I have to disagree - ventilationis always important for seedlngs (for
all plants for that matter) the moosy covering is NOT a sign of damping
off - it is a totally normal phenomenon and should not affect your
seedlings - certainly, do not overwater - xometimes the moisture of a
moss-covered pot is misleading.
By the way -- if you do start to have damping-off, or suspect any type
of fungus - the cure is easy -Make sure you have adust mask for your
mouth and nose before you try this -- just sprinkle a little dry Captan
or Benomyl directly on the soil, then mist in well --no need to dilute -
your watering will do it for you.
