If I put a carbon filter and fan in my drying area would that decrease my terpenes? I run a portable AC and vent to a different area of basement but basically the whole house stinks. Really doesn’t bother me but trying to be a little more discrete.
Thinking of putting a carbon filter on floor inline fan on top of that and a few feet of hard duct on top. Should be beneficial for circulation.
My temp is around 65-67f and around 60% humidity
the carbon filter, only filters the air, so the smell particles, that are in the air, will be filtered, so no, you wont loose your bud terps
what could you loose some terps, is high temperature and light in your buds
Can’t picture how that would hurt terps🤷🏿 but what do i know
My brain? I wouldn’t think it would hurt. Carbon filters impress me what they do. Just thinking nature doesn’t like a vacuum? Like the smell wants to go somewhere? Bud in a jar vs sitting on table?
The activated charcoal only captures molecules in the air that pass through in very close proximity, so really only the air passing through the filter would be affected.

Decrease terps by filtering the air? No way man and really only high temps can burn off terpenes but that’s in the high 80s 90s + range.
Howdy @broncogrow, as others have mentioned using a carbon filter to scrub the volatile gasses released by terpenes and/or other aromatic secondary metabolites into the surrounding air will sort you proper in terms of your wanting to be more discreet.
As for your concerns about the newly introduced pressure variability from adding a fan to the space, it’s said that:
Pressure directly affects terpene volatility, as increasing pressure reduces the tendency of terpenes to evaporate, meaning higher pressure results in lower terpene volatility; this is because a substance’s vapor pressure (its tendency to evaporate) is inversely related to the pressure exerted on it, so at higher pressures, less of a substance like a terpene will vaporize readily.
I believe negative pressure when compared to surrounding atmospheric conditions is considered to be low. I don’t think it’s too much of a concern as many grow and produce greatly fragrant flowers within setups utilizing negative pressure, carbon filters and such but technically it seems that negative pressure influences vapor pressure which in turn influences volatility of aromatic secondary metabolites. A fan recirculating air in a room shouldn’t contribute towards negative pressure though, but a fan that’s setup to exhaust outside of the space the fan is in can create negative pressure. Hope this helps. Many blessings and much love

Thank you for your help. I’m new here and so far I’m impressed with the community. but say you got same environment conditions. One bud in a small jar to accommodate and one in the open. My stoned head says the latter wears off?
I’m definitely gonna try it. Discretion valor?lol
To be clear not in a tent situation. Basically no ceiling just rafters
What if the air is lacking terpenes? I know I chase them lol
Hey with the whole endo canabaloide system maybe similar.
I have been smoking
Homeostasis lol
Howdy @broncogrow, welcome to Overgrow. I think it depends on a few things, and also I could be totally off base with what I’m saying as I’m not a professional scientist or chemist. This is how I think of it though. If the jar is vacuum sealed then it would be in an atmospheric environment similar to negative pressure, meaning low pressure so less forces acting on the secondary metabolites to keep them from evaporating. Whereas high pressure atmospheres will reduce said volatilization. I think during the process of vacuuming more aromatics would evaporate than if they weren’t placed under vacuum.
Without being vacuum sealed the atmospheric pressure within the jar should be similar to the atmospheric air of the surrounding air outside the jar when closing the lid, so I wouldn’t imagine it much different in a jar compared to being left out in the open in that regard.
Having said that, I believe the airspace within a jar that’s not occupied by flowers or dried buds will influence a difference in the aforementioned scenarios. As a flower or dried buds outside of a jar in the open have nearly unlimited surrounding air for their aromatics to evaporate into, inside a jar there is limited space for said aromatics to evaporate into. They can still evaporate and diffuse into the airspace in the jar, as can be observed when opening lids and/or burping a jar filled with buds one can notice the aromatics wafting out. It’s why it’s recommended, in my opinion, to fill jars as full as possible to reduce unnecessary air space within a jar at where aromatics could otherwise evaporate and diffuse into. Full jars make for less airspace that aromatics can diffuse into whereas more airspace in the jars gives way to more airspace for aromatics to diffuse into. Flowers outside of a jar just in the open are basically in a jar the size of the planet with basically infinite airspace. I don’t know for sure but I assume a jar that’s full with flowers and less airspace has higher pressure that’s being exerted on the aromatic filled structures than a jar with less flowers and more airspace, but I could be mistaken about that. I could be mistaken about that because I’ve always been taught to fill jars full without unnecessarily smushing the buds without any additional information than do it that way because less airspace means less room for things to evaporate and diffuse into. So I’m just tying bits and pieces of what I was taught with what I think I know about pressures, and terpenes and such.
I think it comes down to higher pressure atmospheres inhibit evaporation because higher pressures require higher boiling points as stated in the following:
Pressure directly influences boiling points by determining the temperature at which a liquid’s vapor pressure equals the surrounding pressure; higher pressure requires a higher temperature for a liquid to boil, meaning that as pressure increases, so does the boiling point of a substance.
Many blessings and much love
I think I can visualize this. I have some HVAC experience with a vacuum pump. I put a jar back the other day with a hand pump. Harbor freight brake bleeder. In my head I think it would be wrong but hearing it’s right. Don’t intend to open it till my other jar is at the bottom. I will have some A B testing to report in a month say.
With this question no pressure difference just the carbon stealing my terps. Lack of flavor in the air? The air must be flavored. I’m giving her all she’s got Scotty
Was probably high but some science teacher explained how a fart traveled. Just thinking how much one trichome has to give. Don’t want to waste not one.
