Hi i think 12 hour is much better. Sunrise to sunset. In the wild they get up with the sun light and start finding their sleep spot when the sun goes down. Do not put fogger over any place thst your cham sits under as this could lead to respitory infection. Now you are in florida which naturally has high humidity levels. You need to take this into consideration with fogging. Since you have a timer, i would consider 2 to 3 hours of light fogging during the am hours. Say 4am to 6:30 am. What i do is before morning feeding and after he has been awake for about an hour i remove all feeding apparatus like bowels and cricket cups then i drench everything trying not to hit him too much and dont hit the lights. There are great hand misters for this that arent too expensive. After drenching i put the cricket cup back in its place i have a stck coming out of it so the crickets can climb out. Then i put crickets in another tall cup with the calcium in it shake it a bit remive the lid and let them crawl out so they drop into the cricket cup. Then i shut the door and prepare the stuff he doesnt have to hunt for. I took the small brown mealwirm bowl and glued it to a heavy rock or the tongue will overturn it every time. I put mealworms, bsfl, and other treats wax worms etc in there after he has hunted the crickets fir a while, a few hours, i return with the snack bowl and he runs over i have the placememt if his feeding bowl below his basking perch so he can bask and eat his snacks. If its been more than a few hours depending on my schedule i mist leaves lightly so he can drink off of them. I try to hand mist at least twice a day and let my hydrometer tell me when i have to fog during the day. The meter should read 50 during the day .and go up to 70 in the arly hours. Luke i said you are in florida so your humidity is natrualky high but if your cage is inside with ac that will change the levels. So you will have to track it a bit with the hydrometer so you can figure the best way to hit the numbers i gave above. now i have my fogger set up in the back corner .not near his basking area. But i do put lettuce in a bowl and set it in that bavk corner as the fogger will help lettuce\collard greens stay fresh for longer. If you have a veiled you should offer lettuce at least a few times a week. If you cham loves it maybe more. I will post a pic i just took of hunter at his basking spot so you can see the set up. Also being in Fl with high heats you might want to consider a dimmer switch on the basking light. Your .bulb should be a basking bulb for reptiles 75 watt . tweeking the cage is a constant continual thing. The pic i will show you has my 6 month old male veil, hunter oh it not letting me drop the pic. I will try another way
