This ^FILTER>FAN>HOOD>DUCT OUTSIDE TENT.
Don't pull hot air through your fan. It kills it quick.
The only time that's not the case is if non insulated ducting is used and the exhaust/hot side of the ducting run is long.
If you're running like 10+ feet of non insulated aluminium ducting by the time the hot air reaches the end of the ducting run, it's no longer hot. Non insulated aluminium ducting radiates the heat from the duct like a heatsink out into the room.
So if it's a long ass ducting run tossing a fan at the end of the line won't cook the fan as badly, but it's still not ideal imo.
