ppm is used to measure chemical concentration, usually in a solution of water. Solute concentration of 1 ppm is solute concentration of 1/1000000 of the solution. The concentration C in ppm is calculated from the solute mass m solute in milligrams and the solution mass m solution in milligrams . C (ppm) = 1000000 × m solute / (m solution + m solute) Water hardness follows these guidelines: 0 - 4 dH, 0 - 70 ppm : very soft 4 - 8 dH, 70 - 140 ppm : soft 8 - 12 dH, 140 - 210 ppm : medium hard 12 - 18 dH, 210 - 320 ppm : fairly hard 18 - 30 dH, 320 - 530 ppm : hard higher : liquid rock (Lake Malawi and Los Angeles, CA) General hardness is the more important of the two in biological processes. Hard water is water that has high mineral content. Hard water is formed when water percolates through deposits of limestone, chalk or gypsum which are largely made up of calcium and magnesium carbonates, bicarbonates and sulfates.

With soil cultivation, the water ppm should be checked after adding additives to the watering vessel. For hydroponic use, check the reservoir. With too low ppm, add more nutes, and with too high, dilute with water until you reach an optimum level. In fact, we use some types of filtration media that actually add minerals to the water, so TDS/ppm levels in water filtered through a Hydroviv system are sometimes slightly higher than unfiltered water.
