Been testing for temperature control and fuel usage. I've used both briquet's and lump with excellent results although lump leaves a lot less ash.
Below is a chart I made using lump. It took me about 1.5 hrs. to get the vents adjusted after that I basically walked away
After 8.5 hrs. the wife and I got hungry. I was pleased with the results so I cranked up the temp and made some burgers.
This weekend I'm going with a slab of ribs. Will post that start to finish.
Thanks for looking
