When fertilizing, what's the difference between ppm and g/L??
I have a really dumb question about fertilizing here... What is the link/difference between ppm and grams per liter?? Somehow I know that the answer will be very obvious once I hear it....
In France it seems like g/L is the preferred (and nearly only) measure. We always speak about fertilizer in g/L.
I get a little lost in the threads sometimes when you speak of feeding your orchids!! Anyone care to enlighten me?
