What size room do you have ?

Grow your own medicine.

2.4 x1.2 tent, surely the control unit regulates the fans to maintain the correct pressure.. Or surely I can run my intake at full and my extract at half or whatever combination turns out to be just right, isn’t that one of main points of the fan control unit?

What formula did you use to get to those figures dude?

Can't read that dude.

Ah sorry man having troubles uploading full size, can’t post link as it’s from eBay but I think I’m aloud to say if you search rvk fan in eBay and loot at the item description it has a full list of fans from 4inch to 10inch and all the different airflow rates

**Dirty_badger** · 06-02-18, 02:23 AM

I've got the 6" rvk A1 428m3/hr as my intake and the 8" rvk L1 1008m3/hr as my extract. There's a fair but of ducting on the exhaust end of the extract to I'm guessing it'll be reduced by around 10-15% and they work perfectly together.

If I was you I'd get a bigger intake or add a passive to ensure you're getting enough air in the groom.

Does another 4 inch passive sound ok?
