I spray for 3-4 minutes in the morning and night and I spray for a minute or two between those misting sessions. That hand mister In the picture I use, i try to spray the whole thing in the morning and night then about half of it every other misting. Some people do it for way longer and night say I'm not doing it long enough. You can wrap the cage with shower curtain or tarp to help the mist from spraying every where and to help keep humidity up.
