Fourth cook with a new-to-me WSM 14.5.. first three were pretty good. Since it's the last few days of my vacation, I thought I would pull an all-nighter and do an 8lb pork butt. I fully expected a ten to twelve hour cook, and set myself up to sleep outside (I am a backpacker at heart and sleep in a hammock).
I started at 11 PM. Minion setup. KBB Original. At the suggestion of a reputable local smoker and owner of a BBQ retail store, I opted for sand in the water bowl because I figured water would all evaporate overnight. Might have been a mistake. I started with all vents full open. As soon as I saw 200F at the grate, I started to back down the bottom vents. Shut one completely and the others down to about one-quarter. Temps blew right by my target and up to about 340. Over two hours I have slowly shut all the vents except the top which is at about 10% open and at this point, it's 2:00 AM and the temps have not dropped below 300. Right now it's 311F with everything closed and meat temp is already 144F.
Nothing else I can to get the temp down other than hope for rain or break out the garden hose. Worst case is I ruin a pork butt. I am sure not getting the results I see and read others having.
