A hydroponicum is a farm, garden, or building devoted to soilless cultivation or hydroponics. The term has been applied to dedicated structures that provide a controlled environment for protected cultivation of plants in nutrient solutions rather than in soil, typically incorporating temperature, humidity, and lighting controls alongside fertigation systems. One of the best-known examples is The Hydroponicum at Achiltibuie in northwest Scotland, opened in 1986, which operated as a visitor attraction and demonstration facility for soilless cultivation in a northern maritime climate until its closure in the 2010s.
