Cooling my light...???..

if i buy this reflector for my light Super Sun 2 - 6 Inch Air Cooled Reflector would i most certainly have ot buy this High Tech Garden Supply to hook to the flanges??

I'm thinking of getting a home depot duct 6" fan for my future SSII hood. Don't really know if they are good, but the spec's say it pulls 250 CFM. It's much cheaper and you probably don't have to pay for shipping if you buy it directly from the store.

Whats the specs of your grow room?

veg is 4'l x 8'w x 6'2"h gonna have one 400w mh and flowering room is the same dimensions.

Fans and A/C should be good enough. Just put a fan ripin air right between the light and plants. And pics would be nice too.
