WOW!!!!
I'll make sure to never get one of those.

De,all I can say is,
I hope everything goes well for you.
Your in a very sticky situation.
BE careful.
I know they are your friend and they are most likely trustworthy.
But people who don't grow don't understand the importance of keeping it a secret.
They most likely will tell people if they havn't already.
Make sure you don't leave your house for the last couple weeks of flowering.
Or you could come home to nothing.

I really truely hope I am wrong.
But from my experience this is ussually how it goes down.
