It seems like if you use slate as a substrate as I have made the switch today. You can either lose the UTH or the Heat Lamp, as the slate holds temp so well that both are overkill. Can someone who uses slate as their substrate tell me how they control their temperature? Even if someone has something similar, I'd like to know different methods because I killed my bulbs for the night as the warm side of their vivs were getting upwards of 95 and I don't want to cook my geckos.
