No. Seriously. Gardening without dirt!
Hydroponics is a very effective and efficient way to garden. Essentially, hydroponics has you growing vegetables in water.
There are several advantages to hydroponics over regular gardening or farming. Hydroponic plants grow up to 50 percent faster than plants grown in soil and the yield is greater! Why? It seems that there is more oxygen available to the roots.
That increase in oxygen allows the roots to absorb nutrients faster than in the soil. This saved energy allows the plant to produce more edible material. Other benefits include less use of water, less use of artificial nutrients, no pesticides, no erosion…
This is a very unique system that allows for a great amount of production!
