My last smoke was my first smoke. I had the feeling towards the end that I was using too many wood chips. This morning I was getting the smoker ready for my smoke today and saw this when I pulled out the chip tray. Check out all the unburned chips. I guess that confirms my question that I was using too many. I've been reading on here that people use 7-10 quarter sized chips for each load 45 min to 1 hour apart. This is for the MES. So I plan on using that technique today. Also, I plan on reusing a bunch of these. Even the black ones that are slightly charcoaled. Should that be a problem?
