re: When do you add your wood chips/chunks for a low and slow smoke?

I don't get a "massive" fire going. I place a few large wood chunks on the bottom, add some lump, and then mix chips/chunks with some lump on top. Light charcoal with vents wide open and get a steady fire going...not a big fire, but just enough for a steady burn that you can reduce to a smolder. Then I move my vents and zero in on the desired temperature.
