Top 6 Best Air Pump for Hydroponics in 2019 – Reviews and Top Picks

Hydroponics is the art of growing plants without soil. And, yes it is possible to grow plants without soil as long as you supply all the essentials. Controlling and maintaining the water reservoir is the most challenging part in hydroponics gardening for both the experienced and the beginners. Since plants are grown without soil, the roots are submerged in a nutrient solution. By itself this is sufficient but most people forget that plants need oxygen as well. To supply oxygen to the nutrient solution you need an air pump. Deciding on the best is not always an easy task, in this post; we have reviewed 6 of the best air pump for hydroponics and also provided a checklist of the factors you should consider.

The essence of air pumps in a hydroponics system

The lack of soil is replaced by water. Most people new to hydroponics are not aware of the essence of air pumps. Most of them will only settle for water pumps and a balanced nutrient reservoir.

The water pumps only pump water to the system but there lack an essential component; air! Air is essential in any hydroponic system. Stagnant water is a good harboring place for bacteria and pathogens that might attack the roots of the plants. For this reason, you need a water pump, there is no way the system can operate without one if you want high yields from your plants.

The essence of oxygen in a hydroponic system

From basic third grade science, plants take in carbon dioxide in and excrete oxygen in a process known as photosynthesis whereas animals use oxygen and exhale carbon dioxide.

In photosynthesis, plants use carbon dioxide, nutrients, and sunlight in the presence of chlorophyll to make glucose molecule. The glucose made is the running unit of the plant but; how is it broken down?

Basically, plants carry our two processes: respiration and photosynthesis which are the reverse of each other. In respiration, plants use oxygen and excrete carbon dioxide through the tiny opening in the leaves (stomata). The oxygen is used to breakdown glucose into energy that is then used within the plants to carry out its functions. Plants need the energy to transport water and nutrients through the stem to other organs. This cannot be achieved without the presence of oxygen.

Why use the best air pump for hydroponics to supply oxygen?

For plants grown in the soil, the soil is well-aerated meaning that the roots get adequate oxygen supply. The same thing cannot be said about the nutrient reservoir in hydroponics, there is a deficiency in oxygen and it is for this reason that you need one of the best air pumps in your hydroponic system.

Concerns when using air pumps for hydroponics

Most hydroponic systems are used indoors since they are small enough to fit in available spaces and provide the convenience of easy monitoring. There is concern that quite a number of air pumps are rather noisy. This might impact on you directly by disturbing you as you sleep or work. Well, the good news is that not all hydroponic systems are noisy; you just have to be very selective on what you purchase.

Other than air pumps you will also need some tubing and an airstone. These are not always necessary but to sufficient supply of air to the roots you need them. In tubing, it is recommended that you use black tubes. This is due to the fact that bright colored tubes can become bleeding for algae that end up using the oxygen and nutrients meant for your plants.

An airstone is quite popular in aquaponics. It helps in the easy diffusion of oxygen on the water and ensures even distribution of oxygen. An airstone produces small bubbles that increase the level of diffusion of oxygen and this works well with air pumps. It is not always necessary to use airstone but it is recommended if you want to increase the solubility of oxygen in the mineral solution. The airstone should be placed at the center of the

Ways to increase oxygen solubility in a hydroponics system

  • Ensure that the nutrient solution is always evenly blended.
  • Don’t allow algae growth in the system
