First time grow flowering question?

How bad does the smell get? Can it seep through thick drywall? i have a carbon filter running as well

some can be smelled down the road. i had a strawberry cough last year that you could smell thru the filter, it was strawberry and I was growing some outside in my other legal garden.

any other suggestions to reduce smell?

Every strain I've ever grown fucking reeks to high heaven. Unless the room is sealed off then your whole house is gonna smell like a fresh dope garden.

My suggestion is patchouli oil. I haven't used it and can't even stand the smell of it, but that shit will cover up the smell of anything.

If you have a good carbon filter running expelling the air with negative pressure in the room, no worries. If you don't have negative pressure, then you can have odor leak out.
