I have tried BBQ briquettes, but there are some issues with them. First, they may contain traces of harmful metals or chemicals, since the charcoal is made from coal and industrial byproducts; you wouldn't want to put those in the ground. Second, they are much harder to fragment and powder than lump charcoal. If you can, hold out for the lump wood charcoal. That's what I eventually used in all my pots. I made my powder by putting the lumps into a burlap bag, wetting it (to reduce the dust), and jumping on it. It's an inefficient method, and certainly not feasible for large-scale powder charcoal production, but it was enough to test in my pots. I got 10 lbs of lump charcoal from Wal-Mart for about $5. Not too bad.
