Why does a little 19mm snack take so long to smoke and get to 160. I have a mes 40 with PID and gutted and diffuser plate. It runs perfectly top to bottom, side to middle. Im doing 12# at a time. Have 3 sticks cut to fit above top rack groove. Each stick will hold 7-8 tubes 32” long. I run 90min@120, 70min@130, 3hr@145, 3hrs@160, Then I set it at170 for 5hrs and hope it doesnt shut off. This is my 5th batch in last 2 months. Been taking 11-14hrs. Yesterday was perfect 75* and wind 3-6
