How much marijuana will a single plant yield? It might be the most popular question about growing marijuana but there are no simple answers to this question as each situation depends on a number of variables. Yields of up to a pound per plant are possible!
If you want to take your growing to the next level and ensure ample weed for whatever purposes you have in mind, read through this information and get your gardening going.
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.
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 lamp in 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 2 m
- 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.
Maximum yield per plant
You’ll notice the yields described above aren’t certain. Indoor growing brings with it a great deal of uncertainty when it comes to yield. Light, of course, is important. You’ll get a better yield per plant with a smaller number of plants per lamp, and four plants is a whole lot easier to manage than sixteen. Here are some more things to consider:
- 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.
- While we’re on that subject, with only four plants, your crop will be ruined if even one gets a disease or dies.
- You can manage four plants far more easily than sixteen.
- If you’re not exactly interested in government officials discovering your grow room, keep in mind four plants to your name is significantly better than sixteen if you should be caught.
Think of your yield this way. If you use a 600-watt HPS lamp and have four plants, you could expect up to 5.0z per plant. If you have sixteen plants with the same lamp, you could expect up to 1.25 oz. per plant. The four plants produce a total of up to 20 oz but so do the 16. If you use the same lighting and grow only one huge plant in a large container, you could see a yield as high as a pound!
You just read that one large plant indoors can yield up to a pound of weed. How much can an outdoor marijuana plant yield? It can be the same as long as the conditions are right. If the conditions are perfect, you could see yields as high as a pound of grass per plant.
The plants will need at least two meters of space, ample water, nutrients, and freedom from pests and diseases. Use containers at least fifteen gallons (or 50 liters) if you’re growing in containers, and be sure to germinate the seeds early. That will allow the plants to grow large, and you should germinate them indoors to regulate growing conditions for the seedlings. If everything goes as planned, you’ll have a heck of a lot of weed.
Now might be a good time to point out that the quality of the seeds can make an impact on your yield. Like any plants, genetics play an important role. Make sure t buy high quality seeds and find the perfect strains for your area.
What is the difference between wet and dry weed
When you dry weed, you lose weight because the water evaporates. In fact, you lose about 75 to 80% of the weight. There are some things that can help though.
Dry your weed slowly over ten to fourteen days in a dry place with a controlled temperature (around 64 degrees) and you’ll get you more weed in weight.
Here are some expected dry yields. Out of a well cultivated Sativa you will get approximately 20% -22% dry weed and from an Indica about 22% -25%. So out of one pound of wet Amnesia Haze you will get approximately 7.4 ounces and if you dry one pound of White Widow you’ll get about 8.4 ounces. At a street price of $ 7 (Oregon) or $12 (Texas) this is very good profit.
If you consider the entire weight of the plant, you can expect 12.5% of the weight (including stems and leaves) of a wet plant.
