A couple of weeks ago I mentioned heading to Pueblo to look at some commercial hydroponics operations. I’ve become even more excited about hydroponics as a strategy for farming and wanted to share with you some of the information I’ve been digging up (so to speak!)
Although hydroponics seems like a modern and high-tech form of farming (and it is), it has deep roots. (I swear, I’m not doing it on purpose.) The first hydroponic experiments, in fact, were done in the early 1600s by Sir Francis Bacon, who was the father of hydroponic growing, although he called it “water culture” – but Bacon’s plants did poorly in the distilled water that he thought would be the ideal medium. It took another century or so before early agronomists realized that the micronutrients present in ordinary water were necessary for plant vitality.
The word hydroponics was coined in 1937, and it was about that time that the agricultural world started to get seriously interested. In Latin, it means “water working.” Early hydroponics proponents made some exaggerated claims for the method’s potential – but even after discounting some of the hyperbole, hydroponics remains an extremely viable method of growing crops. Some of the key advantages of hydroponics:
- Hydroponically grown plants can be provided with the exact amount of water needed – not a drop more, not a drop less. In fact, the water use efficiency of hydroponics is astoundingly high – a properly-designed hydroponic setup will use 10% of the water it would take to grow in soil outdoors.
- Hydroponically grown plants require much less land surface. Plants can be stacked (or even placed on multiple-story buildings, for high-density areas) with extreme efficiency – a hydroponic greenhouse can produce as much plant matter as a conventional field ten times the size.
- Hydroponics requires no soil whatsoever, meaning that farming can be done in areas with poor or even no soil – famously, Wake Island was hydroponically supplied with vegetables during WWII.
- Hydroponic farms can be located wherever power and water are cheap, and can be placed in close proximity to the demand for the crop, reducing or even eliminating shipping costs.
- Because hydroponic greenhouses are environmentally-controlled, the need for herbicide and pesticide are greatly reduced or even eliminated – which also puts hydroponic farming 90% of the way towards organic certification without any extra effort on the part of the farmer. (note: it is fairly easy to get organic certification in a hydroponic operation, yes, organic is possible)
In coming weeks, I will talk more about hydroponics, and how existing conventional farmers can start adding hydroponic capabilities to their farms – and extra dollars to their bottom lines.

it is the best for water shortage area.
may i get the details to do that.
thank u
And, um, correction here, but Hydroponics is Greek.
