So this is my first grow and my question is I have a carbon filter in my tent and it’s setup with an ac infinity inline fan to exhaust when my humidity or temp gets to high. The issue I’m having is when the ac is on I have a little negative pressure in my tent. I know it’s not perfectly sealed and I’m ok with loosing a little co2 but that’s not what I’m worried about. What I want to know is how can/should I setup my carbon filter. My tent is in my laundry room and it has a door and the smell stops there. I want to have that room smell free if possible I just don’t know what’s the best way to do it. So I’m open to any tips. Thanks everyone
5x5 tent sealed using co2 and using dual hose ac. How can I control odor??

Dont really think smell free is possible if exhausting into a room. Maybe if you are running two filters, one recycling back into the tent 24/7 and another exhausting for temp control.
I am cheap, so i added a second dryer vent. A single carbon filter is effective enough for that. Exhausting into the room, the smell that got by the filter eventually caused a stink.

It isnt a sealed tent if you are exhausting anyhow. Kind of makes co2 pointless
So you would add a fan and filter to recirculate the tent air, and a fan And filter to recirculate the room? I dunno, with my setup i can vent when needed and not worry too much about CO2 cost, and haven't had an appreciable dip even with 1 output can. But there's little i have to do to maintain environment maybe due to climate and it probably doesn't apply here.
the stink is another thing and yeah ozone is heavy but a little ion genny would handle a small room and not require any tent or fan or anything changes to the setup. Not the $500 Dyson one but a cheapo $100 one.

Me personally, I run a closed system with co2 as well and all I have is an 8” fan/filter inside the tent. Works fine for me. Doesn’t completely kill the smell but enough. If it were an issue then I’d add another fan/filter outside the tent for me. If I try and vent for cooling/dehu in flower then my 20lb is empty in about 2.5 days. In a 4x8

Thats what i thought, but then he said " I have a carbon filter in my tent and it’s setup with an ac infinity inline fan to exhaust when my humidity or temp gets to high. " Maybe the OP can clarify

I double filter the tent air. Once when it is pulled through a filter in the tent and again when it passes through the filter in the trash can which is set at a higher speed so it has a "negative pressure" and filters all of the incoming air. Its sort of like a multi stage water filter system. Works PERFECTLY. You do have to run the tent fan at all times to keep negative pressure in the tent.... otherwise smell will leak out of the tent when its not running.

Hang your filter on the ceiling of the tent....

Ventilation is a vital factor in your plant growth. By supplying fresh air from outside your grow tent, you provide CO2 for your plants, driving their photosynthesis. Expelling the air inside will keep temperature and moisture build-up under control, preventing mold and mildew from inhibiting...

Inline scrubber inside the tent between ac/ducting off ac exhaust/carbon scrubber/can fan/ducting going out of tent and duct back to your trash can scrubber (i really like that cool idea) from there... should help that smell go away and you can add an inline uv light filter with the exhaust with some pvc conduit and some fittings to make it work but it would help as well or just an ozone gen running outside of the tent with this set up would eliminate much more of the left over smell
What I actually did was disconnected my exhaust side and let it just recirculating the air in the tent to scrub the air that way it can run constantly so there’s no duct work leaving my tent except the two ducts that go to the dual hose ac and now no smell in that room at all. Last night the fu##ing hose popped off the exhaust side of the ac and I woke up and my tent was 92* so I fixed that with some aluminum duct tape now it’s 78*. Thanks for the tips. I have a lot of ideas I want to change inside the tent after this grow to make things much nicer and prettier

I bought this off Ebay for less than $100. It releases plasma into the air to neutralise odour. I don't even have it in my grow room but outside at the door. Maybe it gives you cancer and the high pitch squeal it emits is the most annoying sound on the planet...but it works, works really really well.
I switched my tent layout to make better use of Co2 bags. Works well too and my ppm is steady 800, the bags are fresh so they're still getting started.
