I just germ'd a few blue mystics in some styro cups full of ocean forest. I used about a half and half mix with perlite just because I didn't wanna burn up the delicate little things with that super nutrient rich soil.

So yeah.. I'd half/half it and get the soil nice and wet. With all the perlite in it, it might dry out so just keep an eye on it. If it does dry out be real careful watering, don't want to flood the seed out of the soil. Keep the soil damp till it pokes it's head out. Then at that point just water it like a normal plant, ie wet it, let it dry, wet it again.
