tupacboy, every bradley puck will give you 20 mins of smoke, so 6 will give you 2 hours of smoke. Pretty much everything I smoke in my Bradley, I use about 8 pucks, so a little over 2.5 hours. If you don't have any puck savers yet, you'll need to use a couple extra to push the last one off the heated plate and into your catch bowl.

Your Bradley should've come with a catch pan and water bowl. The pan obviously goes on the bottom. The water bowl is to catch the spent pucks, plus add moisture. Depending upon how long you intend to smoke, you'll need to occassionally add water.

Are you doing baby back or regular spare ribs? Like others have said, I smoke mine around 225-250. 4 hours or so for baby backs, 5-6 for spare ribs.
