Cutting Stick Spacing Per Tray Calculator

Plan actual rectangular cutting envelopes with gaps only between occupied positions and explicit usable tray dimensions; no rooting/crowding recommendation or cell-count table.

Description

Rectangular cutting positions require room for their envelopes and intervening gaps.

Rectangular cutting positions require room for their envelopes and intervening gaps. Exterior gaps are not added in this model.^[1]

Enter nonnegative usable width/length/gap and positive cutting dimensions in cm. Bound each axis count to 0–1,000,000 and product to safe integer; return counts, positions and unused outer dimensions.

When to use Cutting Stick Spacing Per Tray Calculator

Use Cutting Stick Spacing Per Tray Calculator when you need to evaluate the supplied records under the calculation and evidence rules below. No rooting-space recommendation, rotated packing or tray-cell catalog 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 Cutting Stick Spacing Per Tray Calculator 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 usableTrayWidthCm, usableTrayLengthCm, callerCuttingWidthCm, callerCuttingLengthCm, callerCuttingGapCm using the field table and calculation rules, then run the tool.
Read cuttingColumns, cuttingRows, plannedWholeCuttingPositions, unusedOuterWidthCm, unusedOuterLengthCm. 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
usableTrayWidthCm	Usable tray width cm	number	Required
usableTrayLengthCm	Usable tray length cm	number	Required
callerCuttingWidthCm	Caller cutting width cm	number	Required
callerCuttingLengthCm	Caller cutting length cm	number	Required
callerCuttingGapCm	Caller cutting gap cm	number	Required

axisCount=floor((usable+gap)/(item+gap)); used=count×item+(count−1)gap when count>0

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

Output field	Meaning	Value type
cuttingColumns	Cutting columns	number
cuttingRows	Cutting rows	number
plannedWholeCuttingPositions	Planned whole cutting positions	number
unusedOuterWidthCm	Unused outer width cm	number
unusedOuterLengthCm	Unused outer length cm	number

Limitations and assumptions

No rooting-space recommendation, rotated packing or tray-cell catalog is supplied.

Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Plug Tray Cell Count Lookup: A tray catalog can distinguish nominal grid positions from structurally unusable cells. Neither count establishes germination or filled-cell inventory. For a complementary task, use Quonset Overwinter Plant Count Calculator: Overwinter capacity depends on independently allocated container space. Existing stock and reserved empty positions both consume that budget.
