Hello All, So here I am just starting the coolest thing ever.....Smoking meat!!!!! I'm a chef by trade but I love the BBQ more than anything. I have a Char-Griller Delux Griller w/ SFB. I did my research and used some steel to make a baffle, changed the coal rack and used dryer venting to extend the stack. My confusion is about the size of fire I need to be most affective. I'm just not too sure how much , how little of charcoal to use. I use the chunk charcoal and have several different woods on hand. I read the 5 day course from Jeff (excellent, by the way) but it didn't touch too much on fire size. Any info would help Thank You All, and Happy Smoking!!!
