But how much weed does one plant produce? Check it out! This article will help you to decide on how much weed can you grow with one seed and when is the best time storing your marijuana seeds a cool place.
How much marijuana can I yield per plant? A pound!
Unfortunately, there are no simple answers to these questions. Every grow is different and has different variables.
Whatever your reasons for growing are, you care about the yield. You want to know what to expect, and that’s reasonable.
I can’t predict your experience, but I can give some reasonable numbers to strive for.
This article will discuss everything there is to know about marijuana yields.
I’ve added some common questions at the bottom, but if you have more, place them in the comments below this article.

How much marijuana can you yield indoors?
Lights are of the utmost importance when you’re growing indoors. Experienced growers can produce about a gram of marijuana per watt of light (1 gram = 0,035 oz).
So, a 400-watt HPS grow light can potentially translate to 400 grams or 14 oz of dried, usable cannabis.
Likewise, a grow room with 1200 watts of light can yield 1.2 kilograms or 42 oz of cannabis.
Having the right equipment, adequate nutrient solutions, beneficial air quality, and other valuable factors is important for producing the highest yields possible.
Making sure the plants have space to grow is also key.
Although soil growing can potentially lower your yield, it also is easier to grow. This is because it not only creates a buffer for error, but it also holds nutrients within the soil.
“Using your indoor space more efficiently can give you twice as much growing area.”
When growing in soil, there is room to make mistakes with pH and TDS and pay for it in yield. In terms of numbers, expect a maximum of 1 gram per watt. That means a 600 watt lamp can produce 600 grams of marijuana or 21 ounces.

Do hydroponics yield more?
Growing hydroponically yields up to 20% more, as long as you do not make any mistakes. With hydroponic growing, there is no room for errors.
You must be very careful about the TDS and pH levels because the roots are directly in water (and not soil) and incorrect levels can immediately affect the plants.
There are rarely small mistakes while growing hydroponically. Even the most minor error can ruin your yield. However, those who do it correctly will be rewarded.
You can expect up to 1.2 gram per watt, which means a 600watt HPS lamp can give you 720 grams of marijuana or over 25 ounces.

Start with high-yielding strains
Ideal circumstances are very important when trying to maximize your crop. But there’s no fault in helping yourself a bit by getting decently yielding genes. These strains fall under the category extreme yielders:
One of the most popular marijuana strains in the U.S., it’s your ideal start for a relaxing and invigorating day that later eases you into an easy euphoria.
- 20% Indica 80% Sativa hybrid
- High THC levels up to 21%
- Consistent heavy yields
- Easy going high for everyday use
- Feminized seeds for guaranteed bud
The name says it all. This strain grows huge buds which in turn yields great amounts of dry herb.
- 60% Indica 40% Sativa hybrid
- Feminized seeds for guaranteed bud
- Known for its easy to grow high yield
GSC is a very popular strain and nothing to sneeze at. This Extreme version of the strain yields huge flowers.

Average marijuana plant yield outdoors
Under perfect conditions, you can expect yields to extend to 500 grams or 17.5 oz of marijuana per plant.
Space is a necessity (at least two meters) along with water, nutrients, and a dearth of pests and diseases. If you use containers, they should be at least 50 liters or 15 gallons in size.
It’s a good idea to germinate the seeds early on to allow the plants time to grow large.
It’s best to germinate indoors where you can manage the humidity and the temperature for the seedlings. Again, 500 grams (17.5 oz) per plant is possible if everything goes as planned.
Aside from an adequate amount of sun, water, and nutrient quality, the actual genetics of the plant play a very important role.
Seeds are vital, and you need to have some exceptional seeds at your disposal. Browse my seed selection to find the strain that’s right for you. It all starts with genetics….
How to calculate marijuana yield
Want to predict your field before you grow? It doesn’t have to be a guessing game.
How much weed does one plant produce?
Try using a cannabis plant yield calculator. This calculator by Yield O Rama lets you select your type of light, the light intensity (lumen), your level of growing experience, and your growing medium.
Annual target & consumption projection
Days spent growing crops
Greater than 365: you will not meet your annual target (readjust your target settings or growing scenario).
Exactly 365: you will meet your annual target, growing continuous back-to-back crops for the entire year
Less than 365: you will meet your annual target, growing intermittently with some free time between crops.
When using the yield calculator, keep in mind that an HPS grow light produces around 150 lumens per watt. For the exact amount of lumen that your bulb produces, check with the manufacturer.
There are some limitations:
You cannot adjust it for the strain, and it’s only for indoor grows, but it is still quite handy. Check out the cannabis yield calculator here.
You can also measure your yield after you harvest but, keep in mind…
Wet and dry weed does not weigh the same
Drying your weed slowly (10 to 14 days) in a climate-controlled dark and dry place with a temperature of around 64 degrees will get you more weed in weight.
You will get about 20 % to 25 % out of your wet weed after drying, depending on the strain, the density of the buds and the way of drying. Only weigh the wet buds and not the whole plant.
Here’s an example.
Out of a well-cultivated Sativa you will get approximately 20% -22% dry weed and from an Indica about 22% -25%.
So out of one-pound wet Amnesia Haze you will get approximately 7.4 ounces and if you dry one pound of White Widow you’ll get about 8.4 ounces. At a street price of $ 7 (Oregon) or $12 (Texas) this is a very good profit.
On the other hand:
You will end up with approximately 12.5% if you weigh the entire plant, including stems and leaves, while it’s wet.

Grow fewer cannabis plants to yield more marijuana
Indoor growing doesn’t bring a lot of certainty in terms of yield per plant. If you have only four plants per lamp, then you’ll yield much more than you would with a total of sixteen plants for every lamp.
Before deciding how many plants to grow
Consider these facts:
- If you’ve only got 4 plants, your marijuana plant yield will be 25% less if one gets a disease or dies
- Vegetative growth lasts longer with only four plants. You should want to force flowering when the tips of the leaves are touching. If there are more plants, the leaves touch quicker
- Four plants are easier to manage than sixteen
- If someone catches you, you only have four plants to your name
Think about this:
Grow sixteen plants under a 600-watt HPS lamp and produce about 37.5 grams or 1.3 oz of marijuana per plant.
Grow four plants using a 600-watt HPS lamp and yield about 150 grams or 5.0 oz per plant.
But grow one huge plant per 600-watt HPS, and you could produce a pound of marijuana per plant!
Yield more with Screen Of Green
The Screen of Green (SCROG) technique is an excellent way to increase your yield. The idea is to top your plants and place a screen at 15 inches above your plants.
Be sure to check out aPotforPot for a one-stop solution for a small grow!
When a branch grows 4 inches through the filter, tie it to the screen horizontally. Continue attaching the branches until you get a nice ‘blanket’ of tops.
Now, three reasons why growing with a screen of green technique increases your yield:
1. No wasted light
Any light that hits the floor or walls is wasted energy. With the SCROG method, you create a thick ‘blanket of leaves’ out of your plant that prevents light from being wasted, and instead forces it to be absorbed by the leaves.
2. All plants are the same height
When every plant is the same height, each will receive the maximum amount of light.
With this method, there are no plants or branches in the shade, and you can place the lamp as low as possible, as long as temperatures don’t exceed 77 Fahrenheit.
3. No fluffy or soft buds
Because you prune the bottom branches that don’t grow through the screen, the plant doesn’t waste any energy on developing the small, soft buds at the base of your plant.
(FYI, they never ripen.) Your plants also don’t waste energy on leaves and branches it doesn’t need. All of its energy goes to the top colas!
Here is a photo guide on how to SCROG:
I’ve used the screen of green method for many grows, and I’ve always been satisfied with the results. If you use it, your yield can increase by 10 to 20%.
Lights make the difference for indoor grows
Does a 1000-watt HPS yield more than a 600-watt HPS?
Well, not necessarily. While a 1000-watt HPS bulb produces much more light than a 600-watt bulb, a plant cannot convert all that light into energy. It will need more CO2.
There is around 350-400 ppm of CO2 in the air. Indoor marijuana plants will use this CO2, combined with energy from the light to create sugars.
If you grow in a closed grow room without an air inlet, the plants will use half of this CO2 within an hour and then slow down sugar production because CO2 levels are dangerously low.
This is why you must continuously ventilate your grow room with fresh, CO2 rich air from outside.
With 350 to 400 ppm of CO2 in the air, your marijuana plants cannot create more sugars than the light from a 600-watt HPS bulb produces.
So your yield will not be higher if you use a 1000 watt HPS lamp under normal circumstances.
On the other hand, if you increase the CO2 levels, your plants will need more light, and in that case, a 1000-watt bulb can almost double your yield.
It’s a large investment to buy the right equipment, but a 1000 watt grow light is worth it in terms of yield.

Average indoor yield with CFL & HPS
Keeping the impact of CO2 in mind, there are some numbers that you can expect when growing with CFL and HPS lighting:
1.5 to 2.0 oz average (3.5 oz for advanced growers) with 200-watt CFL lamps in a grow cabinet measuring 3.5 x 1.5 x 6.5 ft.
3.0 to 5.0 oz average (9.0 oz for advanced growers) with a 250-watt HPS lamp in a grow cabinet measuring 3.5 x 1.5 x 6.5 ft.
4.5 to 9.0 oz average (14 oz for advanced growers) with a 400-watt HPS lamp in a 3.5 x 3.5 x 7 ft. grow room
5.0 to 10 oz average (21 for advanced growers) with a 600-watt HPS lamp in a 4 x 4 x 8 ft. grow room
9.0 to 18 oz average (36 for advanced growers) with a 1000-watt HPS lamp in a 5 x 5 x 8 ft grow room
40 to 60 grams average (100 for advanced growers) with 200-watt CFL lamps in a grow cabinet measuring 1 x 0.5 x 2 m
80 to 150 grams average (250 for advanced growers) with a 250-watt HPS lamp in a grow cabinet measuring 1 x 0.5 x 2 m
100 to 250 grams average (400 for advanced growers) with a 400-watt HPS lamp in a 1 x 1 x 2.5 m. grow room
150 to 300 grams average (600 for advanced growers) with a 600-watt HPS lamp in a 1.2 x 1.2 x 2.5 m. grow room
250 to 500 grams average (1000 for advanced growers) with a 1000-watt HPS lamp in a 1.5 x 1.5 x 2.5 m. grow room
LED grow yield
There has been much said about LED lights, with many manufacturers claiming super high yields, but I haven’t seen them yet.
I’ve tried a 300-watt LED grow two years ago and generated less than half of what I usually produce. Many of my friends also haven’t received desired results.
An interesting fact is that commercial tomato growers haven’t switched to LED. For me, that’s a sign that they’re no better or more economical than HPS grow lights.
With LED, the light intensity isn’t as strong as with HPS lights. Instead, the spectrum is more important.
So, I can’t tell you how much you will yield with a LED grow light. If anybody has some results, please share them in the comments.
I can confirm that LED lights produce a lot less heat compared to HPS lights. This will cause the plant to evaporate less water, changing the water and nutrient requirements for growers.

Save money by growing marijuana
A store-bought marijuana plant will cost around $10 to $15. It will be a clone of around 5 inches tall, and they’re only available in the states that have legalized marijuana.
High-quality marijuana seeds cost between $8 and $15. They’re available all over the internet and of course in my own store
But these figures do not cover the cost of producing weed. You need to buy equipment, nutrients and keep an eye on the electricity and water costs.
Below are some estimates, but read my article on costs and revenues for more details.
Growing 5 marijuana plants in a 2×2 foot grow tent with 2×100 watt CFL will cost you around $1000 per year and yield 0.25 pound of marijuana per harvest. With 4 harvests per year, each marijuana plant costs about $50.
Growing 5 marijuana plants in a 4x4foot grow tent with a 600 watt HPS light will cost you around $2000 per year and produce 1 pound of marijuana per harvest. With 4 harvests per year, each marijuana plant will cost around $100.
Equipment like filters, timers, and exhaust fans are very expensive. The price difference between a setup for 2 or 4 lights is only 20% higher, but the yield doubles.
Again, here you can learn more about the costs and benefits of growing.
You could be saving money, especially if you yield a pound per plant!
What does a 1 pound plant look like?
If you want to grow a one-pound marijuana plant, grow a single plant.
You need a 4 x 4 foot grow tent or other similar-sized space, and a 600-watt HPS grow light.
Under ideal circumstances, a 600 watt light can produce well over a pound of cannabis. If you limit your grow to just one plant, it can produce over a pound of weed.
You have to prune and trim your plant a lot otherwise it will grow through the ceiling. Scrogging is the way to go to cover 10 square feet with one plant.
Growing a one-pounder is a fun project, but there are some downsides. You need to veg the plant for very long until the entire floor is covered with leaves, so no light goes to waste.
Plus, if your plant gets sick or anything, you don’t have replacements. But it can be done!
Want to feature your 1-pounder indoor plant on our blog? Send me a picture!
Whether you are growing indoors or out, you can effectively plan for how much weed you’ll yield. In some cases, you can even grow a pound per plant.
It’s all about planning your grow setup and using the right grow techniques. You can predict your yield with a calculator or wait and weigh it after the harvest.
However you decide to grow, you’re likely to save money over buying it at a dispensary.
So, how much does Gold Leaf yield?
Gold Leaf is my very own, proudly bred, strain, and I must say; it is a very decent yielder!
As you now know, topnotch-conditions should apply but I’ve managed to cut about a pound of the plant grown indoors and it has even treated me to almost 21oz when I had it growing outside!
How much weed does one plant yield
One question on every beginner grower’s mind is how much does one marijuana plant yield? On average, a plant will produce 907.2 grams, or 32 ounces, of wet weed. For dry weed, you could get an average of 181.4 grams or 6.4 ounces.
Nevertheless, the yield size of each plant will be different from one another. You could harvest less or a lot more. When you are growing a cannabis plant, various factors can determine the amount of your yield. Elements such as genetics and training can propel you to a bountiful harvest.
How to Estimate Weed Yield?
There are two ways to masure yield.
1. Masure yield by the strenght of grow lights
One way to estimate the yield is by measuring it relative to the strength of your grow lights. Fortunately, the calculation is easy to do.
To measure it, calculate the total weight of the dried weed in grams. You could do wet weed, but it loses weight as it dries into the final product. Then, divide that weight by the bulb’s wattage. Here is a better visual of the formula:
Total weight of dried weed ÷ Watt = Yield size per watt
If you are using more than one lamp to grow the plants, add all the watts together. For example, two 400W bulbs would be 800W. If one plant produced 100 grams of cannabis, the calculation would be 100g/800W = .125g/W.
2. Masure yield by cubic feet
Growers also can estimate the yield of a plant relative to the size of its container. To start, you should calculate the volume, or cubic feet, of the pot. Multiply the surface diameter by the diameter across the bottom. Then, multiply the number by the vertical height.
Divide the dried weight by the cubic feet of the container. The formula would be:
Total weight of dried weed ÷ Cubic feet of the pot = Yield size per cubic feet
For example, a plant has 100 grams in dried weight, and the pot is .59 cubic feet. 100g/.59cu ft = 169.49 g/cu ft.
Factors That Determine How Much Weed one Plant produces
You can influence how much you harvest to a degree. Some aspects of marijuana cultivation contribute to yield size. The factors that come into play are:
The genetic quality of a weed seed can provide the future plant with various potential traits. One of those traits can impact the yield size of cannabis. There are three main species of marijuana plants: sativa, indica, and ruderalis. Growers tend to stick to sativa and indica, but a sativa plant is better for harvest size.
It is not uncommon for people to create hybrid strains. Hybrid plants can have attributes that maximize yields on top of increasing the aroma. The type you might want to consider using is a feminized strain rather than an autoflowering one.
Feminized seeds mean that they are designed to get rid of male chromosomes. As a result, only female plants get produced. It may seem strange, but feminized seeds can boost your yield in the end. While they can be more vulnerable to environmental stress factors, they save you work and are less prone to crop loss.
If you are growing indoors with limited space, the genetics of a feminized strain is essential for the yield. Of course, the genes can bring out other great characteristics of a plant, such as cannabinoids and flavors. A feminized strain of the sativa species is one of the best options for a grower such as yourself.
Growing Indoors or Outdoors
Outdoor and indoor environments can offer benefits in terms of yields. Growing weed outside can help make sure the plant completes its growth cycle. However, you need to time the moment you plant. Starting in the early spring can give it enough sunlight and time to go through each stage.
Plants tend to have more room and a longer duration to grow. The natural environment often leads to an increase in yields. Still, your plants are at the mercy of the weather, bugs, or animals. A great harvest needs suitable surroundings at all times. In some cases, growing marijuana indoors can improve yield size since it lowers the risk of crop destruction.
When growing inside a room, you have control over light cycles, temperature, humidity, and CO2 levels. Not to mention, you can enjoy the production of high-quality buds. You can use other yield-influencing factors to maintain a consistent yield.
Unlike the outdoors, the indoors allow people to have multiple harvests a year. However, growers can face a limited area to grow plants. Both methods can impact yield size in different ways, and it is necessary to determine which one is best for you.
The energy fuels plant growth, but the amount of light can affect how much you harvest. Too little or too much can hinder the development. Different aspects of light work together to fuel the growing cannabis. For instance, increasing the intensity can have a positive effect. You can see better yield results in the plant.
The quality of the light you use can influence your plant’s growth, metabolism, and morphology. Red and blue lighting can be the best options for improving yield as well as THC concentration. Some growers use LED lamps, and others have HPS lamps. LED lights can lead to better yields while saving energy.
If you are growing marijuana outside, the sunlight can lead to more vigorous growth. More direct sunlight means better chances of a high yield in the end. About 10 to 12 hours of sunlight a day can do the trick. Of course, a couple of more hours may have a positive effect on the harvest.
Plants should not get less than five hours of sunlight as well as less than five hours of indirect light. Make sure to choose the sunniest side for the weed garden. The light cycle plays a role in the yield size as well. A cannabis plant requires periods of uninterrupted darkness. The amount of darkness can lead to it deciding to remain in the vegetative phase or begin flowering.
Once you have a cycle of 12 hours of light and 12 of darkness, the plant will think it is time to flower. It needs enough time for this stage of development to maximize the yield.
Growing in the Open Ground or Pots
Some marijuana growers put their plants in a pot, and others grow them in the ground. Both ways can have a role in how much you can harvest at the end of the process. Growers may choose pots since the containers allow for easy portability. Pots can give you more control when it comes to the health of the plant.
You can fill the container with soil that consists of the right amount of nutrients. Not to mention, the root system is more likely to remain healthy. These factors can result in cannabis getting bigger. The size of the pot matters as well. The larger the pot, the more room the plant can grow.
However, you may want to go with planting the marijuana in the ground. You can achieve the maximum potential yield with the chosen strain. Pots can restrict how big the plant gets, but the ground offers the root system more freedom to spread out.
The open ground is restricted by the seasons, so a large yield is time-sensitive. Overall, you are more likely to attain a true cannabis giant if you choose the ground over pots.
Length of the Vegetative Stage
There are multiple stages of cannabis growth, and the second to last one is the vegetative phase. This stage can last anywhere from 3 to 16 weeks, and it is the period where the stems and leaves emerge. The plant’s growth takes off during the first couple of weeks. It matures to the point where you can see if it is male or female. The plant needs plenty of air, water, and nutrients.
What does the vegetative phase have to do with the size of your weed yield? The vegetative phase requires the most monitoring since it sets up the flowering stage. It is the most necessary stage in terms of maximizing yield. A productive vegetative stage means a large and healthy plant. A bigger plant means you can get the most out of a harvest.
Growers feed cannabis plants certain nutrients during the vegetative phase. One of the nutrients you will need to provide more of is nitrogen. Nitrogen promotes the growth of the stems and leaves, and growers take the time to prune sick leaves. It is also the phase where you would train the plant.
How big and healthy the cannabis plant gets in this phase also relies on other factors, such as indoor and outdoor cultivation.
The purpose of fertilizers is to supply the soil with more nutrients, especially if a plant lacks a specific one. Outdoor growers might add a powder version when transporting the crops outside. However, some choose not to since certain strains can easily get burned with nutrients. Too much, in general, can damage the plant.
It is necessary to wait until the vegetative stage to add fertilizer since the product will hurt any seedling. Some may wonder if fertilizers have an effect on how much you will be able to harvest after the weed finishes flowering. The products can play an essential role in correcting any nutrient deficiencies, allowing for better growth.
There are different types of fertilizers. The organic kind helps boost the aroma, but mineral fertilizers are the better option for plant size and yield. It can add more nitrogen and phosphorus, which promotes bud growth.
However, the mineral version often leaves an unwanted taste when it comes time to consume the plant. Washing out the roots a couple of weeks before the harvest can help reduce the odd flavor.
As talked about before, training is a process growers do when the plant hits the vegetative stage. Plant training involves a set of techniques to alter the marijuana plant physically for a greater yield.
There are three main types of training: bending and securing, damaging or removing, and manipulating timelines. The categories can get broken up into individual techniques. They include but are not limited to:
- Screen of Green (SCROG).SCROG is a technique where a grower places a screen over the plant. You would weave the stems through it as the crop grows. The plant will have a flat shape, which is perfect for numerous bud sites.
- Low Stress Training (LST).LST involves bending the tall stem down and away as the plant grows. It should be done early in the growth cycle while the stems are flexible. The plant will have a flat, wide shape to allow for multiple colas to sprout.
- Supercropping. Growers do a more extreme type of bending when supercropping. You might use this method if the stem is too tall and hard to tilt. Growers soften it up a bit before curving it at an angle.
- Topping.Topping involves damaging the plant when it is very young to promote various buds. You would remove the top of the seedling’s main stem. The plant will form two main stems instead and grow more than one cola.
- Fimming. There is another damage technique that is similar to topping which is called fimming. The top of the main stem gets shaved instead of removed. Fimming is less likely to stress the plant, but there is a chance it might not cause multiple cola growths.
- Defoliation. Defoliation means you would remove the largest leaves from the plant. People usually do it during the first month of flowering. The process promotes the buds to grow bigger.
Growers sometimes employ more than one technique to increase a plant’s yield.

How Much Weed Can You Grow With One Seed?
The answer to this question is very simple. How much weed can you grow with one seed? One. One seed grows only one marijuana plant. However, your motto should always be “the more the merrier”. If you only grow one marijuana seed in order to produce just one marijuana plant, you are risking the possibility that the plant could be a male one. And as we all know, only female marijuana plants produce buds and therefore are the only ones that you can harvest weed from.
Separating males from females
In order to make sure that you get at least a few females, you should choose to plant at least 5 or 6 good seeds. And to avoid pollination, what you should do is separate the males from the females in the early pre-flowering stage. You could usually already tell which ones are males and which ones are females by looking for some signs. You could also do this by putting a black bag over one part of each plant to induce early flowering. And if you see which seeds have produced buds, you would know that these are the female ones.
However, some experts advise that at first, you should keep at least one male marijuana plant together with a female one. This will result in the males transferring their pollen to the female plant and result in pollination. With only one male and female plant for this process, you are guaranteed at least a handful of seeds that you could use to plant your next batch of marijuana plants. Then when you start your new cycle, you could do the same thing with the pollination again to make sure that you won’t run out of seeds anytime soon.
Also, if you’ve got some extra seeds, you have to make sure that you store them properly so you won’t need to buy marijuana seeds again and again. The most common instruction and easiest one to follow when talking about storing marijuana seeds are that you need to store them in a cool and dry place. If you have a cool and dark cupboard where you are sure it won’t be reached by pests and bugs then it is a good place to store your seeds in. Make sure to place your seeds in an airtight container such as a Ziploc bag. You could even use a vacuum sealer to make sure that your seeds are exposed to the least amount of air and moisture as possible. And if you have access to them, you could choose to put in desiccants such as silica gel as well.
