High Yielding Cannabis Strains Per Plant: Yield Guide

High Yielding Cannabis Strains Per Plant

Answer first: a photoperiod cannabis plant grown indoors yields 60 to 150 grams of dried flower. An outdoor plant in the ground or in a 50 gallon pot yields 300 to 1000 grams. Autoflower plants yield 40 to 150 grams indoors. Genetics set the ceiling. Light, root volume, and veg time decide how close you get to it.

What Per Plant Yield Means

Per plant yield is dried, trimmed flower, weighed after a 10 to 14 day dry and a 2 week cure. Wet weight runs 4 to 5 times higher. A plant that weighs 400 g wet gives about 90 g dry. Growers who say 1 pound per plant mean 454 g dry.

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

Yield Ranges by Grow Type

• Indoor photoperiod, 5 gallon pot, 4 weeks veg, 600 W light: 60 to 110 g per plant
• Indoor photoperiod, 8 weeks veg, SCROG screen, 600 W light: 120 to 200 g per plant
• Indoor autoflower, 3 gallon pot, 18/6 light: 40 to 90 g per plant
• Outdoor photoperiod, 30 gallon pot, full sun: 250 to 500 g per plant
• Outdoor photoperiod, in ground, 6 month season: 500 to 1000 g per plant

1 gram per watt is the standard indoor target. A 600 W lamp over a 1.2 m by 1.2 m tent covers 4 to 6 plants. That is 100 to 150 g per plant when the canopy fills with no gaps.

Strains With High Per Plant Yields

Photoperiod, Indoor

• Northern Lights: 90 to 150 g per plant. 7 to 9 week flower.
• Big Bud: 150 to 200 g per plant in a 7 gallon pot. 8 to 9 week flower.
• Critical Kush: 100 to 150 g per plant. 8 week flower.
• Gorilla Glue: 90 to 130 g per plant. 8 to 9 week flower.
• White Widow: 80 to 120 g per plant. 8 to 9 week flower.

Photoperiod, Outdoor

• Blue Dream: 400 to 700 g per plant in a long season. 9 to 10 week flower.
• Sour Diesel: 300 to 500 g per plant. 10 to 11 week flower.
• Jack Herer: 300 to 500 g per plant. 9 to 10 week flower.
• Amnesia Haze: 500 to 800 g per plant in warm climates. 11 to 13 week flower.

Autoflower

• Northern Lights Auto: 60 to 110 g per plant. 70 to 80 days seed to harvest.
• Critical Auto: 80 to 150 g per plant. 70 to 75 days.
• Amnesia Auto: 60 to 120 g per plant. 75 to 85 days.

Autoflower numbers come from the seed banks that sell them. Independent trials are rare. Treat the top of a range as a ceiling, not an average.

What Moves Yield Per Plant

1. Root volume. A 5 gallon pot holds about 3 times the root mass of a 2 gallon pot. Yield tracks pot size up to 10 gallons indoors.
2. Light. Yield scales with PAR, not wattage claims. Target 600 to 900 micromoles per square meter per second in flower.
3. Veg time. Each extra week of veg adds 15 to 25 percent more flower, until the canopy crowds itself.
4. Plant count. 4 plants in a 1.2 m tent beat 1 plant in the same space, because the canopy fills sooner.
5. Training. Topping at node 5 and low stress training produce 8 to 12 colas in place of 1 central cola.
6. Climate. 24 to 28 C and 40 to 50 percent RH in flower. VPD 1.2 to 1.5 kPa.
7. Nutrition. Nitrogen drops after week 3 of flower. Phosphorus and potassium rise.

How to Measure Your Own Numbers

Weigh each plant after trim, not the whole harvest. Log dry weight, pot size, veg days, and light wattage. After 3 runs you have a real per plant average for your room. Breeder yield figures come from the breeder's room, lights, and climate. Those numbers do not transfer.

Legal Note

Plant count limits apply in the US. Check state rules. Some states cap yield per plant by law, not by genetics.
