Flood and Drain systems ensure optimal nutrient delivery by periodically flooding the grow tray with a nutrient-rich solution, allowing the roots to absorb the necessary nutrients. The frequency and duration of the flooding cycle are critical factors in ensuring that the plants receive the right amount of nutrients. The system’s design should take into account factors such as plant type, growth stage, and environmental conditions to optimize nutrient delivery. Additionally, the system should be designed to prevent waterlogging and ensure adequate drainage to prevent root rot.
