Hydroponics
What is hydroponics ?
Hydroponics is an agriculture
method that uses water only
and no soil at all.

Facts about Hydroponics.
Fact 1 : Nowadays, food-growing techniques depend heavily on
pesticides and chemicals, which negatively impact the water and soil.
Water and soil pollution, along with large-scale depletion of the topsoil,
speed up climate change. Phenomena related to it are affecting the
ability of the land to grow crops, leading to worldwide food shortages. In
recent years, agricultural practices have seen a major shift towards
sustainable food-growing methods, including permaculture, crop rotation,
polyculture, and hydroponic farming. We take a look at the latter and
analyse its potential benefits and disadvantages.
Fact 2: Hydroponics Uses 90% Less Water
Growing plants the traditional way in soil is remarkably wasteful of
water. Hydroponic plants require up to 90% less water to make them
grow successfully. A large proportion of the water used in soil-based
gardening is lost into the ground and not absorbed by the plants.
Most hydroponics systems recirculate any water and minerals used so
that the only losses are from evaporation. Some systems even capture
this evaporated water and return it to the system. Hydroponics is
therefore a fantastic option for countries where water scarcity is an
issue.
Fact 3 : No Soil Required
Growing plants using hydroponics means using no soil at all. All you
need is water, oxygen and nutrients to ensure that hydroponic plants will
thrive. As a result, you can grow hydroponic plants anywhere at all, inside
or outside.
Fact 4: Hydroponics Has Many Forms
Hydroponics isn’t just one way of growing plants. In fact, there are at
least 6 or 7 main recognised subsets of hydroponics and many more
variations of these. The most common forms of hydroponics are.
How many techniques of hydroponics are there?
There are 7 kinds of techniques
1. Nutrient Film Technique (NFT)
2. Deep Water Culture (DWC)
3. Wick Hydroponics/Wick System
4. Ebb and flow/Flood and Drain system
5. Drip Hydroponics/Drip System
6. Aeroponics
7. The Kratky Method of Hydroponics
