I've not been able to find any good threads about this. What is the possibility I could exaust my hot air from my grow room through the Plumbing Vent Pipe(s) sticking out of my roof? Anyway to tap into them? Does it stay empty and can I force air into it from my grow room and exaust the hot air into the sewer?

You can cut your stack pipe and install a ‘Y’ and vent up through it. I have never done it myself but I have told a number of people who needed a place to vent through that in their cases it was the best and most practical way to go.

The pipe that runs through your roof is a venting system so the drain portion of your plumbing will work. Without a venting system the drain part would not work. It does not handle waste and it does not connect to your sewer so you would not be venting into the sewer or into a septic tank. You would be venting up through your roof and into the air just as if you installed a dryer vent on the side of your home to vent through other than it would be high up.

That's true but you wouldn't have a conspicuous vent on a wall or roof. If you tap into the actual sewer pipe, the traps in your house would prevent the gases from coming in to your place.

Im based in the U.K. & Im just wondering how the houses in America (assuming you fellas reside there) are setup to allow for this type of ventilation. Can somebody please post photos, pics or a simple diagram of the connectings to enable whats at topic?

All houses will have a soil pipe from the toilet that vent outside they just might be outside the house or more likely boxed in and hidden.

Chimney is just as easy if you got one

Is this the pvc pip that runs up and out of the top of the roof? I was going to do that but didn't want to fuck anything up... I guess you could just cut a hole in it with a circular saw and seal it up after the ducting attaches to it...

p.s and def pics of this way would be great.

You'll also want a check valve also cause you dont want any gas's in the vents to come back and out through your access

What's a check valve? Sorry, I sure as fuck am not Ty Penigton or Bobby Vila
