this aluminum foil duct hose connects with fans, air-cool tube refectors, etc. together. this duct hose can be used to vent grow tents, 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.they have different size from 4" to 12" inches.
