Third, the Drip System
The third is the drip system or drip system, which is a hydroponic system that is widely applied in homes that have the primary purpose of channeling a hobby.
However, this does not rule out the possibility that you want to commercialize it. The way it works is fairly simple because it doesn’t need so many equipments and is more multifunctional and effective.
He applied drops of nutrient solution to each plant root with the aim of keeping it moist and wet. The shape is very varied because it can be made depending on the creativity and innovation of each farmer or cultivator.
Fourth, the Tidal System
The fourth is a hydroponic system that provides water and oxygen to plants through pumping a reservoir that will wet the roots, or called tides.
Then the nutrients return to the reservoir, and this is called receding. The tidal cycle can be adjusted as needed.
The way it works is by inserting a pump in a liquid nutrient. Furthermore, there will be a time marker that can be set and will affect the tides. Because this will affect the pumping of water and nutrients or affect the tides.
Specifically for this system, it can be applied to hydroponics with more media that plants will obtain nutrients in the form of water and oxygen periodically. The oxygen carried by the pump is also of good quality.
But the drawback is, the costs incurred will be greater, because it requires more electricity supply.
Fifth, Deep Flow Technique (DFT) System
Next is the DFT system. That is, this system will put plant roots at a depth of about 4-6 cm. The application of this system is not much different in terms of technology personnel with other systems, which still require electricity supply.
The purpose of using electricity is to circulate water into the gutters by using a pump.
The advantage of this system is that when the electricity goes out, the nutritional requirements for plants remain available because the nutritional system is set to 6 cm. While the disadvantage is that it requires more nutritional requirements when compared to the NFT system.
In addition to these five systems, there are several more systems that continue to be developed. You might also be one of those who invented a new system. One of the most important things, choose the system that is the easiest and suits your needs and abilities.
Hydroponic Growing Media
Now, we will go into the next discussion, which is about hydroponic growing media. Starting from the characteristics to what materials you can use to become a hydroponic growing media.
The first thing we will discuss is about the characteristics of the planting media, namely:
Are easy to absorb excess water or shaft
Has a loose, fertile structure and is able to store a supply of water, which can then be distributed to plants
It does not contain NaCI or salt or its salinity is very low
The acidity level of the planting media reaches a neutral point or at least a pH between 6-7
Does not contain a type of organism that causes pests or diseases
Have at least the content of lime or potassium, as a nutrient for plants
Now, we will discuss about any forms or materials that can be used as a hydroponic agricultural growing media.
Mineral Wood or Rockwool, is a kind of foam growing media with fine fibers and has a light load.
Charcoal husk, which is a planting medium in the form of rice husks that have been burned.
Hydroton, is a growing medium derived from heated clay. This media has a stable and neutral pH.
Coconut powder or commonly referred to as cocopeat is a neutral planting medium and highly absorbent of water.
Sponge, this material can be used because it can drain the water well.
Fern roots, media whose work system and shape resemble chaff charcoal.
Hydrogel, a growing medium in the form of a colored gel that can store water well.
Expended Clay, is a growing medium derived from clay.
