Hi everyone, quick question about my vision grill and Smartfire temp controller. I’m smoking an 8lbs brisket flat with lump charcoal and about 5 apple wood chunks. The temp controller is set to 225 which it maintained for about 5 hours and then shot up. I’m guessing this is due to some of the wood chunks catching, but I’m not sure - any thoughts? Second, for anyone who uses a temp controller, do you keep the top vent wide open, or keep it mostly closed as you would when controlling the temp without the Smartfire? Thanks!
