I have a char-griller pro with a Side fire box. I user Royal Oak Natural lump charcoal. Once I got the fire going, (1 chimmney of red hot coals, poured that into the box, then dump two more chimmney fulls on top of the coals.) Open the vent and stack full open. Once it's up to temp, I close the vent down about 3/4 closed and add my wood chunks. After that, about every hour or so, I just pour on a chimmney full of unlit charcoal. Do you see any problem with that? Should I only be pouring in red hot lit coals? My smokes so far have been very good. Just curious if I am doing something that can bite me is the A$$ later.
