HOW LONG DOES IT TAKE TO GROW A MARIJUANA PLANT?
The idea of the following article is to provide you with valuable information about the growth of marijuana, its phases and some tips. First, we recommend you not to harvest your plants as soon as possible. Each variety and each strain follow a life cycle that we must respect if we want to achieve optimum development and a quality product.
The time of germination, growth and flowering of marijuana is relative; each variety follows a different tempo, even each strain, which is why it is impossible to determine or pre-establish a generic time for cannabis.
How long does it take to grow marijuana?
Anyway, we will try to give you some advice to guide you as best as possible and that you can control the growth of your crop. If we want to specify about the life cycles of the cannabis plant, we must highlight three main phases: germination, growth and flowering.
- 1 The germination process.
- 2 The Growth or Vegetative Stage:
- 2.1 Determining factors:
- 3 The flowering phase:
- 3.1 End of Flowering and Harvest:
- 4 Conclusions:
The germination process.
First, there is the germination process. This is usually the process that people give least importance to, but, it is of vital importance because if we do not do it correctly we can spoil the seeds. The techniques for germination are very diverse, from the typical technique that uses a napkin or wet paper, to the use of stimulators or planting the seed directly in soil, on a jiffy disc or in a glass with water.
Marijuana seed germination
The best thing to do is to use the napkin or wet paper and, as for the time, to re-emphasize that it is relative. It will not only depend on the conditions of water, humidity or oxygenation, we will also have to consider the quality of the seed, its fertility, the variety or strain in question. However, the seeds usually take between 24 and 72 hours to germinate. Sometimes we find seeds that can take 5,10 or 15 days to arrive.
The Growth or Vegetative Stage:
Secondly, we find the growth or vegetative phase. This phase is central to the development of the plant and therefore one of the main concerns for cannabis growers. It is in this phase, when the seed has been germinated and planted, in which the plant acquires its morphology and its optimal size to later be able to produce the flowers (our harvest).
During this phase the plant needs a lot of direct sun-light as it is developing.
Now, we are in the greatest photoperiod of the plant, between eighteen hours of light by six hours of darkness. The hours of darkness are also of vital importance as they will produce the correct exchange of gases. This exchange is essential for the optimal metabolic development of the plant cells of our strains. The length of time that plants should be growing will be determined by various factors such as environmental (temperature, light, humidity), plant (variety and strain) and external factors (fertilizers, soil quality or the grower’s experience).
Another factor will be whether the plant is regular or autoflowering. In the second case, all phases are shortened, as they are genetically engineered plants designed to develop as quickly as possible. On the other hand, it will also depend on whether we plant it outdoors or indoors. It should be noted that in indoor cultivation also shorten the phases, and depending on our luminous power, the times will be lengthened or shortened even more. Therefore, to pre-establish the time of growth is very complicated; to general features we could say that in an interior the autoflowering seeds we would let them grow between 3 or 4 weeks, depending on the culture technique, and 6 or 8 weeks for the feminized or regular seeds.
The flowering phase:
On the other hand, we have the third phase, flowering. This phase is the last stage of plant development and one of the most important. The beginning of this period will be determined by the hours of light, outdoor, or by the development of the plant during the growth phase, indoor. Since the interior can control the moment in which we want it to start blooming, we must wait for the plant to have the right physiognomic characteristics to produce good buds.
In autoflowering varieties, the beginning of the flowering phase will mark them themselves, while in feminized or regular seeds, we should be the ones who, through the change of photoperiod, point out when they should start to flower (setting 12 hours of light and 12 hours of darkness). Another issue is outdoor, where the calendar will determine the tempo. As for determining the end of the flowering process, point out that it is something completely subjective. There are people who prefer to wait more or less, although there are certain factors that can give us a general idea.
End of Flowering and Harvest
End of Flowering and Harvest:
Firstly, the development of buds, which should fatten to cover most pistils. Secondly, the correct maturation and oxidation of the buds, which will be determined by the color and shape of the pistils and trichomes, which may be orange or brown in color. Finally, the hardness of the bud can also be an indicator of the time of cutting, although there are varieties that produce softer buds and therefore this indicator does not always work. However, we can point out that autoflowering plants will usually complete their flowering in eight weeks, whereas feminized plants can take up to ten, twelve or even thirteen weeks.
By way of conclusion, as we have seen throughout the article, the duration of the periods is very relative and depends on a great variety of factors. However, some generic and approximate calculations can always be offered to guide the grower.
We establish, therefore, that for the correct development of an autoflowering marijuana plant, we must wait approximately three months; while for a feminized plant, the period is extended to four or five months. These have been some advices to help you with your crop, since Gea Seeds recommend you perseverance and a lot of patience to get the best result.

I have been doing this from 3 months but yet no flowers on my plants….. I’m growing them outdoors…. And seeds are regular…. Can u give some advice when will it start flowering…. Today 3 months are over since I have put seeds in wer napkin……

The flowering does not depend on the number of months since the germination.
The flowering depends on the hours of daylight.
In August and September (Northern Hemisphere), when it starts to decrease the hours of the sun, the plant will start to bloom.

My bush has just started flowering, will it take me a few weeks to cut out a garden?
GeaSeeds 2 October, 2020, 1:43 pm
Yes, between 5-9 weeks more.
Depends on strain type

These are very common questions for new growers, so let me give you the straight answers…
How long will my marijuana plant take to grow? How long from seed to harvest?
It will be 8 weeks – 6+ Months before your plants are ready to harvest.
But that’s a huge range, right?
The truth is, the time to harvest depends on your growing method, whether you grow inside or outside, your strain, and your desired yields…
Growing Method – soil tends to be the slowest growing medium, and hydro tends to create the fastest growth
Inside or Outside – In general, outdoor plants need longer to harvest than indoor plants. Outdoors, you plant in the spring, and harvest in late fall, taking 5-6 months or more. Indoors you have more control over the plant and can choose how long you want your plants to grow before harvest, and can get to harvest in just a few months. Indoors you can also start growing at any time (you don’t have to wait until Spring to start growing).
Strain – Some strains tend to have shorter lives, and others need longer before they’re ready to harvest. For example, you can choose to grow an auto-flowering strain to get to harvest in as short as 8 weeks. But many strains which originated near the equator can take months and months before their buds are ready to harvest, even when growing indoors. So strain is important when it comes to time-to-harvest.
Desired Yields – If you want bigger yields, you need a bigger plant, and that takes more time to grow than a small one.
Discover Exactly How Long It Takes Before You Get to Harvest
How tall will my marijuana plants get?
Plants can be grown shorter than your knees, or taller than your house.
Basically you (the grower) are in complete control of how tall your cannabis plants grow.
This is especially true for indoor growers, where you are in charge of nearly everything. When growing outdoors, you still have a bit of control over plant height, but you are also at the mercy of the sun and the elements.
Some strains tend to grow tall and thin, while others tend to grow short and squat, but you can force your plant to grow differently when growing cannabis indoors. In fact, you have many options to control the exact shape and size of your plant.
To learn about all the tools and techniques you have available to control the height and shape of your plant, take a look at our Plant Training & Height Control guide!
Short plant in a small space – this plant is only about two feet tall thanks to training with a screen, yet still producing lots of bud! You don’t need a huge space to get a good harvest when you use plant training.
These cannabis plants were also trained to stay short, this time using LST – they were under two feet tall at harvest and produced more than 6 ounces of bud under a small grow light!
These plants were trained using manifolding. They were about 5 feet tall at harvest, and produced more than a pound of bud!
You can achieve almost any size or shape when growing indoors as long as you use plant training. But if a cannabis plant is left to grow outside with tons of sun and without any plant training, the sky is the limit for how big they can get!
Although it isn’t the be-all end-all when it comes to size, strain is still definitely something to keep in mind when it comes to height. Although you can control the exact height and shape of your plant no matter what the strain with plant training, different strains grow differently and you want a strain that makes it easier to get the results you want. When growing with bagseed (seeds that you find in your buds) you often don’t know what to expect until the plant actually starts growing.
For example, some strains (known as “indica” strains tend to stay short, while “sativa” strains tend to grow tall). Just to give you an idea of the difference, these plants were grown in the exact same setup.
To fight these natural tendencies and force these plants to be the same height, the grower would have needed to use different techniques and training strategies. If the grower had wanted to make the right plant shorter, the plant would have needed more Low Stress Training and Supercropping.
For the left plant to grow taller, the grower would have needed to give the plant more time, since indicas tend to stay short. So even though you can force plants to grow into any size and shape, it’s often easier to start with a strain that naturally grows the way you want. That way your plant is working with you instead of against you. Learn how to find the right strain for your needs.
