This will be our first winter with the reps and I'm a little worried about their tanks not holding heat too well. The weekend was cool enough to have the windows open, but no too low temps overnight. Didn't watch tv all day/night Sunday, played Halo Reach with family. *lol* Then Monday morning I woke up to 58f and the kids & I were runnin to tanks checkin & huggin reps while gettin the heat up, in & out, for them. (Boga the beardie was NOT happy with a 5am wake up, first true full black beard we've seen from him *lol*) Here's the list of who's in what. All tanks are glass with screen tops. 70breeder for bearded dragon with slate tile bottom basking lamp in use ceramic heater is available (I was told by pet store we needed a lamp & ceramic heat in use together, then learned quickly not so) split screen top (you can slide open one side with other side closed) 55breeder for leopard gecko with slate tile bottom UTH in use screen top one piece, life off top red lights helping with extra heat if needed (not yet needed) 40breeder for ball python with aspen bedding UTH in use screen top one piece, slides forward & off, locks in front red light helping with extra heat if needed (not yet needed) I'm getting ceramic heaters for the leo and python, payday is Friday, and am thinking it would be a good idea to have some plywood cut for the tops of the tanks and have holes for the heaters. I've read this is a good thing to do in a lot of heating threads. Wish me luck on pulling the "female with no male to help her cut the wood can you the hardware store guy do it for me" routine. *LOL* My real concern is the glass sides of the tanks. Should I get some of that insulation foam board cut to fit the outside of the tanks and just tape it on 3 sides to help retain heat? I was talking to a hardware guy about insulation and the tanks and he showed me the board and wondered if that would help. Wooden enclosures are in our future, I just didn't expect this sudden temp drop this early in the year. I'm really not likin Texas weather, the South was MUCH easier to live in. *lol* Thanks for advice and ideas.
