cannabis yield per plant
Learn what cannabis yield per plant really looks like indoors, outdoors, and in greenhouses, plus the factors that raise or lower your final dry flower weight.
A well-grown high yielding cannabis strain usually returns about 400 to 700 grams (14 to 25 ounces) per plant outdoors and roughly 100 to 300 grams (3.5 to 10.5 ounces) per plant indoors under a strong light. Those ranges describe the cannabis yield per plant of high yielding strains under good conditions rather than a promise, because light, space, and grower skill shift the result more than genetics alone.
What "yield per plant" actually measures
Yield per plant is the dried, trimmed flower weight from one plant at harvest. It is not the same as yield per square foot, which is how commercial rooms are judged. A single plant in a large container with a long vegetative stage can outproduce four small plants in the same footprint, even when the genetics are identical.

Growers report weight after drying and curing, when flower has lost most of its water. Wet weight can look two to three times larger, so compare numbers only when they are labeled dry.

Typical ranges by setup
- Small indoor tent, short veg: 30 to 60 grams per plant
- Standard indoor room, 4 to 6 weeks veg: 80 to 150 grams per plant
- Large indoor plant with training and long veg: 250 to 500 grams per plant
- Outdoor plant in a good climate: 300 to 700 grams per plant
- Outdoor plant in a long season with a big root zone: 700 grams to well over 1 kilogram per plant
Outdoor plants generally win on total weight because sunlight delivers more usable energy across a full season than most indoor fixtures. Indoor plants win on consistency, since you control light cycles, temperature, and humidity.

Traits shared by high yielding strains
Genetics set the ceiling. Strains that produce heavy harvests usually share a few features:
- Vigorous vegetative growth with thick stems that hold up heavy colas
- Short internodal spacing, so flower sites stack instead of stretching
- Large, dense top colas plus solid secondary buds
- Strong mold and mildew resistance, which protects weight late in flower
- A high calyx-to-leaf ratio, which means less trimming loss
- Reliable photoperiod response and stable finishing times
Modern hybrids often pair these traits with high THC content, so a heavy harvest does not automatically mean weaker flower.
What moves your number most
- Light: Daily light integral drives biomass more than any nutrient bottle. Weak light caps yield no matter the strain.
- Vegetative time: More weeks of growth means more nodes and more flower sites.
- Root space: Container volume limits how large a plant can get.
- Training: Topping, low stress training, and screen setups spread canopy and expose buds to light.
- Environment: Stable temperature, humidity, and airflow prevent stress and mold.
- Harvest timing: Pulling too early cuts weight and potency at the same time.
Yield versus quality
Chasing maximum weight can dilute quality if plants are pushed with excess nutrients or harvested late. The best results come from healthy plants grown in the right environment, then dried slowly and cured properly. A 200 gram harvest of dense, well-cured flower is worth more to most people than 400 grams of airy, harsh buds.
Before you plan a grow
Home cultivation rules vary by state and by county, including plant counts, canopy limits, and whether growing is allowed at all. Check your local law first, and treat published yield figures as a planning estimate rather than a guaranteed outcome.
