I do not need a tube for hot smoking...or even warm smoking for that matter.... I run propane and becasue I have such a large volume in my cooking chamber, I can run the gas a little hotter than guys with smaller commercially made set ups.My thought is that dust would probably work in the tube for cold smoking but could catch fire if hot smoking but Todd is likely playing it safe/CYA. Hard to please everyone.indaswamp Are you gonna try hot smoking with it? I plan to make some dust soon and compare to Todd's dust and then someday try hot smoking with it. I think @TomKnollRFV converted to all dust recently and that has piqued my interest.
With one row of jets blocked off on my 18,000BTU burner, I can run as low as 90-200*. I have micro control over the flame to +-3*.
For hot smoking, I pull the 4d nails blocking the jets and run both rows. I can run ~180-275*.
I use the leftover charcoal formed from the previous cook to get a fast flame started. I use mainly chunks on my 16" CI pan.
Pellets are too finicky in my set up and put out white smoke often. With the chunks, I get 4~6 hours of good TBS from a small flame fire. It works for me.....
