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. Haydn uses a Bluelab dual meter.

What is hydroponics EC?
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 does EC level mean?
The easiest way to measure fertilizer level is to check Electrical Conductivity (EC). EC is the measure of total dissolved salts in a solution, the factor that influences a plant’s ability to absorb water. EC is a meaningful indicator of water quality, soil salinity and fertilizer concentration.
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.
What is pH and EC in hydroponics?
It is surprising to see that PH and EC are most overlooked aspects in hydroponic and organic as well as regular soil gardening. The PH of 7 is considered neutral and that is the PH of water. EC stands for electrical conductivity which measures the potential of any material to conduct electricity.
What is a good EC reading 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 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 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.
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!
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 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 do you read EC levels?
If you want to convert the other way to find out an EC level from a TDS reading, it is a matter of doing things in reverse. All you need to do here is multiply your ppm reading by two, and then divide the result by 1000. It is far better to rely on a meter when it comes to taking readings than converting manually.
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.
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.
What is the relationship between EC and pH?
Lower pH corresponds with higher [H+], while higher pH is associated with lower [H+]. Electrical conductivity (EC) is a measurement of the dissolved material in an aqueous solution, which relates to the ability of the material to conduct electrical current through it.
