I have been having fits getting my A-MAZE-N tray to smoke. I have a downdraft hood on a Traeger Pro 34” with a Smoke Daddy PID controller. With the fan being off so much the air turnover kept sniffing out my tray. I had a little experiment today with the tray using a combo of wood chips and pellets and activated just the fan with the controller. Smoking like a champ while I was snacking on some cheese after my lawn chores! TEST TIME!!! I have no idea how lownis the best temp but the probe directly in the Cheese is sitting on a steady 89 degrees with a lot of smoke. Wood chips are a blend (apple, cherry, mesquite, pecan) and the pellets are all 100% pecan.
