How Much Cannabis Can You Yield?
Cannabis yield depends on four main factors: grow space size, lighting, genetics, and grower experience. Indoor growers using LED lights typically harvest 0.5 to 1.0 ounces per square foot, while HPS setups can push 0.75 to 1.25 oz/sq ft. Outdoor plants have the highest potential — a single plant in open ground can produce 1 to 5+ ounces depending on climate and strain.
Our yield calculator uses these baseline ranges and adjusts for your experience level and seed type. Autoflowering cannabis seeds allow more harvest cycles per year (up to 4 indoors), while feminized photoperiod strains typically produce larger individual harvests.
Cannabis Yield Per Square Foot — What to Expect
| Light Type | Yield / sq ft | Best For |
|---|---|---|
| LED | 0.5–1.0 oz | Energy efficiency, full spectrum |
| HPS | 0.75–1.25 oz | Maximum intensity, proven results |
| CFL | 0.25–0.5 oz | Small spaces, supplemental |
| Sunlight (Outdoor) | 0.75–2.0 oz | Highest potential per plant |
These ranges represent realistic expectations for properly maintained grows. Factors like nutrient management, VPD control, and plant training can push you toward the higher end.
How to Increase Cannabis Yields
Choose High-Yield Genetics
Strain selection is the #1 factor. Some strains are bred specifically for heavy harvests.

LST, topping, and ScrOG can increase yields 20-40% by maximizing light exposure.

More light = more yield (to a point). LED and HPS both deliver strong results.

Proper feeding through each stage prevents deficiencies and maximizes bud development.

The right genetics make the biggest difference. These strains consistently produce above-average harvests when given proper care. Whether you grow autoflowering seeds for faster cycles or feminized photoperiod seeds for maximum single-harvest weight, choosing yield-oriented genetics is your foundation.
Indoor vs Outdoor Yield Comparison
💡 Indoor Growing
- • Typical: 0.5–1.25 oz per sq ft
- • 2–4 harvests per year
- • Full control over environment
- • Year-round growing
- • Higher startup cost, lower risk
☀️ Outdoor Growing
- • Typical: 1–5+ oz per plant
- • 1 harvest per year (fall)
- • Free sunlight, lower costs
- • Larger plants possible
- • Weather and pest risks
How Accurate Is This Cannabis Yield Calculator?
Our calculator provides realistic yield ranges based on established growing data — not inflated marketing numbers. The estimates account for grow space, lighting efficiency, seed genetics, and grower experience. However, actual harvests depend on many variables including nutrient management, environmental control, training techniques, and strain-specific characteristics.
We deliberately show conservative ranges. Beginners should expect results closer to the lower end, while experienced growers using high-yield cannabis seeds with proper training can consistently hit or exceed the upper range. The “optimized” number represents what skilled growers achieve with premium genetics, optimized lighting, and dialed-in environments.
This calculator is based on real grow data and industry-standard yield ranges used by indoor and outdoor cultivators across the United States. The logic reflects what 200,000+ American growers have reported when using seeds from Royal King Seeds.
Use these estimates as a planning starting point. Your actual results will improve with each grow cycle as you learn your specific environment. For the most accurate projections, factor in your strain's genetic potential, your lighting setup, and whether you use plant training techniques.
Frequently Asked Questions
How much weed can I grow in a 4x4 tent?
A 4x4 tent (16 sq ft) with LED lighting typically yields 8–16 ounces per harvest for an intermediate grower. Beginners can expect 6–12 ounces. Using high-yield genetics and training techniques can push you toward the upper range.
How many plants per square foot for cannabis?
For autoflowers, plan 1–2 plants per square foot. For feminized photoperiod plants with training, 1 plant per square foot is standard. In a 4x4 tent, most growers run 4–9 plants depending on pot size and training method.
Cannabis yield LED vs HPS — which is better?
Modern LEDs match or exceed HPS yields while using 30–40% less electricity. HPS delivers 0.75–1.25 oz/sq ft while quality LEDs deliver 0.5–1.0 oz/sq ft. The gap has closed significantly, and LED advantages in heat management and spectrum control make them the preferred choice for most growers.
How much does an outdoor cannabis plant yield?
A single outdoor cannabis plant can yield 1–5+ ounces depending on strain, climate, and growing season length. In warm climates with long seasons (California, Southern states), plants can reach massive sizes. High-yield outdoor strains like Big Bud and Critical Mass are bred for heavy harvests.
How do autoflower yields compare to feminized?
Individual autoflower plants yield less than feminized photoperiod plants (typically 1–4 oz vs 2–8 oz per plant). However, autoflowers complete in 8–10 weeks and allow 3–4 harvests per year indoors, often matching or exceeding annual yields from photoperiod plants.
