Forgive me all, I am a noob at smoking but I am patiently trying to figure it out. I purchased a propane smoker and have been trying to keep my temps down, the lowest I have been able to get it to us 300 degrees F. All the vents are closed and the gas is as low as I could get it. Any suggestions on what else I can possibly do. If it helps this is the smoker I purchased Masterbuilt Pro MDS 230S Dual Fuel Smoker.
