Light: Difference between revisions

The amount of light energy (photons) a plant is receiving every 24 hours. For example, if you used a light with a PPFD of 500μmol/m^2/s on a 20/4 lighting schedule that would result in a DLI of 43.20.

DLI is useful as a metric as it takes light schedule into account

Full light intensity from the sun in summer reaches around 60 DLI<ref>https://www.youtube.com/watch?v=ID9rE5JewVg&t=1170s&ab_channel=ApogeeInstrumentsInc. - Bruce Bugee Grow lighting myths</ref>
