Hello I think the answers are good . Just a word more. The seed has, with in it, enough energy to get the starter leaves and the first true set of leaves out. My opinion: they need nothing but water up to that point, oh and a peat pellet for the roots. Put the seedling in a 4 inch pot with some ordinary potting soil. A little food at first. Let its root get use to feeding from the soil. They like friendly fungi, helps them digest food. Once it's on the way to its 3 set of leaves, you can put in you living soil. Good Luck. Chuck.
