Soil-less growing Lettuce

One of the most important ingredient of an American salad is the lettuce. The lettuce industry is particularly large and many methods are used to grow this vegetable. There is a large population of consumers who for religiious reasons, only buy lettuces after it has been scrupulously examined and certified free of any insects.

Shira proposes lettuce growing by aeroponics methods, a system that permits a particularly high yield as well as no chance of any insect infestation, as demanded by consumers.

Lettuce is exceptionally low in calories and contains over 90% water. However, dark lettuce leaves are rich in folate and contain useful amounts of beta-carotene as well as vitamin C, potassium and certain phyto-chemicals (coumarins, flavonoids and lactucin) that act as a mild sedative, especially when eaten with bread.
