how do i stop this!

I don't want my room or anypart of my house to smell like weed when I start flowering how can I hide the smell this is a secret stealth closet grow I can't have smell!

adding a carbon filter to your exhaust

That's what I read. Can I use a carbon filter for a larger fishtank since I'm n a small closet grow?

I have never built one myself, but there are a few different diy carbon filter tutorials on this site... https://www.rollitup.org/indoor-growing/7074-easy-build-diy-carbon-filter.html is one of them.

Thanks man

1. Air freshener. Don't rely on this alone, but it will help mask the smell.

2. Proper ventilation. You might think that fans blowing that weed smell out of the closet isn't good. But if you let the weed smell build up, it will just pour out of the closet eventually, and it will be very strong.

3. I've heard of using carbon filters. I know nothing about them. I don't even know if I'm thinking of the right thing. But I would google carbon filters and see what's up with them.

I just bought a carbon filter it works great but I only bought it cause I vent outside. Try this out https://www.rollitup.org/indoor-growing/241418-rosemans-odor-bucket.html
