How many CFM for 3-1000w hoods?

[Casual]

Hey all... I'm helping a buddy out with three 4x4x6 tents. Each tent will have a 1K sealed 6" hood. I'm planning on daisy chaining all three hoods together, basically going from tent to tent to tent. I'm thinking about using the same fan to cool the lights as I am for the scrubber. I'd like to get some opinions from all of you as to how much CFM to run. He'll be running a separate fan/scrubber combo. The air supply for the hoods will be pulled from the room and exhausted outside. No Co2 at this point.
Do you all think a single 6" 450cfm fan is enough?

Thanks!

Caz

cfm's

You would want about 300 cfm going through each hood so a 1000 cfm fan would work great for 3 1000's. J:afroweed:

I believe my fan is about 760 cfm and I run through 4 xxl hoods. It will depend on your temp of air coming in

i'm using a
Valueline 8 Inch 745 CFM Centrifugal Inline Fan
[500510-3]
$99.90

from http://www.businesslights.com/valueline-inch-745-cfm-centrifugal-inline-fan-p-2046.html

on 3 6" Magnum XXXL hoods and it is working just fine. the last light has a lil more heat then the first so maybe a small booster would help but i have no temp issues for sure with this setup. FYI that's a 8" so you need to get a reducer and push the air through not pull!
