I seriuosly, would wait.

my parents ( well, back when I was an "in home" child) would have NEVER allowed the cultivation of MJ in the house.
Seriously dude, I'd just chill, and wait until youve got a place of your own.
especally if you hide even your consumption of weed. they will flip 10X's worse if they figure out your growing.

then they will also think your dealing.
just believe me on this, parents ALWAYS assume the worst.

just wait, for both better seeds, and your own place

..and teh "have somebody else grow it" thing..
is just..retarded
