Hahaha, oh my God I feel like such a n00b. The digital thermometers I use aren't acurite, so I have an acurite knockoff(with only one temp reading...choice of reading it from probe or base) and humidity. Then I bought a second little thermometer for just the cool side. Well I assumed that humidity was taken from probe. I was wrong. I was wondering why everytime I move the base unit(I have them on the outside to read easily..probes on inside) the humidity would change. So then I thought "duh...maybe it's read from the base" so I blew on it, and it spiked to over 95%. So I crossed my fingers, and placed the base in the tank. 5 minutes later it went down to 60%. Problem solved!! So all along the humidity was fine at 60 in the tank. It's just my room thats in the 70's. Big d'oh! for me.
