Wow, you guys like it warm! I usually keep our house anywhere between 67 and 69 pretty much year round. I keep the vents in the snake room closed so it stays noticeably warmer then the rest off the house. Ambient in my enclosure stays in the mid 80s using a che. Warm side and cool side stay in the low 90s and low 80s with humidity usually hanging in the low to mid 50s with misting of sphagnum moss every other day or so. This is using a 40 gallon breeder with 3/4 of the top covered.
