Howdy, new member to the forum. Just purchased a SRG and tried a butt this past weekend. With the lid closed, on low, I was running 450 to 475. Opening the lid, I could get down to 325 or so. This was with a straight out of the box Thermpro TP12.
Any suggestions for lowering the temps?
I did a 7.5# butt in about 5 hours (3 hours lid closed, 1 hour open, 1 hour closed again)
