The term “Hydroponics” was coined in the 1930s by Dr. William F. Gericke, a professor at the University of California. The word was created to describe the agricultural applications of hydroponics, taken from the Greek words hydro (water) and ponos (labor). His work in extending laboratory applications to large agricultural crop situations is considered the foundation from which hydroponics was born.

Why (Simplified, Non-circulating) Hydroponics?

Hydroponic crop production can be superior to soil-based farming in several respects: (1) land is not needed; (2) problems associated with continuous cropping are avoided; (3) no weeds and soil-borne pests and diseases, so less pressure to use pesticides; (4) shortened growth period; (5) higher yields in smaller areas due to closer plant spacings and 2- or 3-level production schemes; (6) elimination of costly operations like land preparation, weeding, and irrigation, and (7) less physically-demanding on the farmer.  It is also environmentally more friendly, mainly because of the avoidance of erosion-causing soil manipulation, fertilizer run-off, large water draw for irrigation, and pesticide use (for example, use of herbicides, nematicides, and soil insecticides are totally avoided).

Yet modern hydroponic systems are high-tech operations, with fully computerized and automatic control of solution pH and electrical conductivity (EC), air and solution temperature, nutrient analysis, etc. These need special equipment for pumping, circulating, flowing, misting, dripping, etc. of nutrient solution.

In recent years,  a hydroponic system which does not require costly facilities, high running cost and intensive care has been developed independently by the University of Hawaii (Dr. B.A. Kratky), the Asian Vegetable Research and Development Center (AVRDC) in Taiwan, and the University of the Philippines Los Baņos in the Philippines (called SNAP Hydroponics, developed by Eureka Teresa M. Ocampo and Primitivo J. Santos). All three share the same major characteristic—the nutrient solution stays in the production boxes until harvest and is not circulated nor re-adjusted. Now, the benefits of hydroponics is within reach of ordinary farmers and gardening enthusiasts, even in off-grid areas, marginal lands, or tight city spaces.   

I have combined elements from all three systems and even from traditional hydroponics (in regard to the composition of the nutrient solution), added some production methods of my own, and simply called my system Simplified, Non-circulating Hydroponics.

2. TRANSPLANT INTO GROWING BOXES PREPARED WITH NUTRIENT SOLUTION.

3. WAIT UNTIL HARVEST. NO WATERING, NO WEEDING, LESS PESTS & DISEASES. 2-3 DECKS MULTIPLY YIELD.

The Challenge of Feeding Thousands
 
WAR AND PEAS
 

By the 1940s hydroponics was being used to feed US troops on non-arable pacific islands. Feeding troops across the globe became a primary function hydroponics, which was utilized by both the British and American armies who rekindled and financed interests in hydroponics systems. Hydroponics systems were built on coral reef islands and provided troops with fresh vegetables they would not have otherwise had access to. Service crews were able to be supported on Ascension Island in the south Atlantic through hydroponics, and similar systems on atolls in the pacific supported troops there. The British army employed hydroponics in their desert bases in Iraq. The success of these systems led the US army to develop an entire post war hydroponics division, and yields of 8,000,000 pounds of crops were produced in 1952.
