pH & PPM Measuring
pH is the measurement of the acidity or alkalinity of the soil or growing medium. A pH of 7 is considered neutral. A pH below 7 is acid and above 7 is alkaline. Most plants want a pH of between 5 and 7 (slightly acid). Eco produces pH-Up and pH-Down to adjust the acid/alkaline balance to be what your plants need. When selecting different plants, you should take the pH into consideration so that all plants in each system have similar pH and PPM requirements. pH adjustments can be made with either liquid or powder. Eco sells both, as well as calibration fluids to guarantee accuracy of test equipment. A wide range of pH measuring equipment is available from ECO.
Rule of thumb for adjusting pH - go slow! Correct the pH a little bit, then measure until you get a feel for which way things are going. If you go too far with pH adjustments, you can really upset your system.
Caution: Do not exceed a pH of 7 - a nutrient lockup can occur depriving your plants of essential elements.
