Hello fellow smokers! I have been a long time lurker but I finally had to join so that I can finally get an answer to my question. I currently smoke on a pellet smoker but my father had an extra UDS that he bought years ago and let me have it for no cost! I have seen him use it for hanging chickens and ribs. I noticed when I got the UDS delivered that it had a short stack top vent and four 2.25 inch vent holes on the bottom. All the vents don't have the ability to close as I assume the UDS builder built the smoker to run on full air and heat. My question is is there anyway I can control the temps so that its not running at high heat all the time. I would love to do some pork butts, ribs and turkeys at lower temps but my brother has one as well and he says his runs between 350-400 degrees. I have included photos to show what the vents look like. I would love to have the capability to throttle down temps. Any suggestions would be appreciated. Thanks and I am happy to be part of the community!
