Yeah, I did research on here and iherp. Looks like I am going to go with a Zoo Med UTH, a Rheostat and good surge protector for heating my two vivs.
Starting to set up my Rosy Boa enclosure here in a week or two as I decided on it as the next snake I'm getting. Hopefully October 12th or 27th depending on what show has the one I want.
Cruella has been without heat since I got her as our room temps are like 75 - 80 right now (summer/early fall) third floor of our town home in Northern, Va. I'm going to add the same type of heating to her viv this fall so they both have some thermal gradients.
