Ooops.....didn't realize that we had left it on record sorry - we love gardening but making videos is less fun!

I am impressed by the variety of the plants. How much volume has Your fish tank ?

Interesting. Does the 5.7 m2 include the fish? Please keep us informed on how the project is progressing. In particular when the data is available, let us know how much food (fish and produce) is harvested?

How many iAVs' beds are all 176 plants split between?

You are so funny :-) Yes, the best way to compare is to truly compare, putting the two in comparison side by side. When most people do not have the time and mind set to do the comparison, we do it for them and let them see what is black and white!

There seems to be a lack of credit to the other video in this post

Hey everyone! We really encourage you to watch this video with a playful mindset. Life’s all about enjoying ourselves and spreading some positivity, especially when it comes to fun hobbies like growing your own food and staying healthy. This video is here for your entertainment, and we hope it inspires you to lighten up a bit! We’ve faced some challenges from folks in the fertilizer and aquaponics communities, and we’re genuinely hoping for a more supportive and respectful conversation moving forward. Life’s too short for negativity, right? We’ve seen enough drama in this industry to know what really matters. By the way, if you’re curious about how to make a bell siphon, just hit up the search bar and type "how to make a bell siphon"-it’s that easy! 😄 Let's keep in mind that life is short, so it may be beneficial to focus on happiness and take things a little less seriously. After all, what's the purpose of healthy and positive eating if it brings negativity and resentment into our lives?

In todays video, we learn that I can not spell!!! That's what I get for being a smartass :)

Nice Murray, great to see. Dr McMurtry did his work in Africa. We started working on returning it to Africa back in 2014, and at that stage the term Sandponics did not exist. Dr McMurtry helped us with advise and support back then, but asked us not to use the term iAVs as ours had a greater leaning towards the fish rearing. We then coined the term Afriponics. As your experiencing, the growth we also experienced was phenomenal, since then we had a coup in the country we were working in, a pandemic & shootings, but we are setting up again in Cape Town.

Go to wikipedia and learn more about iAVs or go to the iAVs.info website which is the official site for Dr. Mark McMurtry..

It´s not gonna change aquaponics. SANDPONICS will make aquaponics disappear. I am sooooo tired of all them aquaponics preachers, click hunters and Hollywood plumbers misleading people. They always throw the best away. What a waste of resources THE FISH WASTE AND THE SANDFILTER IS THE KEY > Dr. Mark R. McMurtry, PhD introduced iAVs 1980 What a tragedy. Most of his 8 year old videos have disappeared > www.youtube.com/@garydonaldson1336

Sandponics is the future of aquaponics! :-)

Is a great job

Great job!!! Thank you for all the nutritional information regarding these sprouts. Have you considered using grow bags to prevent the roots from getting into the lower sand beds?

Thanks for sharing very cool!

Wow what is inside

Beautiful garden

I'm liking the half-bottle greenhouse idea. My seedlings used to bake hard when using a gravel substrate.

It looks like an oasis, and the birds; not everyone has them singing in the background of there place of peace.

If you could start the recording while the pump is running and water is being pumped, that would be better :-)

Nice, thank you so much for posting this out! BTW, if I were there, I would jump into the pond without hesitation 🙂

There doesn't seem to be sand rifts in the IBC tanks, is this due to this doing this for water quality? Would you recommend a pool system; I might convert our pool into one since it's much more feasible than turning it into aquaponic system. What did you do to control the pool 'liner' as to not leach chemicals after years of probably being filled with chlorine. Appreciate the videos!

What type of fish is in the pool?

Thanks for the video but the videography is quite lacking--upside and sideways caption boards. Maybe you can review and edit your video before you post it?

Awesome project. Would be nicer if it was silent.

Thank you for not giving up. We need your knowledge/expertise. Why do they feel threatened by this method? No one told them to stop doing their methods. Every method has its place and others shouldn't be kept from learning all methods then choosing which one they prefer. When I finally start, I will be focusing on: sandponics/iAVS and dual root zone (using grow bags)

This is a short update to let you know why we have not uploaded a video recently... we will be back to normal content soon. You can see the full list of the iAVs Research Group at: iavs.info/the-iavs-research-group/ Here is the link to read the paper written by H. Douglas Gross, Prof. Emeritus, NCSU Office of International Programs, 1988: iavs.info/the-aqua-vegeculture-system/ If you would like to help support Dr. Mark McMurtry please visit this link: iavs.info/help-dr-mark-mcmurtry-the-visionary-behind-iavs-rebuild-his-home/

absolutely crap.... how do you pipe water around.. OMG are you a lefty... gone mad ?????

Indeed, right on. That is the question Richard and I ask when we incorporate iAVs into our design of PyraPOD. We suggest using a special pond liner that is using silicone as the final coating. So, using food grade materials to go with sand is critical.

Where is this located. The place should be made public so that we can all go and check it out. I would like to go!

I am so glad to see this. Whoever wants to stop you from sharing this is selfish and money driven. He or she will not fit the coming Jubilee! We should have seen millions of videos like this since Mark McMurtry started in the first place. So many videos on the twisted Hydroton based and Bell Siphoned aquaponics, very few on the best, original, simple, and easy to do iAVs - why? Why the almost free one gets suppressed and the money sucker ones are flying everywhere? It is the selfish and sinful nature of mankind. May God help us!!!

what is this ? i'm blown away can you build one for me, not this big but like 500-1000 sqmtr

Is this yours?

absolutely stunning, well done all round, we are presently plumbing out a system with pipework underground(concrete tiles) so seeing this system and the clean lines makes me realise again why I want no exposed pipework

Do you use pond liner in your growbed?

Nice !!!

From your experience does it reach 2 kilos per ginger in 1 year

Here is a system breakdown: Sand One of the beds uses sand that is used underneath synthetic turf, it is sized at .2mm to 1mm and is not recommended. The other bed uses a coarse sand, used for underneath pavers, it is sized at .4 to 1.2mm and is highly recommended. Water From November 2023 to June 14 2024, our daily water use was only 0.01% per day due to the fact the our grow beds were not covered, and we had fairly consistent rain over those months. pH We check it 3 times a week but after this system matured (in about 5 weeks) the pH never changes and stays at 6.4. TAN We check it 3 times a week but it has never been an issue. Fish Food We use properly formulated commercial feeds of floating pellets and feed the fish twice a day to satiation. It costs $15 a kilo (we plan on getting it in bulk to bring the cost down) Fish This system was meant to be temporary and so it ran on about 10 goldfish until April 2024 when we replaced them with 118 jade perch fingerlings. Air Pump We have an air pump with built in battery backup in case of power and/or water pump failure. It is 12 watts and it runs 24 hours per day. Water Pump Our water pump has a digital controller to set the flow rate. It currently runs at 12 watts for a total of 2 hours per day and is a DC pump so we can connect it to solar. Timer A mechanical electrical timer is used to set the irrigation schedule for the water pump. Irrigation The grow beds are irrigated for 15-20 minutes (until the sand is saturated) every 2 hours during the day, there is no irrigation at night. Each irrigation cycle should pump 25% of the volume of the fish tank. Fish Tank 1000L in a catenary shape, lined with a food safe EPDM liner. Heater We added a 50W heater for the months of June and July as it is too cold for the fish. It runs 24 hours per day. Grow Beds 2.4m x 1.2m and 30cm deep. Sloped 5 cm towards the drain. Diary We keep a diary to record our observations and track pH and TAN tests, daily temperatures, feeding rates and any other notes. Plumbing Some hoses to irrigate the water, 2 valves to set the flow rate for each bed, and a puddle flange for a drain on each bed. Costs With Australian electricity priced at about 30c a kilowatt, this system costs $3.17 per day, or $13.60 a month. We are looking for a better supplier of fish food, we are currently paying $15 a kilo, we will calculate the costs and update this soon..... Solar We are in the process of setting this up and will update with all the details when we can. Bell Syphon? No! There is no syphon at all. Extra Filtration? No! There is no extra filtration.

so your media is not sand?

Micro green harvesting is cool

Wow how did yall come up with this

What type of sand is that? Is the grow time of your plants shorter than with traditional farming methods?

Place all these grow units inside our PyraPOD, and then we have the best combo of both iAVS and SolaRoof !!!

Despite the rats, your set-up looks amazing. I had no idea a trellis of passion fruit could be made with this system.

We tried to make an instructional video that was peaceful but things got turned upside down a bit here and there...LOL...we are obviously not great at videos, but love gardening and love our family of fish - hopefully the next video will be better quality! Thanks for watching, feel free to ask any questions, I will update the video description accordingly.
