Beginning Hydroponics Revised Ed [Paperback]

However, based on this text alone, the reader has no real idea just how big the field of soil-less gardening has become. For example, a sizable amount of commercial tomato production in the United States is done hydroponically, and virtually all of the fresh lettuce in Japan is produced this way. Additionally, the technology has proven itself to be commercially viable for the production of a variety of specialty crops. After reading this book, I could easily think of five or six spin-offs for potential research.

Probably the best endorsement for the power and capability of this applied technology is the fact that more research is done in hydroponics by commercial growers and big multinationals than is done by (and this is in the United States context) both universities and the USDA. As an aside, although not originally intended as an application, more than a few enterprising individuals have co-opted its utilization, and advanced its development in order to cultivate, produce and distribute cannabis!

This in turn may or may not explain the reticence of the United States government, through the USDA, to fund research into improved hydroponic methods. However, a more reasonable possibility may be that the technology is first a proven concept and second is very highly developed. Still, there is considerable room for creative thinking, improvement, improvisation and innovation, as many an enterprising law-breaker has demonstrated.

On the other hand, foreign governments in arid regions of the world, such as Israel, the greater Middle East and the North African region, have invested heavily in hydroponics research as a means to simultaneously produce food for domestic requirements and to conserve scarce water resources. Israel in particular is very aggressive in its attempts to use hydroponics as a basis for export-led agricultural production.

Considering how long this book has been on the market (some 27 years), and how bad the situation in the world is with regard to hunger and food insecurity, and environmental degradation, I have to wonder aloud why environmental types like Lester Brown, Helen Caldicott and environmental groups such as the Worldwatch Institute, Sierra Club and Greenpeace have not bothered to champion this technology. Given all of the benefits of the technology, and the number of greedy corporate fingers using it to rake in beaucoup bucks, you have to wonder exactly where the priorities of many of the so-called 'eco-advocacy' groups lay, as they should be grinning from ear to ear over this water conserving (and in many cases water recycling), decreased energy, pesticide and fertilizer utilizing technology.
