I found that if I shut them down too fast that tends to give white smoke sometimes.
That's what I wondered, when I did my test burn the other day, it was 20 degrees and with a 20 mph wind. I was running with intakes wide open and was maintaining bottom shelf temps of 230 -240 and top shelf temps in the 280 - 300 range, this was with 2 small splits added every 30 minutes. For fun I decided to add 4 small splits to see what would happen, and I hit 450+ in my hot spot.
