I'm new to all of this ,never used a forum before so don't know how to post pictures and such. the cold smoker i have built is 4' sq. and 8' high in front and 7'in the back it is 2x4 construction with car siding on the out side. the fire pit is a used wood burning stove that i dug in to the ground so the 6" duct enters the smoke house near the bottom. i drilled 4 3/4" holes for the vents. So far i have used it twice . My first question is: Is there anyone out there that cold smokes with just wood for the heat source and the smoke and lives in the north . I live in Mn. thanks
