tap water at about 130ppm
Would anyone know if tap water at about 130ppm could be used with general hydroponics (micro, grow, bloom) without harming my plants? Just wondering if 130ppm is considered high for tap water too? Thanx. Mark

130 is about right for tap water. My well water is 250 PPM. If your water has a lot of chlorine you can let it sit in a open bucket for 24 hours to let it evaporate before use.
