I've read some posts that it's not good to run a carbon filter in the same room that you are drying your cannabis in as it affects the trichomes. Any thoughts on how to handle the odor if this is true?
Effects its trichomes how? I was recently sent this video on how carbon filters can effect terpene profiles: https://www.youtube.com/watch?v=ft3bybCMykY
Is that what you are referring to? As long as you're exhausting the air instead of scrubbing the air then you should be fine.
I actually don't use a carbon filter as a scrubber. For my setup, air gets pulled into a carbon filter via inline fan and then exhausted out of the grow space.
According to the DGC video, if the carbon filter is inside the grow room, you are scrubbing the air inside the grow room. They said the carbon filter should not be in the grow room as it will negatively affect the flowers/terpenes. They recommend scrubbing the air outside of the grow room where you want to eliminate the odors. Watch the video again and let me know if I am misunderstanding something please.
The idea is that the air volume holds a certain amount of terpenes in the air creating an equilibrium with the plant. Kind of like with humidity in the room, but i don’t believe the same action. So if the filter remains in the room, the terpenes in the air will react with the filter even when it is not moving air through it. This equilibrium change would cause or allow the plant to volatilize or release terpenes to maintain equilibrium, which is why they recommend a sealed room. Any time you exhaust the room it will change equilibrium when a carbon filter is in the grow room. Make sense?
Oh I totally understand what they are saying. I feel like the impact is so minuscule though that's it's not even worth worrying about. Although, there isn't a way to measure it so no one really knows the impact.
I personally don't want to run a sealed room due to heat buildup and cost. I would much rather exhaust the hot air from the grow room instead of adding in an air conditioner which can use a significant amount of electricity. Also, sealed rooms require CO2 supplementation. I'm just a home grower that grows a small amount of plants for personal use so a sealed room would be an overkill for me IMO. Everyone's situation is different though and everyone has their own "grow goals".
Do you currently run a sealed room?
EDIT: I just re-read your original post and realized you're referring to the drying process. I do not run a carbon filter and exhaust setup in my drying room/tent. I stabilize the RH to 55-60% and then open the grow tent or exchange the grow room air once a day.

Yup that’s the video I’m referring to. What are your thoughts on it? Do you change your carbon filter to exhaust during the drying process?
So your carbon filter is installed outside of the grow tent? Because in many of your videos it is shown inside of the grow tent..
No, it's inside the grow tent and its connected to ducting and inline fan which exhausts the air out of the grow space.
Scrubbing recycles the air into the same grow space - so not exhausting. I don't have it set up like that.

Yes, you're misunderstanding. See this picture to understand. The setup on the left is scrubbing the air and the setup on the right is exhausting the air. https://www.kushandkind.com/wp-content/uploads/2015/05/4-150CFM-Hydroponic-Air-Carbon-Filter-Odor-Control-Scrubber-for-Inline-Exhaust-0-4.jpg
Here's a video explaining scrubbing: https://www.youtube.com/watch?v=hrKy2errkTw

Yeah I think the drying process is when the carbon filter apparently causes issues, but I need a way to handle the smell during drying also..
