What’s the Difference Between Hydroponics vs Aquaponics?
– by Colle and Phyllis Davis

Hydroponics is a very recent technology first noted in the 17th Century; the name itself was only coined in 1937 from the Greek words for ‘water’ and for ‘work’ by William Frederick Gericke of the University of California at Berkeley. He grew a 25′ tomato plants in his backyard using only mineral salts in water.

As amazing and productive as hydroponic is, there is a built in problem with the technology. The nutrient solution used in the growing of the plants eventually has to be ‘changed out’ or it will become toxic to the plants, even if the system is being run organically because some of the nutrients become concentrated in the water and even adding water to dilute it, there comes a time when it must be changed out. Therein lies the rub . . .

The ‘liquor’ as it is called, is now designated by the EPA as toxic waste and must be disposed of properly by qualified personal using approved techniques. Another way to say this is that the waste disposal for hydroponics is expensive and needs to be disposed of by experts. This makes the hydroponic waste removal a much larger expense than most people realize and it’s a topic that’s almost never discussed by those selling hydroponic systems.

Hydroponics has a much older and more benign sister, aquaponics that has been around for over 4,500 years and is the exact same system that nature uses to break down waste to reuse the resulting byproducts to grow new plants and this process has been going on naturally for billions of years.

The waste products in aquaponics are non toxic, usable on other plants and can even be dumped down a sewer system because they will not harm sewage systems. The waste from an aquaponics system is a valuable fertilizer for plants, shrubbery, trees, or grass. One owner of a small commercial Portable Farms® Aquaponics System even sells his Settling Tank waste as an organic fertilizer and gets US$25 per 5 gallon container and the client picks it up at his greenhouse. Considering that each Module of Portable Farms® produces approximately 50 gallons of waste water every six weeks which can become a nice extra source of income for the installation owner.

In aquaponics, there are no toxic chemicals used because they might kill either the plants or the fish.

Insecticides that help control pests on the plants will nearly always kill the fish. Organic becomes a way of life which makes for a much safer and healthier food supply. Portable Farms® Aquaponics Systems are organic by definition because they contain NO dirt and use no chemicals (insecticides or fertilizers) to grow the plants.

Today, your family can enjoy one of the oldest food-growing technologies wrapped up in a modern, easy to build and operate system in your own backyard, patio or greenhouse.

    I read about Brightfarms which is operating greenhouses using hydroponics. I am wondering they would be better off with aquaponics instead. Maybe AQ is a bit complicated and fish is not what they want?

      James,
      Everyone has to make these type of choices for themselves. Aquaponics is actually less complicated because you are not adding chemicals all the time.
