Cooling two grow rooms from one vent fan

I was thinking of buying this:

and connecting it with some ducting to split it into two grow rooms that I have set up. (image attached)

It's rated at 430CFM. Would this be sufficient? My main concern is noise level since the grow room is right in my living room where I do all of my work.

I want to buy two, so I can draw hot air from the top of both while blowing in cool co2 enriched air into both.

How big are your rooms and what lights ate you using

One is 36x20x62" and the other is 48x48x79". 400w HPS in the smaller one and 600w MH in the bigger one.

I understand that I would want to circulate whole volume every 5-8 minutes so 430 CFM should work. I understand flow won't be that high since it's a little restricted through ducting and it's being split two ways but I'm currently not running anything and temps are fine so I figured it would be sufficient. The 8" version of the fan is just $5 more and flows over 700 CFM, but I don't know if I would be able to connect that to 6" and 4" ducting. I should be able to reduce it to 6" from 8" but I'm still researching 8" to 4".

Should work fine I think.

Pretty sure this is how u work it out but dont hold me to it.

H x W x L X 2 or 3. Then plus 5% per light if air cooled. 15% if they are not.
20% for filter and 15% for every bend in duct.

Going by that yours should be fine

Cool, like it said it's still within reasonable temps as it is with no cooling other than a circulating fan, so I think anything would benefit really. For $55 bucks for the 8 incher, I don't think I can go wrong. Thanks, any more suggestions appreciated.

If you see its not being enough just get another one. 1 for each room it would be more then enough.

And for sound they are pretty loud ill admit you will most likely be able to hear it
