Six Phenomenal Ways To Measures Cannabis Yields Indoors

To become a successful grower, you have to set an important KRA for high-quality indoor cannabis – maximizing yield! 

Whether you’re growing a few plants or a bunch, you surely want more buds with the same efforts. 

Want to earn bragging rights as one of the top-growers? Follow my lead and check out this post!

Starting with indoor cannabis cultivation


Your ability to measure the indoor cannabis yields gives you one of the crucial bragging rights as a top grower. Moreover, by knowing how many buds your grow-spaces produce, you can boost your growing process accordingly. 

One important thing worth considering is the seed quality. You should always get top-quality seeds from sites like

A transparent idea of your yield takes you a level up as a commercial grower by making valuable projections for your harvest. This projection helps you to reduce your overhead expenses and increase the overall yield. 

Interesting, isn’t it? 

With the passing decade, cannabis growers have experimented and succeeded in various ways to make their growing process more efficient. Now, the master growers have unleashed their secret techniques, or what you can call legacy! These easily accessible techniques can be used even by the most inexperienced growers with minimal or no hassle. 

With rapid progression in the cannabis industry, the demand for high-quality cannabis yields has increased significantly. This demand has led to the maximization of yields for every growth cycle like never before. 

You don’t want to stay behind, right? So, check the prominent ways used by master growers to measure cannabis yields successfully.  

Way 1: Grams Per Plant


Are you ready, grower friends? Time to focus and start! Let’s Go!

Growers mostly use this method to measure the yield of how many grams of buds they produce from each plant. 

Don’t worry if your math is weak! It’s no rocket science! 

You have to simply calculate the total weight of the buds harvested from a single cannabis plant after drying it. This way, you can be clear about your plant’s size but not certain about the actual yield of your grow space. 

If a cannabis plant produces 15 grams of bud, its size should be more than the plant that produces 6 grams of bud. Now, if you take my advice (which you should), go for something creative! 

You can fit more small-sized cannabis plants than bigger ones in a grow space of equal size. When considering the numbers, you will end up with a bigger harvest.

If you compare two similar-sized grow rooms with different numbers of plants, you will make the calculation for yield in grams per plant even more complicated. So, avoid that, folks!  

Way 2: Grams Per Square-Feet


Growers! Hold your horses as this second way is going to blow your mind!

The number of buds produced per square foot in a grow space is another parameter used to measure cannabis yield successfully. 

Sounds more practical, right? Indeed, it is! 

Here, you can compare two grow rooms with equal dimensions under different growing conditions to evaluate the yield performance. 

Based on the growth space size that you used, you will calculate your productivity. The calculation is simple, so stay with me, folks!

You simply divide the total production weight by your growing space’s square footage. 

This means, 

Yield for gram per square feet = Total production weight of dried bud (in grams) / Grow room’s square footage (in sq. ft)

However, I need to share something with you folks! 

Master growers added a note to this method. They say that it has the shortcoming of missing out some factors into account like light costs, etc., which can influence the plant’s growth. 

Way 3: Grams Per Cubic-Feet  


Leveling up skills as a cannabis grower is fun, right? Now, moving onto the third method used by master growers, it’s somewhat similar to the method discussed above but with a twist in grow space. The method to calculate yield is to calculate the weight of dried buds produced per cubic foot. I personally love this method too! 

No worries, as calculating yield with this method will be much easier if you follow my lead again! Here, you have to consider the plant’s height as a crucial indicator for the plant’s growth. Simply divide the dry buds’ total weight by your grow room’s cubic footage.  

This means, 

Yield (grams per cubic feet) = Total weight of dry bud (in grams) / Grow room’s cubic footage (cu.ft)

Do you use vertical farming techniques? If yes, you can use this method as it’s more practical.  

Way 4: Grams Per Watt


Now, I am going straight and concise, guys! Buckle up!

You can measure cannabis yields by the method of gram per watt of light too. Here, you divide the total weight of the dry buds by the used wattage of the grow lights. 

In simple terms, yield is determined by dividing the total weight of buds produced by total lamp wattage. 

Yield (Gram Per Watt) = Total Weight of Dry Bud (grams) / Total Light Wattage (W)  

Note it, guys! This method allows you to consider the output and intensity of the grow lights. 

For instance, let’s assume you have a 600W grow light in your grow room and produce 300 grams of dry bud. Here, your yield will be 300g/600W = 0.50 g/W.

Way 5: Grams Per Light (Kilowatt-hour)


Guys! This one is going to be a bit long. But trust me, it’s worth the read till last. I found the best success rate with this method!

The last method used by excellent cannabis growers to measure cannabis yields is calculating in grams per kilowatt-hour. This is a recognized cannabis industry standard to calculate cannabis yields and to know the productivity margins. 

Things are going to get easy but intense, so follow on!

The bud production rate gets directly impacted by the amount of light in the growing room setup. The amount of electricity becomes a relevant and crucial factor as the growth lights electricity to run. 

Here, yield is determined by dividing the total bud production weight by the total daily energy consumption. Daily energy consumption/usage is calculated by multiplying the light wattage by the number of hours for usage.  

Yield (in gram per kilowatt-hour) = Total dry bud weightage (in grams) / Total daily energy consumption (in kWh)

I have made an example for your easy understanding. Check out!

Let’s assume you use 250W lights for 12 hours daily, you harvested 500 grams of dry buds, and your growth cycle ends at 70 days. 

So, daily energy consumption/usage = 2(250W) * 12 hours = 6000 Wh = 6kWh

Total daily energy consumption/usage = 6 * 70 = 420 kWh

Yield = 500 grams / 420 kWh = 1.19 g/kWh

This method gives you the most comprehensive and distinct approach to determine your indoor cannabis growth yield. So, friends, if you want to be a successful commercial grower, this method is the right approach for you!

Way 6: Grams Per Day


This is a common yet effective method to determine how your yields come up at different times of the year. This method is simple but needs a bit of focus! Can I get it, growers? I presumed yes too!

Discover what your growing season was before jumping into the calculation. This is what experts say, not me. First, check the journal, take the date when you first planted the seed, and subtract it from the final harvest date. This will help you determine the number of days needed for the growing season. 

For instance, if you planted the seed on May 14, 2021, and harvested it on September 11, 2021, your growing season would be 120 days. 

Now, let’s say your plant’s average weight is 60 grams. Divide that by the growing season, which gives (60/120 = 0.50).

Now, let’s assume that your plants won’t be ready for harvest until September 22, making your growing season 131 days. (60/131 days = 0.45). This indicates that a longer growing season results in lesser cannabis yield per day. 

Final Thoughts 

Now that you are well-acquainted with all these methods measuring your cannabis yields won’t be much of a problem. Maximizing your yield will be easy, like child’s play. So, roll your sleeves! Get… Set… Grow!
