Okay, well I just got my CWD home today, and all afternoon the temp gradient and humidity was PERFECT. But just a few minutes ago my timer set the night time bulb on and I watched the digital hygrometer drop from 80% to 65% in a matter of minutes. How can I stop this from happening? While it was the "day time", the humidity was steady at 80%. I have tin foil on top of the tank keeping most of it in, I have soil compound as a substrate, and alot of fake plants. Lots of wood etc, and a water bowl for him to swim in. I also soaked parts of the soil with lots of water. I'm confused what else to do?
