Hydroponics is the use of chemical nutrients to grow plants in a medium that does not contain soil. The nutrients used in a hydroponics system contain the typical N-P-K (Nitrogen, Phosphorus, and Potassium) that we are taught that all plants need for growth.

Are there chemicals in hydroponics?

Hydroponics is the eco-friendly gardening solution for several reasons. It requires only 10% as much water as you would need for soil. In a hydroponic system, the water supply is cycled repeatedly to deliver nutrients to the plants, so there's far less water loss. Most hydroponic systems require no pesticides.

Why is hydroponics bad?

Hydroponics has a reputation for being sterile. This may include real consequences for farmers who use these techniques to make a living. The danger is that a failed bid for organic certification could set a dangerous precedent, leading to a large scale devaluation of the industry.
