  1. Nello...welcome to Aquaponics Nation. Set up your own thread in the Welcome Wagon...and we'll talk more about what would be useful for growing in the tropics.
  2. Every bit of effort that you make to learn about iAVs-suitable sand, willl be a good use of your time. So, flush the death adders out of your pocket and get into the good stuff. Washed and graded filter sand is a good investment. Unlike almost everything else we own, sand is a true asset...one that grows in value over time.
  3. Working dogs are standard fixtures on every farm in Australia. Kelpies and border collies work with sheep...and the Australian blue heeler are the automatic choice for many who work with cattle. My micro-farm is tiny (just under a quarter of an acre) so I have a working dog to match. Meet Darci...my four-year old Maltese Terrier. She's our guardian dog...and the photo shows her keeping guard from the vantage point of my bed. If allowed, she would keep our place completely free of birds (for whom she has contempt) and she barks to alert us to the presence of people (whether

    Bee Motels

    Here's a bee motel that I built last year. It's a place for native bees (some of which are solitary) and other beneficial insects to live. These structures come in many shapes and sizes. This is mine.
  5. Rob Greenfield lives in Florida...where he pursues a minimalist lifestyle...including living in a tiny house that he built. He has a comprehensive Youtube channel containing all manner of interesting videos on many aspects of self-reliance. For those who live in a warmer climate...and like to spend most of their time outdoors...this type of house is very practical.
  6. Here's another vertical axis windmill that I came across during a road trip to South Australia in 2017.
  7. BD...it's on the coarse side of the iAVs recommendation...probably 1mm - 2mm. This is recycled glass sand. I recommend that anyone contemplating an iAVs build, conduct some simple tests...including a percolation rate test. That is the best way to source cheap sand that works.
  8. This is a little sandgarden that I just built so that I can propagate seedlings and cuttings. https://iavs.info/uncategorized/a-desktop-sandgarden/
  9. The story of 2020 is a textbook study of system collapse. It was the biggest international disruption since World War 2. COVID-19 taught us that what we believed about security...food security, financial security, security of health services and one's own sense of security...was an illusion. Millions died...and many lost friends and loved ones. Many that caught the virus (but survived) will experience ongoing health issues. Many more millions suffered complete financial ruin as wage earners and small to medium businesses lost their incomes. We saw food stampedes as the internation
  10. Scale has a lot to do with it. If you're building a commercial sandgarden then my strong advice would be to locate it near a source of iAVs-suitable sand. End of story. With a small-table top system containing 40 - 100 litres of sand, you can try anything without the financial consequence being too horrific. You can go somewhere that they sell washed and graded filter sand and buy it by the bag. If you're contemplating a backyard-scale system, then the question becomes one of 'how much is too much'? When you consider that the sand is virtually your entire system (mechanical
  11. The structure of APN is slowly expanding to enable it to address a broader audience. I've been freshening up the existing content and introducing some new stuff. Kellen has been upgrading the forum platform and updating our service agreements. Our moderators have kept the perimeters tidy. We're about to undergo a name change...and then it's time for us to rouse our sleeping membership and invite them to a new relationship with APN. I've decided locate my personal headquarters at APN (or whatever we call it)...and members of my two websites and both Facebook groups will be invite

    From some Bunnings stores apparently...and most seed places seem to have them now. Google for something near you.
  13. Hi Alex...are you interested in tiny houses? What other interests bring you to APN?
  14. GaryD


    Yeah...they're cute anough. A lot of people just eat them raw...and I've read of them being pickled. They might go well in an antipasto featuring cherry tomatoes, olives and cuca-melons. Once they find things to their liking, they really yield.

    We keep native bees...called sugarbag bees locally. They are stingless and much smaller than a commercial honey bee. We keep them just for their pollinating...and we try to keep the purple flowers which are said to attract them to the available nectar. While the hives can be split...and may even yield a little bit of high quality honey...you can ljust leave them alone to manage themselves.

    Extremely well. Just make sure you use a clumping variety. If you use a running species it will eventually outgrow you and become a weed.
  17. For those who may be interested in iAVs, there's a thriving iAVs Facebook group that you're welcome to join. https://www.facebook.com/groups/1318946951452383
  18. What it lacks in terms of animal welfare, it more than makes up for in freshness. Shortly after it arrives home, it will lose its mind (literally) and be on the dinner table the same day.
  19. In Australia, when someone talks about livestock transport, road trains come to mind. In Vietnam or Indonesia, it means something quite different.
  20. This is the most recent recirculating aquaculture system (RAS) that I built. It comprises a 1000-litre fish tank and four 200-litre filter modules...two radial flow filters, a static upflow filter (SUFF) and a moving bed biofilter (MBBR) The radial flow filters are designed so that, at any time, one is in service while the other is functioning as an aerobic digester. The SUFF uses static K1 media (or brush filters) and the MBBR is filled with around 100 litres of K1 bio-media. The unit can be connected to any aquaponic growing system...or it can supply nutrient-rich water f

    Anybody grown cucamelons?
  22. Any further updates, WillsC? Is your greenhouse operational?
  23. Is LETS (Local Enterprise Trading System) still operating anywhere?
  24. In recent times, I've bartered things that I've traded various items that were surplus to requirements for labour. It's been good for the fact that I've rid myself of the items and turned it into garden maintenance, construction, etc.
  25. Automatic spelling correction has made fools of us all at one time or another. My other pet peeve is some translation apps. For an indication of what I'm talking about, type something in English and then get the app to translate it into Vietnamese or Arabic (for example) and will come back as a jumbled word soup.
