Weed Plant Stages & Growing Life Cycle Explained

Weed Plant Stages & Growing Life Cycle Explained

One of the most amazing things about growing marijuana is to monitor the entire life cycle of the plant in a year or just three months. The cannabis growth cycle can be long and painful given what it takes to turn a small seed into a giant plant, but the end result is difficult to quantify. Clear changes to plants represent the stages of individual weed plants, a feature that mimics the life of plants and animals throughout the globe. Read on to learn more about the cannabis life cycle and what you know about each stage.

Growth cycle overview

The cannabis growth cycle largely depends on whether you are growing or not Indoor or outdoor weeds.. In indoor cultivation, the cultivation conditions can be manipulated, so the plants “trick” to bloom faster than normal outdoors.

Outdoor weeds work on the sun’s time clock and rely on hot, long days to maximize their potential. Greenhouse weeds are somewhere in between, as light deprivation techniques can be used to control their growth stages.

Overall, it takes 4-8 months to grow marijuana from seeds. However, you can shorten this life cycle by using an autoflower strain or by starting with a clone. Many growers call October “Croptober” because October is the most popular time to harvest. Outdoor marijuana..

Cannabis plant growth stage

Of course, all marijuana plants start out as seeds. These seeds are the product of male plants fertilizing female plants. As a rule, weed seeds are relatively impervious to what you throw at them and will survive for quite some time. However, there is a possibility of “freezing and dying”. Prolonged exposure to temperatures below 20 degrees Fahrenheit will render it unusable. Let’s find out what happens next.


If the seeds can be prevented from freezing, the next step is germination. At this stage, the seeds are exposed to moisture and light and removed from the shell.You don’t necessarily need soil to germinate, but you need some kind of soil Nutrients Value when it starts to grow. The germination stage is usually indicated by the leaves of two cotyledons that appear on the soil.

The germination stage takes 3 to 10 days, but some seeds germinate in a minimum of 24 hours and a maximum of 2 weeks. During this time, the seeds require 16 hours of light per day.


As soon as the seeds germinate, the seedling stage begins. This is when the actual leaf growth of the classic ridges begins to appear. At the seedling stage, the plant develops a stronger root system, which settles deep in the soil. It also sets the stage for the production of chlorophyll, which is required for growth after the cannabis growth cycle.

At this time, the seedlings need to be kept warm and provided with nitrogen-rich nutrients. Leave the lights on for 16 hours a day. This stage lasts from 2 to 3 weeks, but some strains have extended this stage to 6 weeks.

Vegetative propagation

Your plant is beginning to take shape as it enters the vegetative growth stage. Don’t be surprised to see them grow up to 2 inches per day, as large outbursts of growth occur and baby plants devour nutrients. At the vegetable stage, plants become more and more responsive to light. This allows indoor growers to control the lighting conditions during this time.

As they grow, Sativa takes on their terrible appearance and the indicators begin to look more round and bushy. But that’s not the only change. The vegetative stage is like the puberty of a plant. Male plants grow pollen sac, and female plants produce two white pistils. Be sure to remove these pollen sac to avoid pollination problems.

Keeping these growing babies warm, moisturized and well nourished will allow them to take off immediately. The light can stay on continuously for only 16 hours and up to 24 hours. The vegetative stage lasts about 3-8 weeks.


The flowering period is the home stretch of all marijuana plants. In low light, plants will sprout at the end of their life cycle. The flowering period lasts 6-9 weeks and is divided into three parts.

  • Preflower | Weeks 1-3: The pistil is evidence of anterior flowers, and these white hairs indicate where the buds grow.
  • Midflower | Weeks 4-5: The plant has stopped growing and is directing all its energy to the formation of flowers. As the buds get thicker, the pistils change from white to amber.
  • Late Flowers | 6th Week of Harvesting: As the trichomes ripen, the buds become sticky and the sweet scent of fresh cannabis fills the air.

For flowering plants, less than 12 hours of light per day is best. The plants are mature, so be sure to wash them off to remove any salt or nutrients that remain on the plants. When the trichomes turn light brown like brown sugar or caramel, you know it’s time to harvest. Don’t wait too long to harvest. Otherwise, the THC content will decrease. If in doubt, choose an earlier harvest than a later harvest.


It was finally time to cut down the plants as soon as they were fully matured. This is done by cutting the plants into branches and hanging them to dry. It is important to be especially careful when cutting and transporting branches to avoid damaging the fragile trichomes.

A dry room should maintain a humidity level of 40-50% and should be hung for about 10-14 days. If the humidity is too high, mold can develop, and if not enough, the shoots will dry quickly and the weeds will become brittle.


Once the cannabis is dry, prun the sprouts. This is a tedious process. This is because you need to first remove the buds from the stems and remove the leaves of all the fans. Then use sharp scissors to cut off the sugar leaves on all sides of the bud. The goal is to remove enough and not too many. Different growers seem to have different preferences for how weeds are cut, but the most important thing is to maintain the shape and shape of the buds.

Once the buds have been completely pruned, it’s time to heal them. This part can take several months and the buds need to be sealed in an airtight container. For the first few weeks, the bottle is “burped” by opening and closing and oxygenating, then sealed and replaced. Save it In a dark place. The hardening process produces better tasting weeds and a smoother smoking experience.
