WHAT DOES A TDS OR EC METER MEASURE?
A. The electrical conductivity (EC) of your nutrient results from motion of mineral ions when the meter applies an electrical voltage. The ppM value of a sodium chloride solution happens to be very close to half of its conductivity value (in microSiemens/cm), so many meters display the conductivity as an equivalent NaCl amount Back To Top • Q. HOW DO I CONVERT BETWEEN TDS AND EC READINGS? A. To obtain an approximate sodium chloride TDS value, multiply the EC reading (in micro Siemens/cm) by 1000 and divide by 2. To get an EC value, multiply the ppm reading by 2 and divide by 1000. Thus, if your EC is 1: 1*1000/2= 500 ppm. And if your ppm is 500: 500*2/1000= 1 EC Back To Top • Q. HOW DOES THE TASTE OF HYDRPONIC PRODUCE COMPARE WITH SOIL GROWN PRODUCE? A. Hydroponic produce frequently exceeds soil grown produce in terms of flavor and nutrition. This is because all of the nutrients required by the plant are immediately available when the plant needs them. Back To Top • Q. WHY IS GROWING H
