I have no odor control.. just exaust.. I plan on 6 -8 plants.. will his be an issue?
Most likely, yeah. Potentially a big issue, depending on strain, size of plants (moire plant matter = more smell, obviously), and humidity levels (higher humidity usually = higher smell) and maybe other factors, too, but definitely those 3 affect smell. You could have a huge odor issue on your hands.
It can be a really big deal. You could get potentially busted if you get unlucky and it smells.
What I did before I had my carbon scrubber and ozone gen was to put literally 6-20 dollar store air fresheners in front of the exhaust (outside), which had to be hidden from view and rain, obviously. I used as many different kinds of fresheners as I could get, because since none smelled "natural", the best I could hope for was for them to smell very unlike weed, but also not like someone was using 6-20 dollar store air fresheners to hide a smell.
That was my logic, anyway.
Some actual scientific theory, while I am at it:
The thing about most smells is that a human being gets used to them. So, if you are smelling a certain smell for longer than like 15 min or so, you don't smell it anymore. Someone who walks in from outside, though, will smell it right off. This is one reason why some people use waaay too much perfume/cologne. They think the smell went away, and apply more, when in reality, they just got used to the smell.
It is noteworthy that dogs, on the other hand, do not "get used to" smells. Also, it is impossible to mask a smell so that a dog won't smell it. You have to get rid of the smell.
When a dog smells something, they can pick out all the different individual smells that make it up. Basically, if the dog could talk, they would be able to tell you that there was a masking odor, and whatever other odors are there, no matter how much masking odor is present.
So, it makes sense to get real odor elimination as soon as you possibly can.
For very small scale grows, chemical answers like ONA gel, etc, can work for this, but it becomes impractical very quickly on larger scale grows to do this and to remove enough odor.
The other 2 options are basically scrubbers, and ozone generators.
I think I might have it dialed in nicely now, if what Ozoner said was true about ozone rejuvenating the carbon in your scrubber earlier in this thread.
I have a real professional scrubber in the room, with the fan pulling air through it, and blowing it outside. This automatically creates negative pressure in the room.
Once I got that all dialed in, as far as where the passive intake holes would be and how they would be ducted if needed (for light reasons, and to make sure the air had to travel through the plants on its way through the room), I put an ozone generator in the path of the air, but just between the scrubber and hte last plant that the air has to go through, and put it on a pretty low setting. I am basically trying to get the scrubber bathed in a little ozone to a) kill the odor a bit before the scrubber even has to deal with it, and b) let any remaining ozone chew up the odor inside the scrubber itself, thereby extending the life of the carbon in the scrubber. Since I am venting outside, I am not concerned with breathing in the ozone, which would be bad.
It did take a good bit of tweaking to get the positioning and setting of the ozone generator to where I felt it was right. I can explain what I did there, if anyone wants, just pm me.
I hope this helps someone not get caught.
but hey lesson learned.
