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.
Finally, let’s also suppose that this grower encountered some problems of too high temperatures or too low humidity.
This last cultivator could reach a record harvest of more than 650 grams per square metre.
You will have the opportunity to train your plant to give it the shape you want and to maximise the occupancy of the space. With this method, yields can reach up to 100 – 120 grams per plant.
The number of plants doesn’t really count. It doesn’t matter how many plants per square metre you grow. The goal is for the entire available surface to be covered by plants, which will allow the flowers to occupy all of the available space and thus maximise the production of weed.
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!
The harvest could also be limited to 50 or 100 grams of dry grass per square metre if something goes wrong during the cultivation.
In this configuration, if the grower takes care of the plants properly and there are no major incidents during cultivation, a cannabis plant can produce between 15 and 30 grams of cannabis per plant.
This cultivator can expect a harvest of 200 to 350 grams per square metre.
The average yield over a cannabis strain depends on various factors. But how much weed does one plant yield? Check it out!
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.

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.
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.
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.
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.
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.
