A hi-tech greenhouse system imported from Israel early this year has helped meet the demand for organic vegetables on Phu Quoc island, which must transport most of its needed produce from the mainland.The 4,200sq m greenhouse, located in Cua Duong commune, includes a drip irrigation control system that allows for cultivation of up to 50 kinds of vegetables year-round.
Nguyen Minh Triet, Ecofarm director, said his company supplies 200-300kg of safe and clean vegetables for local residents a day, including water spinach, mustard leaf, spring onion and watercress.

World's first ever 'self-watering' plant discovered in Israel
Scientists have discovered the world's first 'self-watering' plant in Israel's Negev desert – one of the driest regions on earth.

The Desert Rhubarb can hold 16 times more water than its rivals and has developed a unique ability to effectively water itself in its barren habitat.
Researchers were confounded by the metre-wide plant's giant leaves, compared to its desert counterparts, whose tiny leaves stop dangerous moisture loss.
But they found the plant's large leaves are the key to its success, because they are covered in microscopic streams through which water can be channelled.
Scientists claim ridges in the leaves act like mountain valleys, funnelling the water slowly and directly into the plant while stopping it evaporating.
A team from the Department of Science Education-Biology at the University of Haifa-Oranim, in Israel, said the leaves act like a mini irrigation system.
Lead researcher Professor Gidi Ne'eman said "We know of no other plant in the deserts of the world that functions in this manner.
"We have managed to make out the 'self-irrigating' mechanism of the desert rhubarb, which enables it to harvest 16 times the amount of water than otherwise expected for a plant in this region based on the quantities of rain in the desert.
