I'm also in the WA area, south by Portland tbh. We're expecting snow all day tomorrow starting tonight, stay cold and then more on tuesday.
I just moved all my snakes to a wire rack, didn't think about the fact that the old location on dressers flushed with the wall would be more insulated.
The wire shelving was purchased with with a t10 and a t12 on the way in mind. However now there is so much air surrounding the tanks(all glass) and I need to insulate them. Been watching temps today and I'm seeing a lot of heat-loss. I started by simply turning on my room heater to raise the ambient, now temps are fine, but right now its the middle of the day, ambient temp will go down at night.
I don't really want to make more mess by cutting up foam, I am thinking about surrounding each tank with blankets. I have lots of those.
Anyway, wishing you luck this weekend. Its gonna be cold and wintry for us WA peeps.
