I am new to smoking and can really use some help. I am having issues keeping my temp. steady. I am having to keep the bottom door open just to keep the temp down. Today is my second time using the smoker and I wrapped my soaked chips in aluminum with holes in it. I got good smoke for like 30 minutes. Then I took them out of the aluminum because of some other info I read online. However, I cant keep the damn temp down to 225-250. It just steadily rises and I have the flame from the propane tank as low as possible. Help please???!
