Would it be ok to use a 6 inch 400 cfm fan with an 8 inch raptor using duct reducers? The area is only 5x5, I was just wondering if a 6 inch fan hooked up to a carbon filter will effectively cool the light. (1000 watt hps) could I just buy a duct reducer and go with it, or do I absolutely have to purchase an 8 inch fan
