The ultimate Odour control thread

Odour control



So you want to know about odour control in the grow room.
This is just a list of the things you can use to control the odour.
You've got to realise before you start growing that your ganja is going to smell.

(If you live in a house with your parents, you best just wait it out till you get your own place. )

Here is a compiled list of helpful information to help you learn the knowledge that will help you to become a good grower.

The carbon filter.

Taken from wikipedia -

"Carbon filtering is a method of filtering that uses a piece of activated carbon to remove contaminants and impurities, utilizing chemical adsorption. Each piece of carbon is designed to provide a large section of surface area, in order to allow contaminants the most possible exposure to the filter media."

A carbon filter works by removing "the smell" from the air that passes through it.
Place a fan so that it's blowing (or pulling ) air through a carbon filter/scrubber.
It's that simple!
You can buy them from most good Hydroponic stores, as well as online. (eBay etc.)

The most common questions asked when anyone talks about a carbon filter is the following :
Can't i get it cheaper than in the store?

The answer is YES!

DIY Carbon filters

Below is a list of links to useful DIY carbon filters that people have made themselves.
Remember these are tried and tested and the people who have made them swear they work well for their needs.
( Just remember to take into account that your needs may be different. )

I will be updating this list as more are found/made.

ONA gel.





( Taken from ONA Gel odor neutralizer from 4 hydroponics.com by Growco Indoor Garden Supply. )

"Two odors can offset one another when they combine to form a bond. ONA's ingredients come from a blend of 32 essential oils and plant-derived compounds, that bond with and neutralize a wide array of pesky odors.

ONA odor neutralizer was originally developed for industrial applications to neutralize the strong odors in sewage treatment plants, rendering plants and chemical plants. If it can handle those conditions, think what it can do for you!"

ONA gel works by "killing" the smell.
( used in a grow room on a regular cycle. )





Hopefully this will stop a lot of questions asking the same things.
I started this to get the ball rolling.
I know a lot is missing.

What about UV Ozone generators?

Check the link in my last post. I don't know much about UV ozone generators so i can't say much on the subject.. i was hoping other people would be able to add to what i'd already collected.

That seems like an ok idea but isn't card ( which the box is made out of ) porous?

I always assumed it was.
But if it works. It works
