Tour of Kratky's Hydroponic Garden in February, 2018

A tour of my hydroponic vegetable garden in Hilo, Hawaii is presented. Crops include lettuce, pak choi, watercress, tomatoes and cucumbers.
Plants were grown by non-circulating hydroponic methods and pumps, electricity and mechanical aeration devices were not used.
