Aquaponic Greenhouse Prototype for Kenya
By Faith And Sustainable Technologies
Prototype aquaponic (combination of hydroponics and aquaculture) system using 700 gallon elevated ferro-cement flood tank technology developed by Travis W. Hughey which uses no float switches, electronic timers or microprocessors to control the flood and drain parameters of the system. It is a large version of the flood tank in the “Barrel-Ponics” manual found on this site as a free download. The system uses approximately 400 gallons of water per flood cycle. There are 37 barrel half growbeds also of Travis’s design incorporated. In the shallow pond water hyacinth and water lettuce are grown for fish feed.
The entire system consumes less than 400 watts. The vegetable production is over twice what can be grown in the same square footage of soil. Fish are also harvested and excess vegetation is either fed to the fish or composted to build healthy soils. It is our desire to use such systems to replenish depleated or erroded soils in places that can no longer support farming and reclaim the losses of bad management. There is no soil in the system itself with only gravel as the growth media with nutrients provided by the fish.
Morning Star Fishermen’s Aquaponics Education Program
The aquaponics courses held at the training center will teach students all of the basic skills and knowledge necessary to successfully breed and grow Tilapia and culture plants and vegetables “aquaponically” on a practical, self sustaining, “back yard” scale, as well as larger commercial scale. The courses include topics in Tilapia and aquaponic plant culture, breeding setups, equipment, reproduction, growth procedures, purging or cleaning, and harvesting of the fish and vegetables.
New Book: The Aquaponics Guidebook
“Replace an aquarium filter with a pot of gravel. Put a plant in the pot. Let it drain back into the aquarium. That’s aquaponics, boiled down to its simplest form.
“Now, consider it on a bigger scale: An above-ground swimming pool with 3000 gallons of water. 4-foot wide grow bed trenches and lined with rubber, stretching 100 feet. Out of this system a staggering amount of vegetables and fish protein can be produced, to be consumed, traded or sold. Inputs are fish food, electricity and a modest amount of maintenance.
“Or how about this: Water from a fish pond is pumped up hill and filtered down through gravel grow beds. The clean water trickles back into the pond. Nothing is wasted. The excess nutrients provide a valuable crop.
“Aquaponics is simple and it works.
“It’s also curious that it hasn’t caught on in a bigger way, for all the clear and immediate benefits it provides.”
