Vertical Hydroponic Gardens are for the people who have a shortage of space, and still need full utilization of their small space. You cannot always have large fields of space for yourself, and a hobbyist needs to make do with whatever is given to him or her. The hydroponic system gives a very high return on investment, and the space utilization is also very optimum. This is the choice for people who have the know-how and are well equipped with the materials used and the chemicals required for growing plants in such small places.
In this system, the roots are grown not in soil, but in an alternative medium, and that could range from pebbles to coconut husk, or even perlite or gravel. Sometimes, even water mist is used to provide nutrients to the roots while the plants are suspended in the air. This provides the maximum utilization when the plants are stacked vertically, and this is where the name of this system originates. The system allows for almost five times the number and volume of plants as can be planted in a plain horizontal plantation system. This creates beautiful green walls and extracts the most output. The plants live healthily too, provided the nutrients are supplied well.
The plant roots are biologically not required to grow very much, since the nutrients are provided directly to the roots, and so, spreading too much is unnecessary. And the roots do not spread much either. Since the roots do not spread, much denser collections of plants can be grown at a time, and this is the primary need of this system. The nutrition is exactly in the amount in which it is required, and this leads to a very healthy growth in plants. The composition of fruits and vegetables that are produced is thus better, and the result is a better tasting and looking harvest that sells very well. Since the plants are so closely packed, the light, temperature and air circulation also become cost consuming factors. The overall environment needs to be balanced, and this needs a lot of sensors and equipment that continuously track the changes in the environment in the area where this gardening is done. But since the per-capita harvest is very high, these costs can be offset very easily, and the equipment cost is a one-time seed investment, which can be covered very soon.
