Hello all. I am planning my first smoker build. Since there is lots to master I'm not really focusing on an amazing smoker just yet. I'm working on something practical that will teach me the foundations of smoking. I plan on building something that works similar and similar shape to a uds. I have three ideas. They will all be boxed shaped. Either forming a vertical rectangle out of refractory cement, making a basic concrete block smoker, or making a mini wooden smokebox big enough for a brisket or a couple butts. What are the cons to a concrete smoker? I have read they require more wood because there is more mass to heat up? and that the ground they stand on has to heat up too. Is this true? Any other cons to a concrete smoker I should be away of? Since I do plan to practice frequently I don't wanna waste unnecessary money on wood. I guess temperature control will be another issue since I don't get the several uds style valves that open and close to regulate air. Any thoughts about the refractory cement build? I will just for a cast and include the ball valves used in a uds if I go this route.
