He very well might be, but, He has some specialized equipment fer the job that we all don't have access to. Use green would in the average smoker on this here forum an yer not gonna like the taste much. As I said before, I don't use green wood an I won't use green wood. It can be done on a limited basis, there are members here on the forum who do so, but, it takes a fair amount a practice ta get yer desired results.
I have burned wood fer heat fer many years, ya burn green would ya get cresote, don't matter ifin its in yer wood stove er yer smoker, green with lower heat an less then perfect combustion air is gonna create cresote. Not good in either case.
Stick with the nice seasoned stuff an enjoy the product yall produce. Just my two coppers worth.
