I just started my smoker for the first time, its just a smoker pit like you get at home depot with the fire box off to the left side and a larger grilling area next to it. About an hour ago i started my coal, and put it in the grate right above the bottom of the pit. Then i put my soaked wood right on top of the coal. My problem is even with the vents closed and the stack fully open im getting about 300* on my thermometer... I dont know if that is correct because its an old one off my gas grill, the one that came with my smoker got lost. Now, i have a digital thermometer for powdercoating, i tried using that but everywhere i checked in the grill gave me a different reading. The bottom of the grill gave me like 220 but i dont know if that is correct. My 11lb brisket has been on the grill for about 30 min now, should i just keep it like i have it or should i change it up?
