Growing plants in solution (hydroponics) is a technique grow plants without soil, but grow directly into a nutrient medium or a substrate that is not soil. The media can be sand, rice husk, coir husk, peat, vermiculite perlite… Often defined as “growing plants in water” or “growing plants without soil”, hydroponic technology is one of the professions. Modern gardening. The secret of this technique is to supply the plants with the necessary mineral elements at the right time. Provide adequate food, ensure enough light, CO2 for photosynthesis, O2 for the respiration process, plants can grow healthy according to the wishes of the grower. Hydroponic farming has 6 basic models.
– This hydroponic system is considered the simplest of the six models. This system has the same operating principle as the wick in a kerosene lamp, drawing oil up to maintain combustion.
Model of the wick system
REMOVEThe key to this system lies in the wick. Place one end of the suction wick so that it touches the root of the plant. The other end of the wick is submerged in the nutrient solution. This wick will do the job of absorbing water and nutrient solution to supply to the roots. This way the plant will have enough water and nutrients to grow.
– This system uses container or water containing the hydroponic solution. The pedestal that holds the plants is usually made of lightweight plastic such as porous and floats right on the nutrient solution, the roots are submerged in water containing the nutrient solution. Because the environment lacks oxygen, a pump is required to pump air into the effervescent block to provide oxygen to the roots.
Model of static hydroponic system
This type of hydroponic system is commonly used in teaching. The system is less expensive, can utilize water tanks or other stainless containers.
Unlike a static hydroponic system, a periodic flooding and withdrawing system with roots that are always submerged in water is suitable for only a small number of plants. The periodic flooding and draining system has a control pump that can pump the nutrient solution into the grow tray and draw it out at a predetermined interval. Thus, the roots will have times when they are not submerged in water to “breathe” naturally, avoiding being flooded or waterlogged. This system is often applied to aquaponics modeling.
Model of the periodic flooding and withdrawal system
– The drip hydroponic system is the most widely used type of system in the world. With this system model, the pump will pump the nutrient solution up, dripped directly into the root of the plant by periodic drip pipes. The residual nutrient solution flowing down will be recovered in the reuse tank. Thus, this system uses nutrient solution quite effectively, excess water is reused, not wasted.
This system can be used to grow herbs and flowers, fruit trees such as tomatoes, cucumbers, melons, peppers, etc.
In this system, Nutrient solution is continuously pumped into specialized hydroponic tubes and flows through the roots of the plants, then they flow back to the tank for reuse. Usually, in the nutrient film system, there is no need to use additional planting material, which saves the cost of replacing the substrate after each crop. This system is often used in large-scale commercial purposes.

Aeroponics is the highest technical form of hydroponic system.
Model of aeroponics system
Like the nutrient film system, the growing medium is mainly air. The roots are exposed to the air and misted with a nutrient solution. Misting is usually done every few minutes. Thus, the tree has enough food, enough water to drink and always has air to breathe. Currently, aeroponics is applied in the potato growing model.
Above are some basic knowledge of 6 types of hydroponic models. Hydroponic technology was born, leading one of the most advanced technologies in soilless farming, promoting productivity and continuous intensification. but not harmful to the environment.
