Um...

You might try the DWC system... just, invest on the costly air stones... trust me, they're worth it. Get the ones of the size you need, and then buy the most expensive ones. The other ones produce bubbles, but the costly ones produce 'smaller' and more bubbles.

As to growing them, and then taking clones... good idea.
That way, you can 'clone for sex', then discard the males... if any. Then, all your clones are female...

How many plants fit in 1 meter square? [1 square meter = 10.7639104 square foot]
So, in 10 square feet, ... I don't know... what's the length and the width?

I think that you could go with 5 gallon paint buckets [5 gallon [US, liquid] = 4.1633709 gallon [UK]] and put one air stone inside each.

Be aware that hydro can give you bigger yields from your girls... but the entrace admission is bigger. I mean, if you want to have 'total' control over your system, you're going to need:
pH tester
ppm meter
EC/TDS meter

hydro nutrients...
pH up and pH down
....

I know there are people over @ Overgrow.com that grow hydro without any of these tools... but, oh well...

What do you think?

I'll relog-in in about 2 -3 hours.
