Hydroponics is a method of growing plants using mineral nutrient solutions, in water, without soil. Terrestrial plants may be grown with their roots in the mineral nutrient solution only or in an inert medium, such as perlite, gravel, mineral wool, or coconut husk. Researchers discovered in the 18th century that plants absorb essential . . . → Read More: Hydroponics Techniques The two main types of hydroponics are solution culture and medium culture. Solution culture does not use a solid medium for the roots, just the nutrient solution. The three main types of solution cultures are static solution culture, continuous-flow solution culture and aeroponics. The medium culture method has a solid medium for the . . . → Read More: Hydroponic Techniques
Expanded Clay One of the most obvious decisions hydroponic farmers have to make is which medium they should use. Different media are appropriate for different growing techniques. Expanded clay (Ex-clay) Baked clay pellets, also known under the trademarks ‘Hydroton’ or ‘Hydrokorrels’ or ‘LECA’ (“lightweight expanded clay aggregate”), are suitable for hydroponic systems . . . → Read More: Hydroponic Mediums Hydroponics is a method of growing plants using mineral nutrient solutions, in water, without soil.
