Massive fans mean little in an attic grow.

What is the ambient temperature of the attic air to begin with?

Blowing hot air around means little...

My grow box swelters to 90 F in the day, lights off, and 600 CFM being run thru it.

Its in the garage.

You'll need to tell him the attic temps or what ever else he asks, specifically.

Good Luck.
