Hydroponics is a subset of hydroculture and is a method of growing plants using mineral nutrient solutions, in water, without soil. Techfil’s range of Expanded Clay Media is dust free and contains very low levels of leachates making it an ideal growing medium. Plants may be grown with their roots in the mineral nutrient solution only or in an inert medium, including Expanded Clay, Perlite or Gravel. Techfil also offers the full range of Perlite and Gravel.
