I'm not going to be much help here since this will be my first pass at filling one up, but I plan on keeping it in the game room upstairs. At the moment I can't dedicate a room, still working on raising the crumbsnatchers. I have a decent size wine fridge I picked up that was not working anymore with a very nice double pane glass door. It has about 14 inches of 11" flexwatt and 2 micro fans, 1 on the top right corner blowing down and the other on the bottom left corner blowing up. The temps stay around 76 - 77 year round in the game room. I put it thru its paces for about 2 weeks and the temps stayed put at 88.3 degrees. That was with a few tubs made up to mock incubating. Oh, and I placed about 12 personal size water bottles at the bottom to assist with stabilizing temps when the door is closed again.

Again, not sure how much of that will help, but I am pleased with the trail run for sure. Hope it helps the effort and good luck!
