When to Flower Indoor Weed: How Long Should You Veg Your Crops?

Cannabis is such a beautiful plant. Growing it is easy, but bringing it to yield copious amounts of resinous flowers takes time and dedication. When growing weed indoors we are responsible for maintaining all aspects of our plants’ environment. Learn when to flower indoor weed for the best results.

Short Answer: 4-8 weeks

Long Answer: It’s complicated…

They say timing is everything. When it comes to cultivating cannabis indoors the sentiment couldn’t be more relevant. A great indoor grower has their operation completely in sync. When mature plants are getting harvested, veg plants are getting flipped to flower, and more clones are getting cut.

Most indoor growers are after a perpetual harvest. Forever growing ganja and harvesting beautiful buds is something of a commitment though. When it comes to achieving that balance in your indoor setup one of the most crucial aspects is timing the flip from vegetative to flower.

About the Vegetative State

It may seem somewhat rudimentary to explain what the vegetative state is. With laws on cannabis shifting though, there are a ton of new growers out there that are asking about the basics.

You’ll often here experienced cultivators referring to their plants by how many weeks they’ve been vegging. Describing a plant in its third week of veg gives some insight, but without context, it’s essentially useless, especially if you’re talking to a beginner.

Clones vs. Seeds

From clones, some say that the veg state begins once the clone is well rooted and has been transplanted, which is pretty accurate. From seed, some say the veg state is beginning once the plant breeches the soil.

Others say that it begins when the seedling has produced its first set of true leave. True leaves being leaves that look like marijuana leaves as opposed to rounded seedling leaves.

It doesn’t really matter how you define the beginning of the veg phase. What matters is the context of your setup. What method are you using to grow, a sea of green or full-term seed plants? Are you growing from clones or seeds and are you planning on super cropping your plants?

When we talk about how long we should veg cannabis, it really depends on numerous factors including:

  • Strain Genetics
  • Growing Style
  • Training Methods
  • Grow room size
  • Plant Health

Cannabis Grow Methods

Defining your veg time depends a lot upon the method of growing you’re implementing and the size of your grow space. When plants flip to flower they typically double in size, more or less.

If you veg your plants to 3ft. tall but there’s only 5ft. between the growing medium and lighting, you could find your buds getting burnt from the lights before they’re ready for harvest. Remember that and your veg time to be in accordance with your grow room size.

When to Flower Indoor Weed: Sea of Green

Growing in a sea of green requires minimal vegging. Plants in this method are flipped while small and pruned to grow one big cola or top. In a sea of green setup, plants are kept relatively short and many are packed into a small space in order to maximize production.

Plants should be switched to flower once they’ve reached six to twelve inches in height, which could take anywhere from 1-3 weeks of veg time. Indica strains will be better suited for this setup because they don’t continue vertical growth as much as Sativas do during flowering.

When to Flower Indoor Weed: Screen of Green

A screen of green (SCROG) is a great way to maximize horizontal grow and vertical space indoors. A netting or trellis is set up across the canopy at one to two feet above the growing medium. Plants are grown into the netting and the tops are trained horizontally into the trellis.

When your plants are tall enough to be trained sufficiently into the netting, you can then switch them to flowering. This could take anywhere from two to six weeks depending on how tall your netting is set, grow lights, and strain genetics.

When to Flower Indoor Weed: Supercrop

A super crop is essentially restricted to growing horizontally. Plants can be vegged until they’ve filled up your grow space. With super cropping, vertical space doesn’t become an issue because all of the plants are horizontal.

Depending on your grow space, vegging a super crop could take four to eight weeks. Similar to a screen of green setup, a super crop focuses on producing wide, bushy plants with multiple bud sites. As opposed to thick, vertical growth with big buds on top and larf underneath, a super crop, SOG, and SCROG, setup will maximize horizontal canopy space.

Conclusion

The best way to measure the moment at which you should flip your plants from veg to flower is by height. Most growers’ forums will give advice in weeks, but that’s just not really helpful without context.

Longer veg times means bigger plants, which means bigger buds. However, it also means more nutrients, more watering, and more time waiting for skunky nugs to be ready. Also, if you can’t manage large plants indoors, you’re wasting your time vegging out for two months and could jeopardize your harvest.

Consider you grow room size, strain genetics, and method of growing, and you’ll be able to easily figure out ideal veg time approximations. You’ll need to adjust your plans according to how tall and fast your girls grow too.

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.

Whats the minimum veg time from seed?

Can anyone tell me if there’s a minimum veg time from seed?I’ve been let down on some cuttings that i’ve been waiting on for 10 days but when i ordered the cuttings ten days ago,I planted 10 Big Buddha cheese seeds the same day just in case something like this would happen.
The seeds have been up a week now and are just forming their third full leaf(excluding cotyledons).I usually veg for six weeks or till the sex shows but I’ve got a week to ten days before my other grow finishes and was hoping to time it just right so that i had another ten girls ready to go into flower.That’ll make the seedlings around 2 1/2 weeks old and I reckon at the rate they’re growing they’ll have about six nodes by then.Is this too early and will it make a difference to the yield?

It’s always been my process that once I see alternating nodes, that seedings are ready to go under the big lights. There isn’t really a definitive time like 8.4 days, each variety is different, each setup is different.

I do think it will impact yield. If you let them veg for another 3 weeks, you’d see a significant increase in yield.
