Im running the exact setup your thinking about. 600 watt m.h. or h.p.s. in grow lab 120 for ventilation i'm using two 4"vortex inine fans one for intake and other exhaust. The Grow Lab is just over 100 cubic feet, the 4" vortex inline fans run at 172 cubic feet per minute. thats what ive been doing and has been working great. the intake/exhaust ports are wide enough for any size ventilation you want.
