I've been running a digital thermometer/hygrometer for about a week now. Here are my conditions for anyone interested:
Ranges:
Temp: 74-93°
Humidity: 59-74%
Day is usually about 82-92, mostly spent around 87°, humidity avg about 67%.
Night is usually 77, but drops to 74 at least fleetingly every night. Humidity avg about 72%
I have been using a warm mist humidifier as well. The only thing that sucks is my water is horrible (1031ppm), so I have to chisel/CLR the caked on white mineral nonsense every few days. I could use RO water, but since I have to fill the humidifier up 2x per day, I can't afford it ATM (no RO unit, never rains here). It has raised my humidity considerably, and also makes everything much warmer, which I like. The ultrasonic I had just made EVERYTHING wet, but it wasn't very humid for some reason.
