Hydroponics

Definition - What does Hydroponics mean?

Hydroponics is a method of growing plants without using soil (i.e., soil less). This technique instead uses a mineral nutrient solution in a water solvent, allowing the nutrient uptake process to be more efficient than when using soil. There are several types or variations of hydroponics.

MaximumYield explains Hydroponics

Hydroponics is suitable for commercial food producers and hobbyist gardeners alike. Hydroponics possesses several advantages over a soil medium. Unlike plants grown in soil, plants grown in a hydroponics system do not need to develop extensive root structures to search for nutrients. It is easier to test and adjust pH levels. In the hydroponics method, plants are raised in an inert and perfectly pH balanced growing medium where the plants only need to expend minimal energy to acquire nutrients from the roots. The energy saved by the roots is better spent on fruit and flower production.

There are several types of hydroponic growing techniques, including:

  • Nutrient film technique (NFT)
  • Wicks system
  • Ebb and flow (flood and drain)
  • Water culture
  • Drip system
  • Aeroponic system

Aquaponics is hydroponics combined with aquaculture (raising fish).
