I started at least 100 varieties of tomatoes this year, including a few CVs from purchased packs, but mostly saved seed ranging from seed saved between 2000 and 2006. 80 varieties germinated in 3 days, 20 varieties germinated in 4 days, and a very few took a bit longer (typically, Mexico Midget took the longest at 15 days!). I think that the more seed that you plant per cell, and the more cells you plant at the same time, leads to a more uniform "procedure" - with, to me, a main variable being seed depth. Using the 50 cell plug flats that I do generates an assembly line approach, so that you end up with nice, uniform germination times.
