Interesting. I was reading the instruction sheet about tap water having less than 50 ppm of dissolved minerals. It also stated that the minerals from tap water can "over-fertilize" and "burn out" the plants. Depends where you live in the country. With that said, I don't feel that I should go out and buy another gadget to test my city water etc. Bought a bottle of distilled water instead. Going to Home Depot this evening to find some growing media for my first baby Drosera. I want it to live and prosper.
Thank you.
