very close to the top....u almost want the top of the seed pokin out...but not quite....other people germ them in a paper towel first and then put them in...but I was 2 out of 3 by just placing the seed right in the pod....hope this helps
You wanna watch the taproot and make sure it goes downward .. I poke a hole through the sponge or cut in 1/2 longways to help the root find its way down
