How Long To Veg Weed From Seed

It’s important to care for your plants when they move to the vegetative phase from the seedling phase. So, knowing how long to veg from seed is essential. Read more to know about it in detail. The cannabis vegetative phase is crucial as your plants prepare for flowering. Know the average veg time and what they need at this stage. The germinated seeds peak out above ground and immediately spring up into small, blade-like green plants.

How Long To Veg From Seed

The vegetative phase is one of the most important stages of growing cannabis. It takes place before flowering and after seedling. There is a lot you should know about when you’re growing cannabis no matter it’s indoor or outdoor growing.

And, it’s important to know how long to veg from seed as well. Because the number of yields and how you can maximize the yields are dependent on knowing the ideal duration of every stage.

Chances are you are here to know the ins and outs of the vegetative stage and how you should treat your plants in this stage. Well, then you are in luck because today, we are going to share some information that every grower must know.

We will talk in detail about the seedling and vegetative stages of cannabis plants and share some additional tips that you will find helpful while growing cannabis. Also, there is an FAQ section to vanish your confusion regarding this topic.

Well, enough beating around the bush, let’s just get to the point.

How Long to Veg From Seed

The one-worded answer is 3-6 weeks. Yes, the plant will be in the seedling anywhere between 3 and 6 weeks. Although it depends on which particular strain you cultivate and the environmental factors as well.

The seedling process will grow by destroying the seed coat. Meanwhile, the root systems at the plant’s base will start developing. Moreover, the leaves will start spreading out.

Your plants will step into their very first true growth cycle when new leaves grow. At this time, your plants will be growing until the flowering stage starts.

Seedling

A healthy seed takes around 3-7 days to grow into a seedling. And, this stage will start only when the plants develop a stable root system as well as the beginning of growing ‘true leaves’ (true leaves are leaves that come with the same characteristics and forms of a mature cannabis leave).

Remember, you must pay attention to your plants all the time. Most importantly, the plants need much attention in the early stages of their growth and on the speed of developing foliage.

Your plants will transit into the vegetative stage once they start developing a stale root system and foliage. And, this is more important if you plan for transplantation. Because this is the right time to transfer your seedling to a new environment or container if you had been planning for it.

Some useful tips you should follow during the seedling stage:

  • Maintain proper humidity
  • Try to keep the temperature at 77°
  • Control the number of nutrients

Now, you may ask, what’s wrong with the nutrients? Well, for your kind information, nutrients may burn the seedlings of your cannabis. However, if you have to use fertilizers, use them in moderation. And, it’s a good idea to use fertilizers that contain Nitrogen.

Right after you notice the cotyledons, you need to set up white light for 18 hours a day. Try to keep the temperature somewhere between 68 and 77°. And, when it comes to humidity, it should be around 60%.

You can use CFL lights for your seedlings as they will not produce too much heat. You can keep 2 inches distance between the seedlings and the lights that will make sure of providing them plenty of light.

Vegetative Stage

And, now, your plants entered into the awaited vegetative stage when your plants come into their own and produce big leaves. In this stage, plants produce way more leaves since they absorb much more nutrients including Carbon Dioxide.

Not only the leaves but also the roots will keep expanding which will grow your plants taller. If you’re dealing with healthy plants, a single plant will grow up to 2” in a day.

In the primitive stage, you can control the vegetative stage by light exposure. And, if you are an outdoor grower, then, what part of the world you do live in will matter. If you are an indoor grower, you can keep the plants in the vegetative stage for as long as you want though generally, it lasts 1-2 months.

In this stage, there are a lot of happenings of the plants. For example, your plants will grow leaves and stalks. It creates a solid structure for supporting heavy buds. There will be adding new layers of leaves as well as the plants will grow larger and taller.

And, this is the time when you can recognize the cannabis varieties and notice the difference between them.

Hence, you should maintain the temperature properly by keeping them somewhere between 68 and 77° with the supply of white light (for 18 hours a day). And, make sure the humidity is around 50-70%. About the fertilizers, you should stick to the nitrogen-based ones.

The vegetative stage will last around 1-2 months.

How Vegetative Growth Time Affects the Yield

Does vegetative growth time affect your yield? If it does, then how?

Yes, two factors that increase yields are- veg time and light. So, yes, how long to veg from seed is an important question to ask. And, what about the brand of nutrients? Well, this is important as well, but we can keep it 5th on our list.

You may find it surprising that no matter, if it’s from seed or clone, doubling the veg time, can triple your yields. If you add 2 weeks to the veg time, you can get your double yield.

Since there’s nothing come without drawbacks, so the increased veg time is. A longer vegetative time will take more time and lengthen the growing schedule, as well as there will be more time to make a mistake along the way.

Ultimately, the thing is, the longer the vegetative stage is, the bigger the yield will be.

And, the vegetative stage should last 1-2 months. So, if you ask now, is 4 weeks veg enough? We would say, you know the answer, my friend!

Light Cycle of The Vegetative Stage

As we said before, there are a lot of happenings in the vegetative stage, you need to know about the proper care for this stage.

Although it’s standard to keep the plants under grow lights for around 18 hours, if you want them to grow as big as possible, you can keep the plants 24 hours under the growing lights.

However, your plants will not start the flowering stage until they start getting 12 hours of constant darkness. Or, the plants will be remaining in the vegetative stage.

Indoor Vegetative Stage

When it is the vegetative stage, it’s not only light that grows large cannabis plants. And, when we’re talking about indoor vegetative stages, it’s also important to have a well-maintained grow room that comes with a high ceiling.

Something worth mentioning here, there are some strains such as Jack Harer and Northern Lights that can grow high-yielding crops without those manipulations.

Outdoor Vegetative Stage

Before you move the cannabis plants outside so that they grow under the sun, you would keep them indoors under lights. You can either start seeds or cut clones in March or April. Moreover, you would keep them under lights for 18-24 hours before you move the plants in May or June.

Therefore, if you want to grow the plants outside, it’s a good idea to keep them inside so that any kind of danger such as frost has passed. A big change in the environment like snowfall or a sudden fall in temperature may kill your plant outright.

However, once the risks are gone, your plants still will be in the vegetative stage outdoor. And, the duration is from spring to late summer.

Clone Vs Seed How Long to veg for better yield?

Although there are a lot of advantages of growing your cannabis from seeds, they require a longer period to reach harvest time compared to clones. It takes up to a week to show the very first signs of life from the soil.

And, do you know how long does it take for seedlings to mature? They take around 1-2 weeks. So yes, add another week more. You may not find it too long, however, speedy auto-flowering strains are way too popular.

On the other hand, clones save time because you don’t have to wait to think when a seed will germinate or grow into a fairly sized seedling. All you need to with a clone is to root your cutting, and your plant is totally ready to grow!

However, if you want to know whether seed or clone will provide you with better yields, then there are a few factors to talk about. Such as:

  • Seeds are really easy to access, but clones are a bit tough to access for home growers.
  • You can simply throw the seeds into the soil and they are okay with it. But you need to be very much careful while handing with the seeds.
  • There’s a risk whether seeds will germinate or not, with clones, it’s risk-free.
  • Clones save time whereas seeds take much time.

So, if you ask whether seeds or clones to choose, the answer is, it depends. We have pointed some factors here, now, you decide which one is the right fit for you.

Tips for Maximum Yields

Scheduling the light cycle properly can maximize your yield. If it’s indoor planning, during the vegetative stage, you should remain the plants under grow lights for 24/0 or 18/6. You should continue it for around 60 days which is the ideal time for growing more flowers.

And, if it’s outdoor planning, schedule your light cycle for cannabis for either 18/6 or 24/0. But the most important thing here is, you should keep the plants inside for a while and wait until the unfavorable conditions (e.g sudden drop in the temperature) have passed. Once passed, you can bring the plants out as well as let them grow under the fresh, open atmosphere.

When Do You Need to Re-Veg a Cannabis Plant?

There are some particular reasons why re-vegging a harvested plant. For example, in case, you think that you need to preserve an exact replica of a certain phenotype that may transition into its flowering stage, re-veg is the only option left.

If you need to reduce the vegetative period for any reason, you can re-veg the cannabis plant. Also, re-vegging offers bushier and more vigorous plants. So, you can also increase lant yields by re-vegging them.

Average vegetation time when growing cannabis plants

Although cannabis earned the nickname ‘weed’ because it can grow in most locations and under a wide variety of climate conditions, cultivating cannabis plants is much more complicated than the average person would think.

This article will discuss the vegetative stage, average veg and flower time for cannabis, and everything you will need to do, from lighting, watering, and feeding to keep your plants strong and healthy as they enter the flowering stage.

The vegetative stage of marijuana plants

Once a cannabis plant germinates and develops its first set of leaves on a relatively sturdy stem and root system, it enters the vegetative phase.

This is what most people consider the first stage of life for the cannabis plant. This phase is when the plant concentrates on growing big and strong in preparation for the flowering phase.

The average veg time for marijuana lasts between 4-18 weeks, depending on how big you want the plants to grow and how soon you would like them to start flowering.

During the vegetative stage, the plant will concentrate on growing and strengthening its foliage, stems, and roots.

This prepares it for carrying heavy buds once it flowers.

As the stem, roots, and foliage grow rapidly, you will have to adjust your watering, feeding, and lighting habits to ensure the plants get the right amount of light and water.

For instance, you should start watering further away from the stalk as the plant grows and the roots spread out to ensure it gets enough water.

Keep in mind; the flowering stage can begin as early as four weeks. However, the cannabis plants will most likely be small, and the buds they yield will be equally small. Ultimately, it’s going to be a trade-off between making the plants flower early but getting smaller buds or waiting a few more weeks for them to grow bigger and stronger and grow larger, denser buds. Since the marijuana plant’s life cycle is greatly determined by how much light it gets during the day, you can trigger early flowering in photoperiod plants by adjusting the lighting schedule.

How long is the average cannabis vegetation time?

The vegetative cycle is crucial for the cannabis plant’s life cycle, especially if you’re looking to harvest resinous buds rather than seeds for later cultivation. The plants will need to develop healthy leaves coupled with a strong, sturdy stem and root system to photosynthesize sunlight and support big, heavy buds’ weight.

The average veg time will last anything from 4 weeks to 8 weeks; however, you have some control over this with photoperiod plants. Let’s have a more in-depth look at what happens during the vegetative stage:

Once a marijuana seed is planted, either in the ground or some sort of container, it takes around 2-3 weeks to germinate and become a seedling, after which it begins vegetative growth. During this stage, the seed will develop a tap root, its first set of fan leaves, and a complete set of leaflets. Before you transplant the plants to a larger container or the ground, you may want to remove any stunted seedlings or seeds that haven’t fully germinated to prevent them from competing with the healthier plants for resources.

Now that there are leaves and a taproot, the taproot will drill downwards, looking for water while the leaves absorb sunlight and photosynthesize, furthering the growth process. If you would like to start training or topping the cannabis plants, the vegetative phase is the best time to do it. As the plant develops lateral roots that grow outwards in search of water and nutrients, start watering your plants further away from the stalk to ensure the roots stay hydrated.

If you are growing outdoors, make sure you plant the cannabis in healthy, nutrient-rich soil to support the rapid growth of the vegetative phase. You can also supplement this by adding nutrients to your plant’s water. For hydroponics or liquid nutrients, make sure you check pH levels and ensure they are at an optimum level (6.0 – 6.5).

Controlling the light cycle for indoor grow setups

Now that we know the average veg time for cannabis let’s get to the good stuff, lighting.

Growing your cannabis plants indoors gives you much more control over them, especially in terms of lighting.

These plants are extremely sensitive to light.

The levels of light and darkness provided during the vegetative phase determine how quickly your plant progresses to the next stage of development.

On average, cannabis will need 18+ hours of light per day during the vegetative phase.

Remember how changing the light cycle can force the plants to start flowering?

Well, as long as your indoor cannabis plants receive 18 hours of sunlight and 6 hours of darkness per day, they will remain in a vegetative state, growing bigger and stronger every day without developing any buds or flowers.

Once the plants start getting less than 12 hours of light per day, they start flowering.

However, you will have to provide just the right amount of light during this stage as too much will damage the plants, while too little light will impact the rate of photosynthesis and plant growth.

Concerning average veg time, indoor cannabis grows will largely depend on how soon the grower would like them to start flowering.

If you want bigger plants and heavier buds, you will have to wait a couple more weeks to let them stay in the vegetative phase.

However, if you don’t mind smaller plants and lighter buds, you can force them to flower early.

WHAT IS THE VEGETATIVE PHASE?

The vegetative phase is a period of the growing cycle that takes place after germination and before flowering.

After your cannabis seeds germinate, they’ll emerge from the soil as seedlings. These youngsters feature a short stem and two rounded cotyledons. Eventually, the first “true” leaves will form. Over the subsequent 2–3 weeks, seedlings will start to mature and produce a large number of fan leaves—structures required for photosynthesis. This marks the beginning of the vegetative phase.

The vegetative phase can last anywhere between 3–16 weeks (or longer), depending on the genetics of a cultivar and the goals of the grower. Explosive growth occurs during this time. Plants are typically transplanted into larger containers at the start of the vegetative phase to give their root system more room to expand. The main stem will ascend, and the space between nodes will increase dramatically. Indica cultivars will remain short and put out lots of lateral growth, whereas sativa varieties grow taller with much less ramification.For photoperiod varieties, the vegetative phase ends when the light cycle shortens.

  • Outdoors, this happens as the seasons change from summer to autumn.
  • Indoors, the lighting schedule is shortened to force photoperiod plants to flower on command. Plants will transition from the vegetative phase into bloom when exposed to a light cycle of 12 hours on and 12 hours off. In contrast, autoflowering cultivars initiate flowering based on their age as opposed to light cycle.

IMPORTANCE OF THE VEGETATIVE PHASE

The vegetative phase is a vital period in the life cycle of a cannabis plant. Growers need to provide optimal environmental conditions for their plants to grow as large and healthy as possible. Size often equates to yield. The bigger plants become, the more nodes or “bud sites” they develop, and the more flowers they’ll be able to produce. But size isn’t the only factor.

Some growers prefer to keep their plants small while still achieving excellent yields, which can be done by training plants. These techniques need to be implemented in the vegetative stage before the first flowers begin to emerge. Many essential physiological functions are underway during the vegetative stage. Fan leaves are working hard to convert light and CO₂ into energy. The root system is expanding and providing a firm anchor to prevent the plant from toppling over; the roots also work to uptake vital nutrients and water. To meet the demands of plants during this time, growers need to ensure they provide the correct amount of light, water, and nutrients.

Cultivators also need to be aware of pests and pathogens, and do their best to prevent these threats from damaging or even killing their crop. Ultimately, the vegetative period sets the stage for flowering. The healthier plants are during this time, the more prepared they will be for flowering and a bountiful harvest.

HOW TO ACHIEVE IDEAL VEGETATIVE GROWTH

The factors mentioned above apply to every cannabis grow. When cultivators manage to strike the perfect balance between all of these variables, remarkable growth becomes possible during the vegetative phase. Although the primary demands of plants remain the same, growers need to be aware of the differences between growing indoors and outdoors. These two very different environments present growers and their crop with various challenges.

INDOOR

Growing indoors usually involves raising plants in grow tents or dedicated grow rooms—this comes with distinct advantages and disadvantages. Indoor growers have almost complete control over the environment during the entire duration of the growing cycle. During the vegetative phase, they can elect to run lights for 18–24 hours per day. The more light a plant is exposed to, the more it can photosynthesise, resulting in more explosive vegetative growth. More control means there’s also more to manage. Indoor growers need to measure CO₂ levels, humidity, and temperature regularly. These factors need to be kept within specific parameters to optimise plant growth. Growers may need to invest in fans, hygrometers, humidifiers/dehumidifiers, extractor fans, and more to keep their operation running smoothly. These systems can be automated using timers and sensors, but this isn’t realistic for amateur and hobbyist cultivators.

Vaping boasts the same speed of onset as smoking. However, these devices use lower temperatures and expose users to fewer toxins.

OUTDOOR

Outdoor growers have much less control over their plants during the vegetative phase and the growing cycle as a whole. The elements take control, which can be a good thing in some circumstances. You don’t have to provide a light source, and frequent rain and irrigation systems remove the need to water regularly. Achieving ideal vegetative growth outdoors mostly lies in boosting your plants’ defences. There are a lot of critters out there that will happily chow down on your plants for lunch. Small creatures such as insects can burrow into leaves and munch into roots, whereas animals such as birds and deer can do some severe damage to leaves and stems. Humid environments also increase the risk of fungal infections. Biological controls such as predatory insects can be introduced to the garden to eliminate pest species, and companion plants can be grown to deter them. Netting and fencing are an effective line of defence against larger animals. Foliar sprays can help to keep mould away. Growers should also place their crop in an area of the garden that receives good airflow, and avoid stagnant areas.
