Hmmmm---I never used them, but that makes sense.
I am wanting to use it for Jack Daniels Pellets which I found on my first try with them on my 5 x 8 MAZE that they don't provide as much smoke as the other pellets. This was confirmed by Todd that they don't provide as much smoke because they are made from the charcoal the whiskey is filtered thru and not from the raw chips of the barrels. Todd said the charcoal won't provide as much smoke as pellets.
However if Todd said that, you can take it to the Bank!!
