The Smell? What exactly should I expect?

[OkinKun]

I know that strain will determine a good part of what the end smell will be (strength and aroma wise)...

But for a 4 plant (less after sexing) grow, in a concrete/stone basement, with no direct air opening (yet most likely not air tight unless I go seal crazy with plastic garbage bags and duct tape.) to the outside anywhere near that area of the basement... How bad will the smell be? Will it be noticeable from outside the house?
I've never experienced a grow before, so I have no idea of what to expect, smell wise.

Would planting flowers outside around the house help to mask the smell maybe?

Currently I don't have much in the way of smell eliminators, Will I really have to worry about that? I can't spend much for some fancy air filter... Cheap alternatives?

[CaliGrower]

Buy ONA and a ionic air filter from Ebay. Both are cheap and will do the trick of eliminating odors.

Like you said, smell is mainly determined with genetics, but there are various things that can decrease and increase this also. Most of the smell comes out during flower, keeping the heat down in the growroom should reduce this a good bit, and good airflow is a must in a good grow, getting fresh air in and old used up air out, so you might want to think about getting some sort of venting system down there for more reasons just then smell. With just 4 plants i couldnt imagine the smell being noticeable at all especialy through a brick wall basement though if that eases your worries any.

Yeah thanks, it does.

Yeah, I'm gonna put a fan down there, to circulate the air. The other half of the basement (somewhat separated, but still open air access from a short distance), has it's windows open, so I'm not too worried about Fresh air getting in... I'll also try to supply some CO2 at some point here and there.

The plants are going to stink up your house by the time they are ready to flower, and by the time they are done flowering, you will be able to smell them outside your house easily.

That is unless your safe, odor control is #1 priority for not getting caught. Get some odor neutralizer, like ONA from your local hydroponics store. Also invest in an AirSok, and strongly consider getting a Ozone Generator (although not required if you have an airsok and some ONA... ONA may do it by sitself, but why chance it?)

Oh and don't think I'm exaggerating, funny smells get people talking pretty quickly, and they can call the cops pretty quick. That'll put you in a bad situation.

Again, depends on the strain. I live in a 4 bedroom apartment, and I only know one of my roommates. We have a small op (3-4 plants in each) going on in both of our closets. We chose low oder strains. We don't do ANYTHING for the smell except for air out the room occasionally, and our roommates are still clueless...3 1/2 months later. If you're really worried, this is the cheapest and easiest thing to do for a small op like yours. Go buy a bag of charcoal, a bucket and a small fan. Drill holes in the bottom of the bucket and crush up the charcoal. Stick the charcoal in the bottom of the bucket and place the fan so the air is blowing INTO the bucket. This will pull all the air from the room, pass it through the activated charcoal and the air will filter back out through the holes in the bottom.

charcoal will not get rid of smell, you probably are talking about activated carbon right? don't want to mix those 2 up.

Security is important to marijuana growers, and odors can lead the police straight to your grow room. There are a number of 'odor solutions' out there, but they can be quite costly. Here is a simple method you can use to build your own carbon filter. It will take you about half an hour to construct it, and it will cost $20 to $30 dollars.

Aside from its main advantage of being ultra cheap, this method is also very versatile. It utilizes the exact same activated carbon filters that are used in professional air cleaners, without paying the huge prices. It can be adapted to practically any ventilation system. You do not need any crazy tools to build this - anyone can do it.

For supplies, everything is easily available at a store like Home Depot. You will need the following:

1 activated carbon filter - ( found near humidifiers, air, and hepa filters )
1 small roll of aluminum screen
1 four inch ventilation end-cap
1 four inch duct connector piece
1 roll of duct tape

No tools are required. A pair of scissors and a measuring tape are all you need.

The carbon filter I purchased is a 'universal' replacement filter for HoneyWell air purifiers. Since I didn't pay the hefty price for a professional unit, I will cut this to size. It was originally 16" high and about 48" long, so I cut it right down the middle. When the first filter is expired, I will have a replacement ready to go.

<v:shape id=_x0000_i1043 style="WIDTH: 479.25pt; HEIGHT: 362.25pt" alt="http://pictures.marijuana.com/gallery/data-stuff/30bb3825e8f631cc6075c0f87bb4978c/513_p5699.jpeg" type="#_x0000_t75"><v:imagedata o:href="http://pictures.marijuana.com/gallery/data-stuff/30bb3825e8f631cc6075c0f87bb4978c/513_p5699.jpeg" src="file:///C:\DOCUME~1\JUNK-G~1\LOCALS~1\Temp\msohtml1\03\clip_image014.jpg"></v:imagedata></v:shape>

The next step is to cut your aluminum screen to size. I chose aluminum because it will be strong, and will still allow good air-flow. You could substitute chicken mesh or something similar. Since my (cut) carbon filter is 8" high, the aluminum will be cut to 12". The carbon filter will go in the middle 8" of this screen, with 2" coming out of each end to connect to the duct pieces.

Now we will attach the aluminum screen to the duct pieces, with duct tape. (This might be the first time you have actually used duct tape on ducts!) Do your best to keep it straight as possible.

It will seem a bit flimsy at the beginning. Continue to wrap the aluminum screen around and around, taping it every few inches. You want it to hold firm.

After a few wraps it will be fairly sturdy, and able to hold its own weight. However, don't drive your truck over it! Treat her nice and gentle like a Christian schoolgirl.

<v:shape id=_x0000_i1047 style="WIDTH: 479.25pt; HEIGHT: 362.25pt" alt="http://pictures.marijuana.com/gallery/data-stuff/30bb3825e8f631cc6075c0f87bb4978c/513_p5703.jpeg" type="#_x0000_t75"><v:imagedata o:href="http://pictures.marijuana.com/gallery/data-stuff/30bb3825e8f631cc6075c0f87bb4978c/513_p5703.jpeg" src="file:///C:\DOCUME~1\JUNK-G~1\LOCALS~1\Temp\msohtml1\03\clip_image018.jpg"></v:imagedata></v:shape>

The ends of your screen may have little strands of metal poking out, threatening to impale you. Add some more duct tape to cover this up and to finalize the DIY carbon filter. Soon it will be done.

<v:shape id=_x0000_i1048 style="WIDTH: 339pt; HEIGHT: 450pt" alt="http://pictures.marijuana.com/gallery/data-stuff/30bb3825e8f631cc6075c0f87bb4978c/513_p5704.jpeg" type="#_x0000_t75"><v:imagedata o:href="http://pictures.marijuana.com/gallery/data-stuff/30bb3825e8f631cc6075c0f87bb4978c/513_p5704.jpeg" src="file:///C:\DOCUME~1\JUNK-G~1\LOCALS~1\Temp\msohtml1\03\clip_image019.jpg"></v:imagedata></v:shape>

Now it is time to wrap the activated carbon filter onto our device. Conveniently, the filter I bought came with a couple of velcro straps, so I used them to hold it on. This will be convenient to replace when the activated carbon is expired.

<v:shape id=_x0000_i1049 style="WIDTH: 479.25pt; HEIGHT: 362.25pt" alt="http://pictures.marijuana.com/gallery/data-stuff/30bb3825e8f631cc6075c0f87bb4978c/513_p5705.jpeg" type="#_x0000_t75"><v:imagedata o:href="http://pictures.marijuana.com/gallery/data-stuff/30bb3825e8f631cc6075c0f87bb4978c/513_p5705.jpeg" src="file:///C:\DOCUME~1\JUNK-G~1\LOCALS~1\Temp\msohtml1\03\clip_image020.jpg"></v:imagedata></v:shape>

After she's all sealed up, throw on a bit more duct tape around the edges of the carbon filter, to seal up any gaps. Only tape over the edges, because you want the air to flow as easily as possible. Air does not flow through duct tape. Here is the finished product.

<v:shape id=_x0000_i1050 style="WIDTH: 479.25pt; HEIGHT: 362.25pt" alt="http://pictures.marijuana.com/gallery/data-stuff/30bb3825e8f631cc6075c0f87bb4978c/513_p5706.jpeg" type="#_x0000_t75"><v:imagedata o:href="http://pictures.marijuana.com/gallery/data-stuff/30bb3825e8f631cc6075c0f87bb4978c/513_p5706.jpeg" src="file:///C:\DOCUME~1\JUNK-G~1\LOCALS~1\Temp\msohtml1\03\clip_image021.jpg"></v:imagedata></v:shape>

Time to hook her up to the grow room exhaust! In this case, it is being hooked to a 4" square duct. (That is why I used a 4" round to 4" square connector piece. You may need a different piece to suit your ventilation setup, but a million sizes are available.) Just slide her onto the vent, and tape it down nice and sturdy. Duct tape is your reliable grey friend.

<v:shape id=_x0000_i1051 style="WIDTH: 339pt; HEIGHT: 450pt" alt="http://pictures.marijuana.com/gallery/data-stuff/30bb3825e8f631cc6075c0f87bb4978c/513_p5707.jpeg" type="#_x0000_t75"><v:imagedata o:href="http://pictures.marijuana.com/gallery/data-stuff/30bb3825e8f631cc6075c0f87bb4978c/513_p5707.jpeg" src="file:///C:\DOCUME~1\JUNK-G~1\LOCALS~1\Temp\msohtml1\03\clip_image022.jpg"></v:imagedata></v:shape>

After she is attached and fire up, things are looking good. It is working nice, hooked to a 60 CFM fan, and you can feel the air flowing out of it lightly. The fan was not slowed down too much, but obviously a carbon filter will add some back-pressure to your vents. I haven't tried this with a slower blower (under 60 CFM), but 60 CFM is not a lot.

I just hooked this up today, so I don't know how often I will have to replace the carbon filter. The box the filter came in says to replace every two or three months. It does seem to make a difference though. Outside the grow room does not stink like a skunk anymore. There is almost no smell at all, except the faint odor of duct tape adhesive. I'm sure that will go away after a few hours.

Using this method, everyone can now build their own activated carbon filter. Its quite easy, and you can build it any size you need, to fit any grow room and any type of duct. Could it get any better than that?<o></o>

posting a link to the above thread would have been a better idea, so it doesn't clutter this one. and if i remember correctly that about DIY thread has pictures to help with the construction, which aren't shown in your copy/paste.

4 plants won't smell to bad even if it is ak47 or something real potent. As long as the room you have it in is closed with a window open or ventilation that should be enough.
