maybe, i cool 1 600whps with a 6" fan it its overkill, but 2 more i sorta doubt it, maybe to fans one pulling one pushing air through. just my thoughts...

You need at least an 8 inch fan............Peace

I use one 8" Vortex on 3 1000watt fans.
But, the line is actually reduced to 6".
My fan is hooked directly to my hood(no cooltubes).
But, my lights are in very close quarters.
So I think it is possible.
But I would also suggest you use a 8" as well, even if you have to reduce it.
It doesn't cost much more then a 6".

Nice link Tom, I am bout to buy that 8 inch probably.. I have no idea why somebody wouldn't just go ahead and pay 20 bucks to almost double the cfm, seems worth it to me.

Okay. So the general consensus so far is that it's not definite, but you wouldn't suggest it. I really can't afford to spend any more money, never mind £50 on a new fan.
So how about this: 2 of the lights connected to a 6" fan, and 1 light connected to a 4" fan. Then I can connect them both up with a Y-piece before exiting the hot air.

I would run the three lights on their own exhaust. Have the 6 inch fan pulling air from outside the grow room through the three hoods and back outside the grow room. Than take the 4 inch fan and use that for your room exhaust. That is your best bet with your current situation I would think

Those fans seem a little pricey and the CFM's aren't that spectacular

they are well built and can handle a (dimmer switch)speed control

one pushing one pulling would be perfect for that

well they aren't the super high cfm, super LOUD, centrifugal fans that cost up to 500$ or more but they are all you need for cooling lights. those other fans are made to distribute air throughout a whole house(atleast one level) and light setups usually max out at 50' for 4 refectors in one or two ducts and this just doesn't require a 500$ fan.

That was my initial thought.
But the instruction manual that came with the 6" fan says that temperatures should not exceed 40 degrees Celsius (about 105 degrees Fahrenheit.). I can see 3 x 600w bulbs far exceeding that. That is what I'm concerned about.

It's an attic grow, so to bring in fresh air like that I would need to run the ducting 10 feet to the edge of the roof where there is a crack, then through the lights.
10 feet, plus another 4 feet to connect the lights. Will it be powerful enough?
