A seasonal chart showing the recommended pH and EC levels for growing hydroponic plants in clay balls, coco or soil.


EC & pH levels for hydroponic plants

In order to get the best results from your hydroponic plants, it is recommended to give them the optimal growing conditions. The handy chart below shows the recommended EC (electrical conductivity), pH (potential hydrogen) and the best hydroponic or organic soil growing media for each type of vegetable. Hydroponic grow medias include Clay Balls/Perlite, Coco Peat or a quality soil based grow media known as Terra (such as Canna Terra Professional soil or a quality soil from OGS or Dr. Greenthumbs).
