Because plant size is so variable, it is not the best way to estimate yield. A much better method is to use the strength of your light. Using the size of your grow area works as well.
If you provide good growing conditions and you don’t make any big mistakes, you can expect a yield of about 1 gram per watt of light (0.035 oz/w). Thus, you can expect a yield of around 1000 g, or 1 kg, from a 1000 watt light.
Using The Size Of Your Grow Area To Estimate Yield
The numbers above all assume you know what you’re doing. If you’re a beginner with no experience growing cannabis, you will not likely see those kinds of yields. But it’s not that hard to come close, even if you know very little about cannabis cultivation.
You should also combine this with lollipopping, to make sure your strains use all of their resources for viable bud production, and don’t waste any energy on feeding areas that don’t get adequate light anyway.
LED lights have an actual wattage and a second number that is sometimes the HID equivalent, but often much higher than that. The second number is what the manufacturers usually use in the name, but it does not generally tell you much about the actual power of the light.
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 horticultural methods, which all have an impact on growth, not even taking into consideration the natural variations in yield between strains.
These estimates are presented in the form of scenarios, as in the previous section
Factors that determine the harvest of a strain
So how much does one plant yield? We’ll take a look at weed plants grown indoors under different light conditions to give you an understanding of how much weed an average weed plant can produce.
Many factors influence the weed production of a cannabis plant. The most important ones are listed below:
For beginners, six plants per square meter allow a relatively short growth phase of 4 or 5 weeks. This also avoids having to manage 10 or 15 plants in a first session.
