Spinach (Spinacia oleracea L., cv. Okame) growth experiments were carried out to study the effect of dissolved oxygen (DO) concentration on growth in a deep hydroponic culture. Pure, pressurized, O2 and N2 gases were supplied to the hydroponic system for precise DO control. This system made it easy...
