The best way to get the most from your standard Hydrofarm reflector unit is to use this kit along with 4" aluminum dryer ducting (sold separately) to exhaust heat and cool your growing are in warm climates or, in cool winter conditions, to recirculate warm air for heating. You can also use vent covers to block unused ports. This method can be used for a single stand-alone light to simply exhaust warm air.
