I've been germinating about 5 seeds in a cup of water for the past, probably, 2-3 days and all now have a tap root sticking out. Just to be sure, since this is my first, the seeds will be taken out of the water and the tap root will be put into the soil facing DOWN..correct? I'm going to plant my seedlings into solo cups filled with about 25% perlite (its miracle grow "enriched plant food" perlite, think it'll cause problems down the road?) and the soil i have is just basic, cheap walmart soil with no ferts or anything. Thanks for the help.
