Instructions for growing some plants from seed suggest starting in quite
a small or crowded container and then "potting up".

Do some seedlings actually benefit from not having much growing medium
at an early stage? Or is "potting up" essentially a professional's trick
for saving space?

I have enough space to sow seeds direct into "final size" pots - but
should I?

Thanks!
