Seed Depth 2X Rule Lookup
Illustrative twice-diameter planting-depth heuristic only; species/light/germination requirements override it.
Description
Calculate the illustrative seed-depth heuristic of twice the measured diameter.
Planting seed at twice its diameter is a simple dimensional heuristic. This calculator returns that nominal depth without deciding whether the heuristic suits a species or medium.
When to use this tool
Calculate the illustrative seed-depth heuristic of twice the measured diameter. Use it when the input measurements and conventions below match the operation you need.
- Prepare seedDiameterMm, respecting the measurement basis and boundaries below.
- Compare the worked example with your intended operation before reusing its result.
How to use the tool and how it works
- Enter every field in the input table using the stated units and exact supported selector spelling where applicable.
- Run the tool. Correct input errors before interpreting an output.
- Read the result fields below; use accompanying flags and the stated sign, boundary or model convention when interpreting a number.
seedDiameterMm must be positive. heuristicDepthMm equals twice the supplied diameter.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| seedDiameterMm | Seed diameter mm. Millimeters. | Finite number; greater than zero |
| Output field | Interpretation |
|---|---|
| result | Object containing the following named result fields. |
| result.heuristicDepthMm | Heuristic depth mm; use the stated units and sign convention. |

}Limitations and assumptions
- Light-sensitive seeds, irregular shapes, substrate and growing conditions can require other methods. The tool does not select a species-specific planting recommendation.
- Every declared field is required and unexpected fields are rejected. Numeric inputs must be finite; input errors are distinct from a valid false result or an explicitly qualified output.
- Extremely large inputs and nonfinite or excessively large outputs are rejected. List positions reported by the tool use zero-based indices unless stated otherwise.
Alternative or Complementary methods
Match the supplied measurements and reference context to the actual crop, material and site. A dimensional calculation or retrieved record is not a substitute for inspecting plant condition and applicable product instructions. Compare the scope of the nearby tools below before substituting one.
