That better work just great, because bghydro recommends a 4" centrifugal fan, just one, for the HydroHut standard or the mini, and both of your fans are more powerful than that. I'm gonna be using just one 4" fan (170 CFM) in a HydroHut standard, with a 1000-watt light in an air-cooled hood. I may have probs, we'll see, but YOU certainly shouldn't have any!
