EC is a measure of the salts in your system—that is, the level of nutrients in your system. EC should be kept between 1.2 and 2.0.

What is EC levels in water?
EC or Electrical Conductivity of water is its ability to conduct an electric current. Salts or other chemicals that dissolve in water can break down into positively and negatively charged ions. These free ions in the water conduct electricity, so the water electrical conductivity depends on the concentration of ions.
Is EC and ppm the same?
Summary. ppm stands for parts per million & is the most common domestically used unit when measuring TDS. EC stands for electrical conductivity, which is a measurement of the ability of something to conduct electricity. In horticulture, EC is the most accurate way to measure nutrient concentration in solution.
How do you control EC in hydroponics?
To reduce the EC value, clean water is added to the water tank. To increase the EC value, nutrients are added to the water tank. If the EC value of water rises during time, it is a sign that plants are unable to use nutrients in water. This may be due to the wrong nutrients or wrong pH value of the water.
Is TDS and EC the same?
Total Dissolved Solids (TDS) and Electrical Conductivity (EC) are two separate parameters. TDS, in layman’s terms, is the combined total of solids dissolved in water. EC is the ability of something to conduct electricity (in this case, water’s ability to conduct electricity).
How do you test for EC levels?
To measure soil water EC, water is extracted from a lysimeter, well, or piezometer and measured. Alternately, a probe attached to a meter can be lowered into a well or piezometer and the liquid EC can be measured in that manner.
What happens if EC is too high?
Excessively high EC levels lead to stunted growth, leaf damage and eventually plant death.
Can you convert TDS to EC?
How do I convert between TDS and EC readings? To obtain an approximate sodium chloride TDS value, multiply the EC reading (in milliSiemens/cm) by 1000 and divide by 2. To get an EC value, multiply the ppm reading by 2 and divide by 1000.
What is a good EC for soil?
Optimal EC levels in the soil therefore range from 110-570 milliSiemens per meter (mS/m). Too low EC levels indicate low available nutrients, and too high EC levels indicate an excess of nutrients.
What is the ideal EC for hydroponics?
For most hydroponic crops, the ideal range of EC for most crops is between 1.5 and 2.5 dS/m. A higher EC could prevent the plant from absorbing nutrients due to increased (more negative) osmotic pressure, and EC levels that are too low could adversely impact yield.
What should the EC be for hydroponics in US CM?
Typical EC values for hydroponic nutrient solutions can range from 500 to 2000 µS/cm, or 0.5 to 2 mS/cm. TDS measurements can be expressed in units of parts per million (ppm) or parts per thousand (ppt).
How do you test for EC in hydroponics?
How to measure EC? The easiest way is by using a digital meter, such as the Bluelab CF Truncheon. These work by measuring the electrical conductivity via the electrodes on the bottom of the meter. All you need to do is dip the end into your solution and check the digital reading.
How do I convert EC to TDS?
In order to determine the actual TDS value, you must multiply the EC value by 1000 and divide that number by 2. To calculate the EC value, multiply the ppm value by 2 and divide by 1000. Water quality variables such as conductivity (EC) and total dissolved solids (TDS) can be used to calculate salt concentration.
What does a TDS EC meter do?
An electrical conductivity (EC) or TDS meter is a quick method to estimate TDS. Water conducts electricity, but the dissolved minerals (ions) in water are what actually conduct the electricity.
