You’ll have no trouble at all. I get plenty of smoke flavor from my PK 100. One bowl full makes for some pretty heavy smoke. You might need to stir or tamp down the contents of the bow after a couple hours, but that’s really not a problem at all.
Do use sawdust. Don’t use chips or pellets. I know everyone says to wet the sawdust, but I haven’t seen that make any difference at all, so I don’t bother with it anymore.
