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.
@D K 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.
So I have an issue. I purchased the carbon filter from your 4x4 complete grown tent setup from YouTube. And when I connect it, no air gets pulled out of my tent and my tent blows up like a balloon. So I unhooked the filter and boom. The airflow was fine and my tent deflated. Should I order a ac infinity air carbon filter?
It inflated? So that means when you turn the inline fan on, air is coming into the tent. You may just need to flip the inline fan around so air is being pulled from the tent instead.
This filter is brand new though. I just hooked up my intake fan and sealed up the tent. for the time before this, I left the tent intake spot unzipped for airflow. I dont Think this carbon filter was ever getting any air flow through it. Has nothing to do with over time use.
Ah, that may be it. So since tap water has minerals in it, if you put it into your humidifier then those minerals are attached to water vapor and quickly clog up your carbon filter. It's actually just the white pre-filter though. If you remove that pre-filter and simply hand wash with water and squeeze out then you should be good. It's often advised to use RO water or distilled water in humidifiers in order to prevent that issue from occurring.
Hey corey, if you hook up the filter and your tent balloons up then you have "positive" airflow and if your tent collapses you have "negative" airflow. It sounds like your filter might be too small for your fan, and wont let the fan breathe properly hense the reason it blows up like that.
Also I forgot to mention that I have dried the same smoke with and without a filter and imo I couldn't tell the difference. I first started using one for odor control, but then no longer had to worry about smell and took it out. Seems the same to me or at least what Mr.G said it would seem so miniscule that it would take some kinda computer analysis for comparison.
I was using a carbon filter because it is being exhausted in my attic and I just don’t want my neighbors to smell it. But I ordered a 6 inch carbon filter which is plenty big. I have a strong outake fan and a intake fan that is too strong but I turn the power down some on the controller.

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..

Is it a Vivosun filter?
It’s from cool grow. Got it from amazon. Straight link from the YouTube vid

Nice setup you've got there. This may sound like an irrelevant question but are you using tap water in your humidifier?
Funny you ask. I am. Is that an issue? I live in AZ and out water is considered hard at 7.8 PH.
This filter is brand new though. I just hooked up my intake fan and sealed up the tent. for the time before this, I left the tent intake spot unzipped for airflow. I dont Think this carbon filter was ever getting any air flow through it. Has nothing to do with over time use.
