Hydroponic Vegetable Gardening Indoors: Year-Round Harvests Without Soil

Indoor hydroponics lets you grow vegetables all winter—no greenhouse needed. Plants receive nutrients via water solution (pH-balanced), roots supported by clay pebbles, rockwool, or air (aeroponics). Light comes from sun or grow lights. Kits simplify startup; DIY systems use trays and reservoirs. Plants grow faster, larger, and cleaner than in soil. Ideal for small spaces and season extension.
