I'm having some weirdness with the vivarium I set up this morning. I've been watching the humidity, as I'm going to be adding bumble bee toads to it after their QT, and the humidity is a bit too high at 75%. Now today it's a bit sticky where I live, so this might be part of it. I don't have AC so whatever it is outside, it's usually the same inside.

However, on a whim, I removed the hygrometer and held it in another spot in the tank, actually right over the bathing pool, at the very top. Right now it's back on its' velcro hook behind the wood and among the plants. But when I held it over what I had intended to be the "wettest" part of the vivarium, the humidity dropped. Like 5-6%.

I'm weirded out by this. I planted the tank so that the grasses growing out of the bathing pool would (hopefully) create humid pockets, as I expected the tank to be a bit on the dry side. So frankly I'm concerned about my toads' health.
