Air cooling 8k

So I'm setting up a 8k set up with a combination of 6" and 8" hoods 4x of each. What is the most efficient way of cooling these hoods. I only have one window to intake from and my room is not entirely filled with right angles. I made up a rudimentary sketch of the possible light lay out of my new room. The four 6" hoods on the right are already in action. I also posted a diagram that I found online. Has anyone used a system like this before?

Much appreciated

You should have one exhaust on the opposite end of the intake, rather than having two, as you have it now. If you use a decent size fan you won't have to bother but if you want to get the plants REALLY REALLY REALLY close you might throw in a duct booster or two but it's likely unnecessary.

As of now I use two 8" hurricanes to cool my two rows of 2 1000watt hoods. Would 1 suffice if I use a Y to connect my rows at the end

Remember for ducting you want insulated, short, straight runs.

Each turn in your ducting degrades airflow, a Y-splitter in your runs not only turns your airflow, it also cuts it in half. That is why you'd get less than half of the airflow between both runs. So less than half of the 750cfm will be going to each run. I don't know if that's enough. I would like at least 400cfm per 1000w, but it gets hot in the summer and I have no a/c.

Its hard to say.....personally I would probably choose 6k. suck air, out window if you want, carbon filters, passive intake, 2 fans.

I tend to setup rooms where you have to be a ninja to walk around, that gets old fast, and the plants suffer from less care.

Yes the set up I have now allows no walking around. Its all on halo irrigation and lollipoped. Also netted. but i was hoping in my expansion, that issue would be taken care of. and at the same time hoping to exhaust into the house to use as heating.
