This was mainly just and idea I got from another forum. Someone was using the coal chimney as there exhaust outlet. There are other things vented through it, but they appear to have their own pipe leading out leaving opening around the piping. I haven't looked into detail on whether it's feasable in my situation, it was just something I got curious about. I would have asked on the other forum, but I am still unable to post over there even though I registered about a week ago.

I do own, so that is not a concern. If it is possible to use the chimney, I could always put a scrubber on if it becomes a smell issue. I know industrial stacks are much higher, but they also produce a much greater amount of whatever they are venting. I guess my next step is to do some further inspecting of how it is set up with everything else that is using it.
JaySin Reviewed by JaySin on . Venting through chimney In my house I have a huge utility room. In that utility room is an old brick chimney. I want to use this room for my grow. Do you think it would create a detectable smell outside if I were to vent my growroom up and out the chimney? I'm guessing it would exit at such a high elevation that it would not need any sort of scrubber for the smell. It's pretty much the same principal as at power plants. They don't want the smell/pollution detectable at ground level, so they put it way up in the Rating: 5
