Aquaponics – the Automated Ubergarden of the Future

tamaterAn Introduction from MMM:

I was late to the party in learning about aquaponics, but it made a big impression on me when I toured a massively creative food facility two years ago.  

The slightly wild entrepreneurial founder had converted some cheap, remote industrial buildings in Loveland, Colorado into a spectacularly productive indoor farm. Expensive herbs, heirloom tomatoes and fluffy fish were popping out at high speed, with (mostly solar) energy and sparse human labor as the only inputs. With over 40% of the Earth’s land area already converted to farms, I was excited by the idea that someday we may be able to get much more food out of much less land with a lower input of oil and chemicals.

This kicked off a bit of an aquaponics reading binge on my part. And quite coincidentally, a reader named Jeremiah wrote to me towards the end of it to tell me about his own inventions in the field. I was impressed, because he has combined the art and science of Aquaponics with a Mustachian ethos of time and money efficiency. According to Jeremiah, you don’t need to be an advanced entrepreneur or scientist to build up a fancy food factory of your own.

So we collaborated over the past four months to create something worthy of sharing with you. And by “collaboration”, I mean I made the unrealistic demand of a “Zero to Hero” lesson in Aquaponics that would culminate in something readers could actually build, and Mr. Robinson diligently cranked it out with a summer of design and documentation. I am thankful for his generous work on your behalf, and I hope this great article he wrote becomes a primary source on the Internet for learning about the craft. It’s a great read.

High-Tech Gardening and the Kick-Ass ROI
by Jeremiah Robinson

MoneyGroceriesA new gardening technique is about to save you a crap-ton of money on your food bills.

Can you guess what it is?

I’ll give you a hint.

It was invented separately in ancient times by some badass farmers in both China and the Amazon.

In China, it allowed subsistence farmers to survive on plots of mountainside land that no traditional farmer could ever survive on.

It helped the indigenous residents of ancient Bolivia and others the power to develop a wealthy and sophistocated agricultural civilization atop worthless soil for 1000 years.

For the past 2 millenia, these farmers quietly developed the most efficient and sustainable method of growing food known to man.  And nobody noticed.

Rediscovered

Nobody, that is, till 40 years ago the New Alchemists and others put 2 and 2 together.  Their modern methods, combined with the ancient techniques, got rid of most of the work associated with traditional growing (eg. weeding, watering, mulching, soil building, etc…), allowing for much higher production output at a much higher quality.

This ancient-turned-modern method of growing is called aquaponics.

It combines the raising of fish (aquaculture) with the growing of plants in nutrient-rich water (hydroponics).  The fish fertilize the plants, and the plants clean the water.

Hotter than Carhartt, aquaponics is beginning to revolutionize the world of home-grown healthy food.

DesertPonicsNow it’s much easier to grow your own safe, local, healthy food yourself in your own backyard, roof, balcony, or basement.

It doesn’t matter where you live.  It works in the desert.  It works in the tropics.  You can do it urban or rural.  I live in Wisconsin where the polar vortex gave us -25°F (-32°C), and it works here all winter long (actually improves the taste).

For the Zero-to-Hero system I’ll describe later, you just need an area that’s 5′ wide by 14′ long, exposure to either the sun or some fluorescent lights, and a weekend to build it.  To make a smaller system, you just use smaller parts.

The Math

SpinachThe ROI (return on investment) on this thing will kick Warren Buffet’s ass.

I haven’t run the Zero-to-Hero (Z-H) system long enough for good measured data on its output, so I’ll tell you about the larger system I use.  The Z-H system should give proportional results until you decide to upgrade.

My 8’x16′ aquaponics greenhouse (which is about 2x larger than the Z-H system) cost me $3,000 to build, soup-to-nuts.  In one year my system can grow the following fish and better-than-organic produce (local farmers’ market prices in parenthesis):

  • TroutPrices50 lbs of fresh trout fillets ($15/lb)
  • 100 lbs of fresh, cold-finished, food-purged tilapia fillets (Not sold anywhere.  If they were, $10/lb?)
  • Basil Prices75 lbs of pristine basil leaves for pesto ($20/lb)
  • 50 lbs of winter spinach ($5/lb)
  • 40 lbs of fresh unwashed lettuce ($4/lb)

Add all this up and I get a yearly gross output of $3,660, not to mention eating like Louis the XIV.

Here are my yearly costs:

  • Electricity ($0.20/kWh) – $200
  • Fish Feed ($40/bag) – $400
  • 7-8″ Tilapia ($3/fish) – $300
  • 7-8″ Trout ($2/fish) – $100
  • Water ($2.80/1,000 gal) – $15
  • Seeds (prices vary) – $15

Add these up and you’re looking at $1,030/yr.

As a good Mustachian who goes shopping with your middle finger, let’s say that somehow you find a way to pay half the farmers’ market price, or $1,830/yr. Subtracting out the $1,030, you still bank $790, for a simple ROI of 27% or a four-year simple payback, which is very good.

The Z-H system is ¼ the price for ½ the size, so your ROI would be even better.

Objections

System BuildBut, you object, the missing element in my budget is obvious: labor.  So true!  I haven’t included it for three very good reasons:

  1. Building it is fun: With good instructions and ideally with the help of good friends, building an aquaponic system is one of the most fun projects you’ll ever do.  It’s the sort of thing I hope to fill my time with after I quit the rat race.  As MMM says, hard work can be joy-filled and life-giving, especially in small doses.  This past weekend I built a Zero-to-Hero system with a group of 10 people in a few hours at a permaculture workshop.  I’ve rarely had such an enjoyable time!
  2. Checking on my fish is the best part of my day: I love checking on my greenhouse, feeding my fish, and harvesting food, especially when the neighbor kids come and help. You’d have to pay me not to do it.
  3. Nearly zero ongoing labor: This is especially true compared to soil gardening.  Unless you make some dumbass mistakes that you have to fix (which happens while you’re still learning how it works), the only time is daily feeding (5 minutes), weekly water testing (5 minutes), monthly planting (2 hours), twice/year runs to the fish hatchery (3 hours), and harvesting whenever you want to (5-20 minutes—you don’t have to clean your veggies, but you do have to clean your fish).

Another objection you might raise is that you want to visit your long-lost relatives in Azerbaijan, or attend the MMM gathering in Ecuador.  Don’t you have to be home every day to feed your fish, or at least every week to check your water?

Actually, you don’t.

Fish routinely go for 3 to 5 months without eating.  In my area, they do it every winter.  They survive these fluctuations just fine, if a little leaner by the end.  With no food in the system, the water chemistry remains stable as the plants slowly absorb all the excess fertilizer.  So go ahead.  Throw some basil or spinach seedlings in the system and come back in 3 months to full grown plants.  If you want, find a neighbor kid and teach them to how to throw some food in the tank and use the water test kit once per week.

I monitor my system online using an Arduino controller along with Xively.  Incorporate Zapier and you’ll get a text message when there’s a problem.

It’s high-tech, low-maintenance gardening.

The Zero-to-Hero Aquaponic System

SystemDiagramThe Zero-to-Hero system offers you a simple jumping-off point if you’re interested in this kind of growing.  You can buy all the products in an afternoon for about $730, build it in a weekend, and grow a significant portion of the fresh greens and herbs that a family or a frat house can eat.

It will allow you to grow year-round in USDA zone 7 or warmer.  To grow in winter in colder climates (like I do) you’ll need to make some additional improvements, such as a small hoop house to store it in. You can also shut down for the winter, and harvest your fish in October.

While you probably won’t see the kinds of outputs described above in year one, you will see them as you learn to operate your system better, which fish you can find locally, and what plants you eat the most of.

It’s difficult to exaggerate how convenient it is to have mostly maintenance-free and exceptionally fresh / tasty food right at your doorstep.

However, one point worth emphasizing is that while aquaponics is very easy and labor-free to manage once you’ve got it working, the process of making it work is a learning curve. It will take about a year and result in some dead fish, dead plants, and problems you’ve got to solve.  I’ve never met anyone for whom it didn’t, though I’ve also never met an aquapon for whom solving these problems was beyond their reach.

On these occasions, your best resources are the online forums, which are full of helpful people eager to answer your questions.  After that (or if you don’t have time) you can contact most any aquaponics instructor or product seller and they will help you for a reasonable fee.  There are also a number of books that can help you on your journey as well.

Growing this way is a lot of fun, and can be habit-forming—in a good way.

Aquaponic Farming

Some of you might be thinking the following thought:

If this works so great on the small scale, I’m going to cash out of my bank account, scale up, and start farming!

CommercialFarmIf this is you, I offer this caution: Aquaponic farming is still farming.  Nobody gets rich off it.  If you have the unique combination of skills to make it work it can be profitable.  But you still have to plant, harvest, market, transport, and sell your products, as well as manage employees.  This is hard, challenging, sometimes unrewarding work.  Many aquaponic farms go out of business after a few years.

Because the USDA is behind on their regulations regarding fish, organic certification is hard to get for aquaponic vegetables and nearly impossible for fish, even though any unhealthy fertilizer, pesticide, herbicide, or fungicide (even those used on organic farms) would immediately kill all your fish.  This means you have to convince your customers that your products carry a higher value than conventional produce and fish from China, in most cases without organic certification.  This is more difficult than you might think.

Many aquaponic farmers live off grants and free intern labor, while a few market brilliantly and make a profit selling to high-end restaurants and grocers.  If you’re interested in growing commercially, I recommend you do the following:

  • First, build the zero-to-hero system, operate that for a while, read all you can on aquaculture, horticulture, and greenhouse design, visit some farms, and start getting involved in forums.
  • Next, scale up your backyard greenhouse system, trying new designs and keeping up the research and experimentation.
  • Once that’s running smoothly for a couple of years, contact Nelson & PadePentair Aquatic EcosystemsFriendly Aquaponics, and Green Acre Aquaponics, and ask if there are any farms you could contact to inquire about an apprenticeship.
  • Also, make sure you find some farmers that have gone out of business and talk to them about what went wrong, asking them if they think your plans can work when theirs didn’t.

It can be done.  Maybe you’re the one to do it.

Aquaponic Investments

FairOaksThere are a number of existing farms out there that would be happy to accept investment funding to expand their operations.  It will take you a lot of due diligence to ensure that their farm is profitable and likely to remain so because – as I’ve said before – farming is tough!

One interesting investment opportunity I stumbled across this year is Fair Oaks Farms in Indiana, a combination farm and tourist destination with a fascinating ownership structure. They are getting a lot of people interested in farming, which is a good thing as most farmers these days are late-middle-age or older. Currently expanding into aquaculture, they are likely to include aquaponics in the next couple of years. Give them a call to talk about investment opportunities if you’d like to invest in this space.

Aquaponic Produce

ASCMagIf you’re not the farming type, aren’t looking for new investments, and can’t find a weekend (or the space) to build a Z-H system, you can still take advantage of aquaponic produce and fish.

Because you and I know that it’s better-than-organic while not actually certified, we can get the high-quality food for a cheaper price.

While there’s no directory of aquaponic farms, you can google “aquaponic farm” in your area and find out where they sell, or if they sell direct.

Give it a shot.  Once you go aquaponic you’ll never go back.

    I’m totally amped about the timing of this article. I’m a mustachian trying to get a small business off the ground (www.smartbarn.co) doing remote wireless monitoring and controls, and I was just thinking the other day, “I wonder if aquaponics needs sensors” and now i’m totally going to build my own aquaponics garden to try it out. But also if MMM or anyone else (Jeremiah/Frostyfish?) wants to eval my sensors for their projects I might be convinced to give you some for FREE. We can sense temperature, humidity, light levels all remotely but I’d love to try things like pH, dissolved gasses, anything you need. I will be emailing frostyfish and MMM too cause i’m all excited about this now.

      There’s a gap in the electronics world at the moment, between expensive and inflexible turnkey controls and start-from-scratch Arduino / RaspberryPI solutions. A modular kit that had all the components in a bag, along with instructions on how to assemble & program them might find a niche.

      I’d be happy to work with you on this.

        Hey Jeremiah,

        I have a complete touchscreen environmental sensor and control which is highly flexible. it’s based on the BeagleBoard black (similar to Raspberry Pi) and a fully completed single unit costs about $200.

        Hit me up and I can send you a sample or work with you for a custom design, pro bono since you’re mustacian :)

      Hey Andrew,

      What a great name! ;) The type of sensors I think aquaponics will eventually need (beyond the ones you mentioned) is nitrate, nitrite, and ammonia sensors that don’t cost an arm and a leg. Do you think that can be done affordably?

      Reply
      • AndrewK October 24, 2014, 9:03 am

        That’s gonna get confusing, I think I’ll use Andrew K :-)

        As far as I can tell actual sensors for ammonia, nitrate, nitrite are pretty pricey and run in the $100 range. There is another way though using color changing chips and a cheap spectrophotometer connected to the web. I just googled and found a cool commercial product called Seneye (http://www.seneye.com/) that does this. You have to spend around $150 to get started and then around $12/mo for the consumables. It does temperature, ph, ammonia, and light level but not nitrate and nitrite.

        • Jeremiah October 26, 2014, 9:00 am

          You know, one a system is up and stable those items (other than temperature) aren’t something you need to check that often. Electronic sensors for nitrogen are less accurate than the dropper tests anyhow. That’s why many large commercial setups still use dropper tests.

          The thing that’s the most urgent to know about from a distance (i.e. get notifications) is dissolved oxygen (DO). That’s caused at least 75% of my fish kills.

    Long time lurker here…first time poster. I’ve ran an aquaponics system for 1.5 years in my basement. Word of warning…energy costs will eat you alive if you have to run lights to fuel your veggies. It is not worth it unless you harness the power of the sun. After becoming a mustachian, I ran the numbers and eliminated my aquaponics system. My energy costs dropped significantly. I do plan on building it outside eventually.

    Other than that, aquaponics rocks! I’m glad to see my favorite blog promoting this!

    • Jeremiah October 23, 2014, 9:18 pm

      Spot on Jake. Great comment. The “kick-ass ROI” can become a money-sucking vampire if you try and do it indoors with lights. This is especially true for fruiting veg like tomatoes. I say “can” because it is possible to grow a small number of lettuce and herbs with a few small fluorescent lights in your kitchen, though hydroponics is much simpler than aquaponics in this situation.

      Outdoors in winter, you still need a couple hours of supplemental fluorescent lighting at sunset if you want to grow when the days are short, but it’s nothing like those 1000 watt stadium lights that folks use indoors.

      Reply
      • Jake October 28, 2014, 12:54 pm

        The species of fish you pick can also have an impact on your ROI. It is important to pick fish that can withstand your climate otherwise you are going to pay energy costs to heat the water in winter. That was another mistake I made.

        Reply
        • Jeremiah October 28, 2014, 5:58 pm

          Great point Jake! To take it one step further, you should include in your ROI calc a variety of fish stocking sizes. If you get big enough stock of a fast-growth fish, you can grow out in 6 months and switch seasonally. Of course larger stock are more expensive so you should do the calc. based on your local costs.

    Can we use PEX pipes with this aquaponics system? Other than basic washer replacements for my faucets, this would be my first real experience with plumbing, and I’d like to start off with Pex, since MMM makes it look less accident prone than I figure regular plumbing is.

    Thank you for the deal! I’ve been on again, off again interested in hydro and then aquaponics, and your plans are the wake up call I needed.

    Reply
    • Jeremiah October 26, 2014, 8:05 pm

      I’m sorry but you can’t use PEX for this setup. It would be awesome if you could, but here are three reasons it won’t work.

      1) The Uniseals are designed to accept that specific size and rigidity of PVC pipe.
      2) PEX fittings are narrower than the tubing, which makes a place that solids can build up into a clog.
      3) The minimum tubing size you should ever use in aquaponics is 1″, and 1″ PEX tubing and fittings are expensive and can be hard to find.

      I’ve done a lot of plumbing over the years, and you’re absolutely right that PEX is loads easier to use than any other kind of supply pipe. However, for this application I think you’ll find that PVC is quite reasonable as well. Just remember to measure twice, cut once, and dry fit before you glue. You’ll be fine :)

      Reply

      Gosh. That’s a stumper. For your circumstances I don’t think aquaponics is a good fit. Too much water. Hydroponics would be better. You could put the solution in a water-sealed container and shut off the pump when you’re driving.

      • Michelle October 26, 2014, 10:16 pm

        Thank you for your reply. I love fish and was hoping that we could factor that in. Not only is the water heavy, but it can splash and contribute to humidity. I will focus my research on hydroponics especially if I can have it in a water-sealed container. I saw some planting system using gutters that may work for us.

    We are just about to start an allotment. Not sure what you call an allotment in the US, but it’s a small patch of land you rent (for a nominal sum, say £20 per year) to grow your own fruit and veg on in the UK.

    This might be the perfect route forward.

    Obviously an interesting past-time for the gadget happy. Let’s see, if a million people did this at $3000 a piece, that would be an outlay of three billion dollars. Since aquaponics uses a lot of petro derived plastics (pond liner, piping, pumps, greenhouse skin, and so on), that three billion is yet another environmental load on Earth’s resources.

    A better and longer lasting use of three billion dollars would be to use it as seed money to start cleaning up the Gulf — especially the dead zone south of New Orleans. Once that aqua environment is restored we would have fisheries that would be self-stocking, self-feeding, self-energizing (wind & sun). The Gulf could then provide all our needs in fish, shrimp, lobster, clams, oysters, plant life — both seaweed and shore based plants.

    Anyone familiar with the Gulf side of Florida knows of the vast shell mounds left by the First Americans. Living was easy and food was plentiful before 1492

      Hey phred.

      The ZH system is $730, actually. So if a million did this it would be $730 million. Still a lot, to be sure, though it would also offset a whole lot of food miles. The oil inputs of pond liner, etc… aren’t all that much compared to, say, a 45 minute drive to work in your car.

      The advantage to something like this is that it gets people involved and thinking about our food system. In my experience that tends to lead people to more educated choices. Long-term it also leads to money savings, which folks could stash in Vanguard and eventually donate to a worthy cause like the one you mentioned.

    Very cool, MMM is starting to remind me of one of my favorite magazines: Mother Earth News. For anyone with an inkling for gardening or small-scale farming, they cover lots of DIY methods and topics (such as seed varieties, chicken breeds, etc.).

    I’d love to try aquaponics some day, but I don’t have a year of fiddling time to get it working right now. What I did build is a gutter garden, which I recommend as a simple way to raise food at home. Google “gutter garden” for images, but the basic idea is that plants live in pots placed in a gutter, and a pump on a timer runs water 2-3 times a day through the gutter and back to a barrel. The plants soak up water, so all you need to do is top off the barrel once or twice a week and add a bit of liquid fertilizer. I built mine out of 4 plastic gutters and wood from 2 pallets that I disassembled (get good ones), but it would be easier using long 2×6’s. Some people hang them on a wall or fence, but I built what looks like very long saw horses, the length of the gutters, with one gutter on each side (I have 2 of these supports, so 4 gutters of 10-12 feet each). For the barrel, I bought an oak half whiskey barrel from Home Depot, along with a small fountain pump and some black plastic tubing, elbows, and tees. Total cost $150 and it’s been running fine for 2 years and growing tons of salad and herbs to eat.

    Aquaponics is on my long term to do list, however I’m running a 16 site hydroponic system on my patio for much less operating / build cost. My hydroponic nutrient cost for a year is about $80-$100, and I incur minimal electricity costs to run the drain and fill pumps and an air pump in the reservoir. System build cost was about $500, but there are potential costs saving measures, including finding food grade buckets from a local restaurant for free. The system is almost entirely automated, requiring checking water and adding nutrients about once per week, and the yield with hydroponics is very high. ROI may suffer since fish is a big money item in the calculation but combine a patio system with a pressure canner and some hard work and you can have fresh vegetables all summer and canned vegetables for the winter.

    I have some pictures of the system here if anyone is interested:

    not much detail on the design there, but I’d be happy to discuss further with anyone that’s interested.

    The main attraction of aquaponics to me is getting away from dependence on fertilizer companies to run the system. In my internet travels I came across this family who turned an old in ground pool into a closed loop food factory. That would be the ultimate end goal for me. Link to the article is here:

    I am a newbie just getting my peach fuzz going but I have a ton of ideas! Soon I plan to move to barrow Alaska for work in the hospital up there and I have a question. Nobody grows food up there and I am interested in giving it the old college try since I will probably be there for several years and there are no local farms that far North. Temperatures in the arctic circle are routinely negative numbers and summer only lasts about 2 months but the sun is up the whole time. Do you think a system like this could possibly work in that climate ?

      Hey Pamela. It could work, especially in the sunny season. In the winter you’d need lights to grow anything. Might as well just put it in the garage or basement at that point. For plant selection, check out “The Northlands Winter Greenhouse Manual.” Good luck!

    Now thats its been almost 2 years since this article, could there be an update as to how the Z-H system has preformed?

      Hi Jennie. I’d love to hear the answer to that myself :) I’ve interacted with enough people that I have to think that someone’s built and run one for at least a year now, but I haven’t heard back. Anyone?

      I still haven’t run the ZH system through a full season. I have no reason to think that the results would be different than the system I have run though. The heat transfer conditions are actually a little bit better with the ZH system.

    Hey, just wondering if you’d be open to fixing the images on this post! It looks like they’re available through Archive.org, and I can either find or create a script to get the images and update your html, assuming you have the rights to use them from Jeremiah or whoever. Email me back!

      Thanks Nolan, I have emailed Jeremiah to see if we can get copies of the images and such to resurrect this article.

        Frosty Fish is back up. Apparently the issue was a PHP versioning issue that crashed Google Analytics. Thanks for the heads up!

    I’m building my first aquaponics system and stumbled on your site. Very informative. Thanks

    I would be interested in an update. What happened to your aquaponic system, do you still use it?

      Hi Monkeyboy. Good question.

      Actually my wife and I had a kid two years ago and I found that the time when I really enjoyed working on the AP system became less enjoyable. So I’ve shut it down until my daughter becomes old enough to become interested and childcare becomes less all-consuming-0f-my-free-time. I loved gardening that way, and I’m sure I’ll love it again when life becomes a bit more sane.

      In other news, I did build a farm-scale system last year, which you can see here. https://www.youtube.com/watch?v=dZ94uP5gP5k. It’s not running anymore (business partnership issues), but was really fun to build.

    Fascinating. I just pinged an aquaponic farm in my area to see if I can have a look. FYI – the photos on this page aren’t working. – Kerry
