WebDec 15, 2014 · The quality of many plants grown under a daily light integral (DLI; cumulative measure of light intensity during a 24-hour period) of less than 10 mol/m 2 d is significantly reduced. For example, Figure 1 shows the DLI in the Michigan State University research greenhouses without supplemental lighting during one winter.
WebDaily Light Integral or DLI is the total amount of photons in the PAR (400-700 nm) range that land on a target point over the course of a day. Meeting proper DLI requirements has a big impact on a plant’s root and flower development. Different types of plants require different DLI levels and have different photoperiods so check out some ...
