You won't be able to control the temps if you crack the hood, microwave the pellets is the best advice to give.For those that have trouble keeping a tube going while in their smoker (assuming you got it started properly with a torch and let it go for 5 min or so before placing in the smoker) try wedging a nickel between the hood to allow a small crack to increase the air flow slightly. Place the open end of the tube perpendicular to the crack.
