Seems like I've been posting questions left and right, so I apologize, but it's the easiest way to get the right answers opposed to guessing. I use a 20g Long with a UTH under both sides (I have heat lamps, but I don't like using them b/c they dry the air out too much). If my warm side is 90-94 and my cold side is 80-84, but the ambient air temps average around 72, is that something that needs to be changed? When I had the heat lamp working, the ambient temps were around 80, but I wasn't sure if it mattered too much as long as the ground temps were right. Thanks for putting up with all my questions!
