Hydroponics & Indoor Growing
📋 What it is
Hydroponics grows plants in nutrient-rich water instead of soil, often indoors.
🗣️ Coach says
Plants don’t strictly need soil — they need water, nutrients, light, and air at the roots. Hydroponics delivers nutrients in water directly, growing plants without soil, often indoors or in cities. It can save water and grow food in surprising places, like rooftops and even space stations.
🧠 Memory hook
Hydroponics = grow in nutrient water, no soil. Saves water, grows anywhere.
