Finally a New Grow Area

[Bluey]

I need to run a carbon filter here and create slight negative pressure in my flower room during stank phase. The smell has gotten completely out of hand here and people are noticing it driving down my road if they have their window down, and thsts quite some distance from my house. I get a few comments and most know exactly what it is. That's a big concern.

I can't really do it properly though with my current setup as the main AC draws some air from the room for the heat exchanger and I have to vent that outside unfiltered and with extra heat, which likely makes the stank even worse. I need a big split system to solve that...

My old tent was a DIY and when the fan came on the sides got sucked in, so there was a lot of negative pressure for the carbon filter to be most effective.

Bluey maybe you could construct a small box in the middle of the exhaust run and mount an ozone generator in there. That would eliminate the smell... Your only looking for a small unit, but not to small lots of air flow moving through there. Some people use the Ozone generating UV lights for AC duct and some use a small ozone plate with fan..Two approach guess it depends on the situation.

just a thought

Ozone generators are something I know zero about.

The AC blows out a lot of air through a 4" duct that's quite short. I could divert it into the sewer.....hmm. worth a test.
