If those (black thing & white thing) are "hides" they look too tall for a baby rosy boa -& I think you forgot to mention what you plan to be housing...I just happen
to know.Keep the hot side under 90*.
With the lack of insulation in your house, I wouldn't advise ever trying to keep a BP....having a cold room in winter won't work well for that.
As noted in PM, I've read that CHE's tend to burn out quickly when "dimmed"...so if you use that, it should be on a thermostat (full power probably too hot but it
depends on wattage). You'll want to test this out with no snake living inside on a day when you're home so you know how fast it all heats up. Re-test for winter.
Again, I'd insulate most of the glass (back, sides & bottom, "leaving breathing room" for UTH). That "may" be enough for winter, but no way I can be sure...just
as your snake may think it's winter coming if part of the cage is 66* & go off feed. A great way to insulate a tank is to find a cabinet with a big enough space that
tank fits it...slide it out for access. Might be able to re-purpose even a dresser, taking out a few drawers & installing a shelf. I've always enjoyed creatively re-
purposing furniture, & you can check thrift stores for suitable furniture that's not expensive if nothing you already have will work.![]()
