Plants Module

The plants module expects reflectance spectra. V0 metrics are intentionally simple proxies:

• ndvi_like
• red-edge position
• R750/R700 chlorophyll proxy
• PRI-like R531/R570
• stress score

from lux.modules.plants import plant_metrics

metrics = plant_metrics(reflectance_spectrum)

Calibration Work Needed

Pair field spectra with leaf state labels, watering history, disease pressure, SPAD/chlorophyll references, and camera notes. The visible/NIR module can track relative changes well, but absolute agronomy claims need local calibration.
