Lit a fire at 9 last night for my first butt. Built it from a new bag of lump starting with large pieces on the bottom and smaller toward the top. Checked to make sure the dome thermo would not hit the meat. Let it burn an hour to stabilize at 225* and then put the butt on. Watched it for an hour and everything seemed to be doing well. Went to bed and checked it at 3 am and temp was at around 200*. Got up at 6 am to a cold grill and no fire. Got it lit again and was thinking of going 275 to finish it today? It seems to me that the plate setter disrupts the air flow and requires larger openings in the vents. Comments?
