The only thing I might add...according to your plans, the exhaust MUST or SHOULD be far away from the intake.

These fans have massive power and will suck air from whereever it gets it.

Just make sure the exhaust does not get sucked back into the grow room. The plants have already used the air and need fresh CO2.

But again, you are accomplishing the same thing either set-up.

For sure, everything within the system is air tightened with duct clips and fast clamps if necessary. I'm not sure how well the lights will be cooled because the air will be taking in from the grow room, not outside, but hopefully the setup is such that the lights don't even get a chance to raise the grow room temperature a single degree. Passive intake at the bottom and a small occilating fan should help counteract any temperature increase. Will hopefully find a cheap 'environmental controller' so the ventilation is more effective.
