Recently started using a Flower Carbon Filter since I no longer need a big fan to cool an HPS. Replaceable carbon filter block fits a 120mm case fan and seems to be doing a decent enough job keeping smells down outside my tent. Once I open the tent flap the aroma really hits me.

Wow just saw ths huge jambled 3 am drunk speech I made sorry if it's hard to read Ill either fix it or delete my stupidly by morning. Great forums you guys got hoping to share my experience and grow with you guys as a Terp hunter!!!! My experience with 2 micro grows, as long as the grow room is closed with the window open always ( even in -30 celsius) the rest of the house is fine and you get no smell unless I quickly open the door for a sec. By week 4 I thought it cant get any worse, it smells like candy, skunk, and berries so pungent i could taste it in the air. Week 5 came, house is still okay because it's winter and everyone leaves their windows closed. This was the main reason I felt okay with no carbon filter was because no one opens their windows when we have -40 winters in Canada. In week 6-8 it finally hit me, I was down the street.... walking back home and I got a big which of my purple beauty a street down! My window was on the other side of my house as well!!! That's when it hit me, i was ignorant for not listening even though some told me 1-2 plants don't smell that bad, it's a about the pheno! Some are like candy skunks that half your neighborhood would smell only from 2 plants in 3 gallon pots grown with a amazing cheap 100 watt LED. Its late sorry if this is long I'm a little innepreaited, cheers! I'll introduce myself tomorrow and show you the beauties (one is hanging, first indoor was a success!)

Neighbor just gave me a Friendly heads up. As soon as I get out of my car in the driveway I smell it from all the way in the backyard in my pool shed. I have a portable AC and a window unit with no filter at all. Will a five or 6 inch carbon in-line filter do the trick. I’m not worried about the little tiny window unit because that is in the window and my portable AC is in the middle of the space so that is with sucking up all the smell

If it’s really humid carbon filter won’t work hardly at all
How big is your grow
If it’s a closet or a small shed a 6 inch should be plenty

A super cheap way my buddy always masked the smell was connecting an in-line fan to vent hose and he’d take 8 inches of 4in pvc, drill holes, fill with charcoal and it kept smell down. He’d also put dryer sheets on the outgoing air vent. He did that for years
 
DOes anyone know if its possible to join up to a bathroom duct to exhaust? Im setting up my grow tent in my master bathroom and there is a bathroom fan in there already. I could go into the attic and attach a Y onto it but im not sure how to make sure it doesnt just blow back into the bathroom fan lol. The windows are the type that tilt out, with winter coming in not sure about how to vent out them.

Your bathroom exhaust fan is most likely 3 inch or 4 inch and that probably won’t be enough to exhaust the heat and or all of the smell. You could add an exhaust and terminate it at the roof with a roof jack. Just an ides.

Thanks, I rent so that is out of the question.

I think I will have to build an insulated panel to block the window and go through there.

Edit: So what's the worst that can happen? some air comes back into the bathroom? I'm going to have the carbon filter on it so its not that big of a deal, and i'm in Canada so its legal.
I'm worried about damaging the window leaving it open to the snow and cold all winter probably isn't going to be great for it.

Hey everyone, I am trying to accomplish a odorless grow tent (my tent is 24x24x48 with one plant at a time or three autos. my question/s is, are these filters ok/good/bad and if I use 2 of them, can I meet this goal?

I understand that whenI open the tent it will let smell out but I am going for no odor at all when its closed. moving into a townhouse or a house in MN and need to keep it 100% stealth from neighbors/family/maintenance people/etc.

I used those and they're solid. Make sure you have a decent fan. You only need one for a 2x2.

I have a 5 x 10 grow tent in basement. 6 in carbon filter and fan. Ive never had issues with smell before. This is a new filter. I just started flowering and I can smell em upstairs. Think I just got a bad filter or whats up?

I think my problem is humidity. Stopped running dehumidifier a couple weeks ago in basement and didn't connect two and two together. Carbon filters won't work in high humidity right? Gotta be below 60 I believe

yeah something like that, I run an 8x39 for exhaust and an 10x39 for scrubing in my 5x10 and you could take someone in there with a blind fold and they wouldnt smell shit
6in would cut my costs quite a bit if it works

Wow ya I think you should stay with what you got ha! 6 in is prob too small, good thing I don't have close neighbors :p but I've only ever ran 6 in and never had issues, but I kept humidity at like 40-50. Right now it's 70.

Idk if it has been mentioned, but has anybody used a hydroxyl generator during drying? I have access to one, but I don’t want it to pull all the smell out of my bud or some shit.

I’m running a 4in carbon filter in my 3x3x5. Some days I swear I smell lil something other days no. That being said you get used too the smell and when fresh noses come in is the true test
I think I’m gonna buy one more filter to put on exhaust side of fan or is that not a good idea?
