Carbon filter/scrubber - New grower

[dangargrower]

Ok so going to be doing a grow of 6 plants, in a tent that is 1mx1mx2m.

however i am a bit confused on which size of extractor, inline, and carbon filter i should be using.

there are 4" setups, and 5" setups and obviously much bigger ones.

which one should i go for to ensure smell is 100% gone

thank you.

I would suggest 6".

I am growing in a 3' x 2' x 4' cabinet and only need a 4" to ventilate, but all the air cooled hoods I'm looking at (possibly upgrading to different lighting) have 6" connectors.

If I had started with 6", I wouldn't have to upgrade later
