I am currently attempting my first ever smoke. I have a vertical barrel charcoal smoker. Chamber temp was last I checked about 215 degrees. Been that way a couple hours now. I just added some more charcoal and chips to bring the temp back up. It cooled of to around 175. I put a dry rub on and it's been smoking a total of abou 3.5 hours. Internal temp is about 120. Any suggestions on bring the internal temp up so I can get it done. It smells fantastic. I'm using a mi of hickory and apple. Thanks in advance. I forgot to take a befor pic but her is what it looks like from last temp reading.
