4'' Flexible Plastic Duct Hose 20': G
Connects fans and reflectors together. This ducting can be used to vent grow rooms, lighting systems and cooling systems. When cooling lighting systems it is best to take air from outdoors or from another room in the house and run that cool air through the reflectors, then shoot the heated air back outdoors. This will keep temperatures down and if your using bottled carbon dioxide it will keep your CO2 levels up.
