Fortunately, this is an easy test to do yourself! Some plants have a sensitivity to it, and some prefer to have it to germinate.

The best way to test fluoridated vs. non is to do comparisons side by side. Many seedlings will prefer non-fluoridated water, but many mature plants will need it, at least, occasionally to prevent chlorine and fluorine deficiencies.
