What is the structure of hydroponics?

Hydroponics is a method of growing plants without soil, using nutrient-rich water instead. The structure typically includes a growing medium (like clay pellets or rock wool) for root support, a nutrient reservoir to hold the water and nutrients, and a delivery system (like drip lines or flood-and-drain systems) to provide the plants with the necessary nutrients. Additionally, hydroponic systems may incorporate grow lights and environmental controls to optimize growth conditions. Overall, the focus is on providing efficient nutrient uptake and optimal growth conditions for plants.
