DLI Target Crop Lookup

Audit measured photon dose against exact caller crop-stage DLI policy; no fabricated universal crop targets, light integration or growth/yield guarantee.

Description

Daily light integral describes accumulated photon exposure.

Daily light integral describes accumulated photon exposure. A crop-stage target must be supplied independently to interpret the dose.^[1]

Enter aligned nonempty unique stage IDs/nonnegative bounds, exact query and nonnegative measured DLI. Validate the selected ordered band; return range, signed margin and inclusive gate.

When to use DLI Target Crop Lookup

Use DLI Target Crop Lookup when you need to evaluate the supplied records under the calculation and evidence rules below. No light integration, universal crop target or growth/yield guarantee is supplied.

Prepare the measured crop, container, lighting or inventory records requested. Supply verified local catalogs, calibration factors and crop-stage limits; keep units and dates consistent.

How to use DLI Target Crop Lookup and understand its results

Prepare the measured crop, container, lighting or inventory records requested. Supply verified local catalogs, calibration factors and crop-stage limits; keep units and dates consistent.
Enter callerCropStageIds, callerMinimumDli, callerMaximumDli, queryCropStageId, measuredDli using the field table and calculation rules, then run the tool.
Read callerDliTargetRange, signedObservedDliBandMargin, withinCallerCropStageBand. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
callerCropStageIds	Caller crop stage ids	list of string	Required
callerMinimumDli	Caller minimum dli	list of number	Required
callerMaximumDli	Caller maximum dli	list of number	Required
queryCropStageId	Query crop stage id	string	Required
measuredDli	Measured dli	number	Required

Enter aligned nonempty unique stage IDs/nonnegative bounds, exact query and nonnegative measured DLI. Validate the selected ordered band; return range, signed margin and inclusive gate.

margin=min(measuredDLI−minimum,maximum−measuredDLI)

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
callerDliTargetRange	Caller dli target range	list of number
signedObservedDliBandMargin	Signed observed dli band margin	number
withinCallerCropStageBand	Within caller crop stage band	boolean

Limitations and assumptions

No light integration, universal crop target or growth/yield guarantee is supplied.

Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Extremely large text inputs are rejected. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors. A successfully returned false flag is an evaluated outcome; its meaning is explained above.

Alternative or Complementary methods

Use Lux to PPFD Converter: Lux describes human-vision illuminance, while PPFD describes photon flux per area. Matched spectral calibration is needed to relate them. For a complementary task, use Germination Mat Temp Range Lookup: Root-zone temperature observations can be weighted by represented duration. An exact crop-stage catalog defines the local acceptable band.
