which is why it has to be kept really wet and checked often.
Maybe try a CHE instead of a light emitting bulb? I switched from a night bulb to a CHE and it doesn't zap my humidity near as much.
With the night bulb I was misting every hour too, now I mist twice daily.
Do you keep two water bowls? keeping one in the cool side to drink and one partly on the heat pad to evaporate can help a lot too.
