I'm assuming they don't really smell at all until they start flowering, so like autoflowering strains about 2 weeks in and normal plants about 6 weeks or whenever flowering starts? What are your experiences?
another thing... the only time I did smell it was when I had 6 vegging in fresh FFOF soul. I could smell a earthy smell but thats it
I have three, 5 week old plants in a stealth closet, inside of a walk in closet inside of a bed room on the 2nd floor of my house... and yesterday I walked into my house from the garage... and the smell hit me like a ton of bricks. The smell started filling the bedroom after about 3 weeks.
I usually start smelling mine at the 4.5-5 week mark specially when the AC isnt one during the day and the lights are off
