How Much Weed Can You Get From Growing One Plant

So you’ve embarked on the journey of growing your own cannabis plant – kudos to you! Whether you’re a seasoned professional or a newbie, nothing compares to the thrill of growing your own stash. 

As you venture into this green realm, you may wonder what kind of yield to expect from your plant. Estimating one plant’s yield is not an exact science and depends on several factors.

We’ll help you understand exactly what affects your plant’s growth and what you can do to maximize your yield. 

What Is Cannabis Plant Yield?

When we talk about the yield of a cannabis plant, we’re referring to the amount of usable cannabis that you can harvest from a single plant. Optimizing your plant’s yield involves working on several fronts at once. Some elements that affect the size of your yield are:

  • The genetic strain of marijuana
  • The plant’s growing conditions
  • How you train your plant’s growing pattern

A very broad average of the yield of one indoor, medium-sized, healthy weed plant is a quarter pound weed or 112 grams. One outdoor, medium-sized, healthy weed plant will, on average, produce half a pound of weed or 224 grams.

Before you eagerly rush off and start preparing to grow your own leafy jungle, remember to research how many plants you can legally grow in your state or country. In most states in the USA, you can legally grow up to 6 plants and own a few ounces of weed. 

While the federal government has still outlawed cannabis, each state has its own laws around cannabis possession and use.

Estimating Yield Potential

Estimating your yield potential requires a mixture of experience, science, and a dash of intuition! There are various techniques for estimating your yield while growing your plant. 

  • Experience and observation: Experienced growers often rely on their past harvests and observations to estimate future yields. Pay attention to factors like plant genetics and how they’ve responded to different setups.
  • Scientific principles: Understanding the basics of how cannabis grows can give you some valuable insights. Knowing about things like plant biology, environmental conditions, and nutrient needs can help you make smarter decisions that could affect your final yield.
  • Quantitative methods: Some growers like to get more technical with their yield estimates. They might measure things like grams per watt of light or grams per square foot of growing space to get a better idea of how efficient their setup is.
  • Environmental factors: Factors such as temperature, humidity, air circulation, and CO2 levels can significantly impact plant growth and ultimately yield. 
  • Genetics and strain selection: The type of strain you’re growing can also play a role in how much bud you’ll end up with. Some strains are known for bigger yields, while others might not be as prolific. Choosing the right strain for your setup and goals is key.
  • Intuition and adaptation: Trust your gut! After spending time with your plants and getting to know them, you’ll develop a feel for what they need. Don’t be afraid to make adjustments along the way based on what your intuition is telling you.

By combining these different approaches, you’ll be better equipped to estimate your cannabis yield and make informed decisions throughout the growing process

What Determines Weed Yield? 

The factors determining your weed yield are the same as those to consider when estimating your yield potential. But you can optimize each of these factors to give you the most bang for your buck. 

Strain Genetics

The genetic makeup of your chosen cannabis strain plays a pivotal role in determining your ultimate yield. Some strains are naturally more prolific, producing larger and denser buds.

Sativa-dominant strains have a bigger yield with shorter, more solid buds. On the other hand, indica-dominant strains produce a lower yield with longer, more feathery buds. But this is a very broad generalization and you will indica-forward strains that will far surpass their sativa-dominant friends.

Research different strains to find one that suits your cultivation goals, whether that be maximizing yield, potency, or a specific flavor profile. 

Growing Medium

The medium in which your cannabis plant grows significantly affects its development. The two most popular growing mediums are soil and hydroponics. Each one has its benefits and downfalls, so choosing one is really up to you.

Soil

Soil provides a more natural environment that is already rich in nutrients. These ingredients are freely available in most soils, but they take time to be absorbed. Live organisms in soil convert raw nutrients to plant-soluble food.

Growing your cannabis plant in soil is more affordable, and more eco-friendly, and there is less room for any nutrient errors. Plants grow more slowly in soil, they are exposed to naturally occurring pests, and challenges with the pH levels take longer to correct.

Hydroponics

Setting up a hydroponics system is a lot more expensive upfront, as all the gear is specialized. This means that scaling your cultivation project is not as easy as a soil garden. But plants grow faster with this method, and it is a lot easier and faster to correct any nutrient deficiencies or pH imbalances.

Correcting issues relating to pH and nutrients in a hydroponic system is fast and easy. But this also means that over-correcting any issues happens more often. This could lead to the opposite problem: nutrient lockout.  

Lighting

Light is the most important energy source for all plants, and it plays a crucial role in photosynthesis. The cannabis plant does the best with plenty of full sunlight. So the type of lighting you choose will significantly affect your plant’s yield. 

If you choose to grow an outdoor garden, you don’t have to think much about lighting. Your garden will make use of the sun’s natural light. If you are living in a country with a lot of natural light, then your plants will thrive.

Indoor gardeners have a few more choices at their fingertips. Two popular options are High-Intensity Discharge (HID) and Light Emitting Diodes (LED) lamps. 

HIDs are a staple in the industry and have been around for a long time because of their strength of emissions. They promote vigorous growth and ample flowers. 

If you are looking to light a smaller garden, LEDs might be better suited to you because they are more energy efficient. LED lamps are often spectrum tunable, meaning that you can adjust the color of your light for the different stages of your plant’s growth. 

Cannabis plants do blossom with plenty of light, but be careful not to overdo it or they might burn. If you are cultivating an indoor garden, try to match up the combined power of your lighting with the amount of plants.

Environment

Whether you choose to grow your cannabis outside or indoors, maintaining a relatively consistent environment is crucial for a successful harvest. When your plant’s environment is stable, it minimizes stress and helps promote robust growth. 

For growers, cultivating outdoors and maintaining a stable environment can be difficult. Sudden heat waves or cold fronts are out of your control and can damage the health of your plant. Growing cannabis in a greenhouse can help to mitigate these factors.

One of the biggest advantages of indoor gardens is that they offer full control over your plant’s environment. You can monitor the amount of light, the amount of nutrients, and the space that your plants receive. Just be sure to ventilate your indoor garden so that it has a constant flow of air to prevent mold.

Temperature And Humidity

Maintaining the right temperature and humidity levels is vital throughout the plant’s life cycle. Cannabis plants prefer temperatures between 70 – 85°F (or 21 – 29°C) during the day and are slightly cooler during the night. 

Humidity levels also play a significant role in your weed plant’s yield. During the vegetative stage, cannabis plants thrive at a higher humidity level of approximately 40% – 70%. As the plants transition to the flowering phase, gradually reduce the humidity to 40%-50%. 

Controlling humidity prevents issues like mold and bud rot, especially in the denser bud formations. 

Like many of these aspects affecting your weed plant’s yield, getting the optimal temperature and humidity is a balancing act. Hot temperatures, especially coupled with high humidity, can create a breeding ground for pests and diseases.

On the other hand, low humidity can lead to the plant drying out through excessive transpiration. This will stress your plant out and lower your yield. 

Nutrients

Nutrients play a crucial role in cannabis growth and development, influencing various aspects of plant health, vigor, and ultimately yield. 

Providing the right balance of nutrients throughout the plant’s life cycle is essential for maximizing yield potential. 

Different stages of growth require different nutrient ratios, so it’s important to follow a feeding schedule appropriate for the cultivation method you choose.

The pH level of the growing medium influences nutrient uptake. Cannabis plants prefer a slightly acidic pH range of 6.0 to 6.5 for optimal nutrient uptake. pH levels outside of this range can lead to nutrient deficiencies or toxicities, affecting plant growth.

Growing Techniques 

Another way to help your plant produce a larger and higher quality yield is to employ certain growing techniques. There are various methods of achieving this during the vegetative growth stage. 

  • Sea of Green (SOG) Technique involves aiming for quantity over quality. Growers cultivate many smaller plants in a confined space. These plants have a shorter vegetative stage and are induced into their flowering stage early. This method is best for growers who want to minimize their growth time while maximizing their yield. 
  • The Screen of Green (SCROG) Technique uses a screen or net to control the height of your plant’s canopy. As the plants grow through the screen, their branches are trained to grow horizontally. This method allows light to reach the buds lower down on the plant and helps them to develop equally. 
  • Low-Stress Training (LST) involves gently bending and tying the topmost branches of your plant down to create a wider and more even canopy. Similar to the SCROG technique, LST works with the goal of increasing the amount of light reaching the lower part of the plant. LST is considered a less intrusive growing technique than High-Stress training. 
  • High-Stress Training (HST) is more intrusive and aggressive. It involves using techniques like topping, fimming, and super cropping. These pruning measures intentionally stress your plants out and redirect their energy. HST encourages bushier and more robust growth, but it can easily be overdone and harm the plant. 

Harvest Timing

Timing is crucial when harvesting weed. Always keep an eye on the trichomes of the plant. The trichomes are those tiny, bead-like structures on the end of the buds. They contain most of the cannabinoids, terpenes, and other compounds responsible for the effects and aroma of cannabis. 

When the trichomes change color from clear to cloudy or amber, then the plant is ready to harvest. Harvesting during the cloudy trichome stage is preferred for a balanced combination of THC and other cannabinoids, providing both cerebral and physical effects.

Accurate Measuring

Measuring your yield accurately is a vital part of the cultivation process. 

To get an accurate yield measurement, avoid weighing fresh flower. During the drying process, nugs will lose 70% – 80% of their weight to moisture evaporation. 

Once dried, carefully weigh your cannabis buds using a scale calibrated for accuracy. This measurement represents the dry weight of your harvest and provides a more reliable indication of your yield.

Conclusion

It is almost impossible to know exactly how much weed you will harvest from one plant. Your yield depends on several factors. The better you become at mastering these factors, the more your plants will reward you.

If your first harvest disappoints you, don’t lose heart! All the best gardeners took years to hone their craft.

But in order to know what high-quality bud smells like and tastes like, you must have some frame of reference. At Embarc, we offer only the finest cannabis for you to indulge in!
