In traditional agriculture where plants are grown in soil, nutrients and water exist randomly, and often plants need to expend a great deal of energy to grow long roots to search for water and nutrients. By expending this energy, plants do not grow as fast as they could. However in a hydroponic system, a plant doesn’t have to expand any energy growing long roots in search of it. In addition, growing plants in hydroponics requires less water, less space, and pests and diseases are more easily controlled and prevented.
