Backyard aquaponics as self-sustained farm in (sub)urban LA

8285 ratings | 847419 views
Scott Henley wanted to prove he could turn the backyard of his modest Pasadena (Los Angeles) home into a working farm. To turn his 8000-square-foot backyard into a productive farm, Henley turned to aquaponics- a combination of aquaculture (fish farming) and hydroponics: "This is a very efficient way to grow things in a small space. And it also produces a protein source." He farms tilapia because they breed fast. The fish waste is broken down in the water by naturally-occurring bacteria into nitrate. The plants take up the nitrates as food and the now-cleaned water is fed back to the fish and the process begins again. The only inputs are sunlight and fish food. It's an inherently organic system because any pesticides would upset the natural balance of the small ecosystem. After less tha 2 years in operation (he started in the summer of 2012), he- through Whisper Farms- now sells enough produce to restaurants, CSAs and at the local (Altadena) farmer's market- to cover all costs and produce a small profit. His "experiment" is still not productive enough to create a salary, but he hopes that will change once he's able to sell his fish and create more of a cooperative setup with other farms (to reduce the permitting costs for selling at farmers' markets).

Imagine if the government came to tell you can't grow anything but bananas? Even for personal consumption? You resist, then the come in middle of night to r*ape your wife and kill all the males. Sadly this is exactly what the US did to all latin America. It called the banana massacres. Still going as we speak. We don't realize how free we are here.

Came to the video expecting some yuppie dipshit and my dude turns out to be the real deal! I learned how to do all of this in conservation school back in the late 90's early 00's, good to see this practice is not only still going strong, but spreading to urban areas. Everything looked DiY, impressive!

Why don't you grow apples, cherries, peaches, blackcurrant and etc? Chicken need normal grass and some other cover crop to feed onto. YOu could maybe make a pond.
Sammy West (1 month ago)
The apples and cherries, and peaches all require a tree to grow from. It would take quite a few years for a tree to produce any results.
Panthera (1 month ago)
YOUR PROBLEMS: grown in plastic which leaches chemicals almost no soil and no correct microflora (microbes, fungi etc) need fertilisers fish locked up like in small jail cell for life Look into permaculture Gabe Brown, Geoff Lawton, Learn Organic Farming. Chicken MUST HAVE fresh grass and maybe some other cover crops like leafy greens mixed in, maybe some clover, maybe something else.

One thing I've yet to find out. Do you need to do a water change with aquaponics? Cause eventually the oxygen and any other nutrients get used up right? Everyone says it's fine to keep recycling the water. That true? Water like a trickle system be good enough?

This is a serious question, why are common gold fish look over as a viable alternative to tilapia in colder waters? I'm talking fry to fried. They grow fast, they are easy to keep, a green water system will almost feed them and they breed easily. Carp are eaten all over the world.

Great work. Better double-check that protein content of the moringa though - 38 - 39% is a bit higher than most studies show. In the leaves the content in about 25%, less in the stems. Depending on the variety and growing conditions 15 - 30% protein content for the whole plant is usual. More importantly, what are the amino acid (AA) bonds in the protein? If the human can not make the specific enzyme required to break those bonds, the amount of protein does not matter. If you can't break it down, the body can't use it - and, in fact, indigestible dipeptides (2 AAs) may hinder or impair the ability to adequately digest those AA bonds humans can break down. This, theoretically, could lead to a lowering of the available AA pool, given that the diet contains more than one source of protein. Also important is the ratio, and type, of AAs used to make the plant protein - the human body has a specific ratio of AA needed for each protein of which about 20 must be obtained by diet. If this plant uses AAs that are not usable by humans, it reduces the efficiency and if of the ones humans can use, there are one or two essential AAs missing, the body can not manufacture any protein the needs the missing AAs. This is why moringa works in India and Africa - because it is the main, if not the only, source of protein, it will only add to the AA pool.

Loved to see what you are doing with your fish and plants. I hope to set that up similar in Washington state. We are originally from San Diego, moved to Virginia Beach for 17 years and now we want to find a place in Washington where the air is nice. We may have to do rainbow trout instead but I am excited to show my husband what you have done. I might do much of it indoors depending on the weather and animals there. Thanks for sharing. What you are doing is smart and great for your family!

I used to having scared feeling when I grew food at my backyard because it looked weird to me while our neighbors bought food from stores, and they looked at me when I picked food from my back yard to eat. But later years I thought about it and believed that they thought back then that I know how to grow food. Now I want to grow food without having weird feeling and see this gentleman is doing it, I am very excited about doing it too. Thank you for sharing this aquaponic systems.

I wonder if counter flow heat exchanger next to the fishtank would make a difference to the fish pool heat drain. It's basically a pipe inside a pipe. The outgoing hot water would give heat to the incoming cold water. The plant beds are essentially a large radiator. No idea about clogging, cost or corrosion. The temperature difference could also be so small between incoming and outgoing water that there's no point.

Even if you completely fed a family of four on that garden, you'd only be saving like $12k a year Food is only like 6% of the average persons expenses, that's never going to be better than just having both parents work.

no chemicals or pesticides and knowing for sure is worth more than 12k a year.

I don't get it, how do you provide your plant with macro- and mikronutrients, fish only provide nitrate which gets transform to nitrate by bacteria.

That's awesome and very encouraging for those who are looking at doing this . I like the realistic attitude and the can do attitude . I was doing Aquaponics before it had a word to describe it . I was interested in the fish keeping hobby since kindergarten when the Seattle aquarium brought their tide pool critters to our school and gave every child a couple of guppies to see if they could take care of them and be responsible .That was 41 years ago .Since then I've been active in the hobby and worked at a few places such as tropical fish hatcheries and a couple of pet stores . Aside from my regular trade as a communications technician . There is amazing potential for feeding the world using this system and it's environmentally friendly aside from the costs of the power which can be solar,wind or micro hydro powered depending on where you live etc .Also using compost to heat the water is another way to reduce the price for heating water and or air temperature for a greenhouse . The beauty of the system is that it can be as simple as a couple of tanks for the average person and then the plants of course or a full scale farming operation . It's all about the ambition of the person or people, cooperation and support ,their dedication and their abilities to make it work . Also your entirely right about how you can scavenge things for free or low cost .I got several of my fish tanks from 10 gallo up to 200 gallons and plastic and fiberglass ponds for the price of the gas I spent . Craigslist can be your friend if you get the jump on everyone else and most importantly follow through . Anyway excellent video, I subbed 👍

is a nice set up. Can everyone do that? Maybe as you point out, when food gets so expensive that it makes it feasible for one person to stay home and take care of the system, yes. Very few people knew about moringa until Fidel Castro claimed he ate it to fight off cancer. In the dominican Republic people were stealing leaves and whole trees from other neighbor's yard after that claim. So stupid. Many Asian countries eat insects, they too are packed with proteins.....raise insects like crickets feed them to your tilapia? good video. I know this video is almost 5 years old, are you still doing this? An update?

have you thought about a mobile 100W solar panel you can buy at an RV supply shop? condensation tanks to pull water from the air? https://www.amazon.com/LCS-100-Watt-Solar-Panel/dp/B01CHTRENM I'd have to find the video where in Africa they make these tear drop tanks for water gathering in arid places. its a tear drop frame made of bamboo or some osrt of other bendable woody stuff, then a drop sheet people use for water ponds inside then metal coils inside of that then a spout on the bottom to drain the water captured from the metal wires inside , in cali this would be good probably only in summer but here in Tucson it would be great year around mostly. I too am starting my own aqua and hydro ponic farming so am coming up with ways of doing everything off grid in case water gas electric get shut off from city. i saw the coolest 100w system that simply folded out like opening a small suitcase and it had the cable for running small things easily and quickly mostly used in rv travels for outside use when camping but can save you that 30 cent a day thing....just thinking another example https://gpelectric.com/products/120-watt-portable-solar-kit/

If the styrofoam roofing of the rafts sits in the water that supplies the plants, is it a food-grade plastic, or is there risk of carcinogens leaching from the styrofoam into the water and being absorbed into the crops sold for human consumption? If so, perhaps there is some waterproof, food-grade coating that can be applied to seal the plastic and prevent such leaching.
