I've had a horizontal barrel Char-Grill for a few years, used for smoking successfully in the past, I recently added a side firebox to it, yesterday when I was trying to season it, I couldn't get the smoker over 200 degrees. tried for like 3 hours till I ran out of lumps
I used to fill a briquette chimney half full, get it burning on one side of the unit, and put my meat on the other, using this same plan for the side-box was not successful, apparently the dynamics of the heat flow and air flow changed completely. seems that I got to get that firebox stoking hot for the heat to transfer over to the other side.
anyone that's had a horizontal barrel and added a side box, I'm looking for some insight or tips to make this addition successful.
