Damp-off Here's a non-chemical way. Most books on Damp-off claim it happens with excess moisture and lack of ventalation This is for those closet/ spare corner/ spare room seed starters 1. Find out how much water it takes to really soak your pot with your seed starting/ potting media. 2. When you water, use 25% less than step 1. 3. Allow the soil surface to dry for about 12 hours between waterings 4. Aim a small computer fan at your seedlings, from 3 or 4 ft away. Keep fan running as long as you are growing PLEASE: If you have young'uns around the house, make sure little fingers can't get into the fan. NOTE: It's easier to water 25% more than to start over To those who have recommended Captan in the past, Its banned for most veggie plants. Byron
