when growing weed does it smell

The researchers speculate the airtight container locked in VSCs better than samples contained in standard zipper-lock plastic bags. However, previous studies didn’t find a significant effect of zipper-lock bags on the concentration of cannabis odors, so the jury’s still out on this one.

According to the scientists: “The rapid increase of VSCs was concomitant with an intense rise in the pungency of the skunk-like aroma of the flowers.”

After the tenth week of growing, when cannabis flowers emerge, the scientists cut, cured, and dried the cannabis for 11 days. The concentration of VSCs — and the potency of the skunk smell — dropped significantly 10 days after the curing process, showing how cannabis smell weakens with time.

The researchers in the 2021 study analyzed and identified a new class of compounds, known as volatile sulfur compounds (VSCs), in cannabis sativa. Some of the compounds the scientists discovered have never been previously identified in nature.

How does age affect cannabis smell?

The researchers conducted smell tests, which “confirm that VSC3 is the primary source of the characteristic scent of cannabis, while the remaining compounds VSC4– VSC7 may further intensify or modulate this aroma.”

The researchers write that cannabis “samples with older product ages tend to have lower VSC concentrations.”

A study published earlier this year in the American Chemical Society reveals a family of chemical compounds are likely responsible for the distinctive pong of marijuana. The findings offer a new way to consider not just the chemical origins of cannabis’ particular scent, but also a way to examine its untapped health benefits.

What does cannabis smell mean?

It’s not clear whether the VSCs in cannabis confer similar health benefits, but the researchers argue the similarities between VSCs in garlic and cannabis “thus warrant further investigation to determine if the former possess similar health benefits to those of the latter.”

The researchers also confirmed what many regular cannabis users already likely know: Time can affect the potency of cannabis smell. In other words, they seem similar to typically pungent spices in that the odor has a shelf-life.

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.

At what age do cannabis plants start to smell?

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

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?

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.

Smell Follow your nose. A cannabis crop takes about three months to produce. During the final four weeks, the plants stink. Earlier this year, Crimestoppers helpfully issued cannabis-farm scratch-and-sniff cards to 210,000 homes in the UK to help you identify the exact bouquet.

Ventilation Growers need to ventilate the plants with large extractor fans, which generally emit a low hum. If every morning, at exactly the same time, it sounds as if someone next door is starting up their hovercraft, then it’s probably a cannabis farm warming up for the day.

I n the course of making a film about Britain’s cannabis industry, I have learned a lot about how to spot a cannabis farm. I have been schooled by policemen who raid them, gangsters who rob them and growers who set them up and produce more than 80% of the cannabis smoked in the UK today.

But you may not be the only person trying to spot a cannabis farm on your street. The sinister side to these booming businesses is that they have become lucrative targets for harder and more violent criminals looking to rob them. These people are constantly on the look out for farms within our communities, which in turn exposes the rest of us to potential violence. What’s the solution? The dealers and criminals I spoke with all said that legalisation would put them out of business.
