Description
Sum capturedByLevel for retainedTotal and return unaccounted=supply-returnFlow-retainedTotal.
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.
Sum capturedByLevel for retainedTotal and return unaccounted=supply-returnFlow-retainedTotal.
When to use this tool
Use Stacked Tray Irrigation Per Level Balance 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 supply, capturedByLevel, returnFlow. Keep parallel arrays aligned. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read retainedTotal, unaccounted. Use the output convention below.
Sum capturedByLevel for retainedTotal and return unaccounted=supply-returnFlow-retainedTotal. Require nonnegative supply, return flow, and level quantities.1

}Limitations and assumptions
- All entries need the same volume or flow-rate basis and period. Return and retained quantities can exceed supply, producing a negative residual; the tool does not model irrigation hydraulics or locate losses.
- 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.
