Yes, it has a $10 clip on fan blowing into it. The duct on the other side goes up through a hole in the ceiling to the return duct. The furnace helps create even more of a vacuum when it kicks on. Yea, my reflector has glass, and I wouldn't use a MH without it; they have a tendency to explode occasionally. The hood is barely warm to the touch, ~5in below the glass I get a reading of about 78F during the day with the plastic open. All sealed up it peaks around 81-83F.
