I have read over various threads dating back 6 years and there is not a definitive answer to this question which seems to be somewhat common.
The first time I used the smoker I used the complemtary wood that came with my SM025. The chunk(s) turned to a nice ash. Subsequent smokes week after week and the wood chunks were not turning to ash anymore and the smoke was greatly reduced. Now I get coal chunks. (yes the heat element I tweaked up slightly).
I live not far from the pacific ocean in the foggiest, most damp area of the San Francisco bay area. Even though the wood is stored/protected in the garage the high water content of the air is suspected to be the culprit of the drop off in my smoke production. So I came across a form where a guy suggested microwaving the wood to draw the water back out before smoking. It looks like I have my smoke back.
To me it seems my coal production implies a lack of O2 needed for an actual smolder. So the more wood in the box, the more O2 is needed for a smolder so a higher chance of coal production would result. Does this make sense? Logic may imply that maybe I use too much wood?
So what should I strive for… coal or ash?
Time to brag about the awesome Smoked Salmon I have been making. One $120 trip on a Sausalito boat and I come back with close to 30lbs of salmon. I used an Alton Brown instructions rub for 12 hrs and smoked at 200deg till a temp of 140 and viola… my friends are flabbergasted how good it is. It came out so good I bought a foodsaver at Costco.
