EC stands for electrical conductivity, which is the potential of any material to conduct electricity. Although most growers are used to measuring the amount of feed that they give in ounces per gallon, grams per litre, or some other unit of measurement, EC goes a little further than this.

What should the EC be for hydroponics?
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.
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.
What is good EC in water?
Ocean waters have water electrical conductivity of about 5 mS, tap water has EC in the range of 50 to 800 uS, depending on the source, freshwater streams may fall in the range of 100 to 2000 uS and distilled water has EC of between 0.5 and 3 uS.
What happens if EC is too high?
Excessively high EC levels lead to stunted growth, leaf damage and eventually plant death.
Is EC the same as pH?
Basics of using pH and EC meters pH refers to the acidity-basicity of a solution, which influences the solubility and availability of nutrients for plant uptake. Electrical conductivity (EC) is a measure of total soluble and dissolved salts in solution. EC is measured in units of electrical charge.
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.
Is TDS same as EC?
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 calculate EC?
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.
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 important is EC hydroponics?
In hydroponics, EC is the measurement of electrical conductivity within your nutrient solution. (It may also be shown as CF, for conductivity factor.) So whilst checking pH levels gives a good indicator of the balance of your available nutrients, EC gives you an idea of the quantity of available nutrients.
Does pH down Increase EC?
pH goes up, EC goes down = Plants are feeding. Potentially raise nutrient levels. pH goes down, EC goes up = Plants are putting nutrient into the water rather than taking them out. The reason this is ideal is that the plants are able to take up specific nutrients more efficiently at different pH levels.
How do you get EC from water?
The value of water EC can be obtained with an electrical conductivity (EC) meter. Typically, the meter probe has two electrodes that are placed in the water sample solution to measure the conductance of electricity between them.
How does EC affect plant growth?
In general, higher EC hinders nutrient uptake by increasing the osmotic pressure of the nutrient solution, wastes nutrients, and the increases discharged of nutrients into the environment, resulting in environmental pollution. Lower EC may severely affect plant health and yield [2, 9].
