How much weed does one plant yield

The average yield over a cannabis strain depends on various factors. But how much weed does one plant produce? Check it out! Last updated 06/12/2022

    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
    2. Masure yield by cubic feet

    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:

    Genetic Quality

    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.
