I started this thread in a group but wanted as many mini users to give feedback as possible. I am sure there are other threads too...just haven't sifted through them all....YET. I have seen some posts/qviews with mini users talking about High Heat (above 300 +). My mini holds 250 perfectly for about 5 hours. If it dips, I can stir up the coals and keep it going at 250 for about 6 - 7 hours with a single batch of coals.It is really efficient. Any suggestions on getting a higher temp without cutting out the bottom, which is something I can't do.I didn't have the tools to cut out the bottom of my steamer pot for my mini build. I had to go with drilled holes. Now for Charcoal? I have tried both Kingsford and Stubb's charcoal and found that Stubb's last longer and produces less ash which is good for my mini since I have bottom vents with an metal ash cover (it's an original smokey joe from the 1980's, basically a silver...and is working great). I guess it is all about personal preference, I am just curious about others and results people have had? briquets vs. lump? whatcha think? Thanks!
