Hydroponics is soil‑less crop production, where plants grow in a nutrient‑rich water solution instead of soil. The core idea is simple: give the plant exactly what it needs—water, oxygen, and minerals—in a controlled environment so it can grow faster, cleaner, and more efficiently. Hydroponics uses 80-90% less water than soil farming 2) Vertical stacking allows high density production 3) Plants mature faster due to optimized nutrition 4) Year-round production in controlled environment.
