The best TDS values fall between 750 ppm and 1500 ppm, depending on the maturation of your plant and the number of nutrients it can absorb. You can go higher, but you risk overwhelming your plants with nutrients. When grown aeroponically or hydroponically, the pH level requirement lowers a bit. The value of 280 ppm is chosen as representative of pre-industrial air because it is close to the average of CO 2 measured and dated with high time resolution between the years 1000 and 1800 in an ice core from Law Dome, Antarctica.

If you start pulling vacuum on a system that contains X ppm of water in air, you would be evacuating air together with water molecules. Assuming that the air-water mixture is homogenous, the resulting ppm of water in air will remain unchanged. Think of this as if you have 1 liter bottle of 5% solution of NaCl in water. 2020-06-03 Note: PPM and MG/L are the same thing. Water Hardness Chart. Treated (or softened water) = 0-1 GPG (total grains x 17.1 equals ppm) Slightly hard = 1-2 GPG (total grains x 17.1 equals ppm) Medium Hard = 3-7 GPG (total grains x 17.1 equals ppm) Hard = 7-10.5 GPG (total grains x 17.1 equals ppm) Extremely Hard Water = 10.5+ GPG (total grains x 17.1 equals ppm) - First we define the water temperature for the reference state - Then we assume that X = 280 ppm for the reference state - Finally we assume that (Ca 2+) = 10.24 mmol/l for the reference state - We calculate (H 3 O +) and pH = -log(H3O+) from equation (13).
