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 the correct EC 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 is a good EC?
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 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).
What should TDS be for hydroponics?
Ideal TDS Levels for Different Plants in Hydroponics The ideal TDS reading for plants grown hydroponically varies from around 500 or 600 on up to well over 1,000. That said, we suggest sticking with a TDS level of around 800.
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.
How do you fix high EC?
To correct for high EC, irrigate with clear water to the point of excessive leaching to wash out the extra salts. EC that is too low indicates insufficient nutrition (Photo 2). To correct for low EC, apply fertilization.
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 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.
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.
What is the best pH level for hydroponics?
With some exceptions, the optimal pH range for hydroponically grown crops is generally between 5.5 and 6. Many fruits and vegetables, such as melons, apples, beans, squash, and tomatoes prefer that range. Blueberries, on the other hand, need a lower, more acidic pH between 4.0 and 5.0.
How do you adjust TDS on hydroponics?
Plan to add 1 milligram of nutrient per 1 liter of water for each point you wish to increase the PPM. If, for example, the PPM is 800 and you want it to be 1,500, then it needs to be raised by 700 milligrams for each 1 liter of water in your hydroponic system’s reservoir.
Why does hydroponic TDS increase?
So, in a hydroponic nutrient solution, the EC and TDS values have a more direct correlation, due to the high percentage of dissolved salts. Your main objective as a grower is to get an accurate assessment of the concentration of your nutrient solution. Both TDS and EC are viable routes to getting this information.
