Hey guys, got a question. I've recently got into smoking and I have been using my Dyna-Glo Vertical Offset smoker a few times and having lots of trouble keeping the temperature from getting too high to the point my firebox box door has to stay open and sometimes pull out the tray a bit. I have to refuel every every hour and a half and I'm burning through charcoal and wood pretty fast. Anyone have any tips or tricks to help regulate the heat better. Thanks in advance
