A simple and cheep hydro is the two bucket system. hydro will be quicker and the yeilds are the same if not more.
I would divde the room into 3 8*8 rooms and have 6 plants under each.
Have as many fans as possible, inlet, oscilators and exhaust.
4 soil put 6 of the biggest tubs you can get into an 8*8 space. the more foot room the better.
