In a commercial application, many hydroponic farmers
grow their crops inside of a controlled environment
greenhouse. This not only provides shelter, but also
an ideal, stress-free environment for the plant.
Because many hydroponic gardens are quite small and
very clean, they can be set up almost anywhere
indoors, on a patio or a windowsill, making it easy for
the gardener to provide shelter for the plants.
In a traditional garden, the soil anchors the plant and
provides support. In hydroponics, the growing medium helps support the plant to some extent but most
often additional support is needed. Plant stakes,  strings, 
and clips are used for this.
