How to get rid of the Smell and stay discreet
Cannabis has a strong scent / smell / aroma.
We growers love it ……. but our neighbours may get offended.
This is perhaps the #1 way for other people to find out about your new hobby.
People can smell it.
Thats why we use Carbon Air Filters.
Carbon air filters have activated charcoal in them.
Our used, stinky air flows though the carbon.
the carbon pulls out the stinky particles and the air is less smelly.
This method can filter up to about 95% of smell.
Some people even say their smell is totally gone.
This is a biological process.
To make this work well … you need to do it a certain way:
1. Move air slowly through them
The more time the carbon has to work, the better it will work.
That’s why you need fan speed control (as described on the previous page).
2. Use a good quality carbon filter
Don’t get the cheapest one becasue those don’t work.
If you like technical stuff, here is why. (skip this section if you like)
The better ones have pressed carbon in them.
The cheaper ones have just crushed charcoal.
3. Buy a big enough filter
They come in different lengths and diameters.
The bigger they are, the more they can filter.
The right size for your setup depends on your tent size.
Which Carbon Air Filter Size do I need?
| Tent Size | Carbon Air Filter Size |
|---|---|
| up to 3ft x 3ft / 1 meter x 1 meter | 4 – Inch (Amazon) |
| 4ft x 4ft / 1.20 meter x 1.20 meter | 6 – Inch (Amazon) |
| 6ft x 6ft | 8 – Inch (Amazon) |
| 8ft x 8ft | 10 – inch (Amazon) |
How to install the Carbon Air Filter?
It gets attached in front of the fan.
So the air is getting pulled though it.
Then there is a sock called over it which acts as a prefilter. It keeps dust from clogging up your filter.
You can also use the filter the other way around … by blowing the air into it.
But then you don’t have a pre-filter … and you need to build something.
How to use 2 Carbon Air Filters
You could use 2 carbon filters if your fan is strong enough.
Most fans can do this because Air is very … airy … meaning its easy to move around.
How long does a Carbon Air Filter last?
It depends. But after about 1 year you will start noticing more smell.
Then it’s time to change it.
