7 Feb 2021 So far they all look great between 400 and 500 ppm in just a few weeks EC to ppm Conversion Chart It is important to note that all ppm (TDS,

EC Values for Hydroponics and Soil by Week Measure the pH level If you choose to measure by PPM, hydro growers should begin with a solution that has 500 PPM and increase by 50 every week. The pH should be close to 5.5, and at least 5.2. Percent to ppm converter How to convert ppm to percent. 1% = 1/100. 1ppm = 1/1000000. So. 1ppm = 0.0001%.

Average the conversion factors. The more data USA 1 ms/cm (EC 1.0 or CF 10) = 500 ppm European 1 ms/cm (EC 1.0 or CF 10) = 640 ppm Australian 1 ms/cm (EC 1.0 or CF 10) = 700 ppm For example, Hanna, Milwaukee 1 ms/cm (EC 1.0 or CF 10) = 500 ppm Eutech 1 ms/cm (EC 1.0 or CF 10) = 640 ppm Truncheon 1 ms/cm (EC 1.0 or CF 10) = 700 ppm Be sure to read the manufacturers specs sheet re the ppm converter.
