# How Much Weed Can One Marijuana Plant Yield?

We all want to get the biggest yield out of our marijuana crop especially since growing it requires hard work. But more importantly, we want to be able to enjoy its benefits as much as we can. To help us achieve this goal, we need to have a baseline on how much weed to expect come harvest time. Ultimately, this information will help guide our work to get the most out of the crop.

So, exactly how much weed can one marijuana plant make? Interestingly, there are many answers to this question. But the biggest determinant is the light that nourishes the cannabis plants. Typically, a brighter light will encourage the plant to produce bigger and denser buds. Similarly, a spacious grow area will help the roots grow longer which results to a more productive crop.

Not surprisingly, using high-quality soil and fertilizer will also lead to bigger yields. As we can see, many variables can affect both the quantity and quality of the weed we can harvest. Therefore, we will focus on them to get the nearest estimate of the yield.

So, this article will cover the many ways to gauge the yield of marijuana based on the environment that we provide. Moreover, we will look at the basic considerations before planting to get most of the crop. Finally, we will learn how to make one cannabis plant produce as much as possible every harvest time.

## How to Estimate Marijuana Yield Base on the Environment

The easiest way to predict the yield of a marijuana plant is to pay close attention to its surroundings. Hence, this section will present the many methods of estimating the average expected harvest based on the grow situations.

**Indoor Yield**

An indoor cannabis garden has significantly different variables from an outdoor one. Add to that, the variety of grow mediums to choose from have different rates of absorbing nutrients and oxygen. But mainly, the types of light we use directly influence the speed at which the plants flower. All in all, these factors play huge roles in the final yield.

**Grow Light and Space**

Generally, an expert indoor grower can produce 1 gram of buds per watt of an HPS light. So, a 400 watt has the potential to turn out 400 grams or 14 ounces of dried marijuana. For best results, we should utilize certain light wattage for a specific grow area. To get a clearer picture, the following information shows how much buds we can get in varying specifications.

**Expected Yield in Imperial Measurements**

A 3.5 x 1.5 x 6.5-foot grow cabinet and a 200-watt CFL lamp will give 1.5 to 2.0 ounces of weed or 3.5 oz for advanced growers.

Using the same grow space but with a 250-watt HPS, expect to get 3.0 to 5.0 ounces or 9.0 oz for advanced growers.

On the other hand, a 3.5 x 3.5 x 7-foot space and a 400-watt HPS will provide 4.5 to 9.0 ounces of weed. But for advanced growers, the yield is 14 ounces.

When the grow room is 4 x 4 x 8 feet with a 600-watt HPS lamp, expect to get 5.0 to 10 ounces of weed. Advanced growers can easily get 21 ounces.

Finally, in a 5 x 5 x 8-feet grow space with 1000-watt HPS, the yield goes up to 9.0 to 18 ounces and 36 for advanced growers.

**Expected Yield in Metric Measurements**

A grow cabinet size of 1 x 0.5 x 2 meters with 200-watt CFL lamp will make 40 to 60 grams of weed. Seasoned growers can get as much as 100 grams.

However, if we use a 250-watt HPS light, the yield goes up to 80 to 150 grams and 250 for the experts.

A bigger grow room such as 1 x 1 x 2.5 meters and 400-watt HPS will provide 100 to 250 grams of weed. The same specifications will get advanced growers 400 grams.

Increasing the space to 1.2 x 1.2 x 2.5 meters and light to 600-watt HPS will get us around 150 to 300 grams or 600 for advanced growers.

Finally, a grow room that measures 1.5 x 1.5 x 2.5 meters and a 1000-watt HPS lamp will yield 250 to 500 grams of usable weed. Expert growers will get around 1000 grams.

**Grow Medium**

Depending on personal preferences and availability of resources, we can select which grow medium works best for us. Since no two mediums are alike, anticipate getting less or more yield.

**Hydroponics**

If we want the plants to grow fast and produce denser buds, hydroponics is the way to go. In fact, on average, we can get 20% more weed using this medium than soil. However, disastrous outcomes are more frequent in hydroponics. Since the roots come in direct contact with the nutrient solutions, then a minor mistake can have devastating results.

But if we do things properly, then we can get 1.2 grams of weed per watt of light. This means that 600-watt of HPS lamp can give 720 grams or about 25 ounces. So, make sure to develop the skills of checking and correcting the pH and TDS values when deciding to go with this one.

**Soil**

Expect to get lesser yield in soil since it acts as a buffer to the nutrients, making the absorption rate much slower. The maximum yield is 1 gram per watt, which means that 600 watts of HPS lamp will produce 600 grams or 21 ounces of weed.

The upside is that there’s a lot of wiggle room in using soil. As such, big mistakes in nutrient feeding and watering are easy to correct. Because of its flexibility, newbie growers usually find more success in this medium.

**Outdoor Yield**

Under perfect conditions, an outdoor marijuana plant can make up to 500 grams or 17.5 oz of weed. As mentioned, ample space is vital for the plants to flourish. This means that each plant must have at least 2 meters or 50 liters of soil in a container.

## How to Optimize Marijuana Yield

Now that we know how much weed to expect in one plant, let’s learn how to boost the yield.

**Plan the Basics**

In growing weed, setting plans on how to tackle the process increases our chances of success. This begins with choosing the seeds that have the best genes. Obviously, a high-quality seed will grow better, faster, and produce more than inferior ones.

Another essential part of planning is deciding how many plants to grow. A good guideline is to consider what happens when we grow only 4 plants. If one gets sick and die, we will then have 25% less yield. Also, this number tend to take longer to enter the flowering phase since their leaves don’t touch as fast when there are more plants.

On the bright side, 4 plants are easier to manage compared to 16 plants. In addition, it’s easier to hide 4 cannabis plants than 16.

**Maximize Space and Grow Area**

The photo above is one marijuana plant under a 600-watt light. To get this kind of productivity, use at least a 4 x 4 foot grow tent and a 600-watt HPS light. Under perfect conditions, we can get over a pound of weed per one plant when we focus the light on it.

While getting this kind of yield seems exciting, it takes a lot of pruning and longer vegetative time. Also, in the unfortunate moment that it gets sick, we will be left with no replacement.

**Use Screen of Green Method**

An excellent way to increase the yield up to 10-20% is to utilize the SCROG technique. However, we will need to master the basic grow skills such as watering and pruning to get this right.

To apply it, place a screen 15 inches above the plants and tie the branches once they grow 4 inches through the screen. The idea is to spread the branches so that all leaves will get the same amount of light, resulting to a more rapid and productive growth.

## Environmental Factors Dictate How Much a Marijuana Plant Yields

Basically, how much weed a marijuana plant makes depends on several variables.

This includes light, water, nutrition, air, and space to spread its roots and leaves. Of course, we can expect a bountiful yield when we provide all the requirements. As such, the key is to make sure that the plants get the optimum level of care.

As we know, being well-informed always bear satisfying outcomes. So, know the facts and have a more productive crop by using this article as a guideline. Having an idea on how much yield to expect points us to the right direction. So, get a clearer vision of the results and pair it with hard work to get the best harvest possible.
