The following information is based on tube processing with gentle but constant agitation at 72 degrees F.

N-3 7:00 minutes
N-2 8:30 minutes
N-1 11:30 minutes
N 16:30 minutes

For N or N + develoment I would recommend switching to to the 2:2:100 dilution for more reasobable develoment times.

Sandy, The N time for the 2:2:100 (printing on AZO) is stil 11:30, right?
