Inexpensive and Sustainable Food from Hydroponics

Hydroponics Bring Low-Cost Solution to High Food Prices

Science News by NewsLook

 

A low-cost, easy to use hydroponics system developed in the Philippines is giving small communities with little land an inexpensive way to produce their own vegetables. The system is designed to maximize yields from limited resources and is already proving its worth with bumper harvests of inexpensive, locally grown vegetables. Photo Credit: Kanu Hawaii via Flickr.

I invite you take a look at my Aquaponic garden page where I use PVC pipe, soda bottles, and fish to grow plants. The instructions are right here for free. http://do-it-yourself-hydroponics.moderngrower.com. I think this is the easiest and for sure the cheapest way to grow lots of plants almost hands free. It can be done with or without fish! Enjoy!

Joanne M, The internet is full of info on hydroponics, but might I suggest that you consider going organic and lean towards aquaponics.

With aquaponics, you actually producing three continuous crops. The Tilapia produce a great deal of waste, which is converted to a nutrient for your plants. So this helpful bacteria plays an equal role in aquaponics and is of great importance.

Great info - I would like to get more info.

Bill L, Yes, vermiculture, tilapia love worms, and Black Soldier Fly Larvae. Actually there are so many ways to lower feed cost, and increase growth rate.

We produce the majority of our feed from scratch, and OMRI, our Organics certifier approves of our procedure.

So there you are, the future of farming. One that can be placed in any community, whether it be a city, town, suburb, or in the country.

Aquaponics is the answer.

Might I add a few plus's, No E-coli, No Salmonella, less problems with plant diseases'

Over the years, I have worked with issues of black and grey water, bioremediation, raised fish and produced fruits, veggies and herbs in hydroponics. On day, it occurred to me that all of this training had prepared me to take a step beyond, into aquaponics.

We use 4 fish tanks, Tilapia in various stages of growth, fish pee & poop, yes in Aquaponics we say poop.

The plants reside in rafts which float in concrete canals (6). The fish "wastes" are high in ammonia, the liquid is sent to filter tanks and orchard net flocculates the waste, now we have a nitrite, still too toxic. As it continues in the tanks, we introduce aeration, now we realize a nitrate, a usable form, which is combined with iron chelate, we have a perfect nutrient solution and off to the veggie canals.

The veggies are contained in round mesh baskets, they uptake the nutrients, cleansing the water, which is returned to the fish tanks.

This is a brief description, but Aquaponics is in fact the best means to an end. While we utilize 112,000 liters of water, we replace only 4% per year, due to evap. and spillage.

Who doesn't like to snuggle with a cat? The little chick must have imprinted on the cat so I do hope…

Thank you Dr. Vegan.

It's probably one of those old remedies of years ago when the average life span was about 40 years.
