How much does one weed plant produce? We all want to get the biggest yield out of our marijuana crop especially since growing it requires hard work. But more importantly, we want to be able to enjoy its benefits as much as we can. To help us achieve this goal, we need to have a baseline on how much weed to expect come harvest time. Ultimately, this information will help guide our work to get the most out of the crop. So, exactly how much weed can one marijuana plant make? Interestingly, there are many answers to this question. But the biggest determinant is the light that nourishes the cannabis plants. Typically, a brighter light will encourage the plant to produce bigger and denser buds. Similarly, a spacious grow area will help the roots grow longer which results to a more productive crop. 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.
How much marijuana can you yield indoors? Maximum indoor yield
Growing marijuana indoors is often necessary, but the key to success is simulating an outdoor growing environment. For example, lights are very important. Ever tried to smoke a joint without a lighter? That's what it's like for an indoor plant without light. If you get good at growing, you can expect to see your plants produce about a gram of weed for every watt of light (1 gram = 0,035 oz). To put that in perspective, a skilled grower can use a 400 watts HPS grow light to produce 400 grams of pot. That works out to about 14 oz. Want more? Get more light. A grow room with 1200 watts can lead to a yield of 42 oz. Get the right light but don't forget you'll also need the right nutrients, the right equipment, good air quality, a good room for the plants to grow in, and plenty of time for the attention you'll need to give it if you want the highest possible yield. Making sure your plants have enough space is key.
You should read the article Create the perfect environment for your marijuana plants if you want to know the right temperatures, humidity levels, CO2, air flow etc. Here's what you can expect if you follow the basic instructions:
Yield in ounces
An average of around 1.5 to 2.0 oz (3.5 oz for experienced growers) with 200-watt CFL lamps in a grow cabinet that measures 3.5 x 1.5 x 6.5 ft. An average of around 3.0 to 5.0 oz (9.0 oz for experienced growers) with a 250-watt HPS lamp in a grow cabinet that measures 3.5 x 1.5 x 6.5 ft. An average of around 4.5 to 9.0 oz (14 oz for experienced growers) with a 400-watt HPS lamp in a grow room that measures 3.5 x 3.5 x 7 ft. An average of around 5.0 to 10 oz (21 for experienced growers) with a 600-watt HPS lampin a grow room that measures 4 x 4 x 8 ft. An average of around 9.0 to 18 oz (36 for experienced growers) with a 1000-watt HPS lamp in a grow room that measures 5 x 5 x 8 ft.
By now, you should have figured out two things. Light is critical, and becoming a experienced grower gets you more grass. Here's what you can expect with metric measurements for the growing area.
Yield in grams
An average of around 40 to 60 grams (100 for experienced growers) with 200-watt CFL lamps in a grow cabinet that measures 1 x 0.5 x 2 m An average of around 80 to 150 grams (250 for experienced growers) with a 250-watt HPS lamp in a grow cabinet that measures 1 x 0.5 x 2m An average of around 100 to 250 grams (400 for experienced growers) with a 400-watt HPS lamp in a grow room that measures 1 x 1 x 2.5 m, An average of around 150 to 300 grams (600 for experienced growers) with a 600-watt HPS lamp in a grow room that measures 1.2 x 1.2 x 2.5 m. An average of around 250 to 500 grams (1000 for experienced growers) with a 1000-watt HPS lamp in a grow room that measures 1.5 x 1.5 x 2.5 m.
Average expected yield when grown indoors in soil
If you are using soil to grow indoors, you can expect somewhat less of a yield than if you'd grown hydroponically. This is because hydro growers can fully control the amount of nutrients their plants receive.
Although soil growing can potentially lower your yield, it also is easier to grow. This is because it not only creates a buffer for error, but it also holds nutrients within the soil. When growing in soil, there is room to make mistakes with pH and TDS and pay for it in yield. In terms of numbers, expect a maximum of 1 gram per watt. That means a 600watt lamp can produce 600 grams of marijuana or 21 ounces.
Yield even more when growing hydroponically
Growing hydroponically yields up to 20% more, as long as you do not make any mistakes. With hydroponic growing, there is no room for errors. You must be very careful about the TDS and pH levels because the roots are directly in water (and not soil) and incorrect levels can immediately affect the plants. There are rarely small mistakes while growing hydroponically. Even the most minor error can ruin your yield. However, those who do it correctly will be rewarded. You can expect up to 1.2 gram per watt, which means a 600watt HPS lamp can give you 720 grams of marijuana or over 25 ounces.
Maximum yield per plant
Indoor growth doesn't bring with it a lot of certainty in terms of yield per plant. If you have only four plants per lamp, then you'll yield much more than you would with total of sixteen plants for every lamp. You should consider these things prior to choosing how many plants you want to grow:
If you've only got 4 plants, your crop will be ruined if even one gets a disease or dies Vegetative growth lasts longer with only four plants. You should want to force flowering when the tips of the leaves are touching. If there are more plants, the leaves touch quicker. Four plants are easier to manage than sixteen. If someone catches you, you only have four plants to your name.
Either way, growing four plants using a 600-watt HPS grow light could produce about 150 grams or 5.0 oz per plant. Sixteen plants that are grown under a 600-watt HPS lamp could produce about 37.5 grams or 1.3 oz of marijuana per plant.
How much marijuana can you yield outdoors? Under perfect conditions, you can expect yields to extend to 500 grams or 17.5 oz of marijuana per plant. Space is a necessity (at least two meters) along with water, nutrients, and a dearth of pests and diseases. If you use containers, they should be at least 50 liters or 15 gallons in size. It's a good idea to germinate the seeds early on to allow the plants time to grow large. It's best to germinate indoors where you can manage the
humidity and the temperature for the seedlings. Again, 500 grams (17.5 oz) per plant is possible if everything goes as planned. Aside from an adequate amount of sun, water, and nutrient quality, the actual genetics of the plant play a very important role. Seeds are vital, and you need to have some exceptional seeds at your disposal. Browse my seed selection to find the strain that's right for you.
Environmental Factors Dictate How Much a Marijuana Plant Yields Basically, how much weed a marijuana plant makes depends on several variables. This includes light, water, nutrition, air, and space to spread its roots and leaves. Of course, we can expect a bountiful yield when we provide all the requirements. As such, the key is to make sure that the plants get the optimum level of care.
