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.
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 does EC mean in growing plants?
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. In horticultural applications, monitoring salinity helps manage the effects of soluble salts on plant growth.
Why EC is important?
EC stands for Electric Conductivity. Simply put, the EC value is the salt concentration in your substrate or nutrient solution. The salt concentration is a good indication of the available nutrients. This is why the EC value is important: it tells you if your plants are receiving the right amount of nutrients.
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 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 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.
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 High EC good in soil?
In soil, electrical conductivity (EC) is a measure of the ability of the soil to conduct an electrical current. 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 a good EC for plants?
For most plants you want the EC measurement to be hitting between 1.2-1.6 during the vegetative stage and 1.6-2.4 during flowering, but this can be dependent on the type of plant that’s growing.
What causes EC to rise?
Our account balance (media-EC) is made up of deposits and withdrawals. The deposits are made with salts contained in the irrigation water, with water-soluble fertilizer, or by slowly soluble or controlled-release nutrients. The account balance (media-EC) increases when deposits are greater than withdrawals.
What is EC meter used for?
An electrical conductivity meter (EC meter) measures the electrical conductivity in a solution. It has multiple applications in research and engineering, with common usage in hydroponics, aquaculture, aquaponics, and freshwater systems to monitor the amount of nutrients, salts or impurities in the water.
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!
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].
