Kinda of normal yes. I'd say it's best to use multiple filters if you want zero smell. I run 2x in the room and one outside it 24/7. Then I have a 4th I turn on if people are coming over.
It's your friends who are most likely to rip you off[/QUO
when i was growing in a tent i could go past 55% humidity and my filter worked fine
i got a cheap one this time and i guess there is a big difference on the quality
i dont have a normal grow room space. i use to grow in a big tent and my guess is being a bigger space humidity was keeping it self in check better then the smaller space i work with nowAgree with using multiple in-line. Including one for the hood if it’s air-cooled. All air exiting the grow area.
