not soaking wet, just moist, usually i fill my pot with soil/perlite and then give it a good water but leave it to stand for a couple of days before i pop my seed in, i find it a good idea to do all that the same day i start germ'ing my seeds so after the 2 or 3 days it usually take me to germ the soil has the right moisture, after the seed pops i only water a tiny amount because i always just spray water on the leaves, often. i would pour in around half a cup of water if i was you, not a scientific amount i know!!
