Quick question.... How big are you running of a tank? I ask because I have a 55 gallon that my 09 baby is in and there are ways to make it work..... of course the multiple hides.... I have it where my snake can get from one side of the tank to the other with out bweing seen if he so chooses. Then heat is your second concern.... As of yet I am in California so my ambient temps are nice and warm in my apart. and I am running with only a UTH..... Now humidity is the kicker when it comes to a larger tank, that i hcae seeen..... Now my normal humidty is at 45-50 normal for ambient.. plus I have two water bowls in the tank... now when I see that Rios is getting ready to shed the easiest way that i have seen to bump up the humidity is not the whole tank. Instead... I know that he will not really be leaving his hide while in the process, so I increase the humidity in the hide by placing a damp wash cloth over the hide itself. I am then able to just toss the wash cloth in the washer when it is dirty. I have had Rios for a couple of months now in that kind of set up and it has worked so far with him....
