Description
Calculate tray-cell occupancy and empty cell count.
Vertical-farm records distinguish nominal growing area from floor footprint, occupied cells from healthy seedlings, and supplied lighting power from photon flux. Energy accumulates power over time, while flux per area is an instantaneous spatial basis. Counts, runtime readings and water shares need consistent periods and references before they can describe a real facility.
Calculate tray-cell occupancy and empty cell count.
When to use this tool
Use Grow Tray Occupied Cell Share when you already have occupiedCells, totalCells and need to calculate tray-cell occupancy and empty cell count.
How to use the tool and how it works
- Enter occupiedCells, totalCells. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read occupiedFraction, emptyCells. Use the output convention below.
Require safe whole totalCells>=1 and occupiedCells in [0,total]; return occupied/total and total-occupied.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| occupiedCells | Occupied Cells | Required. Safe integer; minimum 0. |
| totalCells | Total Cells | Required. Safe integer; minimum 1. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| occupiedFraction | Occupied Fraction | Required. Finite number. |
| emptyCells | Empty Cells | Required. Safe integer. |

}Limitations and assumptions
- Cell occupancy is caller supplied; it does not measure germination, plant health or productive capacity.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- 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. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use measured fixture input and runtime logs for energy, a spatially sampled light map for illumination, and verified tray inventories for occupancy. Reconcile volumes and reference periods before extending one local share to a whole facility.
