how much marijuana from one plant

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.
Let’s also imagine that this cultivator takes care of his plants carefully throughout the growing period.

On the contrary, if all goes well, the grower can expect between 200 and 300 grams per square metre. But it will be necessary to avoid embarking on optimisations or advanced techniques.
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.

Let’s take an indoor plant again with a 400-watt lamp but now with a 40-day growth phase.

  • The type of culture: indoors or outdoors
  • Lighting power
  • Available space to the plant
  • Growth time
  • Temperature and humidity
  • Type of seeds
  • Fertilisers used to feed the plant
  • The culture technique used: one-bud, scrog, trellising, etc.

All plants depend on light, nutrients and water to achieve their optimal growth and potential in terms of harvest. Cannabis plants can be grown indoors or outdoors using many different horticultural methods, which all have an impact on growth, not even taking into consideration the natural variations in yield between strains.

The average yield over a cannabis strain depends on various factors. But how much weed does one plant yield? Check it out!

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.
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.

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.
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.
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.
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.

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.

The overall yield of the crop is the top priority of marijuana growers. To get maximum results, know exactly how much weed to expect in one cannabis plant.
