As with everything else, the practice and application of a hydroponic system certainly has advantages and disadvantages. This section will discuss both. This you need to know to stock before you decide to farm with the hydroponic system.

First, we will begin to discuss the advantages. The following are some of the hydroponic advantages that we can learn, namely:

The success of plants to grow and develop more secure
Practical in doing maintenance
Use of fertilizer is more efficient (efficient)
Damaged plants are easier to replace
Does not require a lot of rough labor
The planting process has standardization
Plants will be kept clean
Production yields are more continuous and higher
The selling price of hydroponic plants is higher than non-hydroponic plants
Some plants can be cultivated out of season (which is generally done by farmers who use soil media)
The risk is small, to be affected by erosion, flooding or drought
Can be cultivated in a narrow area, such as the roof of a house or a small yard (Roidah, 2014)
Plants can grow where they shouldn’t
Next is the lack of a hydroponic system that can be taken into consideration and we anticipate when we start. The following are the shortcomings:

Expensive initial investment
Requires special expertise to weigh and mix chemicals
The availability and maintenance of hydroponic devices is quite difficult
Requires extra accuracy, this is done because the hydroponic plant nutrient levels need extra attention
In substrate culture, the capacity to hold water in the substrate media is smaller than that of the soil media, so that it will cause rapid withering of plants and serious stress.
The substrate is a hydroponic technique that provides water and nutrients in the form of droplets. Appropriate droplets are given to the root area of ​​the plant so that the plant can absorb water and nutrients directly. That’s the advantages and disadvantages.

Various Systems in Hydroponic Agriculture
Although previously we have mentioned that hydroponics is one of the agricultural systems. But there are a number of sub-systems in agriculture that we can use. We can adjust to our needs and abilities. Here are the reviews!

First, the Aeroponic System
Aeroponics comes from two words, namely aero which means air and phonic which means a way of cultivation. Thus, aeroponics is a crop cultivation system that uses water and air.

You need to know, this system is the best system in the process of growing and growing vegetables. The use of water and air can sufficiently replace the use of land.

In this system, plants are placed in a high position, so that the roots of the plants look hanging. The working principle of this system is to provide water and nutrients to plants using an evaporation or mist system.

The extraction comes from a water pump that is placed in a storage tank and sprayed using a nozzie. So that the nutrients provided will be more easily absorbed by the hanging plant roots.

Second, the System Nutrient Film Technique (NFT)
This is a new system in the hydroponic planting process in Indonesia. This system is suitable for application in infertile soils. It is also suitable to be applied in the highlands and lowlands.

The point is, this system can provide quality harvests. If distinguished from the aeroponic system, the NFT system does not lay roots on shallow water surfaces, but rather water can undergo adequate circulation and nutrient content. The roots are in water, so that their nutritional needs are always maintained.

The advantages and disadvantages of this system is in the electricity supply. Electric current that helps the movement of water is very influential. If the electricity goes out, the roots will dry quickly and lack nutrition. As for the advantages, this system can provide maximum nutrition.
