I had the same problem with my portable ac, it was venting the smell outside BAD. I ended up running the ac exhaust into a barrel I cut a hole in the side of to pipe the ac exhaust into, then I cut a hole the lid the size of my carbon filter flange and ran screws thru the lid into the filter. I them mounted another in line fan to the filter and vent hose to outside. That fixed my issues as the ac was where my smell came from. The other filter in the grow room was being bypassed by the ac. I’ll try to post a pic in a few minutes.

The ac exhaust is very hot which makes the smell even worse, this fixed my smell.

Howdy all

I know there are a ton of threads on this topic but none that are specific to my questions/concerns...

I'm rounding out week 7 of flower and the ladies have really started to stink the last several days and I suspect it will only get worse between now and the end of drying.

I have an exhaust fan hooked up to a carbon filter as well as an additional fan and carbon filter in the middle of my lung room...all that, after 2 carbon filters, and it still smells. I've noticed that some days it's worse than other days...why? The smell is about 95% contained to the basement although I wish it was 100% contained within the tent. Of the remaining 5%, I would say that 4% is leaking throughout my house and 1% is getting to the outside...you'll get an occasional whiff of it before it disappears. I have a portable AC unit hooked up and when that thing cranks on, the outside smells pretty bad if you are in front of the AC vent. Does anyone have a hack around this so the AC won't allow the smell to leave the house?

Is it safe to assume that with good, stinky bud, starting around week 7 things really start to stink and it only gets worse before it gets bagged? Or will the stank lower at some point between now and then? Is it more common for the ladies to smell with lights on or off, or does it not matter? I ask this because I might have my lights turn on at a different time to help combat this. Other than a carbon filter in lung room and one hooked to the exhaust fan in the tent, I also have baking soda on plates throughout the lung room. Does anyone have any other hacks they can share?

I'm thinking in the next run I'll hook up an exhaust fan to my lung room (pushing air outside) and connect that to a carbon filter. I figured if the already filtered air is being expelled constantly, and through a carbon filter, then I should take care of the smell, right? While also dealing with most of my humidity issues...?

Keep your extractor fan on high 24/7 if you want to limit smell. Once it slows down the smell leaks out more

Just throwing this out there. I bought a carbon filter and exhaust on my first grow. I was still smelling it outside it was quite strong. It turns out what I was smelling was someone else’s grow.

I smelled a faint tomato smell in the morning years ago when I would go to work early in the morning, didnt think anything of it. A few months later I was talking with my neighbor about I have know clue and for some reason I remember telling “yeah I can smell someone growing around here and thought it was tomatoes”. Nothing was said after that for a few months. One day I was having a beer and smoking a bowl with this guy and he says “hey dude, you’re cool, and I felt really bad about lying to you, here come and check this out” two houses down lol!

I asked him about the grow he had going on in the 90s that he never told anyone he was doing it but everyone knew

Yo. So how does this work when the AC isn’t running? I assumed there would be too much negative pressure in the barrel whether the AC was running or not…?
