– Food in <strong>Basel</strong> II – – Urban Canopy Garden –<br />
Any plant can be grown hydroponically given the right methods and techniques. The practice of growing food crops using hydroponics<br />
continues to gain popularity mainly becuase of the greater control of the crop and the potentially higher yields.<br />

Soil vs. Hydroponics: Carrot Production<br />
An annual average harvest of 19,000 t of carrots are produced on 1,400 ha in Switzerland. It would take 1/4 the land<br />
area to produce the same amount of carrots in Switzerland using hydroponic methods.<br />
