okay next step, the little white pointy thing is the root tip, you are going to plant the seed about 1/3 " deep with that tip pointing DOWN and cover it very lightly with fine soil and keep it moist but not soaked, warm but not hot, until the cotyledons emerge in a couple days.
dont use any prefertilized soil. the one that says seed starter is okay but you will still want to flush it first by running a bunch of water through it.
