Is PPFD measured per plant OR per sqaure meter for the total number of plants within that meter measurement?
In example:
Let's say I'm aiming for 200 PPFD and I'm using the Photone app on my phone to measure PPFD, do I take the reading from the center of the plant (adjusting the light to output 200 ppfd centerpoint if necessary)
OR
Do I measure each corner of the square meter (with each corner needing to read at about 50 ppfd to total up to 200 ppfd)?
