How do I choose?
Hi dubob;
I may have some information which may be of some use to you, as I just tested this yesterday.
Below are the 3 items that I use for supplemental smoke in my pellet smoker.
The Smoke Daddy Heavy D, the A-MA-ZEN smoke tube 12 inch, and the Cave Tools Pellet Tube Wood Smoker Box, which BTW, is said to last up to 8hrs without refilling.
.
The Cave Tools Pellet Tube Wood Smoker Box holds considerably more pellets than does the A-MAZ-N 12 inch tube does
More than twice as many pellets. The above pic shows the Cave Tools Pellet Tube Wood Smoker Box loaded with two loads of pellets from the A-MAZ-N smoke tube, and it's still not full.
I topped it off and lit it, letting it burn for about 15 minutes before blowing it out and putting it inside the grill.
But here is how long it burned in my "cold" smoker.
I repeated the test using the filled to the brim 12 inch A-MAZ-N tube.
The A-MAZ-N tube, actually burned longer. It burned for 4hrs and 1 minute.
The A-MAZ-N tube is smaller and takes up less grill space.
So for those times when I won't be using my Smokedady Heavy D for supplemental smoke, I will be using my A-MAZ-N tube instead of the larger Cave Tools Pellet Tube Wood Smoker Box.
With a hot smoker, expect times for both to be less.
Hope that helps.
