What is pH? pH (short for potential Hydrogen) is the measurement of acidity and its opposite, alkalinity in a solution. Neutral pH is 7.0 pH. Acidity measures below seven pH (7.0pH) with alkalinity measuring above it (7.0pH). Why is it important to measure pH? It is important t ...

What is conductivity? Conductivity (measured in ppm, EC, TDS, CF) is the total soluble salts contained within a liquid solution. Pure water does not contain salts, so it has a conductivity measurement of zero. By adding soluble elements to the water, electricity is able to move through the solution giving it a conductivity rating. ...

Although there are ideal EC values for each plant type, this does not mean that a range of plants, all technically requiring different strength nutrients, cannot be grown in a home situation together. The grower simply lists the range of EC values and picks an average value. For most home systems this value is between 1.2EC and 2.0EC depending upon the requirements of the predominant crop types ...

Hard water results primarily from excess calcium, magnesium, sodium and other minerals dissolved in the ground water. Too much of any of these can greatly alter the mineral nutrient balance in the root zone and nutrient reservoirs. Sodium, for instance, competes with Potassium and you may end up with Potassium deficiency symptoms like brown leaf tips and less than optimal growth ...
