I became aware that many people use the CSG in a normal BBQ, and decided to give it a try. But I never did. I use a pellet grill, which would be switched off during this process (we are talking COLD smoking). The cardboard box was a vertical arrangement with ventilation by the tray and out the top. Would my pellet grill, which is more of a horizontal thing, have the same ventilation to keep the CSG smouldering? Should I enable the grill’s fan, or would that be too much?
