Carbon Filter vs Ozone

[Toomp]

I cant Understand the Carbon Filter.
I cant figure what or how the carbon filter works? I read and look at pics but I cant understand it. This Lack of understanding could also have something to do with myself not understanding air intake
Is it like a fan is attached to duct leading outside pulling air in, Then that duct are attached to the lights to cool the lights. Then ran out the grow room where The carbon Filter is met with another fan Blowing out of the grow room?
If this may be the case then how does this combat the smell leaking through small faults in the structure of the environment if it is just a can attached to a duct leading outside of the room?


would it be more practical to use a Ozone Generator instead?

Please assist Best you can

Ozone can eliminate the smell of your buds if you use too much. How much is too much? You can do some experimenting if you like, I don't know.

A carbon filter works by passing air over the surface of the carbon and the aromatic compounds (smells) bind resulting in altered chemical composition. If the air passes through the carbon filter and exits the grow structure, that creates a negative pressure in the grow structure, assuming there are no intake fans blowing air into the structure at a higher rate than the air exiting. When the grow structure has a negative pressure, any crack or "fault" in the structure would result in air flowing into the structure through those cracks.

There are numerous ways to set up a carbon filter, the main points in making it effective being that all air exiting the grow structure passes across or through a layer of carbon and that the humidity be below 60%. Carbon filters don't work well at higher humidity levels.

Hope that helps clear things up.

Sam's right, humidity is what kills carbon. When it absorbs water instead of odors it's pretty much dead.

I use both, but for a truly sealed room you should be pulling in outside air to cool your hoods, and then exhaust it back outside so it never touches your room air (or picks up smells. Carbon filters are then used just as a scrubber, treating and re-treating the same air over and over.

Ozone is good for air locks, attics and basements, if you happen to be venting air/exhaust into those spaces and smell is a concern. Takes about 30 seconds of mixing for Ozone to kill odors.

The Scrubber Is placed where? Reason why I asked I seen this huge roll of carbon at the shop like the size of a huge roll of insulation does it just sit in the grow row room collecting odors....
Have you notice the smell of your buds being altered?
Is your ozone placed high or low?

Don't use ozone, it's dangerous to your health!

Very Informative Creating a Negative Pressure to me sounds like a hole some were bring air in and a hole somewhere else pushing air out duct is just a tool that does something else but not needed.
Faults in Foundation will suck air in due to negatives and will circulate the room and probally exit through the fan pushing outwards through the filter

even if in attic? wouldnt it convert to oxygen by the time its reached me if a fan pushes it away from the main entrance it could travel through?

it certainly couldnt be more dangerous then co2 right?

Ozone is not that bad. It is used all the time. Ozone is that smell you get after a lightning storm.

You don't want to be breathing in high concentrations but it dissipates very quickly anyway. I wouldn't inject it into my grow room as it's not great for plants (as it's not great for people) but if you are exhausting into your house, attic, or backyard, inject a little into the exhaust duct.

alright mate. ozone generators are not designed to run in the same room as your crop. they should be used in your ducting from your carbon filter as extra odour control, or on the outside of the room to clear up any lingering smells that might escape. the key for good odour control is negative pressure, have a larger out take than intake and buy the best carbon filter you can afford. you should also be very carefull when using ozone generators as they can cause serious problems if you breathe in the ozone. always read the instructions before using. hope this helps.

I've found scrubber placement doesn't matter much, might be slightly more effective when placed closer to the origin of the smells, but I use giant ones with big fans so all the room air gets run through them often.

Have noticed slight loss of smell only when growing, when cut and cured they smell just fine, no loss at the end.

Ozone is in my airlock, 8" CD unit with a 8" duct fan on a speed controller to keep it quiet, runs 24X7 and the only smell when you open the door is ozone! Good stuff, also kills airborne bacteria and mold spores, etc.

Just don't stick your face in it for a long time, or breathe high concentrations of it for a long time or it will burn your lungs. I have some ozone test strips I use, tells me if the level is unsafe, have never gotten close to unsafe levels in my room because there's a lot of airflow.
