    Hello my name is jesse and I’ve actually started the process of getting a decently large scale of land about 3 acres and my main goal is to make aquaponics bigger in the state of North Carolina. Also I’ve been a cook for a very long time and want to make getting vegetables and proteins as a chef more fun of an experience. I’ve been studying aquaponics on my own for a little bit now do you have any advice as far as larger scale farms go?

    1. Jessica,

      The best place to start for larger installations is with the ebook Commercial Aquaponics GOLD. The book takes you from concept to shipping produce and includes a Business Plan Template and an Executive Summary will all the figures you will need.

      Good luck.

      Hi Jessica,
      I just moved to Carrboro NC with my wife who is attending UNC. I would be most interested in seeing your aquaponics farm when set up even if you live across the state. If its okay Colle can give you my email address.
      Thank you – Jack

      Hi Colle,
      If requested please provide my email address to Jessica.
      You have a great product and website. I sent your information to some friends who are now living in Jordan, its not a great place to grow veggies so maybe this may be a solution.


      1. Jack,

        Sounds like a plan.

    Hi there
    I have such a love for the new little JUNIOR. I also wanted to thank you for posting such clear instructions for not for profit organizations who want to use your systems. Everything you are doing and writing is the backbone for what is needed.

    I thank you.
    I have a lot of your videos on my blog and youtube pages and facebook. I send them everythere.

    1. Gina,

      Thank you for the very kind words. The requests from non-profits has been ongoing and we finally realized we giving the same information to everyone in that arena, so we wrote up the article and it has been very well received.

      Junior in on track for the unveiling and availability on 1 December 2014!

    thank you for the good works.i am in Kenya and would enthusiastically like to introduce this technology in my backyard besides growing my financial base feeding my it possible to start withe least size to generate money for the University course?if yes, what are the nitty grities?

    1. Kevin,

      There are hundreds of pages of information on our websites, use the SEARCH BOX, top right, to search the data base for what you would like to know. Taking the Aquaponics University Course is always step one to making money with the Portable Farms®. You do have to invest in acquiring the information, the technology and in increasing your own knowledge base in order to succeed. Step two is to define your market so you know how large to build your first installation. All of the steps are outlined on various places on the website. Go for it!

    You repeatedly post estimates about how much food you can grow on such-and-such size of land. My question is, how does that compare to farming the same area using conventional technology?

    1. William,

      We very carefully document our production so we have accurate data to back up our claims. You are welcome to do the work to find out what conventional technology will produce for you.

        So in a 24’x24′ space, you supply us with numbers for the modules, if it was conventional farmspace and separate fish tanks how does it compare ne?

        1. Totoro:

          PFAS LLC supplies the technology for the PFAS Modules that are housed in a climatically adapted structure. You are responsible for building the building to specification, assembling the Grow Trays and having the utilities to the building. You can use conventional farmspace and separate fish tanks, BUT it will have to be a different aquaponics system because the Portable Farms® Aquaponics Systems is not designed for those conditions.

          I trust this information helps. If you take the Aquaponics University Portable Farms Aquaponics Systems Course© you will have a much better idea of what is required, how to build the installation and how to successfully operate it to grow the finest vegetables in the world.

    Backyard question:
    Before beginning/ ordering the course, I have HOA guidances to follow
    What size greenhouse would be minimum ?

    Thank you,

    1. David,

      The minimum eve height for your greenhouse is 10′ to really be safe. That means the peak will be over 11′. You’re right, get the HOA guidelines first.

    Your site is so motivating! I’m loving those veggie pics!

    My yard is clay, so I tried building my own aquaponics setup with info found on youtube. Despite my best efforts I still feel in the dark regarding which plants work best in the system and, quite frankly, the system I built didn’t seem sustainable without a lot of attention. My heirloom lettuce wilted, so I know I’m missing something. That and the fish didn’t last long. All I have left are some window tomatoes! Unless I want to spend the next two years researching, I think I need to get your training. LOL

    I have my own (non-farming) business so my entrepeneurial spirit leads me to an interest in a small commercial setup and eventually an acre setup over time as I find the land. Would it be possible to get my feet wet with an affordable smaller area (less than 10K sqft) for something like a home based business that services local restaurants or small grocers? If I could net $10-20K part time learning the ropes, that would be fine. May be that ROI will help you identify a size that would suit me.

    Looking forward to the 5 phase info. Thanks!

    1. Duane,

      Thank you. You are too kind. We work very hard to have the insure our clients receive the very best and up to date information about aquaponics as we offer it.

      There is not much we can do to help you with the clay, but about the aquaponics, yes, we can help.

      The best place to start small and grow your own business is to start is here and here.There is also a great book you can order that we recommend on our FAQ page.

      First take the Aquaponics University Course so you have all of the information BEFORE you build your greenhouse.

      Good luck and keep us posted on your progress.

    Dear Colle,
    Hi,I admire your website because it is full of useful information but I have 2 questions:
    1- I noticed that you don’t use Hydroton as grow media but black rocks so which is better ? and what are the cons and pros?
    2-Is there a way to pay for the digital information of the course apart from the kit because shipping would be too expensive to my country?If yes what would be the cost?

    Thank you in advance

    1. Nabil,

      Thank you for the kind words.
      1- We have used almost every type of medium and have settled on crushed gravel. We prefer limestone because it buffers slightly better, but we are using granite now. Gravel is inexpensive, readily available everywhere in the world and work beautifully.
      2- No. The AU Course is only offered as a package because it is technology specific. We can ship to most countries and the PFAS Kit is only 30cm x 30cm x 30cm in size.

        Ive seen other set ups that recommend against using limestone/granite due to it decomposing & affecting pH balances. Obviously your system is ridiculously successful as is, but have you had any issues related to this or do you have a work around in place for this?


        1. Jeremy,

          You’re right, the amazing results we achieve speak for themselves. We have tried many different type of medium and have come to realize that the least expensive, locally available, thoroughly washed and graded crushed gravel is the best medium for the Portable Farms® Aquaponics Systems. We prefer limestone because it slightly buffers the acidic tendency of the fish water. River gravel works, but we don’t recommend it because it does not have the surface area of the crushed gravel. Go with the local, washed crushed gravel and you’ll get the same results, amazing.

          Good luck.

  1. Hello Colle,
    Congratulations on having a beautiful aquaponics system. We are thinking of starting a large-scale, commercial, outdoor aquaponics in Africa. With no prior knowledge on aquaponics, this is going to be one hell of a ride. I would appreciate it if you could give me some information with regards to feasibility and possible costs.
    Thank you

    1. Al-Amin,

      Thank you for your kind words. If you have investors or your own money and are willing to listen to the experts and hire good managers, your large-scale, commercial aquaponics installations can succeed in Africa. Yes, it will be a wild ride and it will be exciting while you make money, provide jobs and grow the best food available in the area of the installation. I’ll send you the 5 Phase of Commercial Aquaponics in a separate email.

      Good luck.

    Ecology and Environmental Science.
    This is to ask you to help me with the Commercial Growing (pdf. Special Report) document to present to investors and business partners.

    I am in an envied position to invest and would like your support for this new endeavor!

    I appreciate your time and thank you in advance for your quick response on this matter.
