I started a "big" smoke today, big for me at least. It is also the first time using wood instead of charcoal. I loaded up a charcoal basket with charcoal and then loaded another basket with chunks of oak split down to about 4" square x 10" tall and stood them up. I was able to get about 4 chunks in. It took about 30 minutes to get up to temp and stable at which point my smoke was starting to thin out although not to the TBS point. I had to run a quick errand and when I got back I had thick grey smoke again and temps had started climbing. I was at 280 vs the stable 230 when I left. I expected some grey/white smoke at first but at 1.5 hrs in shouldn't I be seeing TBS already?
