I have a question on my light system .I will be using 6 1000 watt mh/hps with vented hoods. I was planning on running an 8" inline fan rated at like 700+ cfm thru all 6 hoods. I will be drawing in cold outside air do you guys think 1 fan will move enough air for all 6? thanx

Maybe a 12" or 10", but not 8" for 6kw.

You need solid, smooth ducting and a good fan.

depending on the type of hoods you use it may "work" my vented hoods slow down air flow really bad no matter the ducting i use. i have a 435cfm fan on full bore to cool 2 600s thru about 30' of 6" duct work.....

inline liquid heat exchangers... not cheap but effective. u will need a pump tho and either a fan&radiator or a resevoir to cool the water once it leaves the exchange. id go with the radiator

i saw this max fan, its 1000 cfm. it can cool 8 1000's you might need to consiter using something like that. if its still too hot think about using a light mover.
