General definition:
PPFD represents the quantum number of light in the visible wavelength range per unit time area, and its unit is μmol/m2s.
PPFD also indicates the correlation between the number of photons and photosynthesis.
In SGAL, you can not only confirm the value of all visible PPFD, but also compare the values ​​in different ranges, and confirm the different ranges of data when adjusting the lamps. (UV 380 ~ 399 nm, blue 400 ~ 499 nm, green 500 ~ 599 nm, red 600 ~ 700 nm, near infrared 701 ~ 780 nm)
