BASIC HYDROPONIC PRINCIPLES Plants require light, oxygen and carbon dioxide while the plant root system require water, nutrients and oxygen. When plants are grown normally in soil, water converges nutrients from the soil and carries them to the roots. Water and nutrients are absorbed by the roots to fuel plant growth. Soil drainage therefore allows you to replace water with air in the spaces between the soil grains, and provide oxygenation to the roots. With hydroponic, nutrients are dissolved in water. The soil is replaced with a growing medium…
