options to use two carbon filters

[leprechaunleaf]

I'm growing and have one small problem I need to correct. A small amount of odor gets past my single carbon filter late flower, I'd say around 10% of the odor gets past my filter. From what I've read, this is normal, a small amount of odor may still escape. So, the single carbon filter is reducing odor (greatly)--but not completely....

Options to get that last bit of odor taken care of: (fingers crossed)....

1. Install two carbon filters onto a single fan. One for intake, one for exhaust. This seems to be the simplest solution, but I am concerned that I will be over working my AC Infinity fan...

2. Install a second fan and carbon filter outside of my tent at the exhaust of my internal fan and filter. If done correctly, I think the outside filter may capture the slight odor that is escaping.

3. Install a second fan and carbon filter inside my grow tent to scrub the air internally.... (while using another fan and filter to exhaust out... This take room out of my grow space though and I'm not sure how effective it will be.

4. Install home ventilation to vent outdooors.. This may be expensive, the idea is to install something like a bathroom fan to vent outdoors.


I'm leaning towards option two. Has anyone else tried this?

Option 2 if you place it directly at the exhaust, it may not be fast enough to get all the air. If it runs the same speed as the inside fan it would work i guess.

Option 1 will work if your fan has enough power. If you're operating the fan on the highest settings already, it'll not be good.

Option 4 sounds like the best, especially for the very hot days. Will the little smell be a problem for people outside?

Only used a second fan with carbon filter placed in the room and it worked. Ona classic is also great outside of the grow room.
