2 two 6" regular inlines enough to cool 600w?

i have a 600w hps with euro reflector and i'm wondering if two 6" regular inline fans from say i don't know like home depot or something, would be enough to cool this 600w? i also have an Valueline inline fan/charcoal filter combo that i could run in a line fan<light<filter but i was wondering if the 2 6" regular inline will work for cooling b/c i'm working with a small space and want max air cooling. so vents for light and room. i don't have ac units to cool it so i think alot of air movement will keep the plants growing nice(good air exchange=more co2 to use) and will keep temps down. i'm working with a space a little under a sq meter you could call it overkill, i call it overcool. so let me know, thanks to all in advance!

Im sure it would but without knowing the cfm of the said fans we couldnt say 4 sure

Those "inline" fans are duct boosters, not really the right tool for the job. You'd be better suited to get another one of those valueline fans.

alright thanks guys!

hey loghead how does that valueline fan work for you, is it noisy? im thinking about getting one, has it given you any trouble?

i haven't gotten a chance to fully use it, but yeah it is loud. louder than i though but it does pull a lot of air.

Obviously you will need to figure this out based upon your grow op, but this is how mine is set up:
I have 2 600w HPS vented lights, both vented with one inline duct booster fan. It draws air from my attic, and dumps air back into another part of my attic (closed system) Then I have a 6" elicent duct fan (pulls 305cfm) sitting on top of a "phresh" filter venting cleaned air into the attic, this fan is on a thermostat:

you can get em for around 30, or less, just shop around. Oh almost forgot, I have a passive intake, 12x8 (I think) vent, connected to my crawl space under my house. this provides cool fresh air, and keeps my temps in line. Good luck.

I have three of the 6" fans (also two of their 4") and they work well but are quite loud - however, they're the only five centrifugal fans I've ever owned, so I can't say if they're any louder then say a Vortex or another name brand.

But they work great.
