i think it would work fine, i am on my first grow with DWC. I have a 7 gal sterilite tub with 2 plants in their 4 week of flower. I have 2 12 inch airstones,the roots have been pretty much totally submerged in the water the whole grow (Deep water culture, I think there is a difference btw DWC and aeroponics which doesnt submerge the roots), and they are meeting my expectations. I have a small chamber and tied mine down quite a bit, (2 x 150 HPS ) aS FAR AS SOLVING FOR X ... MY SETUP IS PRETTY MUCH EXACTLY HOW YOU HAVE IT ILLUSTRATED
