Ventilation & Smell

Ok, I have read few threads here regarding ventilation and the smell of the crops. It sounds like the smell of the crop is VERY STRONG (if it can be smelled even after it was passed through the sewage lines) is it really very very strong or perhaps strong for urban / congested areas?

If I put a bathroom ventilation fan and let it throw from the roof using a PVC pipes do you think that my neighbors (who lives aprx 50 feet away from my house) will be able to smell?

FYI: My roof is about 9' high and I am not concerned with the sound of Ventilation fan !!

Any ideas or suggestions will be highly appreciated. Thanks in advance.

It depends on the strain. But yes they do stink up, im having problems myself. Your plan sounds like it would work 50.

Newtothis, what you propose is exactly what I do. (the bathroom fan) However I came across this odor neutralizing machine that you make yourself, on the cheap. I may make it before summer. Here are the plans for it:

You will need:
1. A five gallon bucket
2. A "muffin" fan, or a round fan of some sort that has the motor built into the compact frame of the fan.
3. A drill
4. A one pound container of Soil Moist, which is a water absorbing crystal. You can find it at almost all nurseries and gorw shops.
5. ONA, or Odor Neutralizing Agent. You can get it at most grow shops or "baby" shops for new mommies.
6. A 5 gallong bucket lid, which may be optional.
Get yourself a muffin fan, or a Durex brand or Holmes brand circular fan with base. They are very common at Wal-Mart and can usually be bought for less than $8 US. The reason you should get this brand of fan is because after you have removed the base, it fits perfectly into a five gallon bucket.

Step 2.
Using a flat screwdrive, pry of the nubs on the base and remove the screws.

Step 3.
Remove the fan from the base. Keep all the parts in case you might want the fan again someday.

Step 4.
Place the fan into the five gallon bucket, frontside up. If you bought the holmes brand fan, it will fit VERY snugly. You don't even have to secure it in place.
(If it is smaller than the opening, then cut a hole, smaller than the diameter of the fan, into the bucket lid. Use some floral wire and secure the fan to the lid so that you can place the lid onto the bucket.)

Step 5.
Drill about 8 or 10 holes around the bucket.

Step 6.
Remove the fan/lid and put about 9 cups of water into the bucket. Then put about 1 cup of the ONA into the bucket and mix it up. Be careful, it can smell pretty strong at first.

Step 7.
Put about a cup or two of the soil moist into the bucket. Make sure that all of the liqued is absorbed. You don't have to use alot! The crystals expand to about 50 times their size.

Step 8.
Set the fan on the lowest setting and put it back on the bucket. Plug it in and put it somewhere in the corner of your grow room. I don't actually have mine in the closet itself...
You will notice a difference in about 5 minutes!
You may need to tweak it for your own grow room, but that's the basic design. Thanks!

I'd say that that a cup of ONA, with the other parts water, lasts me about 4 weeks or so.

Dude! you must be smoking some good shit!! LOL

That is ingenious.... I really like this idea and I think I might try it. When you do get a chance to work on this project please dont forget to take pics and or make a video so other beginners can benefit from it .... I'd try to do the same if my seeds come in any time soon.

Thanks again for your help and happy growing.

Do you have any pictures of that? I'm about ready to flower and have yet to come up with anything that will help with the smell.

None of my neighbors have said a thing about the smell. And I have never noticed anything when I have been outside either. But I vented out by a lot of shrubs and trees too. I mean flowering shrubs and fruit trees. Wondering how much mother nature has to do with covering or masking the smell?
