I always start my seeds off in a 1.5 x 1.5 cube (rockwool)
and then into a 16oz cup of dirt after they show a root (2-3 days)

with a small cup, they can cycle between wet and dry
that big pot won't dry out for over a week
since the bottom of it stays too wet...it becomes more acid
the roots won't grow into the soggy soil in the bottom
you get root rot and death

sure sign of overwatering in seedlings is death from the tips of the leaves...and slow to no growth
