LOL
my idea to fix this: its probably stupid.
to fix this you will need
a kidde pool about 2ft deep
2 patio chairs that lay down.
some soil, or whatever you are using.
you will fill the kiddle pool with water up to a foot, lay the plant down pot sideways on the wall of the pool: lay the rest of the plant on the patio chairs in they laying position.
so now you water the kiddie pool. the roots will start moving in to the pool, you start adding dirt as the roots climb out of the pot.
...now you just need 7ft of lighting =x
