Amateur grower....need I say more?? :P

Hey I have a real good question! When I sprout seeds which way should I plant them?? Sprout down or up?? Also is there a link someone could give me to a page that deals with identifying strains and cloning?? Any help is greatly appreciated. :D

root tip down.
If you don't know the strain you'll never know unless you find the grower who grew the plant. practicly impossible to tell the strain except for a few distinct ones

so the sprout is the root so I plant the seed up and the sprout in the dirt right??
