While soil is easily the most common medium used to grow cannabis, hydroponic media like perlite or coco coir give growers a lot more control over the nutrient intake of their plants. And while that kind of control may be overwhelming for rookie growers, experienced growers can use it to really push their plants to the next level and produce massive yields.
Growing hydroponically gives you a lot more control over how your plants feed. With the right equipment and experience, this can greatly improve the size and quality of your yield. Experienced hydro growers, for example, can encourage yields of up to 1.2g per watt of lighting. By this logic—and using a 600W lamp—a good hydro grower can harvest over 700 grams of bud (genetics depending)!
• Read up on training techniques. Training your plants to grow a certain way maximises their exposure to light, which will ultimately improve your yield.
• Start with the right genetics. Professionally bred strains will always produce better yields than bagseed.
While yields vary a lot, there are some ways you can get at least a rough estimate of how much weed you’ll produce.
Indoor growers generally have less space to work with, which means they’ll usually grow fewer, smaller plants than someone growing outdoors. However, indoor growers also have much more control over their plants’ environment. Hence, they can play around with things like lighting, temperature, and humidity to fine-tune their growing conditions and optimise yield.
There are many different grow media out there, and they all have different effects on the overall yield of your plants.
Most rookie growers estimate their yield based on the height of their plants. And that makes sense—at least in theory. Unfortunately, plant size isn’t a very accurate indicator of final yield. In fact, it’s really hard to estimate the size of your yield just by looking at a single aspect of your plant (like height, for example).
Arguably the most crucial factor that determines final yield are genetics. And just like there are some strains that taste better than others, there are also those that produce better harvests than others.

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.
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.
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?
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.
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.
Answer: The answer is not easy, but it’s honest. Plant yields vary due to many factors including the size of plant, which is to say, how big you let your plant grow. The quality of the plant’s genetics and propensity for the genetic’s yield — be it a low, medium or heavy producing strain, also greatly influence 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.
