i dont have a humidity dome, so my plan was to put the seeds into the moist rockwool, put each cube into a plastic cup, then cover the cups with plastic wrap. will that get them to sprout? is so, how often to i re-moisten them? also how long after they sprout until i move them to my dwc? i also have an aerogarden (they will grow in a different dwc i made) but no sponge things....is there a way to use rockwool in the aerogarden to sprout them and then move to the dwc??
