Conversion chart

EC, TDS and CF in hydroponics:

EC is an indication of how much resistance is in the solution. The more nutrients in the solution, the higher the EC. EC is often converted into PPM (parts per million), which is only an indication of TDS. CF is simply the European standard of measurement. An EC measurement is simply multiplied by 10 to reach the same CF. However, because the standards differ slightly, they use different conversion factors to reach TDS. For ease of use as well as accuracy, PPM is commonly used in hydroponic cultivation, however, it is an EC parameter that has been multiplied by a conversion factor. Usually, the EC meter will do the conversion automatically, however, some meters may only show EC. You then need to find out which conversion factor applies to that meter and apply it.

Plants require increasing amounts of nutrients as they grow, but will decay if the solution is too strong. It is always recommended to monitor the plant for signs of nutrient deficiency or nutrient burn and adjust the feeds accordingly.

Nice to get a meter with all 3 readings. I'm from America so its very useful
