How Nutrient Layer Technique (NLT) Is Making Hydroponics World Better

It is easy to say. NLT

is considered the most famous variety of hydroponics. In it, the pump does not work in conjunction with a timer, which greatly simplifies the process. A liquid falling into an inclined container with plants under the influence of the laws of physics flows independently from one end to the other. On the way it follows, the tips of the root system are placed, constantly receiving moisture and fertilizing. Once at the opposite end of the container, the solution flows back into the tank, from where it is redirected by the pump to the container with plants. The cycle closes on this.

The substrate in this system is rarely used. Representatives of the flora are fixed in compact pots, at the bottom of which there are holes for the unhindered exit of roots beyond their

limits. The moist air that forms above the flowing nutrient fluid fully saturates the roots of the flora with oxygen, which positively affects the growth rate of the aerial part.

The lack of substrate allows the gardener to save money and effort with each planting of new plants. The main disadvantage of the system is a strong dependence on the pump. If it breaks or the power goes out, the roots will begin to dry out very quickly. This is mainly due to the absence of any substrate.

Benefits:

• The root system receives a copious amount of oxygen, which is enough in excess;

• Effective use of free space and compactness of the installation, which can fit perfectly into the interior of a small room.

Disadvantages:

• There is a chance of clogging, so regular preventative cleaning will become a routine;

• Any breakdown of the pump or lack of electricity will quickly nullify all the difficulties if you do not notice the problem in time.
