is 82-84 (50 watt bulb), the bottom of the cage is 70. It houses my jacksons, so the humidity is between 60 and 80 depending on how recently I've misted (usually 3 times a day). I do agree screen sides would be good, when I designed it, I was worried about crickets escaping, I used 1/4" hardware mesh on the top for it's durability, which a large cricket can get through. I did'nt want to use the smaller stuff on the side because I was afraid it would look cheap. This is the first one I've built, so next time I can correct my mistakes.
