WHAT IS GROWING MEDIA? Often also referred to as substrate or potting mix, a growing medium is a material, other than soil in the ground, in which plants are grown.
In nature, plants grow in soil or water. Some plants even grow on rocks or tree branches. A basic requirement for all plant growth is that the medium in which they grow can hold the roots. Fixation is needed to anchor the plant and to provide the plant with water, oxygen and nutrients. If fixation is not needed, like for plants in supporting frames or hanging on ropes, plants can also grow in water or mist systems In soilless culture or hydroponics, soil is mimicked by the use of a growing medium.
In fact, plants can grow in anything, as long as there is water, sufficient nutrients and oxygen available and contains no hazardous components naturally.
