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.

Do you need EC meter for hydroponics?
So if you want to be successful with hydroponic crops, it is not absolutely vital for you to have a pH or an EC meter, you just need to follow some simple guidelines to have a wonderful hydroponic crop. 1. Have one gallon of nutrient solution per plant. A one gallon per plant rule of thumb seems to be the best choice.
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 EC meter hydroponics?
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.
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.
What happens if EC is too high?
Excessively high EC levels lead to stunted growth, leaf damage and eventually plant death.
Do I need a pH meter for hydroponics?
A hydroponics or nutrient pH tester is the same thing as a soil device – except you test your nutrient solution or hydroponic reservoir with it. These are very important, and should be used prior to every watering or feeding – unless you know for certain what your water pH is and you aren’t adding nutrients.
What EC is tap 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. EC is relative to temperature.
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.
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.
Does ppm matter in hydroponics?
For a clear picture of how much nutrients your plants are getting, you need to measure the PPM or EC of both your nutrient solution/reservoir (if you’re using hydroponics) and your runoff. If your PPM/EC readings are super low in your runoff, it’s a sign you need to up your nutrients.
How does high EC affect plants?
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 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.
What pH should my hydroponic water be?
With some exceptions, the optimal pH range for hydroponically grown crops is generally between 5.5 and 6.
