This is for a 56" x 56" x 79" tent/cab.
I currently cool 2 600 watt easycool 6" hoods in my flower tent with 1 fan 6" inline fan 400ish cfm (growbright highflow), It goes intake from outside tent > light > light > Fan > exhaust. I have a seperate 6" fan attached to a carbon filter that keeps negitive pressure on the tent, filter > fan > exhuast.

My question is, if I could add a third hood/light (intake/light/light/light/fan/exhuast) or if I need a bigger fan and if so what size.

Second question, I am currently pulling the air through the hoods, I've read on various forums that some people recommend pushing the air through so that the ducting has a positive pressure, intake > fan > light > light > exhuast, if anyone has further input (if cooling temps are similar etc) on this please share, since it does seem like a good idea to avoid leaks, and I do plan on using co2 next grow. I have always thought inline fans were more effiecent at pulling then pushing, hoping someone proves me wrong =). Any ideas welcome and appreciated.

Thanks
