New room layout would like criticism

[LL84]

I have been running a 2kw horizontal in a 7x7x7 for a year or two now. I have been itching to make a switch for vertical. I have been debating in taking my room and running 2kw vertical in it or a 5-400 ballast i was thinking about laying out lights in this pattern
x=plant, o=light

oxo
xox
oxo

If it was the 2kw i would do a stadium with 4 on each side like selfhemployed he showed me something i liked. As im approaching summer im thinking lets have fun with something new.

Im hoping some vert guys can give me some advice on the setup one of my concers is how to pull the heat out of 5 cool tubes(such as seperate the lines with two fans for less drag, get on big beast fan and pull through the lights) or if its worth the money for an airconditioner and run the bulbs bare in the room. I currently exhaust my heat up through my chimney so i dont have a build of heat outside of the room.

Marlo did an awesome job with the W.o.W thread that really inspired me in trying these 400's.

I guess some pro or cons and advice from anyone would be good.

Thanks for helping me.

Why not just stack them 1000 watters ya got in the center of the room and do a stacked donut?

RM-aquagrower mmmm thank you i guess that makes alot of sense. i often over think things. i know it seemed like common sense there but if im only trying to do 4 plants so i think im going for the donut? first run.....

I would keep the lights horizontal, but I have never tried vert or stadium before.
