The terrarium is built right. The humidity is landed on just the right range for my animal. However, there are sometimes a few days that the humidity would go up ABOVE the recommended range. This is occasional and does not warrant drilling extra holes or anything like that, as the thing is glass anyway. So if the humidity is low, I mist it. If it is too high, what do I do to reduce it? I'm talking about these once in a while we get a wet week kind of thing. Not a permanent problem that warrants an entire redesign of the habitat. Sort of like the "opposite of misting" if you know what I mean.
