So trying to get everybodys input/experience with charcoal consumption in a cheap offset. I recently ran a butt for 8 hours and used 2/3 of a 20lb bag of rockwood lump charcoal. I never experienced any temperature spikes but did have to battle to keep the temps up at 250°. I think one thing i still need/want to try is adding firebricks to the cooking chamber. Also, i think i may need to lift my charcoal basket further off the bottom of the firebox. I chose rockwood because i found a consumer review list and it was one of the highest recommended companies so i figured why not. Lets hear some feedback and thanks in advance!!
