Weighted McCree action spectrum and photosynthetic photon flux density (PPFD; µmol.m-2.s-1) from under a Heliospectra E602G light using the Spectrum Genius Essence Lighting Passport light sensor and associated Spectrum Genius Agricultural Lighting app (AsenseTek Inc., Taiwan). (1) Centre measurement at 12 noon on a clear, sunny day, (2) Centre measurement at 12 noon on an overcast day and, (3) Centre measurement at night; a, bench level (155 cm from light) and b, approximate wheat spike height (95 cm from light). Figures were exported from the software.
