Couple questions, I have a 20L setup with a UTH. I just bought a hygrometer you guys helped me find which alerted me to a couple problems. One, my humidity seems to be a little high resting between 65 and 75 and my temp is too low at 82 warm and 75 cool, if I buy a thermostat for my UTH can I crank the heat up or does it only work as a dimmer as in making it only possible to lower the heat. Plus if I turn up the heat isn't my humidity gonna run rampant since my UTH is right under my water dish? I saran wrapped most of the top except for a couple of openings for circulation, since before I had my hygrometer I had no idea what the humidity was and went about all the suggested steps to amp it up. Sorry for the lengthy post, you guys are always a great help, me just starting out and all.
