GrowLux
Measure the spot where leaves live.
Estimate lux from camera exposure metadata, convert it to source-dependent PPFD and DLI, and compare broad plant-light targets. Readings are estimates, not calibrated PAR measurements.
GrowLux’s job
A reading stays connected to its plant space, light-source assumption, photoperiod, uncertainty, and history so the result can be revisited where the leaves actually sit.
GrowLux workflow
- 01
Choose the plant space and the light source in use
- 02
Measure at canopy height with the phone in the stated position
- 03
Inspect the exposure-derived lux estimate and uncertainty
- 04
Convert with the selected source assumption to estimated PPFD and DLI
- 05
Compare broad targets and revisit the same space over time
GrowLux limits
GrowLux provides exposure-derived estimates with source-dependent conversions. It is not a calibrated PAR meter, and its broad plant targets do not guarantee growth or crop outcomes.
