I personally think it depends on your location and set up. My Jackson seems to be the least fussy of of my chameleons. I actually have my Jackson in a large Exo-Terra cage vs a fresh air cage. With my Jackson I dont use a misting system and he does have a water bowl. Obviously that sounds really bad but out of my Chameleons, he does extremely well. He actually is the most handle friendly out of all my Chameleons, and i have no problem letting him out and walking freely around my house. Most of the time he is content hanging out in a little tree i have for my Chameleons in my living room. So to answer your question, it all depends on your Jackson. They dont seem to be as sensative and stress prone as other types of Chameleons. So every two hours at 12 seconds maybe fine.
