What is EC, and how does it work. This is a common question for new growers, especially if you are thinking about growing cannabis hydroponically. When growing in hydroponics, or mediums like coco, it is common for growers to use “salt based nutrients”. These nutrients, when added to water, will change the EC (electro conductivity) of the liquid. This means, electricity can pass through the water easier, by moving through the salt particles. This essentially, is what EC is. By measuring the conductivity of the water, you can tell how much food is in it. When you first test the
