    Hi there,

    I am currently looking at setting up an aquaponic system in my backyard in Chillawack, British Columbia, Canada. We have a few shipping containers in our yard, was thinking of using these to house and run the operation: 1) I have seen aquaponics flourish in shipping containers, tho they do need ‘grow lights’ 2) The weather in BC is unpredictable and we don’t receive much sunshine, so I believe we would need ‘grow lights’ anyways.

    Please may I get your opinion on the above scenario, as well as if feasible, can your aquaponic systems be tailored to suit this?



    1. We don’t recommend shipping containers because of the intense heat in the summer months and lack of circulations.

        Thank you for your response.

        If I were to purchase a Portable Farms system, Is there a guide on which type of greenhouse one would need, factoring in different weather conditions? This not stated in the “What the PF kit does not include.”

        Also what are the dimensions of the grow bed that is scene in the “module image” on the price sheet and is that powered by one PF system?

          Just to follow up on the comment above: what is the projected cost of the extra supplies (lumber, fish tank, batteries) , that is need edto set up a $2500 PF system.

          Is there a list (with dimensions) of all the extra’s provided with the package mentioned above?

          I am very interested in getting the system, but just curious of what the overall cost will be, if there will be a list of all the extra’s that are needed and if there will be recommended suppliers for these extra’s.

          I need this information to make a final decision. I hope you’re able to provide it.



          1. Thomas: We recommend you buy lumber, gravel, pvc in your local markets. We don’t sell or ship them. You’ll find a complete list of what is included in the Portable Farms Kit and what is NOT included in the Portable Farms Kit in our price list you can sign up to receive on every page of our 400 page website (right panel, second box). Thank you for your interest in Portable Farms.

          2. We recommend you research greenhouses to accommodate your climate. You may build a grow table to accommodate the size of your greenhouse. We teach that in our online course. How many people you feed determines the size of the grow table. A grow table that is 5’x 40′ feeds 8 people.

    i’am looking for a commercial aquaponics system to purchase.

    1. kuteesa,

      No. You have to take the AU Course unless you buy 20 Portable Farms Kits and then we train two of your people before we send you the PF Kits. No training no kits. You can install approximately 120 Grow Table Modules on one acre. The book Commercial Aquaponics GOLD covers all if the information you need to go commercial.

    Hello Phyllis Ma’am,

    I’m a student who has completed B.Sc in Food Science and Nutrition and was seriously looking to proceed further with a Horticulture degree as I was keenly drawn to Hydroponics and had even written to 4 different Institutions, when I stumbled upon Aquaponics. And, now this, fascinates me and hence, I write with the fond hope that you’ll guide me with my queries.

    1) Could I download, or, could you email me the form for the Portable Farms Aquaponics Systems Course, if that would be the right one to do, for me, or, would you kindly advise me as to which course would practically suit my purpose – of being able to grow healthy home food for my parents and family till I’m single and around, and create a permanent set-up for them that’ll enable them to live healthy, life long !??

    2) I understand the costs involved and have spoken to my dad who’ll work it out, as he has gone through the entire science in your video presentations, and is convinced of its necessity for Mankind’s future. Besides, there are other friends of his, in connected/concerned departments who’ll ensure of fastest delivery after customs clearances without the regular understandable corruption hassles, these third world countries face…

    3) Umm… A wish, maybe… But, could/does a student have the option of flying down to your country, becoming a student-resident or something, and take this course physically under your esteemed personal tutorial and guidance? Does such a set-up exist?

    I sincerely hope to hear from you at the earliest and look forward to hearing from you folks who have dedicated themselves to serving Humankind, come what bloody may!

    Regards and Namaste,

    Anusha ( from Mumbai, India )

    1. Anusha,

      Thank you for your inquiry and congratulations on your accomplishments. Serving Humankind is a worthwhile goal but it still requires funding to build, operate and distribute the food to those who need it most. It has been our experience that our aquaponics systems are most commonly used by those who want to pay top-dollar for the best food in the world and not by those who most need the food because they are expensive.

      Responses to your questions:

      1. The Aquaponics University Portable Farms Aquaponics Systems Course© covers exactly what you need for the stated purposes.

      2. The Portable Farms® Aquaponics Systems are not designed to feed poor people. They were designed to produce the finest locally grown, pesticide free food on the planet. For a family this means some capital investment and a long term commitment to operating a simple aquaponics installation. For commercial installations the initial capital cost is too high to then sell to poor people and the real market is to those who can afford the best food.

      3. No such set-up exists. The AU Course is an email correspondence course similar to the Oxford correspondence courses. You and your family can take the course at your own pace.

      We trust this information addresses your concerns.

      To answer your question: Even winning the big prize would not even be enough to pay for one quarter acre of Portable Farms®. The prize is worth only US$53,000 and a quarter acre of Portable Farms® cost US$300,000. Sorry to disappoint you, but two acres of Portable Farms® will cost approximately US$2.2million or 4Billion naria.

    The roof of my house where I hope to build my greenhouse has a 10 meters by 10 meters space available for the structure.
    I would like to know…
    What is the best type of lettuce that I can grow in the mexican weather? (I live in Cozumel island (I think its defined as tropical))
    What is the biggest amount of lettuce that I can grow in a greenhouse that would feet on my roof?
    Thank you.

    1. Yosef,

      The best type of lettuce to grow is the type the resort hotels and casinos use in their top end restaurants. Your market will dictate what you produce. The marketing survey needs to be completed so you will know exactly how much lettuce your market will buy. A Portable Farms® of that size will produce approximately 200 heads of lettuce every four to five weeks or about 1,000 lettuce per year. In the second and subsequent years your yield will go up as you become a better farmer and the system cures.

      We trust this information helps and we look forward to having you as a student of Aquaponics University, the first step in obtaining the Portable Farms® Technology.

    1. Yosef,

      The Aquaponics University Course is an email correspondences course. Once you have paid for the AU Course you begin to receive sections of the Course material by email. When you complete each set of sections you will answer the test questions and email the answers back to the University for grading. Then the next set of sections are sent to you providing you passed the quiz. The rest of the AU Course is done in this fashion until you have completed all of the material. Most of our students complete the course in about two weeks of an hour a day work. A few have completed the entire AU Course is as little as four days.

      Upon completion of the AU Course you will receive a Diploma and shortly thereafter the Portable Farms® Aquaponics Systems Technology Kit containing our patent pending components for building your own Portable Farm on your roof in Mexico. For shipping outside of the US there is an additional cost of US$121 to cover the much higher shipping cost. We add this to the tuition in the very beginning so there in no delay in you receiving your PFAS Kit.

      We trust this information helps in moving your project forward and we look forward to having you as a student.

    1. Susan,

      Welcome back. That is a wonderful size greenhouse. Depending on how the Portable Farms® Modules were laid out you could utilize up to 50% of the footprint (2,880 sq. ft) [280m2] and have over 1,400 sq ft [140m2] of actual grow space. That is a great size to begin a small commercial production facility. Please take the Aquaponics University Course as soon as possible so you can have a deep understanding of the construction and assembly of the Portable Farms® Modules and how they are operated, before you begin building. We will be delighted to help you lay out the Modules inside your building to maximally utilize the space.

      Keep us posted on your progress.

      The Portable Farms® Aquaponics Systems can be modified to use ponds IF you enclose the plant growing in screened/enclosed structures. We will be happy to work with you on this, BUT we strongly suggest that you start with a pilot project to see what the energy and operations requirements are before growing the plant side of the installation.

    1. Bill,

      The very first item on the list if your are seriously interested in commercial aquaponics or any other business is WHO IS YOUR MARKET, and be incredibly specific or don’t go in the business. What size is your market, what will they buy, how much, when and what will they pay for a year round supply of locally grown, pesticide free food? Only a person in the local area can do the marketing survey because they know their top end markets.

      Conducting the Marketing Survey defines the size and scope of your project. With a PFAS the amount of produce coming out the door is scary and it has to have a ready market or you will quickly go out of business. We trust this helps in some manner.

    We have a cistern in our back yard in Nebraska. It holds 1,000 gallons of water or more. We purchased the house in 2012 and must do something with the enormous cistern–can we use it as a fish pond and develop our aquaponic garden with it?

    1. Shawn and Michelle,

      If your cistern is underground or where there is no light, you will not be able to raise fish in it, they need some light. The PFAS is not really designed for a huge cistern fish tank. The PFAS is a modular system that uses a maximum Fish Tank size of 400 gallons. There are lots of other aquaponics systems that use large fish tanks that may be better suited to utilizing the cistern.

      Good luck with your project.

    1. Lance,

      Excellent question and because it involves the IRS you will need a ruling from them. The PFAS installation is a tangible asset that can be evaluated to establish the current value and that may satisfy the examiners.

      Personally I don’t see why not if one can put a business or property into a Self-Directed IRA then a Portable Farm should fit just fine.

    I have recently received a grant to build a Aquaponics system, roughly to a working size of 16X25. My experiment for extended food supply is for a weather, first aid response and varies other responsibilities man by one person.
    I’m also a licensed pilot so that will help with materials movement. The location is Kavik, ALaska.
    My only concern is the harsh winter temperatures. I know what I need to do, but I’m asking if you think I can run the operation on solar alone.


    1. Patricia:

      Congratulations. That’s a pretty small installation, but for one person its great.

      Your location will require grow lights and you do not have any usable sunlight for several months each year so I can’t see how solar will work. In your location you may need to have the entire setup inside an insulated building.

    I am very much interested in the training that is scheduled on May 3 to 5, 2013 in San Diego. Unfortunately, I am on-call for a jury duty that week. I am very disappointed that I will miss it. Do you have plans for another one? If so I hope it will be soon after. I will definitely attend the next one. I have a time frame in my plans. I need to take the course as soon as possible. I prefer the actual training to the on-line course.

    Thank you.


    1. Ann,

      To our surprise there was not enough interest in the May Aquaponics Class so we have postponed it. Phyllis will send you an email letter with more information and we’ll keep you on the list of those who may be interested in the future.

    Colle and Phyllis,
    I’m sure you hear this all the time, but WOW, you’re systems amaze me. I’ve been brainstorming the next business I want to get into and your website found me! I’m a Chiropractor in the chicagoland area and all things health is my passion. The organic produce industry has always been an area I’ve wanted to become involved in but never knew where to start. My plan is to schedule a tour, and then do your university training…with the end goal of a commercial system someday. I’m just curious, are there any avenues to extend the learning process after university, an short-term apprentice scenario of any sort? I look forward to hearing from you, and meeting you one day!

    In Health,

    Dr. Zac Lujan

    1. Dr. Lujan,

      You are too kind. The Aquaponics University Portable Farms Aquaponics Systems Course© is the place to start. I’ll send you the 5 Phases of Commercial Aquaponics in a separate email.

      We look forward to having you as a student and meeting you in person soon.

    Hi I have a quick question before I start my aquaponic system. I am planing on starting out with the module that comes with the AU coarse and getting started with that and then expanding into a family business as we grow and develop a market. When I wish to purchase more units are they sold by the prices on the price list or do I have to purchase them right after the completion of the AU coarse. I am looking forward to getting started. This system looks very promising. Thanks for the hard work that you put into developing this system.



    1. John,

      Once you complete the AU Course (there is a ONE DAY SALE on TODAY ONLY 3/21/2013) you can always purchase more modules. This option is listed on the Price List also.

    What is the best rock and what size rock to use in a grow bed?

    1. Richard,

      Thank you for your inquiry. The questions you are asking are proprietary information and that’s what we get paid for, our knowledge.

      Many people have successfully built aquaponics systems for years and are freely giving away their information. We have chosen to work closely with those who want to install a proven, successful system that works the moment it is completed and continues to function flawlessly for many years.

      We provide a huge amount of free information on the websites and provide a method of building or having us build a system that works out of the box.

    Congratulations on the Food Desert Grant!

    I would like to offer my services to support your program in the Raleigh, Durham, Chapel Hill area of North Carolina. I am a long time champion of creative technologies to solve the problems we have created with our mega industry society starting with building solar panels and windmills in California in the 70’s. I have most recently been working on starting a new business venture in Clayton, NC that will provide aquaponics systems in under served neighborhoods and train community members in their use.

    I have over 20 years of project management experience, understand technologies, am skilled in written and verbal communications, can organize and inspire groups and have a commanding personal presence. I look forward to talking with you soon about how I can join your team and head up your efforts in the Research Triangle area.

    I am available to discuss this further most any time except Feb 28 and 29 when I will be attending the Shared Tables local food studies conference with Will Allen in Chapel Hill.

    1. Bob,
      Please follow the instructions in the article/newsletter carefully. This means sending the information requested to , not posting it on the site.

      We do not make the selections for the positions. Portable Farms LTD is simply the focus point and will forward the resumes of qualified candidates to the funding parties.

      I trust this helps.
