Dear Diana: You'll also want to change the conditions that allowed damping off to occur in your seedlings. Use warm water, bottom water and don't keep the soil too wet helps. Also a fan keeps the foliage dry. After germination I move my seedlings into a lower temperature breezy environment. Also look at your seed starting mix you may want to add a little perlite to create faster drainage. Good luck. Don't wait until next spring for seeds. Start some summer seeds. Best,Vicki
