Hydroponic vs. Substrate-Based Fertigation: Control System Considerations
Hydroponic and substrate-based growing systems can both produce uniform, high-value crops. They use water, nutrients, oxygen, and irrigation timing differently. A good fertigation controller reflects those differences. Deep-water culture, nutrient film technique, and substrate-based crops each need a unique balance of EC, pH, oxygen, flow, moisture, and irrigation timing. Start with the Root Zone The […]
