My room is 10x10x8. The grow is in one corner about 3x3x8. Single 400 watt hps suplumented with 65 watt and 125 watt compact florescent. The room is used for storage so has furniture and boxes and other assorted stuff in it. The circulation in the room is not blocked by the stored stuff. Grow is normally 8 plants in DWC. I know that I need to exhaust the air in the room and perhaps increase intake. I am thinking of using a Dayton 265 cfm Exhaust Fan up high thru the exterior wall. The door on the room is not very air tight and I can leave it open during the day. Will this work, and will this exhaust most of the odor or do I need to add some type of carbon scrubber?

IMHO, unless you live all alone and never have ANY company, you need a carbon filter. Always-safety first. Don't smell.

I would recommend filtering your exhaust. Better safe than sorry. Read up on carbon filters, plenty of how to's or just order one. Your local hvac suppliers and/or some hardware stores will have fittings, adapters or hoses needed. I found a nice 6" rubber boot/sleeve in the plumbing section that worked great as an adapter to mount a 6" inline directly on top of a can filter, then I ran a length of 6" duct work off the exhaust side and it masked the noise well. The rubber boot was about 10" long, about a 1/4" thick and absorbed all vibrations from the fan. They do sell 6" wall mount dryer exhaust vents. Just looks like your drying clothes and has a cool flapper to keep critters out when its off.

nosmoke, it is totally your call.
With my luck, I'd have some dank stank just oozing out that sweet smell, not worrying about a soul and the fuggin marshall would get the wrong directions to someone's house and show up looking for the other lot down the road and BAM, I'm sweating bullets, ripping everything up as he drives off and not sleeping good weeks but that is my luck. I've tried to plan for the what ifs in my little piece of heaven in the back yard. I have my environment sealed and run an 8" 700cfm fan 24/7 through a carbon filter constantly recirculating the air.
If I were you, I would anyways so I never have to worry but that's just me nosmoke.
Peace

It is always good to clean the air even if you believe you don't need too. If you are going to do it you should do it correctly with the least possibilities of getting busted. Around here the charges are not severe, but the crappy thing is I would have to stop growing for a long while and that would just crush me. Do what you feel is best, but if I were you I would scrub the air. Who knows who is going to show up unannounced?

carbon scrubber on the exhaust, no smell, no worries
If you don't want to mess with a scrubber, you can simply get a nice ozone generator. Simply place the output tube near the intake of the dayton, and the ozone will destroy the odor molecules as the air exhausts outside.
Edit- Be careful when purchasing an ozone generator; there's a lot of knockoffs out there which are simple ionizers (ionizers do indeed generate ozone, but not enough to destroy odors). Get one from a reputable hydro store, and avoid ebay if possible.

Agreed.TheBEAK said:
I've seen carbon filters made in all sorts of shapes and configurations. You just want to make sure that your air passes through the carbon so it can absorb the smells. With a fan that small you could probably build yourself a wooden box around the fan with a slide out tray on the bottom. The tray can be made with a wood frame, fine mesh screen for a bottom, lay a piece of air filter on that and a 2" layer of carbon on top. Let her run, when you get near the end of your next harvest just step outside by the exhaust and see if you smell anything. Pre made filters can set you back 100,200 even $300. But it is so much cheaper than a lawyer and a felony.
