Daily light integral (DLI) is the amount of PAR received each day. It is expressed as moles of light (mol) per square meter (m2) per day(d1), or: mol/m 2d .

In greenhouses or growth chambers, DLI values are typically much lower, which can affect the shoot/root ratio, morphology, and the timing of flowering.
