Back ribs do you spray all the time y/n I'm gonna use the 321 method for the first 3 hours or so. do i spray the ribs with my apple juice water mix every 45 minutes. then wrap in tin foil for 2 more hours or so, then take them out of the wrap and put them back on and spray ever half hour for the last hour or so. Or do i just leave the door shut and not spray them for the first 3 hours and then spray them put in tin foil for 2 hours. then un wrap and spray place back on grill for last hour and then done.
