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 does one plant produce? This article discusses some of the variables that will impact the final harvest of your cannabis plants. The average yield over a cannabis strain depends on various factors. But how much weed does one plant produce? Check it out!
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.
How Much Weed Does One Plant Produce?
“How can I grow as much weed as possible?” You know that’s what’s on your mind when you ask or wonder about plant yield. Old and new marijuana growers (and scientists and politicians ) alike want to know how to get the highest yield per plant and per grow. Planning and practice can make a huge difference– especially when you are only growing one plant!
But, ultimately let’s not forget that the cannabis plant is a sentient being. She’s alive! Her growth is dependent on many factors and the same plant can produce a pound in one situation and a couple grams in another. Below we will detail the known factors that impact yield and potency, discuss where things can go wrong, and where things can grow right.
What is yield? (wet vs. dry yield)
Yield is the amount of weed you get when you harvest your marijuana plants. This is only the buds themselves, removed from the stems. This is most often measured once your marijuana buds are dried and trimmed. This is generally measured in grams, ounces, and pounds. The “lid” is not a used measurement anymore.
One of the most know measurements currently is an 1/8th (of an ounce) which is 3.5 grams. This is commonly found in dispensaries as well as something one might purchase from their friendly neighborhood weed guy. In this picture below, only two perfectly grown and cured buds were needed to reach this weight!
Wet and dry cannabis does not weigh the same.
Immediately upon harvesting, your buds will be quite heavy. That’s because, like humans, freshly harvested cannabis flowers are 75 – 80% water by weight. Once dried and cured, the actual harvest you get is about ¼ of the wet weight. So, if your harvest weighs out at an ounce at first cut, when it’s all said and done, you will have a quarter ounce of homegrown weed to smoke.
To estimate your dry yield from your wet yield, just multiply the wet yield by 0.25 to get an idea of what you’ll have to share with your friends (or stash away for yourself)!
This varies slightly depending on if you grew a sativa-dominant or an indica-dominant strain. Sativas are notoriously more airy so if you weigh your sativa harvest wet, you will get 20 – 22% dry. Indicas tend to be a bit chunkier so if you weigh your indica harvest wet, you will get 22 – 25% dry.
Yield vs. Potency
Yield is an important factor to consider because cannabis is an annual crop; there’s only one harvest per plant. After harvest, the plant is dead and returns to compost. Yield is the weight of the buds that you harvest. Yield should not be confused with the potency of these hefty green nuggets. Potency is the strength of the cannabinoids found in the trichomes on your cannabis buds.
In other words, you can have a high yield of low potency buds. Or you can have a low yield of high potency buds. In a perfect world, you’d get a high yield of high potency buds and we are going to discuss how to make that happen!
What to do to increase your weed plant’s yield?
Let’s get the most out of your homegrown medical (and recreational) marijuana. Best plant performance and yield are the result of growing the right strains under the right conditions. The most important factors being: light, plant density, fertilizer, temperature, duration of the flowering growth stage, and plant variety. In sum, the TLDR version is:
blast as much light as you can afford, grow less plants to fill your space appropriately, feed your plants just enough but not too much, keep the space not too hot and not too cold, don’t harvest early, and don’t buy shit genetics
(bag seed gamblers are included!)
Light to Increase Weed Plant High Yield
The yield from an indoor-grown cannabis plant largely depends on the light the plant receives. Cannabis plants, being photosynthesizers, receive all their energy to function from light.
The type, quality, and amount of light you provide your marijuana plant directly influences yield and should not be taken lightly (see what we did there?)
Sunlight is the most powerful light us earthlings have access to, so if you are able to give your plant direct sunlight, do it! Sunshine is also free, and that is a big plus. The only downside is that we cannot control cloudy or rainy days and winter makes it challenging to grow with the limited amount of sunlight (the freezing temperatures also don’t help).
Moving to an indoor grow environment, w hen it comes to lighting fixtures, it does not benefit you to get the cheaper option. And we know how challenging it is to pick the right light- – there’s so many options out there! (incandescent, CFL, HPS, LEDs)
We do not encourage growers to use incandescent light bulbs when growing indoors. To get enough energy for your plant, the bulb would put off too much heat and not be fun to see on your electric bill. CFL bulbs are equally useless. Stick to new technology to protect your plants and your wallet.
While HPS light fixtures are historically the choice for those who want to maximize their indoor cannabis crop harvest, they are slowly fading out from commonplace. An experienced grower can expect to harvest a gram of weed from each watt of HPS light provided to the plant. This means that if the light is a 400-watt HPS bulb, then 400 grams of weed could potentially be harvested. However, LED light technology is getting more advanced. LEDs are: 1) cheaper to run than HPS and 2) run cooler than HPS which also lowers the cost of air conditioning and 3) reduces the likelihood of burning your plants with too much light.
When choosing an LED light fixture for your weed plants you are up against a surplus of options and information.
The most important metrics to look for in a lighting fixture are PPF, PPFD, and energy usage/efficacy . If none of these are present, you may want to look at a different fixture.
PPF, PPFD, and photon efficiency are measurements related to PAR. PAR is photosynthetic active radiation. PAR is not a unit of measurement but instead defines the type of light needed to support photosynthesis.
PPF is how much PAR a lighting system produces each second. This is not often listed as it does not show how much of the measured light actually lands on your plants but is a useful metric to calculate how capable a light fixture is at creating PAR.
PPFD (photosynthetic photon flux density) is the measurement of how much PAR actually arrives at your plant. This is a spot measurement and is typically highest at the center point beneath the light and decreases as light ripples outwardly. This changes with the distance away from the plant. Ideally, the higher the better but a single measurement won’t tell you much– you want the average taken from many measurements throughout the coverage area.
Photon efficacy is a way of defining how good a lighting fixture is at converting the electrical energy into PAR light that your plant can actually consume. This is not often listed in the spec sheet for most lights. Instead, most light manufacturers list the wattage, either total electrical watts or watts per square foot. Knowing the wattage is good to budget the main cost of your indoor cannabis grow. But the wattage doesn’t give the best information about the quality of light as watts are a measurement of the energy coming into the light fixture (from your electric bill) where photon efficacy is how good the light is at giving your plant energy.
We suggest paying attention to whether or not the company you want to buy a light from lists the actual wattage or the watt equivalent. (Hint: if they are only disclosing the watt equivalent, the light is most likely not strong enough for cannabis.)
LED wattage and incandescent wattage aren’t the same.
Many LEDs are marketed with their “incandescent equivalent” wattage, referring to the brightness of the LED. For example, a 10 watt LED may say “75 watts” on the package and in fine print say that the brightness is equivalent to a 75 watt incandescent. But for growing cannabis, you’re going to want an actual real 75 watts (or higher!) from your LED lamp .
Can I give my weed plant too much light?
The answer in fancy, science talk:
Effectively, within the range of practical indoor PPFD levels—the more light that is provided, the proportionally higher the increase in yield will be. Therefore, the question of the optimum LI [light intensity] may be reduced to more practical functions of economics and infrastructure limitations: basically, how much lighting capacity can a grower afford to install and run? – Victoria Rodriguez-Morrison, David Llewellyn , and Youbin Zheng
In plain English:
No, not really! For a vegging photoperiod cannabis plant, you will want to give her a minimum of 18 hours of light a day– some give 20 hours or even keep the lights on 24/7. We know that a lot of good growth happens during the dark period when the cannabis plant has time to rest so we suggest either a 18/6 or 20/4 light cycle for photoperiod cannabis in the vegetative stage.
Same goes with autoflowering cannabis, with an autoflower seed indoors, you’ll want to give it 20 hours light / 4 hours darkness each day.
When it comes to using light to maximize yield, maximize the light intensity to meet your budget.
Grow Less Cannabis Plants to Get More Weed
In some ways you may think that if you pop more marijuana seeds or get more clones that you will get a bigger harvest in the end. This is not always true.
Each cannabis plant wants her own space. Planting more than one seed in a pot leads to competition between plants for the shared nutrients and reduced yields. As seen in this photo below where two seedlings starved each other and both ended up dwarfed:
The size of the container that you grow your pot in matters, too. Outdoor plants have the potential of reaching extreme oak tree size when planted directly in good soil (which can be hard to find) and allowed to flourish in an open, sunny space. Indoor cannabis plants, become much like a goldfish in either a fishbowl or an aquarium or an ocean, you will grow a different size plant from the Mini Complete Pot Grow Kit (1/2 Gallon) to the Medium Complete Pot Grow Kit (5 gallon) or the Large Complete Pot Grow Kit (35 gallon) . The bigger pot, the bigger plant (and the more pot).
Growing in a grow tent, consider the total space as well as the size of your containers. It may sound like a good idea to pack a small 24’’ x 48’’ x 60’’ tent with as many pots as possible but this will limit the canopy space for your plants to fill. Best to give each pot space for the plant to fill out.
Growing less plants means:
- A longer vegetative stage. This means bigger plants. Bigger plants have bigger harvests and higher yield. When growing photoperiod cannabis indoors, it is time to transition your tent to flower when the tips of the leaves of each plant begin to touch. More plants touch each other faster.
- Less plants to manage! You know each one personally and can tell when even the slightest thing is off which means you can catch pests and diseases before they become a major problem. This also means that you will have more time for defoliation and advanced pruning techniques to maximize your yield!
In the same space with a 600 watt HPS lamp, you can either get 37.5 grams from 16 plants, 150 grams from four plants, or a pound from one single plant! Don’t compromise on plant density; the more space you give a single plant, the more she can blossom.
Best Grow Mediums to Maximize Harvest
Yield can also vary based on the particular grow medium you use. It has been clearly documented that using hydroponics to grow marijuana can result in 20 percent more yield compared to using soil indoors.
Hydroponics increases yield because it is the most efficient way to feed plants. The grower supplies all the nutrients that the plant would naturally need to find for herself in the soil.
But, hydroponic systems are also 1) more expensive to set up and run, 2) can take time (like several runs) to dial in a nutrient feeding schedule and 3) can go wrong if your plants are fed too much.
At the simplest level, fertilizers come in varying NPK (Nitrogen, Phosphorous, and Potassium) formulations. Fertilizers that are richer in nitrogen are ideal for the vegetative phase, and those richer in potassium are better suited to the flowering phase. Growing hydroponically you need to know which nutrients your cannabis plants need during their different stages of growth and have that ready.
Whether you opt for organic, inorganic, or a mixture of the two is more of a personal decision. The important thing is that your marijuana plants receive enough nutrients to give you a higher yield per plant, but never too much. Unlike light intensity, there is a sweet spot for nutrients when it comes to growing marijuana. Too much of a good thing can negatively impact your plants. Unfortunately, finding the right balance between enough nutrients and excess nutrition usually comes with experience.
Soil grown marijuana can pull down some epic yields as well. But not all soils are created equal. For example, one person growing marijuana in loam soil may have a richer harvest since loam soil is easy for the roots to penetrate. On the other hand, clay soil could lead to a dismal yield since it doesn’t easily drain and can be quite compact, making it difficult for cannabis roots to grow.
That’s why a Pot for Pot specially formulated our Superb Soil to contain just the right amount of nutrients to maximize cannabis growth. With a Pot for Pot grow kits, there’s no need to add additional fertilizer because their soil has everything your plant needs from seed to harvest . It isn’t just easy to use, it’s optimized for marijuana growth.
Our complete grow kits include everything you need to go from seed to your very own supply of high grade medical cannabis.
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.
