I'm gonna throw in my 2 cents as i just went thru this scenario and nearly paid the ultimate price.I grew for 5 years in a rented place,had the best carbon filters and exhaust i could get,and no one ever knew i was doing my thing-UNTIL that one off the wall time the ol landlord paid me a visit that one time in 5 years. I had 15 plants out for water and the smell was obvious as they weren't protected by the carbon filter at that moment. Although he never saw the plants he smelled the hell out of them and it was obvious what was up and he left quick. In 2 hours i had gutted 2 growclosets and both ventilation systems,chopped and buried 15 plants,some of which were a large seedcrop. good thing paranoia kicked in as 2 days later i had a surprise dwelling inspection and would have been cooked if i hadn't pulled the plug. I knew growing there was done for good and in this past month i've bought my own place out in the middle of nowhere where things are alot safer. In my super paranoid state i even had my old account deleted herejust to cut ties with anything remotely grow related. My advice to you,and u may not like it,pull the plug and quit until u get your own place. If theres already been talk of a weird smell at ur place then someones already suspectin somethings up and by mentioning it their either tryin to flush you out or give u a chance to get rid of it. One plant ain't worth the trouble that comes with it being found-trust me on this,hell,i got rid of 15 and it was worth it to keep my freedom. You can always start over. the smells only gonna get more potent the closer it gets to finish. Not tryin to discourage you bro,just tellin it like it is so u don't have to go thru what i just been thru.
