When does it start to smell when growing weed?

The cannabis buds we know and love have a noticeable smell. They stink. I love the smell, some people hate it, and every strain is different.

But when growing weed, do the plants start smelling? And how much?

What do these cannabis plants smell like?

The answer is that each individual strain and plant is different. But here’s what to keep in mind:

At what age do cannabis plants start to smell?

Short Answer: The smell starts at 3-6 weeks old (depending on strain) even in the vegetative stage. But the smell gets much worse after plants start flowering/making buds.

The leaves of a cannabis plant smell a little, but the buds smell a lot. When plants are young they don’t make a lot of smell, but once the plants get big and start growing buds, the smell can be intense.

  • Cannabis plants are too small to smell for at least the first few weeks after germination.
  • Most plants don’t have a whole lot of smell until they get big or start flowering (making buds)
  • However, I have grown strains where plants start smelling at only 3-4 weeks old in the vegetative stage
  • Usually, by the time any plant is 6 weeks old, it’s big enough to have a noticeable smell


  • Leaves make a smell, but buds create an intense aroma
  • Bigger plants smell more
  • More plants smell more
  • Some strains smell more than others
