Ok I have my WSM smoking away on a brisket and St. Louis ribs. I am only going by the dome but it looks like the temp is only 210. If I open the door it spikes close to 250. I have the top vent open and two lower vents closed. I used 3/4 a chimney of coals for my minion method and spread coals across the top. Am I ok at 210? Should I open lower vents? Meat is on the top rack. I keep reading about people getting their WSM over 250. This is only my second smoke but I can't seem to get the hang of my temp. It smells great and lots of smoke coming out.
