Thanks
@LightningBoldtz that post gave me a tip I could use to gets pics posted. I was even able to use Google drive.
We're running test cooks to graph time and temp with the Slow 'N Sear on a 22" kettle. This graph/cook was done two days ago. I adjusted the vents one time as the temperature approached 225F at the 20 minute mark and after that I did not touch a vent setting or open the kettle for the entire test.
At the 2 hour point the afternoon sun hit the kettle and caused temps to bump up a little. There was a brief summer shower 5 hours into the cook that caused a sharp downward trend in temp. At 7 hours 30 minutes I lit the 26" kettle right next to the test kettle, which caused the test kettle to heat up a bit. Even with these things going on the kettle with Slow 'N Sear combo maintained low and slow cooking temps for 10 hours unattended.
Test was done with one load of charcoal (single Weber Chimney) and one quart of water added to the reservoir at the beginning of the cook.
How's that for "set and forget"?
