What Is the Average Weed Yield Per Plant?
A healthy cannabis plant grown indoors usually yields 1 to 2 ounces (28 to 56 grams) of dried flower. Outdoor plants commonly yield 3 to 4 ounces (85 to 113 grams) or more. These are averages across common photoperiod strains and standard grow setups, not guarantees. A single plant can produce 5 ounces indoors with strong light, training, and a long vegetative stage. The same plant can produce 1 ounce outdoors if weather, pests, or light exposure limit growth.

Average Yield by Grow Method
Indoor grows
Indoor yield per plant lands between 1 and 2 ounces for most home growers using a 2x2 or 3x3 foot tent. A 400-watt to 600-watt light with good airflow and a 4 to 8 week vegetative period supports that range. Sea of green setups with many small plants can hit 0.5 to 1 ounce per plant, but the per-square-foot yield matters more than per-plant yield.

Outdoor grows
Outdoor plants average 3 to 4 ounces in full sun with a long season. In warm climates with a 6-month grow, a single plant can reach 8 ounces or more. Cold nights, short seasons, and heavy rain cut yield. Autoflowering plants outdoor often finish at 1 to 3 ounces.
What Changes Yield Per Plant
- Light intensity and hours: more light means more flower sites.
- Vegetative time: longer veg builds more branches and bud sites.
- Genetics: high-yield hybrids outperform low-yield landraces.
- Container size: larger pots support bigger root systems.
- Nutrients and pH: steady feeding prevents stalls.
- Training: topping, low-stress training, and scrogging spread light.
- Environment: temperature, humidity, and airflow control mold and stress.
How to Estimate Your Harvest Weight
Use dry weight, not wet weight. Wet flower loses 70 to 75 percent of its weight during drying. Weigh after a 7 to 14 day dry and a 2 to 4 week cure.

- Weigh one dried, trimmed bud from the middle of the plant.
- Count the total number of similar buds on the plant.
- Multiply the single bud weight by the bud count.
- Add 10 to 15 percent if the plant had dense top colas.
- Record the final dry weight after cure for your next grow.
Why Per-Plant Yield Numbers Mislead
Growers often quote wet weight or per plant from a sea of green, where each plant is tiny. A 4-ounce plant in a 4x4 tent is not better than four 1-ounce plants in the same space if total yield is equal. Track grams per square foot or grams per watt instead. For legal home grows, plant count limits often make per-plant yield the number that matters, so train each plant to fill its space before flower.
