Help with cooling

I am, but while you can have too much water, too much co2, too much soil, and even too much light, you can never, ever, have too much security.
Plus, it will create a negative pressure in the whole grow area. This means that in every little crack and micro fissure air can leak through will have air leaking INSIDE, and if air is leaking in, smelly air is no leaking out.
OK, again, thats really nothing more than your opinion, as there is no absolute in security, but just so we can drop this, the air will be vented from outside the grow room, but INSIDE the grow operation (from a cooler veg room), so a filter IS needed. Satisfied? If not, start a different thread.
Te question is:
How much fan is needed to cool 2 600w hps AND thru a carbon filter at the end.

It is a Q thats hard to answer. I don't know by personal experience but read in another thread of someone having a similar prob. and their solution was 2 fans: 1 can fan and one inline. The inline was used for cooling and the can fan for filter. Wish I had the link.Good luck!

Yeah, that looks like the system.
I guess my real question is, how much CPM is needed per watt of HPS lighting?
IE - 600w HPS requires atleast blank CPM to cool to 72 degrees ect ect ect...

sorry dude. saw the vented form outside. to cool 2 600's and finish with a filter would take alot of air movement. your right the ducting would have to be very air tight not to back up and leak. You might think about a system to vent the odor and one to vent the lights. my setup is what you want to do without the filter. Or you might be able to put a fan before and after your lights to stop air from backing to the light.

more to it then just cfm. but 240 cfm will cool just about any light. then ducting size. how far the ducting runs. ambient temps.

Well ive always read that its best to pull air through the filter and not to try and push the air through it, I think if you a fan thats atleast 400cfm if not more you would be fine.
Does anyone know if i am supplementing my grow area with co2 if your lights are air cooled through its own intake and exhaust if you need a carbon fliter?
