How to simulate PPFD in vertical farms

      How to simulate the calculation in speos and how to arrange the plant lights to meet the required PPFD?
      When I use speos, I find that I can only calculate lumens with light intensity sensor. Is there a corresponding simulation teaching process for calculating PPFD?

      Hello,

      There is no easy answer to measure photons, but using a radiometric/spectral sensor, you can obtain a value in watts, then from this, knowing time you can find energy and then calculate the number of photons from the energy of a single of photon at a known wavelenght. 

      You can find help to setup a measure in the result at this adress : Making Measures Analysis

      Best regards
