In recent years, a number of farming businesses in Da Lat and its neighboring areas have turned to hydroponics, or cultivation of plants in a nutrient liquid with or without a supporting medium, in a bid to produce safe, quality greens.
Under the hydroponic model, vegetables, mostly leafy ones, are grown in nutrient-filled water pipes.
During harvests, all farmers have to do is gently pull the vegetable stems from the pipes and chop off their roots before consuming the entire stems and leaves right away, without rinsing or preliminarily processing them.
This is going on at several major farms in Da Lat City, the heart of Lam Dong Province, in the Central Highlands.
