Hydroponic pH & EC Control
The pH & EC levels in a hydroponics system is an important, yet often overlooked aspect of growing. Even though plants have different optimal pH & EC levels, most plants thrive best in the slightly acidic pH range between 5.5 to 6.0 and with an EC (electrical conductivity) range between 1.5 to 2.5. In order to maximise the presence of nutrients in your solution, we recommend regular testing of pH & EC, and adjusting the levels as needed. Please see our Complete EC & pH levels chart for hydroponic plants for more information.
