they did stink but i had numerous air freshners in the house. the room was pretty much sealed with 2 sliding doors, a homemade carbon scrubber and a bathroom door with a towel underneath, on top of a bedroom door always with a towel slid underneath with a 500 dollar air purifier my dad loaned to me, windows sealed off with cardboard and foil tape. front door and back door was always closed and double locked. i would love to have them use smell as evidence for a search warrant. if this gets thrown out due to smell i swear to god ill come back 5 times as strong next time.
