What is the difference between PPFD and PPF? | …

PPFD can be the result of multiple lamps lighting a single area. PPF, on the other hand, measures the amount of PAR from a single grow light. You can make meaningful comparisons between lamps by comparing its PPF measurement. That being said, be aware that depending on the beam angle, this can affect eventual PPFD readings depending on the products.

Best LED Grow Lights of 2021 Reviewed - LED Lights - Grow ...

Mar 03, 2020 · PPFD (umol/j/m2) and DLI is the correct metric for measuring useful light intensity over a given area. Coupled with the correct spectrum for your plant type and phase of growth, PPFD (and spectrum) are the keys to a successful grow. However, for the purpose of estimation, we will report wattage calculations in this article.
