Hydroponic Gardening: Growing Without Soil

Lush, healthy indoor plants and premium-grade vegetables grow quickly with hydroponic-gardening techniques, but the key is adding the proper nutrients and trace elements to the water trays in which they are grown. Taking the guesswork out of the process, this guide provides nutrient formulas for many kinds of plants and explains how to monitor their effectiveness. The overall benefits of hydroponics are also praised, including the elimination of weeding, the protection of crops from bad weather and insects, and as an alternative for people with back and knee problems or for those who don’t have much outdoor space for gardening. Additional discussion covers selecting a basic system, automating a system, starting plants and seeds, and preventing plant diseases and pests.
