I am thinking of purchasing some wood for smoking online and there are many different options as far as amount is concerned. I was wondering, roughly, how many smaller log splits it takes to do a 10 hour smoke? I'm thinking of doing a brisket and I will be using an Old Country BBQ Pits Wrangler smoker. The 30lb box has about 30-35 splits. I know I will likely need to add coals every hour or so, but how often do I need to add more wood? Any help would be greatly appreciated!
