its funny , how people become accustomed to the smell in there own house , my mate was growing 2 huge 'cheese' in a grow tent under a 600 , with no carbon , when we was chatting he said he was worried it had no smell ,and we all know cheese stinks , so anyway he invited me round for a smoke and to see how his plants were doing , im not kidding we pulled up on his driveway and as soon as i opend the car door i could smell cheese , i said , fuck me they stink mate , he said yeah right thinking i was joking , i had to tell him i can smell them outside your fukin house dude , and arrrr man when he opend his front door it stunk like bob marleys back garden , i said i cant believe you cant smell them they fuckin reek , anyway soon after my visit he got some filters and hes not grown cheese since .
