I do have a reptiSUN 10.0, the long, strip kind; 24". I have two of them (in a double fixture from Home Depot). I read about the coil ones, which is good, otherwise, I probably would have gotten them without knowing any better.
I live in an ancient house (in New Hampshire), and this time of year, parts of my house fall as low as 45 degrees at night, even with the house temp set to 70. She isn't in one of those areas, but during the "dry run", the tank fell to 50 degrees at night with the lights off. Using a 60 watt ceramic heat emitter dimmed to about 20 watts, the tank stays comfortable, with night time temps between 62 and 66 degrees. I don't use the heat emitter during the day.
The basking spot peaks at 109.1; all the temps in all my tanks are measured with Cole-Parmer digital food service temp gauges (the ones I have have a range of 32-392 degrees, accurate to within 2 degrees), and I double (and triple) check with the two temp guns we keep in the snake room.
One of my snakes just graduated to her adult enclosure, and I have a spare cage that's 72"L x 24"D x 17.5" H - I know this might be too much for her right now, but would that be tall enough to accomodate her as an adult? I don't have any other spares, as all my other critters have been raised in 10 or 20 long tanks; should I buy an enclosure larger than the 20 long but smaller than the 6' x 2' cage (it's not dividable

)?
Thank you so much!
