New Grow...Planning stages

So I have just sexed my plants and ended up with 6/10 being female. Not bad when 5 feminized cost as much as 10 regualr if not more. So i have these mother plants that I took the test clones off of and I want to start a perpetual SOG aero grow. I have a closet running as my mother/eventual clone chamber, no worries there, but the only extra space I have in my house (a little 2 BR, every room including basement is full) is 8'Lx6'W but only 5' tall (its inside, insulated, and has possiblity for full ventilation if needed). So my plans are to run 3 or 4 432W 4 ft. 8 bulb t5's with a stinkbud-esque aero system sitting on the ground with no veg after rooting in order to keep plants low. Or I was thinking about setting up a vertical style op with 2 400 or 600 W HPS in cool tubes. I figure I could only use the HID lights in a vertical setup since the plants cant come to close to the light and 5 feet is very limiting in space.

So what Im looking for is...
1)whether or not running multiple t5's on a flat aeroset up would be worth the trouble?
2)is running 800-1200 W in a 6'x6'x5' box vertical grow a better option
3)anyother lighting/setup ideas.

Im pretty much set on running an aero system, I like not having to handle all that medium.
Im a new member/poster on RIU and just want to thank everyone on here for putting your ideas up to get me this far. Also, thanks for any input, sorry its kind of vague

cool tubes should work i used 2 600s in cooltubes in a room not a lot bigger they work best if u use 2 fans 1 2 vent the cooltubes and i to vent the room

In terms of maximizing yield for this space, but still being able to have fun being stoned and creative designing it...haha, Im wondering what you think of quality/quantity between running 3x432W T-5's (flat grow) or being fancy and doing a vertical grow with 2 600 W HPS in that short space...would 5x5 be enough room to avoid plant buring (I have whiteberry, white widow, northern lights, blueberry, and a northern lightsxblueberry cross...anyone with exp w/ these strains think they'd stretch too far and burn? I have no experience with cool tubes but have only herad great things from people.

with a good fan on the cool tubes i have acualy had buds touching the glass with out burning them i dont recomend this but you do have a little room for error if they get to big as far as strains go i would go for somthing more on the indica side rather than sativa
