I bought 2 bp now. I really really like them and they are doing great. I kept them in my one bed room condo, in 4 tub rack. I only used 2, and the other 2 I use when I need to clean them.

I use the heating pad and kept the hot spot 86 to 90, usually about 87, 88.

Then when I read online it says, the hot spot needs to be 86 to 90, the cold spot needs to be 78 to 85. How can I make the cold spot from 78 to 85? I set my room temp for 75, it is already too hot for me in this little condo, I can't go 85.

My snakes are doing fine, I just worry about them. What can I do?

Thanks
