Hydroponics

The term “hydroponics” originates from Greek hydro (meaning water) and ponos (work) – the word therefore means something like “to work using water”. Simply put, it means growing plants without the use of soil.

Most people imagine plants with their roots sunk directly in water without any substrate. However, this is just one of the types of hydroponic growing, known as NFT (Nutrient Film Technique). A number of varieties of NFT are in use worldwide and it’s a very popular hydroponic method. Nonetheless, there is a whole range of other such techniques – ebb & flow, drip irrigation, aeroponics, and many others.

 

Why does hydroponics work so well?

It’s simple. If you supply your plant just with the things it needs, at the time it needs and in an appropriate amount, it will be as healthy as genetically possible. With hydroponics, achieving this is easier than in soil.

Plants are hydroponically grown in an inert substrate through which you may supply a perfectly balanced and, pH-wise, ideally adapted nutritional solution in a highly solvent form. This allows plants to absorb all the necessary nutrients with very little effort compared to growing in soil, where the roots have to seek the nutrients out and extract them (this is true even when using the best organic soil and nutrients available on the market). The energy, which hydroponically grown plants would have to use for absorbing nutrients if they were they grown in soil, can instead be used for vegetative growth, flowering and creating rich buds.

 

Testing yields

If you grow two genetically identical plants, one in soil and the other hydroponically, and provide both with the best possible conditions for growth and flowering, you will almost certainly see the difference in yields, as well as in overall taste and potency. This is precisely why hydroponics is used across the globe by commercial food growers and increasingly by horticulturalists, who seek faster and better growth with larger harvest.
