What I want to know is, what do all of you use for odor control and how well is it working out for you?

**Note** you can select more then one option in the poll.

If you can, please give a small description of your set up (i.e. number of plants, strain, type of ventilation,, type/watts of light.) As well as pro’s and con’s of your odor control system and what you’d do different if you could.

I’m all ears.

For myself I use a crappy Neg. ion generator/ozone gen combo unit for my 5 plants under a 400w HPS. The Ozone gen was working great until my daughter and I both developed lung problems (like excessive coughing, sore throat, chest pains, & headaches) (BTW I grow in my bedroom closet, daughter is in the next room over wife never had any problems). Since switching over to Neg Ion not only has our breathing problems vanished but the smell is now more noticeable. I'm using glade plug-in's to supplement the neg ion gen for now.

As far as ozone goes I’ll never use it in my grow room again. It is really best left for your exhaust vent. Since I vent into my apartment and not outside I need to find a better method.

I'm not sure what you can do less then installing an expensive air scrubber unit. I do not think you can completely eliminate the odor any other way without the extreme measures you wisely eliminated. O3 is dangerous. I think a unit could be created somewhat cheaply, but I have never designed one. Seen many however, basically carbon ventilation filters with treated water (water-bleach) running over them while the foul air is passed through 1-3 filters. Following the passage of air through the wet filter, a demister is sometimes is installed to lower the suspended water concentration but not always. Basically a reservoir and pump that mists the vertical filers in a sealed enclosure where foul air must pass through the filter. Water drains back to res.

It works great where I have seen the technology used. For example, at a wastewater treatment facility influent structure, the air is very foul (very) and is treated and expelled with almost no odor. For this to work this well, a homemade one should handle the plant odor as well as cool the air expelled from the room.

I would really try and find a way to vent to atmosphere. I use two fans in series on the same line to overcome the CFM/distance issue. One fan is off when dark to maintain a constant negative pressure in the room.

Also, unless you are at the north pool, the excess heat must require your AC to crank.

Nothing but a strong exhaust fan. All odors are exhausted straight up out of the roof high into the sky never to be smelled. Atleast that's been working. I'm thinking this time around I might need a small ozone generator though.

I'm using a carbon filter and have the exhaust fan blowing through that. I also have one of those little 'mountain breeze' negative ionisers in the room outside my garden. I'm not sure that has much more than a placebo effect, though. The carbon filter also has the advantage of acting as a silencer.

It seems to be working pretty well. I can't smell anything at all and my garden's just in a cupboard in the living room. Plants are fairly smelly at the mo, but they're going to get much smellier (i hope).

My gf hasn't moaned either yet and she had a good old whinge about the pong on my last grow, when I had no odour control at all. That got pretty whiffy. She was probably right, though, but I'm not going to tell her that

cheers

I use the ThunderBolt SkunkBuster Ozone Generator.
Works pretty damn good. It runs 4 times a day.

First, a little background. I have a 4' wide, 20" deep, 6' tall cabinet inside of a closet with sliding doors. The grow chamber is 5' tall and there is a sealed off shelf at the top. There is a passive intake on the lower right side of the cabinet, and a fan draws air out of the grow chamber into the shelf area at the top left. The exhaust travels the length of the cabinet and exits on the top right. A carboard "duct" then chanels the exhaust to the left side of the cabinet (on the outside). The doors of the closet are left cracked about 6" on each side.

Odor control:

1. Strains. Two NL (Nirvana "pure indica" variety) and three Cindy 99's (the F2 available on Seeds Direct). These are relatively low odor plants. The two NL's are vastly different phenotypes; one smells a bit skunky at times and looks vaguely sativa for an NL, while the other barely smells at all (and has the broadest leaves you've ever seen). The Cindy's have a slightly fruity-sweet odor, but don't really smell obviously like weed.

2. Activated carbon furnace filter (available at a hardware store for about $8) in the exhaust shelf.

3. Holmes air purifier (available at Wal-Mart for about $30) with hepa/carbon filtration and ionizer. This sits at the end of the cardboard duct.

4. Sharper Image mini-size ionizer sitting on top of the cabinet.

5. Baking soda. Two sitting among the plants inside the cabinet and one in the exhaust system.

6. Renuzit odor-absorbing gel pod (available at the grocery store for a few bucks). This is sitting in the room a few feet away from the closet.

7. Glade plug-in in the apartment's living room (just to make sure anything leaking out of the back room is covered).

This may seem like odor-control overkill, but I've figured that odor is my primary risk for getting pinched Interestingly, even this level of odor security doesn't always eliminate absolutely all traces of weed smell in the apartment. I find the plants can overpower my myriad levels of security after a feeding/watering. The smell is faint and probably wouldn't be noticed by a "civilian", but I'm completely paranoid and end up spending about 5 minutes every morning sniffing the air to catch a whiff of that tell-tale scent.

Did I mention, I just started flowering yesterday; this smell has been during veg?

Glade plugins- Hawaiian Breeze?
Lighting: Varies 400-1000hps/mh
Strain(s):Adv. mix, C99
Bedroom closet, passive ventilation(window wide open), oscillating fan.
A few "plug-ins", strategically placed around the Apt., does an adequate job. I get a couple of visits/year from the Landlord, and I'm still here.<Knocking on wood>
