I don't know if I need help on this or not. Started my ribs using the MM. The lid thermometer after about an hour and half temp is reading 210 at lid and steady. I have the vent set at 25 opening. The grate temp is about 191. The temps are rising slowly. IS this ok or should I be higher? If I go to low on the temp's will I be eating at 9:00 pm tonight?
