PPM Levels for Cannabis Plants. PPM (Parts per Million) levels is the measure of nutrients in the water used to feed your cannabis plants. There are minerals in the tap water you will use to water your plants and you will be adding some fertilizer solutions to the water which also can be measured in parts per million.

To get an EC value, multiply the ppm reading by 2 and divide by 1000. Thus, if your EC is 1: 1*1000/2= 500 ppm. And if your ppm is 500: 500*2/1000= 1 EC. Is it better to use an EC or a TDS meter? Answer: If you have plant nutrient recommendations in EC units, an EC meter is convenient. If your plant nutrient recommendations are in ppM values, a sodium chloride TDS calibration is easier to use.
