How Much Weed Can You Really Produce Per Plant?

Wondering how much weed you can produce per cannabis plant? Here’s everything you need to know about the variables affecting your yield.

Cannabis growers love to boast about huge harvests, but just how much weed can inexperienced growers expect to harvest from a single plant? In this article, we’ll take a closer look at cannabis yield and what influences it, and much more.

If there’s one thing that’s certain about growing cannabis, it’s this: results vary. A lot. There are many different variables that affect your plants, their health, growth, and the amount of flower they produce. And frankly, trying to guess the size of your yield before harvest is really difficult.

Most rookie growers estimate their yield based on the height of their plants. And that makes sense—at least in theory. Unfortunately, plant size isn’t a very accurate indicator of final yield. In fact, it’s really hard to estimate the size of your yield just by looking at a single aspect of your plant (like height, for example).

Cannabis buds develop on what growers refer to as “bud sites”. These are the spots on branches where pre-flower structures form roughly 4–6 weeks into a plant’s life cycle. Once a plant enters its flowering phase, it stops dedicating its energy to developing foliage, instead focusing on producing healthy buds on these sites. How big and dense these buds become depends on a lot of different variables, including light, nutrients, genetics, substrate, and more. The size of a plant, on the other hand, says little about how many bud sites it will develop, or how big/dense its buds will be come harvest.


Light is arguably one of the most important factors affecting your yield. To maximise output, you should maximise light exposure to your plant early on by using training techniques to manipulate growth. One popular training technique is low stress training (LST), which involves bending and tying down branches to optimise light exposure and encourage a more horizontal structure. The screen of green (ScrOG) method takes this further, situating a mesh screen over plants, upon which new growth is woven in an effort to boost final yield. There are many more techniques where these came from, including high-stress tek like topping (in which the main growing tip is cut off) and defoliation, to name just a couple.

Nutrients are also really important, and you’ll want to make sure your plants always have access to the macronutrients and micronutrients they need at each stage of growth. When it comes to nutes, your plants require different ratios depending on their phase. During veg, plants require higher levels of nitrogen, whereas flowering plants require more potassium, phosphorus, and micronutrients like calcium and magnesium. In addition to the nutrients themselves, plants need to be able to uptake these nutrients to develop huge hauls of big buds. In order to do so, the pH level has to be dialled in for the type of grow you’re conducting.


Arguably the most crucial factor that determines final yield are genetics. And just like there are some strains that taste better than others, there are also those that produce better harvests than others.

Remember that cannabis strains have been bred to meet the demands of growers and consumers. And with yield being so important, there are countless strains out there that have been purposefully bred to produce numerous bud sites and develop bigger, heavier flowers. Make sure to check out some of our XL strains if you’re looking to really rake in the buds.


There are many different grow media out there, and they all have different effects on the overall yield of your plants.

While soil is easily the most common medium used to grow cannabis, hydroponic media like perlite or coco coir give growers a lot more control over the nutrient intake of their plants. And while that kind of control may be overwhelming for rookie growers, experienced growers can use it to really push their plants to the next level and produce massive yields.


Whether you grow indoors or outdoors will have a big impact on your plants.

Indoor growers generally have less space to work with, which means they’ll usually grow fewer, smaller plants than someone growing outdoors. However, indoor growers also have much more control over their plants’ environment. Hence, they can play around with things like lighting, temperature, and humidity to fine-tune their growing conditions and optimise yield.

Outdoor growers, on the other hand, usually have much more space to work with than indoor growers, meaning they’ll be able to grow more plants in a single season than indoor growers. Plus, outdoor growers also have the benefit of growing under the best possible light source in the world—the sun. However, outdoor growers don’t have the same level of control over their environment, meaning their yield is subject to the season, which, depending on where you live, may be unpredictable.


This is another important factor that affects your overall yield. The more fine-tuned your skills, the more control you have over your plants. And the more control you have over your plants, the better your yield.


While yields vary a lot, there are some ways you can get at least a rough estimate of how much weed you’ll produce.


Remember that cannabis plants will only grow as large as their pots allow them to. And while size is, as we saw earlier, far from the perfect indicator of how much you’ll harvest, it can help you get a ballpark estimate of what your harvests will look like.

Ideally, you’ll want to grow in at least 18-litre pots. With this amount of soil, some decent nutrients, and some light pruning/training, you should be able to grow large, healthy plants that reach at least 90cm in height. Given they get a full 4–5 weeks of vegetative growth and solid lighting that penetrates right through to the lowest bud sites, plants of this size should be able to produce at least 100g of dry bud per plant.


Some growers choose to estimate their yield based on the strength of their lamps. And while this is far from an exact science, it can be a bit more accurate than calculating your yield per plant, especially if you choose to grow multiple smaller plants, rather than just a few larger ones.

If you’re growing indoors and have at least a few harvests under your belt, you can expect to harvest roughly one gram for every watt of light. If you’re a newbie grower with little-to-no experience, expect yields of around 0.5g per watt.


Growing hydroponically gives you a lot more control over how your plants feed. With the right equipment and experience, this can greatly improve the size and quality of your yield. Experienced hydro growers, for example, can encourage yields of up to 1.2g per watt of lighting. By this logic—and using a 600W lamp—a good hydro grower can harvest over 700 grams of bud (genetics depending)!


Remember, the weight of your buds will drop dramatically after drying and curing. So don’t get too excited when you weigh your buds right after trimming. Instead, multiply your wet yield by 0.25 to get a rough estimate of how much dry bud you’ll end up with.


Growing cannabis can be challenging, but there are plenty of things you can do to improve your yield as a novice grower. These include:

• Start with the right genetics. Professionally bred strains will always produce better yields than bagseed.

• Read up on training techniques. Training your plants to grow a certain way maximises their exposure to light, which will ultimately improve your yield.

• Know your nutrients. Use the info on our blog to learn more about how to use nutrients to really maximise your plants’ potential.

• Experiment. Don’t be scared to try new grow techniques and push yourself as a grower.

• Go hydro! Once you’ve got a few harvests under your belt, consider immersing yourself in the world of hydroponics, where you’ll have even more control over your plants and their growth.

• Keep growing! The more experience you have, the better you’ll get. Hence, make sure you grow consistently to hone your skills and become evermore in tune with cannabis.

One of the things that’s on the mind of almost every grower is how to increase marijuana plant yield; we all dream of growing monster plants with monster yields, but what can you do to actively increase yield when growing?

Many growers look to increase yield in order to tide them over to next year’s harvest, or maybe they also supply family members with medicine. Regardless of your reasons, this post is designed to help you learn how to increase your cannabis plant yield by simply changing a few key aspects of the process.

In this article we’ll take you through some techniques used by experienced growers that have been tested rigorously our team here at in order to guarantee the best possible results.

Best Grow Setup for Yield – Tips and Tricks

This guide is a general guide on how you can increase yield in your original, existing set up – obviously a larger growing surface means larger yields, but we’re going to be giving some additional methods. For example, Indica strains, due to structural differences, tend to produce larger yields than sativa strains. They tend to grow shorter than sativas while producing more branches, which therefore produce more flowers and larger yields.

Another couple of things to keep in mind are watering and feeding; feeding your plants in excess or watering them too much is a big mistake. It may seem like the more you give your plants, the more they grow, but in this particular case less is always more; it’s much harder to fix over-feeding or over-watering than to increase the amount of water or nutrients.

Generally, there are three major factors to keep in mind: the nature of the plant in question (in this case, the genetics of the strain you wish to grow), nutrient schedule (watering and fertilizing) and last but not least, climate issues (temperature, humidity and light).

How Genetics can Determine Marijuana Plant Yield

One of the most important things to keep in mind when trying to improve yield rates is to focus on strains that have a genetic predisposition to grow and develop larger flowers. All types of seeds have their own pros and cons; hybrids are generally much more resistant to typical cannabis grow issues such as insects and rot, whereas regular landrace strains tend to produce higher quality flowers.

Some strains known for producing large yields are Big Bud (Sensi Seeds), Critical+ or Industrial Plant (Dinafem), Monster (Eva Seeds), Critical Kush and Vanilla Kush (Barney’s Farm), King Kong (Dr. Underground), White Rhino (Green House) or Blue Rhino or Somango 47 (Positronics) and many others.

Nutrients’ influence on cannabis yield:

Being honest, given normal growing conditions, cannabis plants can survive on quite a little. There are quite a few places where cannabis plants grow in the wild, without any type of help. That aside, fertilizing and proper watering can mark the difference between “wild weed” and a robust plant capable of producing decently large yields.

Good substrate and decent fertilizers used correctly during each stage, as well as high quality water, already guarantees a massive increase in yield when compared to plants grown in the wild.

How often you water the plant will generally depend on what kind of substrate you’re using. Once it’s dry or almost completely dry, you should proceed to water. Try to avoid watering before it’s dried up, or you can accidentally cause excess humidity which can lead to root rot, killing off your plant entirely.

When it comes to fertilizer, you can use root fertilizer, growth fertilizer, flowering, fattening, enzymes, sugars… The most standard fertilizer is usually going to be a root stimulant, alongside normal growth and bloom base fertilizers. We recommend using the same brand of products for your plants if possible, such as Boom Nutrients. This can greatly increase your chances of producing a larger marijuana plant yield.

When fertilizing it’s important to keep in mind that there are two main types of fertilizers: mineral fertilizers and organic fertilizers. While organic fertilizers are better for increasing aroma and flavor, mineral nutrients are more effective at increasing size and yield. When using mineral products, always make sure to wash out your plants’ roots two weeks before harvesting in order to avoid unwanted tastes or effects when consumed.

Climate and marijuana plant yield

In this section we’re going to look at both indoor and outdoor growing, where climates can vary.

Generally, you’re going to get much better results from indoor plants. The reasoning is pretty simple; you can easily have absolute control over the climate that your plants live in. However, outdoor grows are essentially at the whims of nature; you can protect them and give them the best chance, but you can’t rule out a really bad day either slowing down or ruining your plants. Outdoor grows are usually during the driest, hottest months if you have the climate for it.

Indoors, you can easily know the temperature and humidity in your grow room at all times using a thermos-hygrometer device, adjusting the parameters if your plants need it. If it’s too hot because of the type of grow light being used, or the season of the year you’re growing in, you can use an extractor or a cooling kit.

Humidity is ealso super easy to keep under control when growing indoors; you can use an automatic humidity controller that increases and decreases the humidity in your grow room as needed – you won’t have to do a thing. You can also have a normal hygrometer and adjust humidity by spraying water etc.

In as far as lighting, we all know that photosynthesis is one of the most important elements regarding the growth and development of any sort of plant, including cannabis. When it comes to grow lights designed specifically for cannabis, more photons (lumens) generally means much better development, although make sure to thoroughly investigate the lights you plan on using; some bulbs are designed for the vegetation period and others are designed for the flowering period.

These three factors can change depending on whether you’re growing outdoors or indoors, and they can also change depending on how you’re growing your plant; whether it’s in a pot with peat, coconut or fiber, aeroponic, hydroponic etc. When it comes to autoflowering plants, most of this advice isn’t that helpful; autoflowering plants grow so fast that all you need to know is make sure not to over-water and to give them a decent nutrient schedule from the get-go.

That being said, we’re going to try and make a list of some of the most used tips when it comes to getting your plants to produce larger and denser flowers.

  • When it comes to feminized plants, do not plant them directly in their definitive flowerpot. Instead, you need to do various transplants (usually one or two, you’ll have to transplant it again before it begins to flower) to bigger pots. This allows for more root growth and larger plants in general.
  • Slightly more expensive methods, such as the use of Co2 systems or ozone kits, can also help to increase yield. Regular growers don’t use tend to these systems, whereas professional growers and seed banks do.
  • Selective pruning and cutting (some growers even practice selective pruning on auto-flowering plants, although we don’t recommend it) can help the rest of the branches and buds to grow better. There are many different methods and theories regarding how to best prune or defoliate your plants. We recommend checking out our posts regarding removing leaves and pruning.
  • Wiring or stringing the plants, whether they’re feminized or auto-flowering, helps them to create a much sturdier structure and increases the number of flowers on your plant while also making the buds fatter.
  • Grow methods such as SCROG (Screen of Green) and SOG (Sea of Green) can increase yield when growing one or two plants.
  • It’s incredibly important to not stress your plant out during the flowering cycle; don’t prune, don’t transplant it or do anything else that could possibly stress it out.

How to Increase Cannabis Yield

Quantity isn’t always the same as quantity; sometimes, to harvest a larger marijuana plant yield you may need to grow a specific strain rather than others you may prefer the aroma or effect of. Most of the ways to increase aroma, flavor or effect are usually counterproductive to increasing yield size when it comes to using nutrients; organic nutrients are much better for aromas and flavors, whereas mineral products can give your plants that boost you’ve been looking for.

Your objective should be to find a middle-ground between large yields without losing out on flavor or effect. Less it not always more, and vice versa. Also, keep in mind that miracles don’t exist. The secret to getting the treasure you want is practice, taking care of your plants, and patience. Make sure to learn from your mistakes!
