Hydroponic Bog Garden (Water Recycling)

Step 9 Add water

Once we have completely filled the centre section of the hydroponic bog garden we then start filling it with water and adding the rest of the sleepers around the outside of the system. This size of tank takes around 6 cubic metres of water to fill it to a level just above the Alfagrog. Filling it with water allows us to level the Alfagrog and ensure that when we add the gravel to it that it is all immersed in water.
