Diy Air Diffuser Hydroponics

You should know that each time the water comes into contact with the air, the air diffuses into the water, this phenomenon occurs when the water on the surface of a tank touches the air in a growing room or when air bubbles rise through a column of water in a tank, thing happens, there are lots of producers use the combination of an air pump and an air stone to add oxygen to their solution which consists of mixing water and fertilizer. this method is very effective viable for many producers and capable of increasing the levels of OD and for cheap, moreover, An air pump serves pumped the air through plastic aluminum tubes at the bottom of the tank where it is attached to an air stone that holds it. The air stone then diffuses the air into small bubbles which rise in the water, thus increasing the level of OD. This method aims to prevent the fertilizer from settling at the bottom of the tank.

Air Pumps & Air Stones

The most important thing is to know that the size of the bubble produced by an air stone plays a very important role, it makes an important difference in their ability to add dissolved oxygen to water. we take only one large bubble and eight small bubbles which have the same total amount of air inside, the surface of the small bubbles will always be larger, of course. By producing bubbles half the size, the surface will be doubled, doubling the surface contact of the bubbles with water and doubling the ability of air to increase the level of DO. without forgetting the fact that the small bubbles are less floating and rise more slowly in the water, which allows them to diffuse more oxygen in the water. Smaller bubbles are produced by high-quality silicon carbide air stones, which are fired at around 1300 degrees. a more porous stone that bubbles smaller than the cheaper air blue stones which are only fired at 200 degrees Celsius produced by high temperature.

Air pumps and air stones, however, are not without problems. Pumping the air inside a growing room and especially in a growing room rich in CO2, will help to lower the pH level of the fertigation solution over time, like air, for example, the area which contains 400 PPM of CO2 reacts with many elements of water like calcium, in particular, thus carbonates are formed which accumulate and which in turn lower the pH of the solution, all the more as the water retains certain gases better than others, and also because water can only contain a limited quantity of gas at a given time, in addition, the water molecules selectively retain CO2 and allow O2 to dissipate out some water. Take this example: if water can only contain 100 units of saturated gas and it starts with 50 units of CO2 and 50 units of O2, while air bubbles in the water over time, be aware that water will absorb more CO2 and release O2, which will lead to lower and lower DO levels over time, but this does not mean that All hydroponic growers will kill their plants since if we add hydrogen peroxide, it should oxidize the roots and if we did bubbling air into the water, this will raise the pH and cause the DO level to decrease over time, and even if we do nothing when the water stays still, the dissolved oxygen begins to rise from the bottom of the tank and dissipate into the atmosphere. There is, of course, a solution to these DO problems, and well this solution has added a mixing or stirring pump to the tank, and this will solve your solution.

Hydrogen peroxide 

Hydrogen peroxide is a common practice used by many hydroponic producers, but unfortunately, its practice is poorly understood. be aware that there are 2 forms of oxygen:

O2 has the diatomic form which can be absorbed by plant roots.

   O2-, the very reactive radical form. Hydrogen peroxide turns into H2O + O2- when added to water. The O2- that is formed is undesirable as it will indiscriminately oxidize or damage healthy living plant cells. in addition to this, although adding hydrogen peroxide to a tank will initially increase DO levels, these gains are short-lived. Hydrogen peroxide is best kept in a cultivator’s toolbox to clean equipment and treat bacterial and fungal infections in a practical way.


These methods already mentioned are intended to prevent people from killing their plants by slowly depriving them of the same oxygen they needed to live and of water. but this is due to their ignorance about it, he did not know what to do, but unfortunately, once the plants are dead they cannot come back to life. these methods that we talked about in this article, we aim to prevent more of these insane deaths, you understand that all plants use carbon dioxide for photosynthesis and produce oxygen as a by-product of this reaction photosynthesis. plant roots must have oxygen. In a hydroponic environment, it is essential to ensure that the roots of your plant are supplied with oxygen. Producers especially using organic soils will never worry about providing oxygen to their plants; and therein lies the problem, hydroponic growers must be well acquainted with the science of dissolved oxygen, they must be well aware of their plants and know more about them.
