Hydroponics is a sustainable and efficient way to grow plants without soil, using a nutrient-rich water solution. This technique allows plants to receive all the essential nutrients directly through their roots, which are typically supported by an inert medium such as Coco Fibre, LECA, perlite, vermiculite, or peat moss etc. Contrary to popular belief, hydroponics does not necessarily refer to growing plants in water or under lights. While water and artificial lighting can be components of a hydroponic system, the key aspect is the soilless nutrient deliverymethod.
