I'm in the minority here. Run it with water. Makes a great govoner on temps.
Full charcoal ring with scattered wood chunks. Dump a 1/2 chimney of lit coals on top. Start with lower vents 1/2 open. when it gets to 225 close down to 1/4 to 1/8 open. It will hold 225 all day. Charcoal is cheap. Make it easy on yourself.
