can someone explain ec to me and how it works etc...?

hi can someone please explain ec to me and how it can be measured thanks ?

EC (electrical conductivity) measures the amount of salts or "stuff" to make it easy in your water... its a universal way to accuratley measure PPM (parts per million) since PPM changes depending on which method you use to figure it... you can measure EC with an EC meter... thats the only way to know what your EC is... its definatly more complicated than what i said... but to keep it exretmely simple thats what it is... a MUCH MUCH more accurate way of measureing figuring out your PPM...

it's a measuremented of dissolved solids in a liquid. It measures the electrical conductivity of the liquid. The more dissolved solids "ions" the greater the conductivity. Most ppm is based off of this measure. There are different conversion factors 500/700. ex. (.1 ec = 50 ppm)/(.1 ec = 70 ppm)

EC is electric conductivity in a liquid. Plain distilled water has an ec of 0 because there are no total dissolved solids (tds) in it. The more nutrients in the water the more tds - therefore the higher the ec reading. The meters that most of us use to measure ec is actually an instrument to measure ppm (parts per million). These meters convert ec into ppm to tell us what strength our nutrient solution is. Different manufacturers use different conversion methods to determine ppm. Some are 500 ppm = 1.0 ec and others are 700 ppm = 1.0 ec, so it's important to know what conversion method is used for what meter you have. For instance I have a Hanna ppm meter that has a conversion of 1.0 ec = 700 ppm. So when my ppm meter reads 800 ppm - that is equal to 1.14 EC. It's very important for your plants health to know how strong your nutrient solution is, otherwise you can fry it with too strong of a solution.
