Excavate sub base, prepare a stone-free and flat-bottom cavity with vertical walls 16 inches deep, divide it in two with a divider and cover both hydroponic chambers with a pond-liner.
Connect pipes in a herring-bone pattern inside each section, and cover them with gravel.
Connect the Hydroponic chambers to each side of the basins, seal pipework correctly and water test before proceeding.
Level the gravel surface and pour 2 inches of Capillary Concrete on top. Make sure to level the Capillary technology with laser grading equipment.
Install the coarse sand growing medium as root-zone material and shape the surface as desired, allowing for a maximum of 8 inches of difference in height.
Make final adjustments to the controller and water levels in the Hydroponic chamber and seed or sprig grass to establish.
