Zandor I Have A Question Maybe You Know Zandor I'm buying a 1000 Watt HydroFarm DayStar AC Reflector with Glass Lens, Sunlift Hanging Kit and a HydroFarm Powerhouse Switchable Ballast. Now the question is how many CFM's will it take to cool the light? I'll be using a squirrel cage fan and exhausting it through the 6" flange attatched to the reflector. I'm thinking 465cfm's Would you agree with that? Rating: 5
