Disclaimer

PlantLightIndex provides horticultural information, measurement tools and evidence-aware practical references. Growing conditions vary by plant, environment and acclimation.

Measurements and estimates

Window-light estimates are broad approximations. Fixture estimates depend on the quality and context of the underlying measurements. Observe actual plant response and measure PPFD at leaf level when possible.

Evidence limits

A practical reference is not a guaranteed optimum, safety threshold or promise of plant performance. Where evidence is limited, PlantLightIndex labels that limitation.
