I've heard Ultratherms are good because they don't get that hot [Leos only need a hot spot of 90F tops], and because the room will be theirs I won't have a problem keeping the ambient temps where they should be.
The 4" tape is big enough for them? I had thought it would be too small. And it's on the outside of the enclosure?
There's a small window in the room, and if that's not enough I need to figure out how to keep the lights on a timer, that would be a plus [because I'm forgetful and might not remember to turn on/off the lights at the right times ^^;]
Ah, I've been meaning to figure out the thermostat issue; if it's just one piece of heat tape then I'd only need one thermostat right? I have another PVC enclosure that will have my Jungle Carpet Python in it and was wondering if there's a thermostat out there that can monitor 2 different temps [and not cost an arm and a leg XD]
