Amongst one of the few properties that hydroponic growers use hydroponics ec to control their nutrient solutions is electrical conductivity (ec). the main problem with the measurement of the ec, is that few growers really understand it’s meaning and more often than not, grossly overestimate the amount of information it can give them.

Well, a vast majority of nutrients used in hydroponics involve salts like nitrates and phosphates. so adding nutrients increases the ec of the water. if you get the measurement of ec, you can get a pretty good idea regarding the levels of nutrient concentration in your water. ec is measured using two connected units.

To get an ec value, multiply the ppm reading by 2 and divide by 1000. thus, if your ec is 1: 1*1000/2= 500 ppm. and if your ppm is 500: 500*2/1000= 1 ec. is it better to use an ec or a tds meter? if you have plant nutrient recommendations in ec units, an ec meter is convenient. hydroponics ec trays rotating gardens top feed drip hydroponics vertical hydroponics fertilizers / maintenance solutions meters and testers containers plant care books & videos hydro systems ph/ec maintenance water filtration user guide what is hydroponics ? benefits of hydroponics grow light systems advanced nutrients Electrical conductivity (ec) of the hydroponic nutrient solution electrical conductivity (ec) is an indirect way of measuring the concentration of your nutrient solution. an ec meter will measure the electrical conductivity of the solution.
