I started all the rest of our seeds last Sunday - I know very late for us. To speed things up I took the 6 packs and wrapped them in saran wrap and put them under the grow lights - everything including my petunias came up already. The petunias and impatiens were the latest at 3 days - I had amaranthus up in about 36 hours. I am going to do this again next year. I have unwrapped them now - just tented them with the wrap and a toothpick for now.
