I started a few small trays of lettuce seed in the Ultrasorb a couple of days ago and the germination is terrific. I bottom watered the DE and then put in a few seed and lightly sprinkled with the dry DE to cover and left it in the water tray til it was wet. I usually don't put any seed starting mix on top of lettuce seed because they germinate better with some light but the DE seems to allow in more light for germination.
