Odor! woo hoo.

Stink of your plants depends TOTALLY on strain and conditions. Some strains will stink up a whole area from the time they are still quite small, while others (sold as 'low-odor' if you use the searhc function in seed vendor site queries) can go right through flower with very little detectable odor, or even an odor fairly UNLIKE cannabis.

Also, your temperature and nute regime play a part in this.

A good rule to follow is you DEFINITELY need odor control in flower if you are trying to grow even somewhat stealth, and the scale of the odor control and the scale of your LIGHTS should match. If it's a super stinky strain, go overkill on smell control. You get used to it being around it all the time; the postman does not.

I had a frightening moment a while back pulling up to my house on a day when the air was still and smelling the stank BEFORE I GOT OUT OF MY CAR. You can bet your buns I ran out and bought a better blower and filter THAT EVENING!!! lol
