Hoping someone can clarify a few things as think I've done to much reading on it lol

I've calculated my grow room needs approx 180cfm. I will be adding for heat generated by LED'S, warmer weather and duct fan turns etc so will be going a little bigger prob nearer 300cfm.

Ideally i want the air exchanged every 1 to 2 minutes.

I already have the AC Infinity 67 controller so fan wise it will be definitely be an AC Infinity.

So the AC S6 fan has a CFM of 402cfm, perfectly adequate but I'm thinking that's full blast and I'm worried about the noise.


Would the AC S8 you think at 807CFM running slower be quieter?

I definitely need to get rid of the smell as much as poss and as the grow is in a loft it can get warm in the summer.

Last question is matching up the fan and filter CFM. I understand how to do that but see my confusion below.

If i go AC infinity S6 fan (402cfm) and rhino pro 6inch filter 150 x 600mm at 529cfm I'm worried about running fan fast and noisy to get enough air through the carbon to sort smells.

If I go AC s8 fan 807cfm the biggest rhino 8 inch Pro filter is only 662cfm. I've read the filter should be a larger cfm than the fan so air is pulled though is slower and smells dealt with better.


With the above I've also read lol that i can run a 6inch fan with an 8 inch carbon filter which helps with the noise but also the smell.

Is that correct?

Any advice would be appreciated on any other 8 inch filter that works well for smells and my setup.

TIA. I'm a novice and first grow but my ladies are doing well and want to keep them that way.

Go with 8 and run it slower so it matches the cfm if the filter.

Humidity will be your biggest efficiency challenge imo
