Did you give your plant a 2, 3, 4 or 5 gallon pot, or a 10 gallon pot? The bigger the pot, the bigger the plant. Lighting is another key ingredient to increasing your plant yields. If you grow with a cheap LED Light, you’ll diminish the plant’s yield potential. You’ll want to grow with a high quality LED light to get the most amount of yield per plant indoors.
You can lessen your plants yield potential by not properly caring for your plant indoors. Plant care includes the quality organic nutrients and water it needs to survive and thrive. It may include plant training techniques like topping, pinching and supercopping, all to grow bigger plants. If you don’t practice proper plant care, you won’t get as much of a yield per plant.
They often reference a yield algorithm based on things like how big your grow room is, what lights you are using, how many watts, and more. Not helpful. An answer like, “A grow room with 1200 watts can lead to a yield of 42 oz.” or “you can grow 1 lb. per plant,” not only sets false expectations, it confuses new cannabis gardeners who are trying to grow in grow tents with LEDs.
Where and how you grow is a crucial factor to get to the bottom of your question, “how much does an indoor cannabis plant yield?” The strain you grow is also an influential factor. Additionally, you must consider how long you are growing your plant in the vegetative phase. People who grow cannabis plants with over 10 ounces are usually keeping their plants in the vegetative phase for more than 10 weeks. Do you have the time?
You see, it depends on whether you are growing small plants, medium sized plants, large plants, or extremely large plants. The size of your pot must be taken into consideration, and there can be a big difference in the size of your harvest (yield), depending on if you are growing in a grow tent or in a grow room with high ceilings.
But that doesn’t mean you can’t figure an answer to this common question about plant yield indoors. There are a lot of moving parts in your gardening process that influence yield per plant. To get close to a perfect estimate, you’ll need to know if you are growing in a small tent, large tent, or in a grow room. If you are growing in a small grow tent, you may be growing small to medium size plants. You may have 6 short plants or 3 short to medium sized plants, 2 big plants, or you may have 1 “large as you can get it” plant.
Plant genetics greatly influences how much a plant can yield. You can grow a “heavy yielding” or “heavy producer” strain, average yielding strain, or low-yielding strain. For example, the size of cola buds on a Dream Queen strain are much bigger than the cola buds of a Girl Scout Cookies strain. If you are unsure of your seed or clone origin before growing, that is a big risk to take if growing for heavy yields is your goal.
Home Grower Question: How much does an indoor cannabis plant yield?
With all that said about indoor plant yields, home growers who grow marijuana plants indoors in grow tents may yield from 1 – 5 ounces per cannabis plant, with a sweet spot of 2 – 4 ounces per plant. Honestly it depends on the above mentioned gardening and genetic factors, but this gives you a realistic snapshot of your cannabis yield potential.
Home growers who grow marijuana plants indoors in grow tents may yield from 1 – 5 ounces per cannabis plant, with a sweet spot of 2 – 4 ounces per plant.
When the grow room is 4 x 4 x 8 feet with a 600-watt HPS lamp, expect to get 5.0 to 10 ounces of weed. Advanced growers can easily get 21 ounces.
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.
Depending on personal preferences and availability of resources, we can select which grow medium works best for us. Since no two mediums are alike, anticipate getting less or more yield.
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.
Now that we know how much weed to expect in one plant, let’s learn how to boost the yield.
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.
The upside is that there’s a lot of wiggle room in using soil. As such, big mistakes in nutrient feeding and watering are easy to correct. Because of its flexibility, newbie growers usually find more success in this medium.
Another essential part of planning is deciding how many plants to grow. A good guideline is to consider what happens when we grow only 4 plants. If one gets sick and die, we will then have 25% less yield. Also, this number tend to take longer to enter the flowering phase since their leaves don’t touch as fast when there are more plants.
