WHAT ARE EXPANDED CLAY PEBBLES? A. Expanded clay pebbles are used in hydroponics as a medium to support the plant. They are chemically inert, do not affect pH and provide excellent drainage. They are made from a special type of clay, which is heated to a high temperature causing it to pop like popcorn. Back To Top • Q. WHAT IS THE BEST WAY TO CALIBRATE A TDS OR EC METER? A. Standard reference solutions are used. The bottles are marked with the conductivity (EC) value in micro Siemens/cm and the corresponding ppm values for sodium chloride (NaCl) and potassium chloride (KCl) solutions, and sometimes for a “442” reference mixture. The conductivity of sodium chloride solutions is close to that of hydroponic mineral nutrients, so a “1000-ppm NaCl” standard is most frequently used when calibrating the mete
