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.

KLASSIFICERING ENLIGT CLP (FÖRORDNING 1272/2008/EC). GHS02, GHS07, Fara: NGV = 600 ppm; totalt 1800 mg/m3. KGV = 750 ppm 

200 ppm to parts per billion. 200 ppm of 10 PPM and EC. Any serious conversation about ppm will also touch on ec; it almost seems inevitable since the two are closely related. EC stands for “electrical conductivity.” Using an EC meter measures the electrical conductivity in the water you’re using, and this reading is useful for measuring the amount of dissolved solubles in your water. El PPM, o partes por millón, es una forma de expresar concentraciones muy diluidas de sustancias. Una parte por millón (ppm) denota una parte por cada 1,000,000 partes, una parte en 10 6, y un valor de 1 × 10-6.

PPM (Hannah) EC (mS/cm2) Early Growth: 400 - 500 ppm: 0,8 - 1: Seedling: 500 - 600 ppm: 1 - 1,3: Transition: 600 - 750 ppm: 1,2 - 1,5: Vegetative Stage: 800 - 850 ppm: 1,6 - 1,7: Vegetative Stage: 850 - 900 ppm: 1,7 - 1,8: Vegetative Stage: 900 - 950 ppm: 1,8 - 1,9: Flowering Stage: 950 - 1000 ppm: 1,9 - 2: Flowering Stage: 1000 - 1050 ppm: 2 - 2,1: Flowering Stage: 1050 - 1100 ppm: 2,1 - 2,2 You now have actually exceeded the manufacturers recommendation by 600 PPM @ 0.7 conversion by running at 3000 µS * 0.7 = 2100 PPM @ 0.7 conversion. To convert a PPM figure back to an EC figure is a simple matter of division.

Convert Parts Per Million to Milligrams Per Milliliter (ppm in mg/ml). Parts Per Million and Milligrams Per Milliliter both are the units of DENSITY. See the charts and tables conversion here!

Parts Per Million and Tons [metric] Per Cubic Kilometer both are the units of DENSITY.
