![]() ![]() ![]() So what’s all of this actually mean? Well, outside of pH (which we explain in detail here), all of the other parameters listed above - to include TDS, EC, PPM, and cF - are essentially different scales measuring the same thing (similar to how Celsius and Fahrenheit are both measurements for temperature).Īre they technically different? Yes. cF (Conductivity Factor): Measures electrically charged nutrient ions in your nutrient solution.PPM (Parts Per Million): Measures the concentration of elements in your nutrient solution.EC (Electrical Conductivity): Measures how well a liquid can carry a current through it.TDS (Totally Dissolved Solids): Refers to the amount of substances - such as salts, minerals, metals, etc - that have been dissolved in water.pH (Potential for Hydrogen): Measure of how acidic or basic water is using a 14 point scale.There are 5 “measurement terms” that you’ll likely encounter when researching how to grow your plants - pH, TDS, EC, cF, and PPM. ![]() If you’re new to hydroponics and would like to learn more, try reading our “ What is Hydroponics” guide or try exploring our Hydroponics Hobby Center for all the latest and greatest information! These charts, which contain a broad range of values, should give you a ballpark estimate of what’s needed for each of your plants. With that in mind, we’ve created a few charts and tables that outline each parameter - pH, EC, cF, and PPM - to get you started. But unless you’re an experienced grower, you’re unlikely to know what these ranges are. Please read Disclaimer for more information.Īs you start your hydroponic journey, you’ll probably hear a lot about certain parameters - such as pH and EC - and “measurement ranges” that your plants need to stay in.
