I would hand mist.
When I had a mister that only sprayed for 60 sec, I would walk by and click it off/on 2 or 3 times during the morning and evening mist sessions. I was fortunate to be home for the cycle tho.
You really dont want to mist many times during the day...but....
If you only have your heat bulb on for a couple hours a day, you can mist either a while before you turn it on, or after it is off.
