Smoked a few racks of ribs the other day, about 73 degrees ambient temp, about a 10-12 mph wind. Had a lot of trouble getting up to temp, once there, could not maintain without help from a blower. Using Gordon Foods lump (RO in a black bag) in my CharGriller Super Pro w/sfb. Unassisted, the highest I could get was up to 200 deg. That is starting with one chimney of coals started and added to the shaker basket. Was able to get to 250 temporarily when I added another 1/2 chimney of lit coals about an hour into the smoke. This is really frustrating me. Starting to look into purchasing a Stoker Controller from Rock's BBQ. If I have to use a fan, I may as well get technical too.
