Understanding Electrical Conductivity (EC) in Your Hydroponic System Water Management Plan

Now that we understand the importance of pH, let’s look at Electrical Conductivity (EC) and its importance in our hydroponic system water management plan.  Conductivity, often referred to as EC, is a measure of the salts or nutrients present in your hydroponic system’s water. It indicates the availability of nutrients for your plants in the water.

These “salts” encompass substances like sodium chloride (common salt), calcium, magnesium bicarbonates, chlorides, and sulfates. Sodium and chloride are the most common, but at high levels, they can be harmful to plants. Sulfates, calcium, and magnesium are essential nutrients, but they can make the water “hard,” affecting its pH, as discussed earlier.

In a recirculating hydroponic setup, excess salts can accumulate and clog the pipes, especially in hot grow tents where water evaporates, leaving behind more salts. This leads to a higher EC, which can harm plants by either providing too many nutrients or diluting them excessively.

Measuring Electrical Conductivity (EC)

To measure EC effectively, aim for a range between 1.2 and 2 for optimal nutrient delivery. Also, check the parts per million (ppm) of the water. If tap water has a ppm of 300 or higher, it should be distilled or undergo reverse osmosis water treatment. Ideally, your water’s base ppm should be between 0-50 before adding nutrients. A ppm exceeding 100 may indicate the presence of harmful microbacteria.

To measure EC accurately, consider using an EC Meter, which measures both conductivity and pH. This ensures you maintain the right nutrient concentration without over- or under-diluting the nutrient solution.

Changing the Electrical Conductivity (EC) of your Hydroponic System

If the EC is too high, dilute it with fresh distilled water. If it’s too low, supplement it with extra nutrients.
