Pipeline hydroponics employs a closed circulation system that achieves a 30% reduction in the growth cycle of leafy vegetables by precisely controlling the flow rate of nutrient solution (0.5-1.5L/min) and EC value (±0.1mS/cm error). The yield per unit area is 3-5 times higher than that of traditional soil cultivation. The system is equipped with intelligent temperature control (±0.5℃) and LED light compensation, saving 90% of water and supporting three-dimensional planting. It is suitable for high-value crops such as lettuce and strawberries.
