Hydroponic gardening techniques
If you want to grow terrestrial plants without the need of soil then you should go for hydroponic gardening technique. In hydroponic gardening techniques the essential mineral nutrients are supplied to the plant artificially. Basically, there are two techniques for hydroponic growing, namely, medium culture and solution culture.
In medium culture technique a solid medium such as rock wool, gravel or sand is used to nourish the roots of the plant. Medium culture technique may be divided into top irrigation and sub-irrigation methods.
Solution culture the nutrients are supplied only by use of nutrient solution without any solid medium. Aeroponics, static solution culture and continuous flow solution culture are the sub-types of solution culture that can be used to nourish the terrestrial plants.
Hydroponic growing technique requires a reservoir from where the nutrient solution can be absorbed by the plant. Gone are the days when reservoir material was confined to plastic only. You can easily find reservoirs made of wood, metals, glass and even concrete.
