overnight smoking

[BuyLowSellHigh]

I do overnight.  But, I don't leave it until after the smoking is done, burnt pucks are dumped, and bowl is replaced with a disposable 9x13 aluminum pan filled with hot water.  After that I am comfortable with a PID in charge.

I also do the butts and briskets as overnight cooks. As BLSH does, I time it so that the smoke is done before I go to bed and change out the water and burnt pucks. I will also check the water level and grease build up on the v tray before I go to bed.
As RAF stated, you will freak when you see the temp rise prior to stall and go to bed knowing that the IT will overshoot your goal before you wake up. But don't worry it will stall for a long time ;D
I don't worry about a cast iron bowl and just put in the dual element. With it I don't have to worry about recovery times, heat sinks, etc etc. I just use a disposable pan. Of course I have been reusing it and haven't disposed of it yet ::)
