GROW ROOM ODOUR CONTROL
The best way to remove odours is with a carbon filter. Nothing else works as well. Never, ever, ever extract any air before it has been through a carbon filter.
If you’re still getting lingering smells, you can remove these with:
- Ozone generators
- ONA blocks, gels & sprays
If that’s still not doing it, try reducing the heat and humidity around plants in flowering. That way there will be fewer VOCs to remove.
