smell? help please!

So I've been growing for over a year now and never really worried about the smell. But I am starting to smell it as soon as I step out of my car and definitely any were around the front door. Are carbon filters really a good investment? Looks like it's about my only option on smell controll.

Yes, they are. Phresh is fairly widely accepted as a great filter, match it up to an appropriately powerful in line fan.

I have a fan coming off my thousand watt. And a fan coming out of my tent. They both meet up and go into the attic. Should I connect it to the end of that like up in the attic? Or just get a seprate fan all together for the fiter?

Usually its best to put the filter on the intake side.

So on the open end of my light?

Yes, but you might want to toss a piece of duct (flex or solid) between the light and the filter. Some folks dont even exhaust for smell, they just scrub and circulate inside the tent.

Well my 1000watt isent in a tent I have my flowering in an open room then my veg in a tent in that open room. It weird the smell is stronger outside the house than in the house

The instructions to my filter says it can have air flow either way. From what I understand they work best with air pulled through them and negative pressure in the tent. In your case I would put the filter in front of the fan coming out of your tent and pull outside tent air through hood so that all smelly air goes through the carbon filter. You might not have to run a carbon if you run it to the chimney, I've heard that helps it carry away further from the home.

edit: I didn't picture your setup quite right at first, might be easiest to just stick a carbon filter in the attic and the end of the ducting or another fan with carbon filter to circulate attic air, or like orbo said.

I just bought another fan/filter today that I just stood up on the ground to use in along with my scrubbed exhaust. It seems to help.

I'd be in prison If I didn't have one. Lol

I don't have it set up in a tent and I don't belive I have a chimney

Do you think it's stronger outside because I vent into the attic?

If you can swing it $$ wise, maybe just try adding a 4" inline fan and filter in the flower room...to scrub the air before it gets exhausted. This way no real changes to your overall design. Just some cleaner air being exhausted into your attic. Like what @fjbudboy suggested he did in post #9

probably humidity holding it down

Yeah, that air would be leaving through the soffit/fascia or other vents which all lead outside.

I was looking at this 260$ fan and scrubber combo it's an 8in 720cfm. Do you think I could put it sucking threw the filter blowing into my attic?

Sure, that would do the job rather nicely

If I have it completely seprate from my exhaust system will it clean the air befor it sux threw the exaust?

To a certain degree, yes. Hard to say what will end up going into the attic until you try it

what size fan do you use now to pull/push air to the attic?
