55 sq ft cab (2.5x3.5x6.5 ft) roughly. Sealed up in a nice cool basement. Would a 170 cfm inline fan with a nice sized passive intake, along with an oscillating fan inside, be enough ventilation for a 400watt hps? or would I need to get an air cooled hood (which I want to avoid do to duct routing issues in small cab where the only way out is the front, ans it is surrounded by concrete on 3 sides) If i need the air cooled hood, it would have to be a supernova type not an inline so the ducting could both leave thru the front manifold panel above the door. Obv aircooled is ideal, but does one 400wat hps produce that much heat? The ballast will be remoted out of the cab, so just bulb heat would need to be dealt with. I can run the fan constantly, and the hot air is exhausthed outside, so the room temp outside the box would be nice and cool (60-70 topps!) Any help greatly appreciated!
