OMGGGGG!
i am so stupid!!!
all this time, i've been thinking,
'ah, i have like, 3 weeks to watch plants grow from seeds'
but i looked up some sites that showed how to grow plants upside down, and NONE of the grew their plants from seeds! They're all just seedlings, or young plants.
WHY DIDN"T THIS OCCUR TO ME BEFORE?
ah well, it'll be easier now.
