. Moreover, this type of crop to use any space and material, however small,
useless they may seem. Most important is the commitment, dedication and willingness to participate for
to develop a successful project. vegetables need to grow: light, water, air, minerals and support for the roots. need to develop absorb some nutrients in
atmospheric gases (carbon dioxide) and other inorganic mineral salts present andNo land,
(in the case of hydroponics is dissolved in the water supply). These substances are transformed with the help of light energy into carbohydrates and other nutrients necessary for plants.
When plants grow in soil, the land provides the livelihood for the roots, but in
hidrpónicos crops is essential to provide other means of livelihood. On the other side must
have sufficient moisture and nutrients to keep the plant dry out and die.
Advantages of hydroponics:

Your risk does not erode the land
·
produce in places where the soil is of poor quality.
· produce vegetables in cities.
· produce flowers and ornamental plants.
