Hello,

I’m hoping to get advice and information on smell management in a grow room. The problem is that smell gets through carbon filters and bad smells get outside of the grow room. The grow room has a slight problem with overpressure but we’re thinking it’s not the whole problem. Unfortunately bad smells get out on the streets close to harvest time, and it’s quite uncomfortable.

I swear I’ve seen a ventilation attachment that has a perforated pipe inside a ventilation pipe that you can stuff with Ona Gel. Has anyone else seen or heard about this? Please give links.

Any advice is very welcome, thanks.
