How long does the cannabis plant’s vegetative stage last? – A healthy Cannabis plant grows as tall and as large as it can under the given conditions during the vegetative stage. Consequently, the size of the plant will be proportional to the size of the container and surrounding environment, if the plant has the necessary growing conditions.
- The vegetative stage of cannabis plants can span between three to sixteen weeks, or even longer in outdoor cultivation.
- Most gardeners vegetate their indoor plants for 4-8 weeks, depending on the desired plant size.
- Cannabis plants often begin blooming in the fourth week of the vegetative phase.
- Consequently, those plants will likely be lower in size.
More vegetative time and larger containers will result in larger plants that are more likely to generate more harvests. A cannabis plant in soil-filled container A Cannabis plant may be left in the vegetative state as a mother plant or stock plant in order to produce clones from its cuttings. 
Does extending the veg period boost yield?
Dear Dan, I have a query that I have been unable to solve based on my 5–6 plant personal grow. I normally let my plants to vegetate for at least 5 to 6 weeks, but I sometimes allow them to vegetate for up to 8 weeks. My question: Is there an ideal period of vegetative time for maximizing yields? For instance, if four weeks of vegetables yield 45g per plant, would eight weeks of vegetables typically yield more? Then how about ten weeks? I have experimented with Veg time but have not reached any definitive findings.
- Hi4daze – Dear Hi4daze, There is no optimal length of time to maintain a plant in the vegetative state.
- You determine how long it will take your plant to develop leaves and branches under 18 to 20 hours of light, and then you trigger blooming with 12 hours of light and 12 hours of darkness.
- The longer you leave your plants in the vegetative stage, the larger they will become, resulting in more harvests from longer vegetated plants.
The disadvantage of a longer vegetative stage is that it lengthens your growth timetable and provides more opportunity for things to go wrong along the road. Consider that vegging a plant for three months is a waste of effort with declining results the longer you do it.
I typically advise a week of vegetative growth for every gallon of growing material (ie: a plant grown in a 5-gallon bucket should get about a 5 week veg). Most individuals veg their plants for between two weeks and two months, however there are Sea of Green growers who barely veg and giant plant specialists who go longer.
It is essential that the plants remain healthy throughout this crucial growth period. Thus, they will be prepared to produce many blooms throughout the blooming stage.
Why Is My Cannabis Plant Getting Taller and Skinnier? – Finding out why your marijuana plants are growing too tall is one of the first things to accomplish. If you don’t, you could use the incorrect solution, which might harm your plant’s growth. Your weed plants may be growing excessively tall for the following reasons:
| Incorrect light distance |
| If your lights are too far away from your plants, they will stretch in an attempt to get closer. This is a natural behaviour born of trying to grow above competing plant life. |
| Weak light |
| If your lights are just not strong enough, your plants will stretch up to them no matter how high or low they’re placed—they will hunt for light until they’re satisfied. |
| Red-dominant light spectrum |
| In nature, cannabis plants grow during the spring and summer. At these times, when the sunlight is at its strongest, plants are subject to blue and white light spectrums. During autumn, the sunlight weakens and enters a red spectrum. To give your plants ample photo-fuel, make sure you’re using the right light spectrum for the respective stage of development. |
| You’ve kept them vegging too long |
| Photoperiod cannabis plants kept in the vegetative stage will continue to grow. So if you veg them for too long and don’t control it, they will grow very large and unwieldy. |
| Genetics |
| Some strains of cannabis like to grow tall and spindly—for instance, landrace sativas. While these can be controlled, if you’re really limited for height, many indica varieties are more suitable. |
How long does it take a plant to re-veg?
The benefits of re-vegging your cannabis plants are: To protect valuable phenotypes and genes. Occasionally, when harvest approaches, you will inspect your plants and realize that one of them is a killer phenotype that is simply too excellent to lose.
Re-vegging your particular plant may be your best option if you want to prevent the regret of losing a keeper. Avoid the necessity of maintaining a mother plant/mother room. Some cultivators maintain a few exceptional mother plants, which necessitates a separate grow space. If you re-veg your finest plants, you obtain a steady supply of buds without having to maintain a separate, dedicated mother room.
shortened vegetative periods Fans of re-vegging believe it can save time during the second harvest, despite the fact that not everyone habitually employs it. The reasoning is because the plant already has an established root system and stem/branches, allowing for fast regrowth.
Since the re-veg procedure might take more than a month, not all farmers are convinced that shortened veg periods are a significant benefit. Possibility for greater harvests. With an established root (and branch) structure, the second harvest might be heavier than the first. However, this may necessitate an extended re-veg interval.
Remember that early regeneration will exhibit only a single leaf. Slowly, 3-fingered leaves will evolve into 5-fingered leaves. The recovery of normal leaf structure requires time. Before considering a second bloom, re-vegging enthusiasts often wait until the leaves have 7-9 fingers.
Are large fan traces a positive sign? – The state of your fan leaves reflects the overall health of your hemp plant. Large, green, and healthy fan leaves indicate a vigorous and healthy plant. As long as these leaves are healthy, it is generally recommended to keep them in place when pruning, particularly during the vegetative development phase.
What happens if you put off harvesting too long?
By delaying the harvest, the trichomes have adequate time to grow. However, the longer you wait, the more sedative and intoxicating your flower will get. This is particularly true for indica strains, but sativa strains can also induce drowsiness.
After two weeks, how big should my weed plants be? Your plant should typically be between 2 and 3 inches tall and have two to three sets of leaves, including the cotyledons (seed leaves which are rounded). The quality of your seeds, the soil you’re germination them in, and the quality of the light they’re receiving will all have a significant impact on the results.
- Your sprout may start to grow tall in an effort to reach closer to a light source if it isn’t getting enough light.
- You could be using the incorrect kind of light if you are using a light and the seedling is still extending.
- Use a light source that contains some blue; “cool white” bulbs are suitable for seedlings because of this.

Buds sprout throughout the day or night.
By Nebula Haze To initiate blooming and produce buds, cannabis plants require short days (or, more precisely, long nights). The majority of indoor growers give their plants 12 hours of darkness and 12 hours of light every day to commence budding, and they maintain this light cycle until harvest.
- A 12-hour night is sufficient to get cannabis plants to reach the blooming stage and mature in a respectable length of time.
- Learn more about how cannabis light schedules effect flowering However, some cannabis plants, particularly Sativa and Haze strains that originate near the equator, may require more than three months to fully flowering when grown under a 12/12 light cycle.
It can take that long for their buds to reach maturity. Sativa and Haze strains are often quite tall, and the blooming phase can last many months. Already enormous, these colas on a Malawi Gold (Chamba) plant have been flowering for over two months! However, they continue to show no indications of stopping! This strain may finish blooming in more than four months if grown on a 12/12 cycle! If you’re cultivating a long-blooming plant indoors and you want to “hurry it up,” one of the finest things you can do is limit the light period so that the plant has longer evenings.
As an illustration, you may provide your plants with 13 or 14 hours of darkness every day (11/13 or 10/14 schedule) to accelerate their growth. It “believes” winter is approaching and completes its task in less time. Give plants longer nights to hasten their maturation. As a result of providing your plant less hours each day, you will see a decrease in yields.
In addition, your plant will finish flowering sooner, therefore you will lose the weeks of flowering that would have increased to the ultimate weight of your buds. When is harvest time? Due to the possibility of reduced yields, it is advised to wait until the plant has been flowering for at least eight weeks before initiating longer nights.
