The growth of the plant will begin to slow down here as well, eventually stopping altogether as the plant’s energy will be focused entirely on the buds.
This is the final stage of cannabis growth. All the previous work keeping the plant healthy and structurally sound pays dividends here as the plants begin to produce their buds. All males need to be removed at this point, otherwise, fertilization will occur and the females will lose a fair amount of yield and quality.
This is assuming the grower is using a germination technique that doesn’t involve direct planting, otherwise, they simply need to wait for the plant to sprout to begin the seedling phase.

The growth of a cannabis plant can be divided into 5 main chapters: germination, seedling, vegetative, flowering, and finally, budding. Within these stages of growth, many changes occur to the plant that should be noted and carefully watched for by the grower. Here, we’re going to dive into these different stages, to give you an idea of how long things generally take and what to keep an eye out for during cannabis growth.
Towards the end of these transition weeks, the first wispy, white hairs known as pistils will begin developing. These are what eventually will become the buds that you’re after.
The length of the vegetative stage of growth is dependent on the genetics of the plant, as well as the period of time they are receiving light. Plants can technically remain in the vegetative state pretty much indefinitely, but eventually, they will hit their max growth or the amount of growth comfortable for the room and need to be switched over to flowering.
The cotyledon leaves unfurl and start gaining height above the soil. You can see the first “true” (wrinkled) set of marijuana leaves nestled in between the cotyledons at first, and as time goes on these spread out to catch as much light as possible.

The insecticide is sprayed while the lights are on, and unfortunately this combination of insecticide + light burns the young plant. You can see the plant struggles to recover for nearly the rest of the video.

Marijuana sales soared in 2020, from $10 billion the year before to nearly $18 billion. Experts say the pandemic played a major role. "I think people turned to cannabis to help relieve stress," says author of Weed the People Bruce Barcott.
A new study from researchers in Canada has found a higher likelihood of autism in babies born to mothers who used marijuana. Experts weigh in on what we know thus far.

Power players in the cannabis industry are actively working toward dismantling oppressive systems meant to incarcerate people of color prohibit them from finding success in what is now a multi-billion dollar industry.
“I think if you want people to stay indoors and not go out and not interact with a lot of people? Pot's a pretty good thing to have,” a Seattle-based dispensary owner said.
The Indiana State Police issued the warning on Facebook earlier this week, alongside photos of “medicated” Skittles and Starburst Gummies, which contain THC, the psychoactive compound of cannabis.
