Hydroponics is a method of growing plants without soils, instead it is grown in a water based, nutrient rich solution. It uses less water than soil based methods of gardening. It uses 20 times less water.

In this environment, no pesticide is necessary as the environment is sterile. The water is reused. This method is perfect in places that does not receive good amount of rainfalls. Some common plants grown are: lettuce, tomatoes, celery, etc. The plants grow faster in a hydroponic system.

The nutrients used in the solution are: fish excrement, duck manure, and fertilizers.

To grow 1 kilogram (2.2 lb) of tomatoes in soil requires 400 liters compare to 70 liters using hydroponics.  Since it takes much less water to grow produce, it could be possible in the future for providers in harsh environments with little accessible water to grow their own food.

Types of hydroponic systems.

  1. Wick System
  2. Deep Water Culture
  3. Nutrient Film Technique
  4. Ebb and Flow (flow and drain)
  5. Aeroponics
  6. Drip system

Let’s take a look at these systems.
