A hydroponic EC meter is a long cylinder with a sensor on the end which reads how strong your nutrient solution is. The tube has calibrated scales built-in on the sides. A red bulb lights up so you can easily catch the reading.

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 does EC mean in hydroponics?
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 EC meter used for in hydroponics?
Measuring this tells you how much nutrient there is in the water. 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 does a EC meter measure?
Electrical conductivity (EC) is a measure of total soluble and dissolved salts in solution. EC is measured in units of electrical charge. Dissolved nutrients and non-essential ions such as sodium and chloride all contribute to the EC.
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 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.
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].
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.
How accurate are EC meters?
3 in 1 function – This meter can test TDS，EC and temperature in water. Its measuring range of TDS is 0-9999 ppm ± 2%, the EC range 0-9999 μs/cm ± 2%, and the temp range is 32-212°F, 0-99°C with accuracy 2% ℃.
How do you measure water EC?
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.
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.
