: The Electrical Conductivity (EC) measures total dissolved salts, while pH dictates nutrient availability. Optimal hydroponic pH usually rests between 5.5 and 6.5 . 🛠️ The Practice of Soilless Culture
: Removing soil eliminates soil-borne pathogens and pests, allowing energy to be spent purely on growth. Physical and Chemical Dynamics Soilless Culture: Theory and Practice
In practice, soilless culture splits into two distinct operational branches: and Substrate Culture . 1. Liquid Culture Systems (Pure Hydroponics) : The Electrical Conductivity (EC) measures total dissolved
