概要	Hydroponic nutrient solution management involves formulating, monitoring, and adjusting the chemical composition of water-based growing media to deliver optimal nutrition without soil. This method combines analytical chemistry (nutrient analysis, pH, electrical conductivity) with plant physiology to diagnose deficiencies and optimize yield and quality. It is essential for commercial hydroponics, vertical farms, and propagation systems where precision nutrition directly impacts profitability.	Greenhouse climate control integrates measurement, modeling, and automated actuation to maintain optimal temperature, humidity, light, and CO₂ concentrations for plant growth. Modern systems use sensors and control algorithms to respond dynamically to external weather and internal plant needs. This approach increases yield, shortens crop cycles, reduces disease pressure, and improves energy efficiency compared to manual or static setpoint controls.
