remended light intensity levels for crusher plants

Oct 30, 2019 It is a function of photosynthetic light intensity and duration (day length) and is usually expressed as moles of light (mol photons) per square meter (m −2) per day (d −1 ), or: mol m −2 d −1. DLI is usually calculated by measuring the photosynthetic photon flux density (PPFD) in μmol m −2 s −1 (number of photons in the PAR ...

    Light in the Greenhouse How much is Enough Cropking

    Nov 16, 2006 As plants grow and increase the number of leaves, the need for light increases. Part of this is probably a result of the newer leaves on the plant tending to shade the older leaves at the lower levels. Providing higher light intensity as the plant grows ensures that more light will reach some of the older leaves on the plant.
