Typical productivity ranges for leafy green operations
Yield benchmarks vary with system design, crop variety, and management, but common reference points help set realistic expectations. Stacked vertical farms dramatically increase productivity per floor area compared with open-field production.
Representative yield metrics
- Yield per square foot per year: many commercial vertical farms report 40–200+ kg/m²/year-equivalent depending on tiers and crop
- Harvests per year: leafy greens often allow 8–20 cycles annually depending on target size and turnover speed
- Yield per growth cycle: a tray or bay will produce a predictable weight depending on crop density and cultivar
Factors influencing benchmarks
- Number of tiers: more tiers multiply floor-area productivity but require sufficient light and airflow
- Crop density and variety: compact cultivars increase per-area pounds
- Light and nutrient optimization: higher DLI and tuned nutrient recipes improve biomass accumulation
- Operational efficiency: minimized losses from pests, disease, and handling increase realized yields
Example benchmarks by crop type
- Microgreens: high value with short cycles—harvests every 7–21 days, high grams per tray
- Baby leaf mixes: frequent harvests, rapid turnover, and consistent demand
- Full-head lettuce: fewer cycles per year but larger weight per plant
How to use benchmarks
- Start with conservative local pilot yields to estimate operating economics
- Track your actual yield per tray and extrapolate to per-square-meter and annual figures
- Use energy per kg and labor per kg as complementary KPIs for economic assessment
Benchmarks provide directional guidance, but each farm’s performance depends on cultivar choice, system design, and management discipline. Measuring and iterating locally is the most reliable path to improving yields.
