I'll try to do 225° sometime soon. I typically don't cook that low though. I usually work in the 250° range. After playing with it so far, I don't doubt that I can make it hold 225°. On that initial cook I just lit up a little too much lump to get started. I have also sealed up the air vent a bit and between those two I believe I could get it there.
