Technology to automatically grow clean green vegetables in the city
According to Israel’s online news site Timesofisrael (TIC), startup GreenOnyx has recently successfully operated a smart urban farm to produce green superfoods. GreenOnyx’s farm is actually a “full” automated technology platform to grow clean green vegetables right in the city.
The message GreenOnyx said, they carry the mission of creating nutritious superfoods for the community. The farm is what GreenOnyx calls the first urban livestock farm to grow green “caviar” from fresh duckweed all year round and at an affordable price.
GreenOnyx’s technology platform is a fully automated and sterile artificial intelligence (AI) based cloud algorithm that uses advanced farming methods to biologically simulate natural habitat conditions nature in the cultivation of nutrient-rich crops, from A to Z; Slowly stitch the seed to the menu product on the plate. By using proprietary technology, GreenOnyx has grown green lentils year-round under completely sterile conditions without any human intervention, without any farmland and without worry. about weather conditions.

The startup’s co-founder and CEO, Dr Tsipi Shoham, a veteran cancer researcher a decade ago, began his quest to find the healthiest vegetables with a passion. believes that adopting a healthy and balanced daily diet is essential for strengthening the immune system and reducing the risk of diseases.
Fresh duckweed is rich in vitamins, mineral and pollution free
In the wilds of Thailand, Shoham discovered wolffia arrhiza, a tiny aquatic vegetable known as duckweed, with high nutritional value. In addition to Thailand, in Southeast Asian countries such as Vietnam, Laos and Myanmar, this type of duckweed is also available. In addition to duckweed, there is also a water-based lentil plant, which looks like green couscous or caviar, floating in ponds and growing in complex environmental conditions that also have high nutritional value. In Southeast Asia, people often wash with warm water, then cook, but doing so unintentionally loses many beneficial nutrients.
“My main expertise in the field of cancer research, it helped me realize the importance of healthy, fresh greens in promoting cell strength, preventing disease and prolonging life. Realizing the enormous health impact of the phytonutrients found in green vegetables, as well as the significant challenges, I changed my mission from innovative cancer research to breakthrough in cancer prevention. supply and consume fresh green vegetables,” said Dr. Tsipi Shoham.
The Tel Aviv-based modular, self-contained urban farm facility, which looks like a data center with a computer cabinet, can produce 40 tons of tiny green seeds a year, which the startup calls Wanna Greens (fresh duckweed). The green superfood comes in pint-sized packs (0.57 litres), is mild in taste and can be mixed with any dish or drink. They are richer in vitamins, minerals, antioxidants and other important phytonutrients than green leafy vegetables currently on the market because they are not polluted or industrialized.
According to GreenOnyx, Wanna Greens have a shelf life of six weeks, provide more iron than spinach, contain more zinc than broccoli or kale, and have more potassium than any other green vegetable. Soon, the first batch of GreenOnyx’s Wanna Greens weighing 200 grams will be sold online for NIS 22 (US$6.4 or VND 150,000), after that, the official selling price will be US$30/kg (about VND 700,000). ).
GreenOnyx hopes to revolutionize agriculture, food production in urban areas by providing fresh, clean, healthy and sustainable food right from the habitat to the table and then, combine unique technology to create sustainable agriculture to satisfy people’s requirements for food and health in the context of a rapidly growing population.
Economic value of duckweed?
According to the news site Niengiam-nongnghiep.vn of the Ministry of Information and Communications, duckweed has a small size of 0.3 – 1cm, brown when young, green when grown. This type of water hyacinth reproduces asexually by budding, has relatively small roots, 0.2-0.5cm in size, 0.3mm-sized flowers including 2 stamens and 1 pistil.
If duckweed is raised in an environment where the water is too clean, the water is too deep, it cannot develop due to its short roots, and it is difficult to find a food source. In addition, extreme weather also slows the growth of duckweed. Therefore, it should be raised in shallow ponds, only about 40 – 50 cm. Then every week, fertilize it with about a shovel of cow, buffalo, chicken, and pig manure to be nutritious enough for the ducks to eat.
The duckweed has enough nutrition, the wings are very big and thick, with many leaves. On the contrary, there are no nutrients, when picked up, it will be all roots, the wings are very thin but yellow again. In addition, raising duckweed depends on the purpose such as feeding snails, feeding fish, feeding ducks, etc., and fertilize duckweed with different levels of manure. Any fertilizer is fine as long as the organic manure of buffalo – cow – pig – chicken, organic matter is important and we let it have a source of manure that will keep for a long time. Animal manure can be fed to ducks rich in organic matter. This is an easy-to-use, easy-to-find food source. There is another way if you do not use manure, which is to pick up the water hyacinth and dry it. Then put in the tank, pump the soaking water, they will also expand, creating a source of organic matter and humus.
Second, the place where duckweed should be kept away from the wind, because heavy rain or strong wind or strong wind gathers in a corner, causing them to pile up and rot. Therefore, it should be divided into compartments one by one for easy control. In the hot summer, it is advisable to arrange the cover at the top to keep the ducks cool. Particularly in the cold season, it also needs dew or monsoon to protect duckweed.
