How much does one autoflower plant yield?

Most autoflowers finish between 1 and 4 ounces (28 to 112 grams) of dried flower indoors. A dialed-in setup with strong light and a big pot can push 4 to 6 ounces. Outdoor plants in a long, sunny season often land in the same range, sometimes higher, but weather and pests widen the spread. Anything above 6 ounces per plant is a good run, not a baseline.

High Yielding Cannabis Strains Per Plant: A Yield Guide

Realistic ranges by setup

Strain size class matters more than most people admit. A compact indica-dominant auto in a 2 gallon pot has a ceiling. A large sativa-leaning auto given root space is playing a different game.

What actually changes the number

Genetics set the ceiling. If the breeder lists 60 to 90 grams per plant under their conditions, you are not pulling 200 grams from that seed without hydro and some luck.

Cannabis Yield Per Plant of High Yielding Strains: What to Expect

Light is the next lever. Autoflowers run on a fixed clock from sprout, so every weak week in veg is gone for good. I aim for 30 to 45 DLI in veg and 40 to 55 in flower, at 18/6 or 20/4. Dim light is the most common reason a plant stalls at an ounce.

Container size decides how big the roots get, and roots decide canopy. Three gallons is the practical floor indoors. Five gallons is where most growers see the jump.

Training should stay light. Low-stress training to open the canopy helps. Topping works on vigorous autos, but it costs recovery time the plant never gets back. Heavy defoliation in early flower is a yield tax.

Environment covers the rest. Root zone at 20 to 24 C (68 to 75 F), humidity around 60 to 70 percent in veg and 40 to 50 percent in flower, plus steady airflow. Heat stress in week three shows up as airy buds in week ten.

Why autos usually yield less than photoperiods

A photoperiod plant can veg for eight weeks or eight months, because you control the clock. An autoflower starts flowering on its own schedule, often around day 21 to 35, whether you are ready or not. That shorter, less flexible vegetation window is the whole tradeoff: you give up potential weight for speed and a tent that does not need to be light-proof.

Setting a target that makes sense

Pick a number based on your pot, your light, and your experience, then track grams per watt or grams per square foot. Comparing your 2 gallon closet plant to a DWC grow with a 700 W bar light tells you nothing useful. Log dry weight, days from sprout to chop, and what went wrong. The second run is where most growers find their extra ounce.
