how much does one pot plant yield

How much will an indoor cannabis plant yield?

Home Grower Question: How much does an indoor cannabis plant yield?

Answer: The answer is not easy, but it’s honest. Plant yields vary due to many factors including the size of plant, which is to say, how big you let your plant grow. The quality of the plant’s genetics and propensity for the genetic’s yield — be it a low, medium or heavy producing strain, also greatly influence yield.

Because indoor cannabis plant yields vary, there is no cut and dry answer to the question, “how much does an indoor cannabis plant yield?”

You see, it depends on whether you are growing small plants, medium sized plants, large plants, or extremely large plants. The size of your pot must be taken into consideration, and there can be a big difference in the size of your harvest (yield), depending on if you are growing in a grow tent or in a grow room with high ceilings.

Where and how you grow is a crucial factor to get to the bottom of your question, “how much does an indoor cannabis plant yield?” The strain you grow is also an influential factor. Additionally, you must consider how long you are growing your plant in the vegetative phase. People who grow cannabis plants with over 10 ounces are usually keeping their plants in the vegetative phase for more than 10 weeks. Do you have the time?

What about those one-size-fits-all answers online?

They often reference a yield algorithm based on things like how big your grow room is, what lights you are using, how many watts, and more. Not helpful. An answer like, “A grow room with 1200 watts can lead to a yield of 42 oz.” or “you can grow 1 lb. per plant,” not only sets false expectations, it confuses new cannabis gardeners who are trying to grow in grow tents with LEDs.

But that doesn’t mean you can’t figure an answer to this common question about plant yield indoors. There are a lot of moving parts in your gardening process that influence yield per plant. To get close to a perfect estimate, you’ll need to know if you are growing in a small tent, large tent, or in a grow room. If you are growing in a small grow tent, you may be growing small to medium size plants. You may have 6 short plants or 3 short to medium sized plants, 2 big plants, or you may have 1 “large as you can get it” plant.

Genetics, plant care, lighting, pot size, and your grow space all influence how much an indoor marijuana plant will yield.

Plant genetics greatly influences how much a plant can yield. You can grow a “heavy yielding” or “heavy producer” strain, average yielding strain, or low-yielding strain. For example, the size of cola buds on a Dream Queen strain are much bigger than the cola buds of a Girl Scout Cookies strain. If you are unsure of your seed or clone origin before growing, that is a big risk to take if growing for heavy yields is your goal.

Don’t forget “Plant Care.”

You can lessen your plants yield potential by not properly caring for your plant indoors. Plant care includes the quality organic nutrients and water it needs to survive and thrive. It may include plant training techniques like topping, pinching and supercopping, all to grow bigger plants. If you don’t practice proper plant care, you won’t get as much of a yield per plant.

Pot size matters!

Did you give your plant a 2, 3, 4 or 5 gallon pot, or a 10 gallon pot? The bigger the pot, the bigger the plant. Lighting is another key ingredient to increasing your plant yields. If you grow with a cheap LED Light, you’ll diminish the plant’s yield potential. You’ll want to grow with a high quality LED light to get the most amount of yield per plant indoors.

With all that said about indoor plant yields, home growers who grow marijuana plants indoors in grow tents may yield from 1 – 5 ounces per cannabis plant, with a sweet spot of 2 – 4 ounces per plant. Honestly it depends on the above mentioned gardening and genetic factors, but this gives you a realistic snapshot of your cannabis yield potential.

Lastly, if you have high ceilings in your grow room (or a emptied indoor pool), you are positioned to grow plants that may yield much more, like 6 – 16 ounces. There are 16 ounces in 1 pound. You could even pull 2 lbs. from a plant indoors if you really wanted, but it would take a significant amount of time in the vegetative phase and you’d need tall ceilings, and big pots. It is in the realm of possibilities! Our best recommendation to grow indoor plants indoors that weigh 2, 3, 4, 5, 6, 7, or 8 pounds is to grow in 100 lb. pots, and give yourself at least 4 – 6 months in the vegetative phase of plant growth.

Home growers who grow marijuana plants indoors in grow tents may yield from 1 – 5 ounces per cannabis plant, with a sweet spot of 2 – 4 ounces per plant.

How Much Do Autoflowering Cannabis Plants Yield?

There are several reasons a person may wish to grow autoflowering Cannabis at home, whether it be for taste, effect, medicinal value, or yield. The amount an autoflower can produce will be the difference between how full your curing jars get, and how successful you are as a grower.

Autoflowers can yield from 50-250g, but that can be affected by genetics, conditions, and nutrients, our top tips will help you get the most out of your autos!

1. What Does “Yield” Mean?

Yield refers to the estimated amount of buds produced and can be measured as dry or wet weight but after you’ve harvested, trimmed, and dry your cannabis plants, that is the final amount of dried buds and the official yield.

You will notice that seed banks will often display the yield in a square meter scenario, as opposed to the dried weight per plant. Not only can a figure such as “450-550gr/m2” be misleading, but there are also many variables that will play a factor in the outcome of this value.

2. Factors To Consider

The Weather

When growing autoflowering cultivars outdoors, the climate plays a massive role in the outcome of your yield.

Outdoor growers depend on the seasons to be able to get good yields from autoflowers, this happens because cannabis plants depend on the right temperature, humidity, and sunlight to thrive, and this will reflect on the quality and quantity of the buds you’ll harvest.

People who live in hot sunny climates will be able to grow autos all year long, with excellent results but those who experience shorter summers with a cold Winter may not harvest as much as someone in a tropical climate, however, they can expect to grow multiple times per year with superb results.

Now, when growing indoors you don’t have to worry that much about the conditions because you are responsible for controlling every single aspect of the growing conditions, this can be a good thing for more experienced growers but if you’re new to growing indoors, it can be quite tricky if you don’t have access or can’t afford the right equipment.

As you may know, cannabis plants need certain conditions in each stage of growth, but as a general guideline, you should keep the temperature between 18-24°C and the humidity should be kept around 70% in the vegetative stage, gradually lowering it until you reach 60% near the pre-flowering stage.

Then, when your plants are starting to form the buds, the humidity should be around 50%, reaching 40-45% at the end of the flowering stage.

Pot Size

Not everyone has the luxury of growing in a meter square grow space, and some must resort to a small, discreet plant count that can be kept on a balcony, terrace, or back garden.

Depending on where you’re growing your cannabis plants, you will have to choose either a bigger or a smaller pot and this will end up affecting how big your plants grow, and consequently, the yields.

For example, if you are growing large-sized plants in 10-12 liter-sized pots, you will be able to harvest 50-150g per plant as long as the conditions are optimum, so if you prefer smaller plants and use smaller pots, the yields will be decreased.

  • There is no need to grow autos in pots bigger than 12 liters.
  • Sea of Green requires a smaller pot size of 5-7.5 liters.
  • Planting directly into the ground is also a good option.

Nutrients Used

Supplementing your autoflowering plants with a rich source of N-P-K (macronutrients) and trace elements (micronutrients) is certainly one way to enhance production. Investing in organic nutrients or a complete living soil will be advantageous, as long as you maintain the ideal watering ratio.

This is because organic nutrients work different from synthetic nutrients.

Organic feeding consists of maintaining a good soil with beneficial microorganisms that form a symbiotic relationship with your cannabis plant, this way the fungi feed on the sugars produced by plants while they break down nutrients and retain water in the rhizosphere which makes it easier for your plant to absorb nutrients and hydrate.

On the other side, synthetic nutrients consist of feeding the roots directly, this means that you don’t have to maintain a healthy soil because synthetic nutrients can actually kill the microorganisms present, so despite being easier to feed synthetic, it’s easier to overfeed and end up burning your plants.

If feeding with synthetic nutrients, then follow the recommended guidelines when making your nutrient solution.

  • You will want to feed your autos only plain water for the final 2 weeks, to allow the plants to flush.
  • Some cultivars will be able to uptake higher amounts of a nutrient solution than others.

Plant Count

Another thing that will affect your yield is the number of plants you have in your grow space, you have the option to grow a few large-sized plants, or many smaller ones packed together in a Sea of green, each have their own advantages and disadvantages.

For example, if you’re growing in a 1m2 grow space you will have to choose between making the most of just one or two big plants or grow up to 6 smaller plants, this is up to you, obviously.

It is always a good idea to know in advance if you can grow a Sea of Green, SCRoG, or prefer to let your plants grow naturally.

Sea of Green

If you are choosing to grow many small plants packed closely together, then make sure the cultivar is well suited for that setup. You want to go for shorter plants that grow relatively homogeneous, this way you can fit in between 6-10 plants in a meter square, planting in 5-7.5 liter pots.


When growing in a SCRoG setup, you can go for whatever you want, obviously, you won’t be able to for 20 plants in 1m2 but because this technique consists of shaping your plants into a dense canopy, you can get away with growing from 2-5 plants in 7-10 liter pots. As long as you’re filling your SCRoG net properly, you’ll get a nice dense canopy and great results.

Big-Sized Plants

For some, it can be more practical to grow 1-3 bigger-sized plants, and for this, we recommend using a pot size between 10-15 liters to allow your plants to grow to their maximum, reaching up to 150cm in some cases.

Plant Training

When it comes to autoflowering cultivars, it is best to apply certain training techniques to different cultivars. This will encourage a much bigger and more productive harvest, exposing the plants to more direct light and increasing yields further.

We only recommend plant training if you can benefit from that or if you’ve had experience before because you can end up stressing your plants and that will have the opposite results, less plant growth, and lower yields.

There are two types of plant training, LST and HST, both of them serve growers to help modify and shape the structure of a plant to either make the most out of the light fixture or control the size of the plants if you have a limited grow space.

Low-stress training (LST) basically consists of bending or tying down the branches without mutilating the plants, as the name says, it’s less likely to stress your plants when compared to HST and it’s what its usually recommended for autoflowers but you can get away with HST if you know what you’re doing, have in mind that LST requires patience and more work when compared to HST because you are shaping your plants gently day by day.

High-stress training (HST) consists of mutilating your cannabis plants, either by topping, defoliating, or fimming, you will have the same results as when performing LST but you will have less work because once you’ve cut a part of your plant, the work is done.

  • Low-stress training means to tie the highest parts of the plant down, to create an even-growing canopy of large-sized buds.
  • It is best to avoid any type of plant training after your plants have started flowering.
  • Using a SCROG setup can increase yield and allow for a much more efficient growing space.

The Cultivar

If you’re a home grower and want to make the most out of each seed or if you’re a commercial grower and you prefer production before anything else, then finding the best genetics to aid in this job will give you the upper hand, obviously, growing the highest yielding autoflower is the way to go but there are basic things you should know.

There is a wide range of Indica and Sativa characteristics in hybrid autoflowering strains, with some being more rewarding than others when it comes to yield.

Now, don’t think that Sativa-dominant hybrids always yield more than Indica-dominant, even though Sativas grow more and consequently yield more, Indicas produce denser buds that, even though it might seem they produce less, they can end up weighing more.

So have in mind that although you should choose your genetics based on how much they yield (if you’re looking for high yields) you should choose a strain that better suits your growing style and your growing conditions.

Always keep in mind:

  • Some cultivars may take longer to flower and yield more than others.
  • Certain strains are better suited for cold and others for hot climates.

Gorilla Cookies Auto

Gorilla Cookies is not only a high-yielder but also a truly powerful strain, resulting from the cross between two resistant strains, you’ll be amazed by the quantity and quality of this great genetics which grows around 100cm and can produce up to 600gr/m2.

This plant grows quite compact and bushy, similar to Indicas but it actually is a fine-balanced hybrid that offers the best of both worlds, you can expect really dense buds with a beautiful color mix and a thick layer of resin that makes the buds shine from afar.
