Ok I am only using the heat lamp I have a mesh top with the locking clips ok yes I have 2 logs my little bp stayed in it all the time but what is the best hide out?? I am using black sand on one side n pine on the other I know no that Im not supposed to use either pet store said it was ok at the time. There is one little hole in castle my little bp would get in and wouldn't get stuck but I see your point of view all I have right now is a thermometer they pet store said I really didn't have to have a humidity thermometer and no heating pad could never find one
