Thats a lot of misting... Make sure the catge dries out in between and especially at night. I would say when it comes to Jacksons, as much as possible but still allowing a good dryout as described.
I mist 4x a day, for decreasing periods.. My panthers are on the same schedule, so I have to strike a balance...
7:30 - 12 minutes
11:30 - 9 minutes
2:00 - 6 minutes
4:30 - 4 minutes
