pH & EC Management

Water pH and EC of are two of the most important factors to consider in hydroponics. Carefully checking and adjusting these values avoids nutritional problems and highly improves yields.

pH indicates the level of water acidity/alkalinity, which is directly related to nutrient uptake. The ideal pH for cannabis is between 5.5 and 7. Many nutrients can't be correctly absorbed if the pH value is not accurate, thus resulting in problems and poor yields.

EC indicates the level of water conductivity (the amount of salts). Obviously, the more nutrients used the higher the EC value will be. Desirable EC values for cannabis range between 0.60 and 2.00 mS.

With brands like GHE or Milwaukee, we offer here a wide range of pH and EC meters, from manual to continuous meters, as well as automatic pH controllers. You'll also find calibration, cleaning and storing solutions for the maintenance of your meters, also to increase or decrease the pH of your water or nutrient solution.
