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 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 Produce & Ways To Get Huge Harvests Each Time
Looking to get more bud for your buck? If you only have a small grow area, you’ll want to know how much weed does one plant produce. Cultivating cannabis takes effort and should be rewarded with enough smokables to warm you up through the winter.
We’ve got expert tips to get the most out of your cannabis herbage and how much reward to expect from one plant. Read on as we unpack the influencing factors and ways to manipulate them, so you get the highest yield possible.
How much weed does one plant produce: average marijuana plant yield
The average marijuana plant yield isn’t a simple figure to report. Marijuana plant yields vary depending on genetics, grow medium, and climate. Mediums like hydroponics typically give bigger harvests and more aromatic buds.
The average marijuana yield per plant generally falls into three categories: indoor, outdoor and hydro. Note these are estimates, and actual yield depends on numerous factors.
Let’s go through the three common growing styles and closest approximations of the average marijuana plant yield.
Average yield per plant indoor in soil
How much weed does one plant produce indoors? Insidelants don’t enjoy the same freedom of space as outdoors. Grow tent capacity and light wattage determines how much weed comes from one plant. You’ll typically reap anywhere from 3.5–4 oz per plant when cultivating indoors.
Lighting is of the essence in a grow tent. With proper care, you’ll get around 0.035 oz per watt of light. Using a common 600-watt lamp bumps the yield up to around 21 oz per plant.
Better light means bigger yields, so investing in a brighter lamp like 1200 watts can produce up to 42 oz of smokable buds.
Soil is a popular growing medium because it’s simple and holds nutrients well, but it doesn’t yield as high as hydroponic mediums. Using the right equipment, adequate nutrition, and efficient use of space improves the average marijuana plant yield.
Average yield per plant outdoor in soil
The great outdoors form the natural habitat of marijuana plants—free space, bountiful sunshine, and hydrating rain. Learning how to grow cannabis outdoors is crucial for all cannabis growers.
How much weed do you get per plant outside? Outdoor cultivation isn’t for everyone, but if your weather conditions are satisfactory, you can rejoice with around 17.5 oz of succulent buds per plant.
Growing cannabis on your balcony will suffice but cultivating somewhere outside with at least two meters of space is best. The biggest benefit of outdoor rearing is you can grow more plants, and they’ll have ample room, boosting the cannabis plant yield.
A pro tip for better outdoor marijuana plant yields is germinating the marijuana seeds indoors in advance because seedlings need controlled humidity levels. Germinating before spring gives plants more time to grow outside during better conditions.
Average of hydroponic yield per plant
Hydroponics is a major bud booster that entails planting in a nutrient-dense liquid. How much weed does one plant produce using hydro? Compared to soil, hydroponics boosts the yield by up to 20%, giving you 24 oz per plant using 600-watt lights.
Why does hydroponic growing change the average marijuana plant yield so drastically? It provides the optimal moisture-to-air ratio giving roots plenty of room to breathe and easily absorb essential nutrients.
Finding the proper nutrient ratio and maintaining pH levels makes hydro more complex than soil growing. Experienced growers can use hydroponics to increase how much weed comes from one plant.
What affects marijuana plant yields
How much does one weed plant produce? These six main factors play a significant role in bud bulk:
One of the essential factors determining how big, tall, or generous marijuana plants are, is genes. If it’s a low-yielding strain, no matter how much light, space, or gardening skills you use, nothing changes how much marijuana you get per plant.
Sativa strains are usually tall fast growers with slightly lower yields than their bushier counterparts. Indica strains tend to be shorter slow growers with more generous yields. Autoflowering cannabis seeds limit how much weed comes from one plant but their rapid growth cycles mean faster, more frequent annual harvests.
Level of expertise
Practice makes perfect. You’re allowed to make mistakes and use trial and error when you start your cannabis-growing journey. Seasoned growers know their way around lighting, nutrients, techniques, and increasing how much weed they get per plant.
It takes time to learn how to deal with unexpected problems like nutrient deficiencies or mold but don’t despair. You can learn how to make buds bigger during flowering, and after a few tries, you’ll be rolling in potent nugs.
Both outdoor and indoor growing produces high marijuana plant yields if you use the best techniques for the environment. There are pros and cons to each setting.
Growing outdoors is a popular choice, especially for first-time growers. Here are some pros and cons of outside cultivation:
- Larger space to grow more plants
- Natural light (sunshine)
- Easy growing
- Depends on seasons
- Unexpected weather conditions
- Higher chance of pests and mold
Indoor growing is becoming increasingly popular, especially among experienced growers. Here are some of the pros and cons of indoor growing:
- Easily hidden from neighbors
- Control lighting to increase the average yield per plant indoors, even with soil
- Odor filtration is easier (perfect for dank strains)
- No surprise weather conditions since you’re in charge
- Setup can be complex for beginners
- Equipment is costly
- Knowledge of techniques like low stress training (LST) is crucial.
The two most common mediums are soil and hydro. Both options have unique benefits helping you nurture greenery according to your experience level and budget. If you want to know how much weed does one plant produce, you must consider the medium.
Soil cultivation is the oldest and most natural method. Most plants are grown in soil as it’s affordable, easy, and gives substantial marijuana plant yields. It’s ideal for beginners because it doesn’t require complex knowledge like hydroponics.
Want aromatic, tasty buds? Soil won’t just give you a high average pot plant yield; you’ll get flavorful buds too. Your plants will be more prone to mold, pests, and diseases, but you can easily prevent them with the right nutrition and care.
How much weed does one plant produce with hydroponic growing? A bounty of buds is coming your way if you put up with the high commitment of this medium. It nourishes your plants like nothing else, creating extremely potent nugs.
Hydroponic cultivation may provide a high marijuana plant yield, but it can confuse beginners. Installing and maintaining the setup takes time, knowledge, and a bigger budget. Once you get the hang of it, the insanely juicy buds from hydroponic growing are worth the effort.
Getting a marijuana plant yield that’s not just high in numbers but has exceptional quality comes down to nutrition. Why is this so important?
Nutrients and micronutrients provide energy so your plants can bloom, protect themselves from diseases and produce bigger harvests. Marijuana plants go through different stages and require more or less certain nutes. For example, more potassium and phosphorus help them in the flowering stage, giving you a healthy cannabis plant yield.
Maintaining a pH level between 5.5 and 6.5 is just as important as feeding your herbage the correct nutrients. A balanced pH helps the roots to absorb vitamins without overfeeding. Avoid chemical fertilizers and stick with organic nutrients to make pH balancing easy.
The amount of light determines how much weed comes from one plant. Light helps marijuana plants grow, and flower but too much or too little stops the flora from flourishing. If you live in a Mediterranean climate or somewhere with at least 10–12 hours of direct sunlight, your plants will thrive outside.
With outdoor growing, your hands are tied when it comes to lighting because the only source is the sun. Indoor growers have more control and can maximize how much weed they get per plant by increasing light intensity and times. Here are some tips for indoor growers to get the most out of their lighting:
- Place bulbs close together to increase intensity.
- Rearrange plants or use the Sea of Green technique to ensure taller plants get equal access to light.
- Follow a weed light schedule to meet your plants’ lighting needs at various stages.
- Prune bushy foliage, so branches aren’t covered from the light.
- Use a lux meter to measure brightness and adjust light in areas that aren’t getting enough.
Finding the ideal wattage is essential because optimal light levels give you healthy plants with high-quality marijuana plant yields of aromatic buds. Here’s a simple guide to finding the best wattage considering the number of plants you have and the space you’re working with:
|Grow area (m²)||Number of plants||Recommended wattage|
How to estimate the yields of your weed plants
There are many ways to determine how much weed comes from one plant, but most growers consider lighting indoors and pot size when growing outside. Note that once buds are dried, they become much lighter. To estimate how much you’ll end up with after curing, multiply the weight of fresh buds by 0.25.
How to calculate indoor yield estimates
If you know how to grow cannabis indoors, you’ll know lighting is the most important step to master because it determines marijuana plant yields. You can calculate the average yields by the intensity of your lights.
Of course, other factors like growing experience influence the possible harvest. Experienced growers typically get double the yield beginners get. Space, nutrients, and strain type influence the average yield per plant indoor in soil or hydroponic setups.
Here’s a general guide to estimate your indoor yield according to HPS lighting:
|Lighting wattage||Growing space||Approximate yield|
|250 W||1x 0.5 x 2 m||3–9 oz|
|400 W||1 x 1 x 2.5 m||4–14 oz|
|600 W||1.3 x 1.3 x 2.5 m||5–21 oz|
|1000 W||1.5 x 1.5 x 2.5 m||9–36 oz|
How to calculate outdoor yield estimates
Calculating the average marijuana plant yield outdoors is tricky. Generally, growers use five-gallon pots and get around 3.5 oz of dry bud per plant. Some strains can give you up to 59 oz per plant outdoors, so it mainly comes down to genetics and care.
How to maximize the yields of marijuana plants?
Increasing how much weed grows on one plant involves working on all factors of marijuana cultivation. It’s challenging to predict your harvest accurately, but you can take steps to ensure you get the best buds possible.
Here are four tips to maximize your cannabis plant yield:
Getting a huge harvest of potent buds begins long before you know when to harvest cannabis. It starts with using high-quality marijuana seeds and germinating indoors for healthy seedlings. Once seedlings are ready to plant, ensure the following factors are ready:
- Training techniques
- pH levels
Grow fewer plants
Less is more, especially when it comes to optimizing the marijuana yield per plant. More greenery requires more lights, and that’s not always feasible.
Growing a few plants allows you to focus more on caring for them, and they’ll get sufficient light. You’ll get a higher marijuana plant yield with fewer plants and more light than with more plants and less light.
Use high-intensity discharge lights to get the highest possible cannabis yield per plant. Using 600-watt lamps spaced evenly gives plants equal light feed. Ensure adequate ventilation because they need enough CO2 to convert the light to energy.
Marijuana plants naturally grow upwards with one main cola and many branches that typically don’t get even amounts of light. This apical dominance hinders the growth of the bottom buds. Training plants help them grow so that each branch gets enough exposure.
The Sea of Green (SOG) method is a popular technique for indoor growers to increase how much weed they get per plant. It involves training herbage to grow horizontally using a mesh screen, so all buds grow with the same amount of light.
LST is a popular method for many outdoor growers, which requires bending the plants over time and tying them down. This technique makes plants grow laterally, so there’s even light distribution. Usually, the bottom buds are frail because they don’t get enough light, but with training techniques, you get all potent, juicy nugs.
May your harvest be bountiful
Maximizing your marijuana is obtainable with a few tweaks to your growing methods. Powerful lighting, adequate nutrition, and training techniques are crucial for increasing the overall marijuana yield per plant. With practice and dedication, your cannabis plants will reward you with huge harvests.
As important as your growing method is, you won’t get glorious yields with mediocre seeds. Check out the top-quality cannabis seeds at Homegrown Cannabis Co., and you’ll be swimming in pools of plump buds in no time.
