Phil Thats about what I am aiming for I has read other posts so was did have a clue. I am using a slow cooker.But aint to shure what tmperatue it will attain so Ill keep an eye on it and If it gets to 72 Ill turn it off for a bit until the temperature starts to drop.This is going to mean I need to be monitering constantly but I am taking reading and notes so it should be easier next time.
Many thanks Jim
