Can Fan Venting Two 1000 watts

Hey guys, I am about to start my grow up, i am going to be using 2x 1000 watt lights with air cooled hoods. I wanted to have a can fan vent both lights and out the room.. do you think this will work? Or will the heat from the first light make the second too hot?

plz let me know your thoughts. I was thinkin using like 10" or 12" vortex fan.

You can get away with a 6" Vortex.

?If I ran my ms bulb on an hps system, would it distroy the bulb if it only ran for like 5 hours?

so 6" vortex fan would be plenty to vent 2 1000 watts your saying? I want there to be little heat as possible.. if i added a carbon filter do u think i should bump up the cmfs?

Unlike the short response given above, you really need to give us all MORE information in order to give you an intelligent answer.

ALOT of factors determine what size fan (or fans) you will need. For instance-

-Will you be using passive air intakes per light? It sounds like you want to chain them. If that is the case the exhausted heat from the first can def increase the heat load on the second one inline.

-How about the incoming temps of the intakes? What is the ambient temperature of that source you will use for the intakes?

-Will you be drawing air from outside the growroom to vent the lights? Or will you be drawing grow room air straight thru the lights and then out?

-How are the temps in your room now? (before the air cooled hoods)

See how many questions can be asked? And that is for starters. Alot of people grow mediocre bud because of piss poor planning. Properly plan your work and then properly work your plan.

Yeah I wanted to chain the two 1000 watts together on the same ducting. The air would be coming from outside the grow room. could i use 1 can fan to do this? If so how big? or is it too much heat on the second light...

Irrelevant when it comes to venting hoods. The largest hood on the market (Magnum XXXL) is less than 6 cubic feet, x2=12CF, a 6" Vortex is rated at 449 cubic feet per minute. Assuming ducting/hood resistance and we're down to 300CFM. 300/12=25, meaning the air in two hoods are being exchanged every 2.4 seconds. A 6" Vortex is plenty to vent two hoods running 1000's, I ran that exact setup WITH a carbon filter and both hoods were cool to the touch regardless of ambient temps and everything else you're attempting to act intelligent on, nice try though.

I just ran my 2 1000 watters threw a 451 cfm vortex taking air from outside grow rm to attic.Haven't seen no problems.I don't filter fuck em i'm legal.plus in the country or probably would!

thanks badDog.. would a 6" vortex be strong enough to vent a 38 Special can filter 50 and the 2 1000 watts out the room?

Unless you are a psychic (which I highly doubt) none of us (you included) were first informed of the INTAKE paths to the hoods. My brother has done HVAC all his life so that's where my so-called intelligent decisions come from.
When you have ANY hood in a grow room but exhaust grow room air thru the hood via the hood intake and NOT a dedicated intake pipe you have to calculate the cubic feet of the room into the equation. Since the user did NOT state whether the carbon filter was inline with the lights or whether they also wanted to pull hot air out of the growroom and thru the lights ... no intelligent person can simply say 'a 6" Vortex fan will work". Period.

And for the record, I only mentioned that the response you gave was too short based on the LACK of factual information provided to us all. Your ONE application is not the be-all end-all for all users here either. So my response was more than intelligent, thanks. At least the poster was smart enough to clarify his particular setup later , which makes it better for everyone here. Details, details, details.
