Hydroponics
Hydroponics means growing in a soilless mix that serves to anchor plant roots. Hydroponics allows the grower to control fertilizer (nutrient) levels and uptake by plants. Hydroponic grow mediums provide more air space around roots, and nutrient uptake is faster than in soil gardens. Hydroponic gardens require more control of water, pH, nutrients, and the root-zone environment. Hydroponic gardens can be very simple and inexpensive or complex and expensive.
