just a quick tip, next time put more soil into the pot, you can pretty much put it right to the brim.. the soil will compact down probably about an inch over time as you add water to it... you don;t want the soil level to get too low, otherwise stale air can get stuck in the top of the pot.

you can add more to the top of the pot now, but don;t bury the cotyledons.

looks good so far though
