Around Seattle, gardeners often use granite chips (available at feed
stores, garden centers, stone yards)  for seedling top dressing.   It seems
to help keep the moss down , but not great for keeping Liverwort out of the
pots.     I've used charcoal chips, and more recently crushed mineral
chips( available in garden centers )  which seem to be the most effective
in keeping these seed pot invaders  in check.
For wet, dark winter climates such as ours, mosses , algae , and liverwort
 are a huge problem for seed pots.
