I have cooked a couple butts on my wsm with cyberq atc. normally 8 lbs and it takes about 16 hours at 225. Can I decrease my temp, say to 210, and increase my cook time to around 20 or 22 hours. Not puncturing meat so if I understand correctly, I don't have to worry about the 40 to 140 rule. Just wasn't sure if there is a minimum temp to cook at or a maximum time I can't exceed. I'm trying to start it say 8 to 10 pm and finish say 5 to 7 the next night so it will cook while I'm at work.
