Stumpted on ventilation

[GuerillaAk]

I am almost done with all my upgrades(630 cfm fan, 12,000btu ac, 24 pot ebb n gro, and 2 vented hoods) since this old pic of my first grow but i am having a hard time ventilating the 2 hoods that I got to replace the one on the left and right.
The problem I cant turn the hoods side ways to line them up cuz of the slanted ceiling and it would waste alot of the light. i have to exhaust thru the window in the pic. and intake by the door.
I was thinking of putting the fan by the window blowing out and making a 3 way to hook the 3 hoods up to it. and run 3 intake ducks up by the door. I know this wouldnt be ideal but i seen it done kind of like that in a drawing i found if you look up grow room on wikipedia.com. I know it wouldn't be ideal but would it be good enough? any better ideas? I cant wait to get my new LA Woman and sharkbreath seeds going!

Here is the pic from wikipedia. I was thinkin i could hook the hoods up light that but thu the window insted of the ceilding.

I think it would help if you took a picture of your current setup rather than an obsolete one, but I think your plan sounds OK. Deal with what you have and try to keep the bends in your ducting to a minimum. Sometimes hydro stores have strange duct adapters and combiners that are hard to find even at HVAC supply stores that might help you. Maybe diagram it out and get back to us?

I don't have my camera to take a current pic but the lights are the same except the ones on the left and right have vented hoods now. I did take a couple mins to draw up a crude diagram of the 9'x9'x7'H room. hopefully its easy enough to understand. its color coded. I will try to make as little bends in the ducts as i can, in the drawing is just a basic path i could make them follow. which configuration would be better the top or bottom one?

I only hooked up the 1000 watter to the fan. Im not going to exhaust the 2 600 watt hoods. My 12,000 btu AC should be able to keep the room cool. The 600s dont seem to put off nearly as much heat as the 1000s. Now i Just need CO2!

That looks like it should be OK. The key will be making sure the suction is relatively equal through the 3 different runs. If each duct has similar resistance (size, bends, etc) you should be OK. I'm sure you can make it work regardless.
