Automated Hydroponic Systems can be divided into two basic groups: Passive and Active Systems.In most passive systems, the nutrient solution remains static and is conducted to the roots of plants, usually by capillary action or wicking. This is achieved by means of using a high capillary power culture, usually fed by a wick such as that of a lamp or oil lamp or even a basic mop thread. Within passive systems are those that use automatic irrigation systems without resorting to electricity, such as those that water by gravity action. TAll Active Systems, in one form or another, need circulation of nutrient solution through a pump, and most of them also use a parallel system to perform the aeration or oxygenation of the nutrient solution in the reservoir. There are hundreds of hydroponic systems, but any one of them is always a variation of these six or a combination of two or more thereof. What should always be taken into account in active systems is the possibility of power failures or failures of the pumps themselves and so adapt our system whenever possible.
