I'm not sure if this is a new idea or if its just a dumb one, but here it goes... I was working on a job site when I realized that there isn't a trap on the sewer/septic main lines that come into a house. Seeing as the sewer lines on all buildings also vent through the roof in an airproof run, I was thinking that it could be possible to vent a graden into the sewer in the basement. I think it would work perfectly if you are already running an exhaust fan 24/7. Constant airflow from your garden into the sewer line would prevent sewer gas from coming back in, no? And all smell would be either sent down the pipes or ventined above the roof line. Edited post after I added a pic in my gallery of what i was thinking...

Started looking into this idea more. the water in the traps of the toilets and sinks of your house should keep the room air from exhausting back into your house at any point. And most sewer lines are already 4" pipe, so this might be worth tryng as an exhaust...

Sounds doable..

I would want some sort of 1 way flap that only lets air/sewage go out of room and into sewer.
Kinda like a one way air tight doggie door.

So for if some reason your fans (exhaust) stopped working you would not have sewer essence airreating your grow...
Or if worst case scenario the sewer backed up...

Happy growing

There was a tutorial for this on OG back in the day. Only concern to overcome is combustability of gases. If you bypass this problem then your money but every situation is differnt depending on age of sewer line and general upkeep of said sewer system.
