A good start. What I like to do is fill my container up half way and then pop the seed in, seedlings tend to stretch quite a bit in the beginning. In that manner you can back fill the container up to cover the stalk that stretched.
Added to that, you should never have more that one seedling in a pot, roots will become entangled and kill off each other.
