Description
Return ratio=occupiedArea/trayArea, requiring positive trayArea and occupiedArea from zero through trayArea.
An indoor-growing record or design budget combines quantities such as tray area, operating time, water volume, electrical energy, and light output. Ratios depend on a stated production boundary and period. Supplied conversion factors and idealized geometry need to remain separate from measured equipment and crop performance.
Return ratio=occupiedArea/trayArea, requiring positive trayArea and occupiedArea from zero through trayArea.
When to use this tool
Use Tray Occupancy Area Ratio when you need one stated production, lighting, water, or geometry term from a consistently defined growing-system budget.
How to use the tool and how it works
- Enter occupiedArea, trayArea. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read ratio. Use the output convention below.

| trayArea | Tray Area | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |

| ratio | Dimensionless ratio under compatible input units and the stated formula. | Required. Finite number. |

}Limitations and assumptions
- Both areas must use a common squared unit and reporting basis. The ratio does not infer canopy overlap, crop health, growth, or adequate spacing.
- The field tables state structural bounds; the mechanics also specify cross-field constraints. Malformed inputs and unsupported domains cause errors. A successful false flag, empty branch value, or zero placeholder has the meaning stated above and is distinct from an input error.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Signed zero is exported as zero.
Alternative or Complementary methods
Compare the supplied budget with measured system records and keep the same production boundary. Equipment selection, installation, and crop requirements need an appropriate engineering or agronomic assessment.
