How Much Does a Weed Plant Produce?
Cannabis growers typically find themselves boasting about their latest colossal harvest, and for experienced growers, this may be true. For many beginners, getting a pound or more of marijuana yield per plant may be challenging.
Even though healthy cannabis plants tend to produce more marijuana, to get this kind of cannabis yield, the grower needs to control several variables.
There are no set rules for getting the most out of each harvest, making it near impossible to determine exactly how much weed you can get from one plant.
Growers need to have a thorough understanding of the things that determine marijuana yield. Let’s take a closer look at how much weed from one plant you can expect and the various factors that may affect the outcome.
How Much Weed Does a Plant Produce When Grown Indoors?
Growing conditions play a significant role in determining how much weed you can get from one plant. Whether you’re growing weed indoors or in a greenhouse, there are typically limits to the height and diameter allowance of your greenery, which may affect your marijuana yield per plant.
Indoor growers have increased control over their plant’s environment, and grow lights play a critical role in this process.
Under perfect conditions, experienced growers can expect to harvest as much as 1 gram (0.035 oz) of weed per watt of light per plant. For instance, with a 500-watt HPS grow light, you can potentially yield 500 grams (17.5 oz) of usable, dried marijuana per plant.
It’s critical to simulate the growth’s perfect outdoor environment while simultaneously minimizing its challenges and risks to create a thriving indoor garden.
In a controlled environment, it’s essential to provide enough room for each plant to grow with minimal humidity, temperature, and flight disruptions.
Successful indoor growth is a complex and costly process that involves constant care and meticulous planning. Do it correctly, and you’ll get rewarded with beautiful, high-yielding marijuana plants.
How Much Weed Does a Plant Produce When Grown Outdoors?
Outdoor cannabis growing tips are widely available on the net and usually exceptionally helpful to increase your marijuana yields. That said, it becomes significantly more challenging to control the environment in which your plants grow if you’re raising them outside.
Under ideal conditions, you can expect your marijuana plant yields to be in the region of 500 grams (17.5 oz) per plant.
For outdoor growth, it’s best to germinate the seeds early and indoors where you can fully control the temperature and humidity. It also helps to allow the plants enough time to grow reasonably large before moving them outside.
When growing outdoors, it’s crucial to give each plant enough space to develop(at least one to one-and-a-half meters between them ) to maximize marijuana plant yield. If you prefer to use containers, they should be not less than 50 liters (15 gallons) in size.
It’s also critical to ensure that your garden gets enough water and has ample nutrients to sustain proper growth.
Factors That Impact Marijuana Plant Yields
Many variables may affect your cannabis plant yield, and it’s crucial to have a comprehensive understanding of these factors to maximize your harvest.
Size of Grow Space
Grow space size varies significantly between indoor and outdoor crops and your choice of cannabis strain.
For indoor growth, you’ll require between one and three square feet per plant, depending on the size of the pots, ventilation, and your lighting setup. Your plants will need six inches to a foot of space between them to experience maximum growth.
You’ll be looking at anything from a one to a five-gallon-sized pot, depending on the cannabis strain you intend to grow.
For outdoor growth, it’s essential to keep a distance of at least one to one-and-a-half meters between plants, although more is better.
If you prefer to originate your weed in containers, you’ll require a 15-gallon or larger pot to ensure there’s enough space for the roots to develop properly.
The plant’s genetics greatly determines the cannabis yield of your growth due to some strains getting cultivated to maximize bud production. For instance:
- While Indica strains are less potent than different types of weed, they produce more buds
- Sativa strains are considerably taller and produce fewer buds than other marijuana types but contain higher levels of THC
It’s also essential to keep in mind:
- As opposed to using clones, growing your plants from seed will usually result in a higher marijuana yield.
- Autoflower strains get cultivated to flower after a set number of weeks, resulting in smaller overall marijuana yields. It’s significantly easier to work these plants into a rotating schedule, though, increasing the total amount of cannabis harvested annually.
Light Type and Amount
When you’re growing marijuana indoors, perfecting the lighting is the most crucial factor.
Marijuana strains generally need fixed daily hours of light through every stage of the growth process.
Without this set schedule, most plants will initiate the flowering stage prematurely, minimizing your harvest. It’s essential to familiarize yourself with the specific type’s requirements before working out the illumination timetable.
The amount of light is also critical. Growers can expect to produce an average of one gram of dried weed per watt. If you’ve got an insufficient amount of bulbs, you could minimize your yield per plant.
It’s vital to ensure that you’ve got enough light-bulbs to sustain your entire garden effectively.
Regardless of your garden’s size or location, training your marijuana crop will significantly increase your growth’s quality and quantity by altering the plants’ chemical balances. There are various techniques available, split up into two categories:
- Low-stress training (LST): Doesn’t involve inflicting damage directly to the plant
- High-stress training (HST): Involves removing or breaking parts or sections of the plant
The most widely used LST techniques are:
- Low-stress training (LST)
- Screen of Green (SCROG)
Noteworthy HST techniques include:
- F**k I missed (FIM)
- Stem mutilation
“How much weed does a plant produce?” Before you can answer this question, you should consider the best type of medium to grow your marijuana.
The chosen medium can have a considerable effect on the final results. Although there are numerous growth options available, each impacts the overall cannabis yield per plant differently due to a variance in the source’s actual growing conditions.
While soil is the most commonly used medium to grow cannabis, it’s essential to use the correct type of dirt. For instance, loam allows for effortless root penetration and will produce a more fruitful harvest than clay or turf.
On the other hand, using hydroponics with media such as coco coir or perlite can potentially result in a 20% higher yield compared to growing your plants in soil indoors. This type of medium grants you significantly more control over their nutrient intake.
High Yield Strains
Selecting strains with a high yield potential will significantly impact the quantity and quality of your harvest. To get you started, here are some extreme yielders available through i49.
Critical Mass Feminized
As an indica-dominant hybrid, feminized Critical Mass seeds contain the illustrious Skunk #1 and Afghani strains’ superior genetics.
Users will benefit from the calming effect of this profoundly relaxing cultivar, leaving them feeling happy while soothing away bodily discomforts. In turn, these effects can alleviate the symptoms of a broad range of health conditions.
Blue Dream Feminized
As a hybrid, feminized Blue Dream seeds come from two legendary strains: the indica Blueberry and the Sativa Haze. The lingering sweet and delicious flavor of this weed makes it a delightful dose of metaphorical and literal medicine.
Typically dominant on the Sativa side, users will find themselves on an energized high that sinks into an alert but toned-downed, mellow trip, making it the ideal choice for day-time smokers.
Gorilla Glue #4 Feminized
As its name would suggest, Gorilla Glue #4 packs a heavy punch. This balanced hybrid contains monumentally high THC levels. When smoked, CG4 will hit you with a waft of a deep pine fragrance and leave you with a lingering sweet berry scent.
Highly-prized for its capacity to relieve pain and stress and induce sleep, users will find themselves on a cerebral high, leaving them completely relaxed and gorilla-glued to the davenport.
Ways to Boost Yields Per Plant
Managing how much weed one marijuana plant yields is merely a matter of using the correct strains and providing them with an excellent growing environment. Assuming you tend to avoid making major mistakes, you can easily reap the same rewards an experienced grower will get, even on your first attempt.
Here are some essential growing tips to help you maximize your yield.
Grow in Hydroponics
Growing weed hydroponically gives you considerably more control over your plants. While this method typically produces a higher yield on average, it’s significantly more challenging to manage than raising traditional soil-grown cannabis.
Using the right genetics, experienced producers can effectively harvest up to 1.2 grams of weed per watt of light.
Use the SCROG Method
The SCROG technique is a unique growth method through which you can increase your yield. It involves topping your plants and covering them with a screen roughly 15 inches above your greenery.
When a branch reaches a height of 4 inches above the filter, you need to tie it to the screen. Continue this process until you end up with a blanket of tops.
By using this technique, you’ll not only avoid wasting light but also ensure all of your plants grow to be the same height and that they won’t produce any soft or fluffy buds.
Choose the Best Lights
Marijuana plants require plenty of lighting, and choosing the best bulbs is critical to maximizing your yield. For instance, a decent LED growth light will provide you with a significantly higher wattage output than a weaker lamp.
It’s crucial to ensure that you provide nothing less than 100 umol/㎡/s to the corners of your grow room, with a much higher intensity in the middle. To figure out exactly how much light you’ll require, you need to consider the growth area’s size and the number of plants you’re planning on raising.
How to Calculate Marijuana Plant Yields up Front
Determining how much weed you’ll yield per plant is challenging due to the number of variables involved. It’s not an exact science, and there are some methods you can use to at least get a ballpark figure.
Using Pot Size to Estimate Yield
The growth of marijuana plants gets severely limited by their pot capacity. Although size isn’t a perfect yield indicator, it can give a rough idea of what to expect.
Assuming that you’re growing in 18-liter pots, using high-yielding seeds, some light training, and proper nutrients, your plants should reach a height of at least 90 cm.
With solid lighting and four to five weeks of vegetative growth, these crops should produce at least 100 grams of dried weed per plant.
Using Lighting to Estimate Yield
Using lamp strength to estimate your yield isn’t an exact science; it’s considerably more accurate than calculating your potential harvest based on the number of plants you’ve got.
Experienced growers raising their plants indoors can expect a yield of roughly one gram of dried weed per watt of light.
First-time growers can expect to harvest about 0.5 grams per watt.
Boost Marijuana Yield Per Plant and Save Money
Growing your own cannabis can save you a significant sum of money, especially if you do it cheaply and efficiently. Here are some tips to help you boost your marijuana yield while cutting down on costs.
- Invest in low-cost, high-quality seeds
- Save money by cloning your plants
- Don’t throw away the trim; use it to make salves and ointments
- Repurpose every-day waste, making it useful in your greenhouse. For example, turn food cut-offs and left-overs into compost
- If you’re in a non-friendly cannabis environment, use autoflowering seeds to grow your weed
- Invest in decent soil modified for cannabis growth
- Save money and time by planting your marijuana in a bale of hay
- Keep to the essentials and don’t invest in unnecessary equipment
- Consider growing your cannabis in soil
- Avoid going overboard on supplements and nutrients
- Use training techniques to maximize your yield
To Wrap Up
With so many factors affecting the outcome of your growth, it’s exceptionally challenging to predict how much weed you will get from one plant.
On the positive side, there are various proven methods growers can implement to boost their cannabis yield, saving them a significant amount of money at the end of the day.

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 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.
