A easy way that I look up defintions is go to google and type define: (word)
and it gives you the top 10 definitions. I will try to explain myself better in the future.

Ion: salt molecule

folair: spraying of the leaves with nutes

microsemiens: a more acurate way to mearsure tds or ion content then ppm (parts per millionth) that most of the world outside of the United States uses.
