The containers are filled with nutrient solution up to the level that covers the bottom 1/3 of the net pot
A simple premixed nutrient solution can be purchased online or at your local garden or hydroponics center.
Stock solutions of Calcium Nitrate and Chem-grow can also be mixed and added each time for a more fine tuned approach to growing specific plants such a greens vs fruiting tomatoes.
Copper tape is added to the container to prevent slugs and snails from reaching the plants
Many different types of media can be used. I used rock wool rooting cubes in half and a standard soil-less hydroponic mix of peat, pearlite, coco coir, and vermiculite in the other half.
