Stop watering. Moss only grows where it is too wet.

Yep, the school sweet peas have succumbed to moss. Children LOVE watering

I pop a little bit of vermiculite on top of my seed's/seedlings I find this helps keep the moss problem at bay.

i use vermiculite too, especially at this time of the year when the plants really don't use as much water as I would think they do

Vermiculite here too.
