Michele - Good point about planting them right away to insure that they are already hydrated. I didn't think of that! That would certainly explain the quick germination you are getting!
Fred - I see that you number each cross, but how do you plant the seedlings? One cross per tray? Do you cut the trays when a cross doesn't take up the entire tray? Or do you mark each and every planting cell with the cross number?
BTW - I've never seen a cleaner seed sowing area in my life! When I plant my seedlings, even being careful, I still make a mess!
