As we know hydroponic system has many techniques to be used. Each one of them has advantages and disadvantages.
In this article, we will talk about one of the most popular techniques in hydroponics which is called continuous-flow solution culture.
What is the definition of continuous-flow solution culture technique?
Continuous flow hydroponics has a broad range of the hydroponic technique.
Generally, this method refers to a system where the nutrient solution continuously pumps over the root systems of the plants. Nutrient Film Technique is a good example of this method.
In this technique, the nutrient liquid provided for the plants constantly flows around the roots.
Continuous flow solution is a lot easier to mechanize when compared to static culture,
Since adjustments and sampling to the varying temperature level and the concentration level can be done easily in a big reservoir that feeds potentially numerous plants.
A well-known alternative of this technique is the nutrient film technique.

That is by which a very low flow of water consisting of all the essential nutrients for the plant development is re-circulated around the uncovered roots of the plant in a waterproof solid root mat.
This root mat is developed at the base of the canal and has the upper surface almost damp and suspended in the air.
Consequently, there is an ample contribution of oxygen to the plant roots.
The correct canal slope along with the correct stream speed and the correct canal length can designate a proper nutrient film technique.
The biggest advantage of nutrient film technique is that the growth of the plant is uncovered to ample supply of water, nutrients and oxygen.
Another variety of creation brings in a deficiency and a divergence among the various supplements of nutrients and the requirements of essential elements resulting in a disproportion of the whole composition.
This design structure provides a great system for strong plant development and an effective cultivation system.
The consequence of this technique brings in high yield and exceptionally nutritious crops.
However, one must remember that while applying the nutrient film technique a little negligence or carelessness in the power outrage or any other elements might result in negative impacts.

So How Does Continuous Flow Work?
With the continuous flow system, there will be a constant flow of nutrient supplementation over the roots of the plants.
One of the benefits of this method is that the reservoir of the nutrient can be made remotely from the plant, including the growing medium.
With that, a large reservoir can be utilized to serve a lot of plants. Larger hydroponic reservoir means that it can be easier to keep the pH, EC levels, and temperature as stable as possible.
It is also easier to avoid risky problems which can include sudden changes in these values.
There is also a disadvantage with the use of the continuous flow system.
When you use this method, there can be a little room when it comes to maneuvering whenever something goes wrong.

For example, if there is an overnight power outage, there is a big possibility that all your plants may die.
This negative aspect of this technique should be weighed properly against the advantages and superior productivity.
When you are able to make the dissolved nutrients be ready and available for all your plants, the roots may achieve the highest and explosive growth.
A lot of productive hydroponic systems that are available today often rely on the concept of continuous flow.
However, this still necessitates the grower in some ways, giving enough oxygen for the root systems for example.
