Get a humidity gage and ask your local pet store what humidity would be best. best.Then get a spray bottle and fill it with warm water, remember when it sprays out it will be slightly colder than when you put it in (don't ask me why) and then spray around the sides of the tanks, not on the snake. There are other ways to keep your pet warm too like getting a heating pad wich is what i have along with a heating lamp wich is what i have on in my tank wich has my 5 foot ball pithon inside. Remember snakes ahve hve cold blood literlaly. literaly. Hope this helps. Sammy G AKA Samantha suprisingly age 11! =)=)=)=)=)=(
