Featured School Integrated Garden Construction Photos This post was whipped up by Paul Van der Werf Some time ago we posted info on one of the Primary School Integrated Gardens we built using our Earthan Beds and integrating fish to feed the soil in the beds and plants.  I have now uploaded a video of the construction photos of that school garden project. An explanation of how this garden works We started out by setting out the garden beds and fish tank we build out of aquaplate onsite. Then the digging starts.  This garden was a little more labour intensive than I would have liked but we now have a much simpler way of building these integrated aquaponic gardens. The general idea of the layout is the centre (green tank) is a 4000 litre fish tank which runs water by gravity from the fish tank to the 12 garden beds.  The smaller red rings (6) are about 1.2 m2 and the longer bean shaped cream colour beds (6) are about 6m2 each. The water runs through the garden beds and gravity back to the fish tank.  I know you are wondering how we gravity from a fish tank higher than the garden beds and then gravity feed water back from the lower garden beds to the fish tank....  I will explain that shortly. The beds themselves are lined and plumbed (all underground) for inlet and outlet water.  Then a layer of 20 to 40mm river gravel, a geo-textile fabric over
