I have been smoking about a month now and everything is going well so far, the only problem I have is with how long my wood chips smoke. I have had to revisit the "smokiness" every 15 minutes every time I have used my smoker. On average my wood chips last about 3 minutes and then it is nothing. I don't know how to get the smoke to come steady for a good amount of time and any advice would be appreciated. Thanks!
