Daily Light Integral Dli And Greenhouse Daily light integral (dli) is the amount of par received each day as a function of light intensity (instantaneous light: μmol·m 2·s 1) and duration (day). it is expressed as moles of light (mol) per square meter (m 2) per day. (d 1), or: mol·m 2·d 1 (moles per day). the dli concept is like a rain gauge. just as a rain gauge collects the. Daily light integral (dli) is a measure of the aggregate amount of par light that a surface receives over the course of a day. it is a very useful metric to determine if a particular location receives sufficient amounts of light for plants to grow well. low light plants require between 5 10, medium light plants 10 15, and high light plants will.

How To Measure And Calculate Supplemental Light In A Greenhouse Or Where ppfd expresses light intensity in a second, dli expresses the sum of those measurements in a 24 hour period (86,400 seconds per 24 hours). dli is written as mol m−2d−1 (moles of light (mol photons) per square meter (m−2) per day (d−1)) dli is the sum of ppfd in a day. heavily influences short day plants (the plant, chrysanthemum. Measuring daily light integral (dli) the daily light integral (dli) concept measures the total amount of photosynthetic light plants receive during the day — not just the intensity of sunlight at a given moment. conceptually, dli is similar to how we measure rainfall. to measure dli, we “collect” light throughout the day similar to a rain. You may calculate the dli (daily light integral) value by following the steps given below: multiply the ppfd (photosynthetic photon flux density) by the daily light hours. multiply the result by 3600. divide the result from step 2 by 1000000. the result is the dli value as mol m² day. Dli is an important variable to measure in every. greenhouse because it in uences plant growth, de . velopment, yield, and quality. for example, dli can. in uence the root and shoot growth of.

Divide the above figure by 10^6 to convert it from micromoles per day to moles per day (using a calculator, enter 10, then press the xy button, then enter 6) this will be your dli. for example, let’s say we have a ppfd of 400μmol m 2 s 1 and we leave our lights on 14 hours a day. 400 * 60 = 24,000. 24,000 * 60 = 1,440,000.
