Hydroponic Growing Mediums:
In a traditional garden, plant roots are in the soil. They support the plant and search for food and water. In hydroponics, we often use a growing medium in place of soil. The roots
of a hydroponic plant do not work as hard as those of a plant grown in soil because their needs are readily met by the nutrient solution we feed them.
Ideal mediums are chemically inert, porous, clean and able to drain freely.
Many materials have been used as hydroponic growing mediums. These include: vermiculite, saw dust, sand, peat moss and, more recently, rockwool, perlite and expanded clay pebbles.
Today's popular growing mediums, perlite,
rockwool and expanded clay pebbles are described below
