Veg Yield Week by Week – Your Yield Cyclopedia!

Yield is one of the key methods to assess the plant’s growth. Unfortunately, it is one of the most difficult metrics to measure. However, with a bit of preparation, it becomes easy. Also, there are different methods and seeds to choose from.

So, you want to know about the growth of veg yield week by week

Plants grow yield during their flowering stage, which takes 8-11 weeks. The overall yield growth depends on two primary factors: the strain and the growing environment. On average, with indoor plants, you’ll get around 400-450 g/m2. However, you can get a maximum of 2000 grams per plant outdoors.

We know you’re curious to know about the whole thing. 

Let’s not waste any more time and get started!


  • You’ll get different results of growth and yield depending on indoor and outdoor cannabis strains.
  • Nitrogen is the key element to boost the growth in the vegetative phase.
  • Maintaining the temperature around 20-30 degrees celsius in the veg state yields excellent results.

Veg Yield Week by Week – The Flowering Stage

If you follow the proper methods, equipment, and care, you can get maximum yield. However, saying how much yield you’ll get without knowing about all the factors is impossible. It’s like telling how much a stomach takes to digest food.

There are a lot of factors like food type, quantity, quality, stomach acid, time, health, etc. You can’t just say my stomach takes 1 hour to digest foods, how much does yours take? That sounds ridiculous, right? Don’t worry! We’ve got the solution.

Now let’s quickly move onto the detailed flowering stage. We all know about two famous methods of growing cannabis. One is the Sea of Green (SOG) method and the other one is the Screen of Green (SCROG) method. 

Both of these two methods can be used indoors or outdoors. However, don’t forget about the growing conditions as well the factors. Also, keep in mind that some strains are recommended to grow using one particular method. 

So, make sure to know which method would be best for the strain you are using. For this week-by-week breakdown, we’ve taken 2 and 3-gallon pots. It is the ideal pot size experts use for these two methods. 

Before we jump into the topic further let’s answer a common question people ask. I bet you’re also having the same question: SOG vs SCROG, which one for highest yield?

The truth is no matter which method you use, the yields will be the same. In the SOG method, we use so many plants for a shorter vegetative time. However, in the SCROG method, the plants need to be veg for longer periods. Both methods have their own advantages and disadvantages.

Alright, now let’s get into the business real quick. We’re going to inspect the 8-11 weeks flowering stage in SOG/SCROG methods.

We have already discussed the high-yield indoor and outdoor strains. However, indoor vs outdoor yield calculation is different. For the outdoor plants, we measure yields per plant whereas for indoor plants we calculate g/m2.

Now check out the table below. It shows the flowering stage of the different plant strains in the indoor environment. The weekly breakdown shows the least to maximum yield growth for the different strains. 

Week by Week Table – Indoor/Outdoor and SOG/SCROG:

For this table we’ve taken the highest-yield indoor strains. Let’s take a look-

Note: The yield size completely depends on the factors we have mentioned earlier. So, keep in mind your plant’s yield may vary depending on those factors. Having said that, these weekly calculations are the average value of the maximum yield.

So, the tables show how much yield you can get based on the plant strain. Also considering other important factors like the methods, environment, vegetative period, and gallon size.

Most people find 2-3 gallons size ideal. However, larger plants may require 50 gallons for outdoor growing due to their deeper roots.

What are the Factors that Determine Max Yield?

Veg yield development has two primary stages of growth: the vegetative stage and the flowering stage. This article will focus on the flowering stage since we’re concerned about yield. Normally it takes up to 16 weeks for the veg for maximum yield.

However, there are some factors that directly affect the yield size. Indoor and outdoor environments are two determinant factors. For instance, the indoor environment will have a different effect compared to the outdoor environment. 

There are other important factors that determine the maximum yield growth. Such as the size of the pot and space, plant height, nutrients, indoor light, temperature, and strain. Now, let’s discuss the factors in detail below. 

Alright, now let’s discuss the factors one by one. We’ll go through all the factors and explain how they affect yield size. Let’s go.

Pot Size and Space:

Pot size definitely has a significant effect on yield growth. The size determines to what extent the yield has room to grow. The bigger the pot size the bigger the room for the yield to grow. However, a bigger pot size also makes maintenance harder.

Depending on your strains, you can go for 5-gallon pots or grow bags. Because its neither too small nor too big.

When you get big pots for your plants make sure they get the proper care. Big plants need regular care and maintenance Compared to bigger plants small plants require less care.  If you are new in this field we advise you not to grow bigger plants. 

Also, note that your plant size doesn’t determine the ultimate yield size. You may have some small plants and some big plants. But the small plants may produce a maximum yield than the big ones. Hence, ultimately the pot size matters rather than the plant size.

Plant Height:

Plant height is another determinant factor that needs consideration. Plants’ height and yield growth are correlated. The taller the plant is the deeper the roots will go.

That’s why plants with bigger heights require bigger pots. It makes sure that the growth doesn’t get thwarted. In addition, taller plants are more vulnerable to storms, wind, and rain. Hence, short plant plants are good compared to taller plants.


Just like we humans can’t survive without nutrients, plants can’t as well. There are three nutrients that are vital for the growth of plants. These are Nitrogen, Potassium, and Phosphorus.

We know that veg has two primary growth stages, the vegetative stage, and the flowering stage. These nutrients vary depending on these two different growth stages. Now let’s make it easy for you. Follow the table below. 

Growth StagesNitrogenPotassiumPhosphorus
Vegetative Stage9%6%3%
Flowering Stage3%4%9%

From the table we see, in the vegetative stage the plants need essential nitrogen supplements the most. Phosphorus is the least amount of nutrients needed for the vegetative stage. 

Likewise, In the flowering stage, the most needed nutrient is phosphorus or Triple Super Phosphate. The least amount of nutrients needed is nitrogen. Now, let’s move on to the next factor.


Light is another important factor that affects yield growth. However, lights are only used in the indoor environment. There are different light spectrums that affect yield growth directly.

For instance, using a 100-watt light to maximize yield growth of a particular strain. Likewise, some strains may need 600 watts. Hence, choosing the suitable one for your strain is crucial. 

Despite having the best-yielding strain, it won’t grow to its maximum potential without adequate lighting. We have found that using LED lights can provide you with the best results. 

Why is that? Check out these awesome benefits of LED lights-

  • LED lights produce less heat compared to HID lights.
  • LED light temperatures are under your control. They provide the ideal room temperature for the plants. The heat LEDs produced are ideal for planting environments. But if that doesn’t fit your needs, you can always control it.
  • LED lights have effects on the bud color. These lights are capable of bringing out more colorful buds compared to other lights.
  • Modern LED lights can provide a higher yield growth rate and better bud quality. Also, they help to produce more THC compared to the other lighting environment.


Plants need the right temperature for growth. Some strains need a particular stable temperature to be maintained always. If the cannabis plant temperature is too high or too low it can damage the plants.

According to our research, temperatures between 20-30 degrees Celsius are ideal for maximizing yield growth. Below or above that temperature can ruin the process.


Strain is another important factor, different kinds of strains have different growth stages. As a result, you should choose the right strain for maximum yield growth. Our study has found four strains that give the highest yields. Let’s check them out.

Highest-yield Indoor Strains:

These strains put out the highest yield when grown in the indoor environment with proper care and equipment.

StrainsAmount of THC%
Lemon Shining Silver Haze21%
Amnesia Haze 22%
Sweet ZZ27%
Blue Gelato22%

Highest-yield Outdoor Strains:

These strains show the best results when grown outdoors under direct sunlight. They’re also taller and need larger pot sizes compared to indoor strains.

You can simply follow this table when selecting a plant strain. After you select a strain, move to the week by week table for the breakdown.

Frequently Asked Questions (FAQs):

How Do You Get Big Yields Outdoors?

To get a big yield outdoors, first, select the suitable strain based on genetics. Secondly, train the plants, and choose low-stress or high-stress training accordingly. Thirdly, use beneficial bacteria as microorganisms. Lastly, use felt pots to provide room for maximum root growth.

Does Longer Veg Mean More Yield?

Yes! The more time you spend in the vegetative stage the bigger the plants will grow. And guess what, bigger plants mean bigger yields. That’s why most people grow plants outdoors in direct sunlight because it reduces light costs. Also, it requires comparatively less effort.

Are 4 Weeks Veg Enough?

4 weeks veg is enough for the smaller plants. Usually, small cannabis is capable of flowering after 4 weeks. However, big plants require at least 8 weeks for flowering to begin. So, if you have a small plant or a couple of small plants, 4 weeks of veg is enough.

The Bottom Line

We’ve reached the bottom of the article on veg yield week by week. Let’s have a quick recap. We discussed the flowering stage of 4 different best-yield growing indoor and outdoor plants. Also, we have provided the yield’s growth from 8 to 11 weeks.
