Quick Answer: With Hydroponics What Does Ec Mean?

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 is a good EC for hydroponics?

The two main measurements a hydroponic grower needs to make are pH and EC levels. 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. EC and pH meters are affordable and often come as one dual meter.

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.

What are EC levels in hydroponics?

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 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 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.

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].

Is EC the same as TDS?

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). That’s TDS!

Does pH down raise 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.

Is EC the same as PPM?

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.

What should the EC be for hydroponic tomatoes?

The optimum EC range for tomatoes is 2.0 to 3.5 milliMhos. While EC measures the total dissolved minerals in a solution it does not identify the amounts of specific elements present.

What should be the EC of drinking water?

Generally, the amount of dissolved solids in water determines the electrical conductivity. Electrical conductivity (EC) actually measures the ionic process of a solution that enables it to transmit current. According to WHO standards, EC value should not exceeded 400 μS/cm.
