ideal grow light distance intensity scaling calculator online
Use ideal grow light distance intensity scaling online for old PPFD, old distance m, new distance m. Point-source far-field approximation; LED arrays can behave differently at short distances. Planning estimate using supplied crop, soil or material parameters. Growth, weather and application suitability are not predicted.
How to use it
Enter old PPFD. Set old distance m, new distance m. Select Calculate and check the labeled output. Copy or download the JSON result.
Options and example settings
Calculation method
estimated_PPFD = old_PPFD*(old_distance_m/new_distance_m)^2 (^ means exponentiation; trig functions ending in d use degrees).
Worked examples
Apply ideal grow light distance intensity scaling to the case below, keeping the displayed units and assumptions. Point-source far-field approximation; LED arrays can behave differently at short distances.

}Choose the right tool
Choose spacing tools for layouts and water tools for explicit area, flow and depth. Crop coefficients, soil properties, declared nutrient percentages and application rates must come from suitable local or product-specific information.
Limitations and common mistakes
- Point-source far-field approximation; LED arrays can behave differently at short distances. Planning estimate using supplied crop, soil or material parameters. Growth, weather and application suitability are not predicted.
- Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
