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.
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.
• Start with the right genetics. Professionally bred strains will always produce better yields than bagseed.
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.
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.
There are many different grow media out there, and they all have different effects on the overall yield of your plants.
• Experiment. Don’t be scared to try new grow techniques and push yourself as a grower.
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.
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.

The production of buds from a single plant will, therefore, be much higher than the previous scenario. You can expect between 40 and 80 grams of cannabis per plant if flowering takes place under optimal conditions.
Finally, let’s also suppose that this grower encountered some problems of too high temperatures or too low humidity.
In such a scenario, it is quite likely that the grower will make beginner mistakes. And these errors will cost much more than the potential gains that these optimisations could have delivered.
A short growing period shortens the total growing time. For a variety that flowers in 50 days, a growth of 15 days will allow harvesting in just 65 days or just over two months. The downside is that you will need many plants to fill a space of one square metre!
Let’s also imagine that this cultivator takes care of his plants carefully throughout the growing period.
Imagine an experienced cultivator who knows some cultivation techniques such as trellising or scrog.
During these 40 days of growth, the plant will have had time to develop a very dense root and leaf network, especially if the weather conditions are good. Some varieties will quickly reach a metre in height in 40 days of growth.
This is a complex topic and there are many other factors that can affect yields, such as hydroponics, which minimises the likelihood of errors and the type of seed used, which also has an impact on the amount of harvest. Some strains are much more high-yielding than others. Big Bud and Girl Scout Cookies, for example, are famous for their huge buds and generous yields.
The question most asked by beginner growers is how many grams of cannabis per plant can be harvested? A great question, yet hard to answer in a simple way, but certainly not impossible.
The average yield over a cannabis strain depends on various factors. But how much weed does one plant yield? Check it out!
